Reboot and Select Proper Boot Device – Explained With Solution

“Reboot And Select Proper Boot Device” is a BIOS Error message and it only occurs when your computer system’s BIOS is having some problem to find the System’s Drive or maybe some other Bootable Devices.

As it’s a BIOS Error, which means you can get this error message on any Operating System (like Windows 7 or Windows 10) and in any computer devices, which can be your Laptop or maybe your Desktop PC.

#Quick Tips:

  • In case, if you are getting this error while booting your bootable USB flash drive then it’s possible that the software what you use to make your pendrive bootable isn’t working on your computer. Just use some different one in order to boot that USB.
  • In case, you made new build for yourself or bought a new Computer for yourself and having this problem in that PC, then it’s quite possible that your computer or laptop don’t have any operating system installed in it. And yes, it also happens a lot when you installed a new Hard Drive or SSD into your computer.
  • If you having this problem randomly, or maybe your hard drive isn’t detected by the BIOS then it’s quite possible that your HDD got dead or having some problem in it.

Just continue to troubleshoot the error:

What Is “Reboot And Select Proper Boot Device” Means?

Mainly there is a chip soldered on your PC’s Motherboard called the “BIOS Chip”, and that chip is actually responsible for starting your Computer System, mainly from the beginning

In case If you don’t know, your Operating System is installed in your Computer’s Hard Disk Drive or a Solid State Drive (which depends on your PC) and that BIOS Chip is the one, who start the Operating System from your HDD/SSD and makes it running by using the Boot Volume.

And By showing the error name “Reboot and select proper boot device” or “Insert boot media in selected boot device and press a key” your BIOS is just trying to say, that it isn’t able to recognize your Computer’s Operating System Drive.

In case, if you are having this problem on a computer where not a single drive is connected to the computer’s main motherboard, then now I think you should need to connect one, and then install a proper Operating System in it.

Or otherwise, your computer’s screen will always show that error message on the POST display.

Just continue to read if you do have an OS (Operating System) installed in your system’s drive and still having this problem;

Why Do We Continuously Seeing This Error, Again And Again? 

Mainly, this error messeage shows right after on yoru computers starstup and sometimes, it just freeze your computer and keyboard your stops working and the same thing happens again and again whenevery time you starts your PC.

And just like I said, this error occurred when we remove or disconnect our OS Drive from the Computer’s Mainboard, but sometimes it’s also possible that this error occurs, even when you didn’t touch our Systems Drive.

Yes, it’s possible because sometimes our System’s Primary Storage Device cable connection get loose automatically due to long aging, and your HDD or SSD starts become not responding.

Or maybe it’s also possible that your Computer’s BIOS, automatically get reset too!!

Which can make your System’s BIOS to forget their Boot Selection Setting, causing not able to boot the main System’s Drive, mainly the one where your OS is installed.

In case if you don’t know about the Boot Selection Setting, then actually it’s a BIOS Setting Menu where we mainly select and arranges the Storage Drives which is connected to our computer, and tells BIOS to boot which particular bootable device at first or last.

Boot means Startup in computer’s language;

And there is one more reason for this error to shows up on your computer’s screen even when your System’s Drive or BIOS is working perfectly.

And actually, this one is the top most possible reason why you are getting this error and that reason is, the corrupted Operating System of your computer, or the corrupted Boot Volume of your Operating System.

and there are a lot of driffernt reson which can make yoru windows corrupted like a bad Windows or BIOS update or maybe a virus attack;

Any thing can be possibel but the thing is, in any condition, you can fix your Computer or Laptop;

So let’s see what is going to happen to your computer after following the ‘Troubleshooting Guide’ given below?

#First Thing First

Just like I said, mainly when our computer’s starts to operate, right after when you press the power button, it actually starts to scan every storage device which is connected to the computer.

When it’s find anything bootable connected to your mainboard besides your main System’s Drive, like something connected through the USB, then it’s also quite possible that your computer changed the boot sequence itself, and starts to showing this Error Message on your screen.

So, just make sure you do disconnect everything connected to your Computer’s USB Ports. Mainly the External Hard Drive, Pen Drive or any other kind of USB Disc Drive.

If problem not solved, just continue;

#Troubleshooting System’s Drive

If the above trick won’t works for you then now it’s totally your Computer System’s Drive related problem and right now it’s very important to troubleshoot your Computer’s OS Drive, in order to make things back to work.

So, the first thing which I wanted to you to do is to check your Computer’s Hard Disk Drive or maybe Solid State Drive is connected properly to your computer or not.

