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

If you don’t find your hard disk listed or mention in your bios menu then