And you can easily do that by checking the Storage Device Connection Status in the computer’s BIOS, and that will definitely ensure you about the drive is working or disconnected.

To open your laptops or desktops BIOS Menu, you’ll need to hit the Del or F2 key on the keyboard again and again right after when you start your Computer System.

In case, If your computer is Powered ON right now, then now you’ll need to turn it OFF and then again turn it ON to do the Del or F2 key pressing procedure thing.

You can only do that while when you see the first black background type screen appears on your computer’s screen, right after when it’s Powered ON.

It’s also possible that your computer doesn’t open the BIOS Setup Screen even after hitting the Del or F2 key again and again on the keyboard.

It happens most of the times when your computer is having its own and some different predefined key to go to the BIOS Menu.

But the great thing is, you can actually check that predefined key on your computer’s start screen as shown in the picture given below.

After when your BIOS opens up, just go to the “Main Setting” or “Standard CMOS Features” or maybe some other BIOS option which can show you your all connected bootable devices like your system’s hard disk drive or an SSD.

You’ll find it easily because you just need to explore your BIOS Menu;

@What To Do – If Your Hard Disk or SSD Isn’t Listed In Bios (Skip This Step If It Appears Listed):

In case, If you aren’t able to find your OS’s Drive listed or mentioned in the BIOS Menu then it’s quite possible that your Hard disk Drive or Solid State Drive is not connected properly because of some faulty cable or maybe your main storage drive got dead.

Both of the things can be possible and to check what’s happen to your computer?

You’ll need to open your Computer’s Casing and change the SATA Cable with some new one.

Otherwise, at first, you can also try to disconnect the SATA cable from the old slot and reinsert it in some another free one.

And not just that, you can also try to change your Storage Drive’s Power Connector too.

To do that, just put out the main power cable connector from the storage device and then just put back some other one, which you can normally find coming from the PSU (Power Supply) of your computer, and one more thing you can’t replace any cable in laptops.

It can actually save you to buy a new cable;

I know sometimes replacing SATA Cable won’t works either, or it’s also possible that your laptop is having some problem to find the HDD/SSD in BIOS.

In both conditions, it’s 99% possible that your HDD/SSD drive got faulty and to confirm that, you can also try to use some other new or working HDD/SSD in your computer or laptop, only just for the testing purpose.

And yes, you can borrow it from your friend;

In case, when you actually found your HDD or SSD is dead, then you can check out these guide listed down below, which can help you to find out a new perfect storage drive for your laptop or computer.

@What To Do – If Your Hard Disk Appears Listed In Bios:

Mainly, a listed status of HDD or SSD in BIOS fully indicates that the storage drive of your computer is connected properly but the problem is coming from some other possible reasons, and those are:

  • BIOS “Boot Setting” Gets Changed.
  • Windows “Startup Process” Problem.
  • Windows Drive Got ‘Inactive’.
  • Windows “Master Boot Recode” Got Corrupted.

And to find out, your computer is suffering from which one of these conditions?

You’ll need to troubleshoot everything step by step in your computer to fix this “Reboot and select proper boot device” problem.

So, let’s find out;

Solution No. #1 – Fixing Boot Setting

Boot Setting is a BIOS boot configuration setting which allows your BIOS to boot all the connected bootable device in a proper sequence, which mainly preselected by the user or the computer manufacturer.

And the boot setting is all about, setting up the first boot priority to a Hard Disk Drive to start an OS, or maybe set the first boot priority to the USB or CD-ROM to boot and install an Operating System in a computer.

And by just changing the Boot Sequence or Boot Order to the First Boot Priority for your system’s Primary Storage Drive, like your HDD or SSD where you’re OS is installed, can actually fix this problem.

So, To Change Boot Setting:

  • Open your computer’s BIOS Setup:
  • Open the Boot Setting.
  • Set the 1st Boot Device Priority to your Hard Disk or SSD.
  • Save that setting and restart your computer.

If you wanted to check out the detailed steps about >>“How To Change the Boot Order”, Then Click Here<<

If changing Boot Setting won’t works for you, or maybe your 1st Boot Device Priority Setting is already pre-defined to your HDD/SSD.

In that case, you can move to the next step listed down below;

Actually, after this paragraph, this article only belongs to the Windows Users because I only listed solutions for Windows Operating System.

In case, if you are having some another Operating System installed on your computers, like a Linux or something, then I think now you should need to search the web and find the solution to fix your OS, and somehow if you still can’t able to find any solution to fix your OS, then you can also try to reinstall your OS and that will be definitely going to work for you.

Or otherwise, if you are using Windows OS then just continue to read.

Solution No. #2 – Fixing Windows Startup Problem

When our Windows Operating System is having some problem to start itself, then it’s surely possible that this error occurred on your screen and stop the whole booting process.

The best way to fix this kind of problem is that you’ll just need to perform a startup repair thing on your computer, mainly by using the Windows Operating Systems Installer Disc or USB, what you used when you installed your Windows.

I know sometimes it’s also possible that we don’t have the same Installer Disc or USB at this time.

But the thing is;

The Version of the OS in the Disc or in USB needed to be same to the OS what you are currently using in your computer and you can use any Windows Setup Disc or USB on your computer to use the Startup Repair Utility tool.

If you still don’t get it, then I actually mean use any Windows 7 Setup Disc/USB if you having Windows 7 installed in your PC or use any Windows 10 Setup Disk/USB if you’re using Windows 10 in your computer.

Link:>> Startup Repair – What It Is And How To Use It?

=> So, Let’s Overlook To The Procedure Of Startup Repair:

  1. First, you’ll need to boot your Windows Disk or USB by using the Boot Menu or Boot Sequence Priority.
  2. And right after when the “Press any key to boot from CD or DVD/USB” message appears on the screen, just press any key on the keyboard to continue, or to boot the Windows setup.

  1. Now you’ll need to go to the “Startup repair” or “Automatic repair” option, according to the version your windows because the procedure is quite different in different versions of Windows.

And now, you can click on the toggle down below, to expand the listed process steps according to the different version of Windows.

Solution No. 2.1 - Startup Repair for Windows Vista & 7

Note: Move to Solution No.2.2 for Windows 8 & 10 Startup repair procedure.

Right after when the setup booting process gets done, you’ll able the see the setup’s first menu options on the screen.

In that options;

You’ll just need to Click on the “Next” button and after that click on “Repair your computer” to start the “Startup Repair” utility tool.

After that, the setup will start to scan your computer’s drive and shows you your previously installed Operating System, in the “System Recovery Options” box.

Now, just select the listed OS and click on the “Next” button to start the Windows Startup Repair process.

In case, if you can’t able to find your Windows listed in that Box, then you can skip this solution and just move to the next one.

When the process gets started, you’ll need to wait until the startup repair gets complete.

Solution No.2.2 - Startup Repair for Windows 8/8.1 & 10

Right after when the setup booting process gets done, you’ll able the see the setup’s first menu options on the screen.

In that options;

You’ll just need to Click on the “Next” button and after that click on “Repair your computer” to start the “Startup Repair” utility tool.

After that, it will show you three options, but now you’ll only need to select the second one called “Troubleshoot”, and then right after when the second screen menu pops up, you’ll need to select the third option called “Advanced Options”.

Now select Startup Repair on Windows 10 or Automatic Repair on Windows 8 to repair your computer.

Solution No. #3 – Fixing Windows Inactive Drive

An Active Partition is a partition of your computer’s HDD/SSD which is also known by its other name, “Bootable Partition”.

That’s the partition who mainly contains your PC’s Operating System;

Normally only one partition can be active at a time, just like a C: Drive of your computer where normally Windows is installed.

Sometimes that partition got inactive due to some reasons like virus corruption or something else, but in that case, we’ll need to reactive the OS drive in order to start our PC.

And to do that, you’ll have to open the CMD Command Prompt on your Computer’s Screen, and then just input some commands in it to reactivate your Windows drive and yes, to start the OS properly.

I know your Windows isn’t working, and now you are wondering “how can I possibly open CMD in this condition?”, but the thing is;

You can actually, open CMD even outside your OS, and to do that you can follow this link which will show you >> 4 Different Ways to Run Cmd on Your Computer.

=> Open The Command Prompt On Your Screen & Then Type The Commands One By One What I’m All Listed Down Here:

  • Command #1diskpart
  • This command will start the Disk Part Utility in the Command Prompt and when the Diskpart starts, you’ll able to see the “DISKPART>” sign on the left side.
  • Command #2list disk
  • This will list all the connected drives of your computer.
  • Command #3select disk 0
  • In this step, you’ll need to select your main Hard Drive, mainly where your Window is installed. In my case, I’m selecting Disk 0 because that’s the only drive shown in my CMD, and that’s also the one where my OS is actually installed. It also possible to see more than 1 disk in the CMD, and mainly happens when you connected more than 1 Storage Drive to your computer.
  • Command #4list partition
  • This command will show you all the per-created partitions of that disk what you’ve selected.
  • Command #5select partition 2
  • Normally we select “Partition 2” because in most cases that is your Windows partition, but the important thing is, that really doesn’t prove that you’ll always need to select the ‘2nd Partition’ because sometimes “Partition 1” can be your Windows Partition too. So, I’m just only saying that select that partition where your windows actually is installed, and make sure you don’t select any 100 MB, 350 MB or 500 MB partition.
  • Command #6active
  • Now this command will make the partition active what you’ve selected in the above command.
  • Command #7exit
  • After that, just restart your computer system and test it.

Solution No. #4 – Fixing Windows Master Boot Recode

 photo alert-min_zpsz7khasfs.png

The MBR or I say Master Boot Recode, is the most important bootable data structure created in the OS Drive and that’s the thing which is fully responsible for guiding your system’s BIOS to compile which files to start the Windows Operating System.

The MBR is actually created during the process of Windows Installation and only needs to get repair when it got mainly corrupted.

It’s possible that your MBR got corrupted too, and it’s possible because of some recently installed Software, Viruses or some other OS/Software Updates, and it’s always better to get it repair as soon as possible.

Just like the above solution, this time you again need to use the CMD Command Prompt on your computer, because to fix the MBR you’ll definitely need to put some useful commands in the command prompt.

=> Here’s The List Of Command What You’ll Need To Enter:

  • Command 1# – Diskpart
  • Command 2# – List volume
  • Command 3# – Exit

Now you’ll need to find your Windows Drive letter in that list, like mine is ’29 GB’ ‘D: drive’ as shown in the example picture.

And after when you find what your Windows drive letter is, just use that drive letter in the next command which is given below:

  • Command 4# – D:  (Your Windows Drive Letter)  
  • Command 5# – Bootrec /fixmbr
  • Command 6# – Bootrec /fixboot
  • Command 8# – Chkdsk /f /r
  • Command 8# – Y
  • After when the “chkdsk” command gets completed, just restart your computer and I hope your problem is solved.
  • If not, then you can repeat this whole MBR repair process again and use this Bootrec /rebuildbcd” command before “Chkdsk /f /r” like in the given picture below:

@What To Do – If You Still Having This Problem:

If this problem still stuck on your computer then the only way to fix it, is to reinstall your Windows Operating System.

You can follow this link to see >> How To Install Windows On A Desktop Or Laptop Computer?

I know sometimes it’s also possible that you can’t be able to install windows on your computer because maybe you getting some error during the installation or maybe you don’t know how to install.

In that case, I think under 100 dollars you can actually hire a computer technician who can visit your home or office and fix your PC in front of you.

>>Click here, to get an estimated value of onsite computer technician service<<

@What To Do – If You Fixed This Problem:

If you successfully fixed your computer or laptop, then it’s really great and in case, if you don’t want to get this error ever again on your computer.

Then I can suggest you to use the top best registry tuner or cleaner in your computer system, because mainly this issue starts from a corrupted registry of your windows and there are so many of different reasons what can happen to corrupts your windows registry and most of are like, virus attack, installed spammy software etc.

If you don’t have any registry tuner or cleaner in your computer, then install a best in class cleaner in your PC to get the perfect performance and an error free system’s lifespan.

Here are two Top Rated Software’s what I recommend to all my websites guest users as listed below.

1st Best – Zookware Cleaner

2nd Best – CCleaner Professional

  3. Hoping you can help…
    Computer boots to windows 10 normally and will function normally for 30mins or longer then will suddenly reset (even if i am not using it at the time) and go to the reboot and select screen. If I power off and on using the on/off button, it will boot normally again. If I use the reset button it goes to the reboot and select screen. If I go to bios after resetting with the reset button, my hard rive is not shown at all. If I go to bios after a on/off button my hard rive is shown. Have done hardware isolation test except for power supply as I don’t have a spare. Any ideas? Thanks

    • This is me exactly!! Sometimes it will boot to windows, but eventually shut off and give the black screen about reboot/select drive.. It is so frustrating. It happens on other drives too. I have tried most of these fixes and I am still stuck. I think maybe my motherboard is bad? I even tried flashing it and clearing the cmos.

  4. my system is asking for reboot and select proper device ,it all started when i tried to delete system reserved and then my system asked for restart and after that it is showing this,my dvd drive is not connected to the system ,so in this condition can u tell me the process to come up with this problem

I can also read that my samsung ssd 29.8gb shows type/status(vol I’d) as cache disk (0). How to I resolve. This problem occurred a few days after I installed a software called diamond video capture. Not sure if this is what caused the problem. Can you help

  8. THis was a very informative article, but didn’t quite touch on a problem I am having: After I edit the BIOS to the correct order, something changes it back. My only boot record is on C. Also installed is another internal SATA drive and an external USB drive. These other drives are not bootable. The system will work fine for a few days, and will restart without error and then, I get the iselect proper boot device. When I go into BIOS, USB is now 1st, WD internal HDD is 2nd and ST HDD,( bootable drive) is third. I change the order to the correct order and then the process repeats in a few days. I’m lost. anyone have an idea?

  9. Hi
    i hope u can help
    i just made a bootable flash disk for windows 8.1
    it works correctly with other devices in that the language selection first step shows but on trying to boot on my desktop,a black screen shows for language selection followed by a series of what seems like a cmd prompting one to press enter or esc.

  10. I have this problem when starting the PC, after seeing the black screen and those reboot lines, I reset the CPU and Windows 10 starts normally. I also tried startup repair but it says that it can’t repair after diagnose. In BIOS, my hard drive is set as priority 1 so I don’t know what is wrong with my computer.

  11. This helped so much, thank you! I got this screen after I got a hard drive failure and selected F2 and randomly changed things in the BIOS menu without understanding what I was doing. (Seemed like a good idea at the time, but no). I expect to get the hard drive failure error again soon (Dell Inspiron 2020 running Windows 10). Do you have a repair guide for that, or should I just buy a new computer?
    Thanks again for writing this in a non-technical way so people like me can follow it!

  12. I’m getting the ‘reboot and select’ message. Compaq PC with Windows 7 about 6 years old. If I switch off the power at the plug for ten seconds then switch on the PC again it starts OK. I did once get a ‘primary hard disc failure’ message but then it worked after I switched the power off and on. Hard disc on the way out? Anything I can do please?

  13. I usually dont comment on the website but i just wanna tell u that ur method worked perfectly and thanks a lot .. it did helped a lot..

  19. Hello sir.. i have a question
    I have 2 PC, win xp and win 7
    I moved my win7 hdd to second partition on my xp.
    After i moved it back, my win7 cant boot, and i checked on win7 bios, but i cant found any hdd connected to it.but when i moved my win7 hdd to my xp, my hdd can reconize.. whats my problem? And which step i could try?

  20. What if sometimes windows 10 boots up and other times I get the Reboot and Select properboot device screen. Is that a faulty cable, bad drivers, or bad hard drive. Also I should add when windows does sign in it doesn’t let me do anything after that, the computer just keeps acting as if its loading and stays frozen. Thank you in advance!

  21. What to do if i buy a new hard disk, and i want to install windows 7 on it. But the system show me the error message when i startup my computer. This is the message error i see: “reboot and select proper boot device or insert boot media in selected device and press a key.”

  22. Hi there,
    in my case neither both hdd drives nor the dvd-drive are detected (and therefor I can’t conduct a windows-reinstallation via dvd). Could this be caused by a defect of the motherboard or by a software-malfunction as well (as far as I remember I did a “hard” system-shutdown by pressing the power-button a day before) ?
    many thanks in advance.

  23. Uh what if my laptop isn’t turning off in the first place? I wanna try the F2 or Del key thing but I can’t because my laptop isn’t shutting off it’s stuck on the same black screen that says a reboot device cannot be found… What should I do?

  24. Thank you for this guide! Took until the second to last option but that worked. I greatly appreciate the time and energy you put into helping others solve this problem. THANK YOU!!!

  25. Hi mate!
    My system crashed when I was playing a game – black screen GPU fans full speed. It was not the first time. But this time I came to the problem you have described to have fix for in this article.
    I did everything you said, nothing helped so far. Problem is that the last resort fix in Command promt Bootrec /rebuildbcd comes up with “Total identified Windows installations: 1 Add installations to boot list? Yes/No/All”,
    What ever I press it comes up with “The requested system device cannot be found”. On your screen Windows installations: 0.
    What do I do?
    Is there any hope, I can fix it or I have to reinstall the Windows?
    I believe that the initial problem is with my new GPU, because I never had any black screens with my previous GPU.
    Thanks in advance

  26. If you are running more than one hard drive, remove all but the one with the OS and reboot. I have three HDDs, and removed the two disk without the OS and my machine started without issue. One of the disks removed has problems.
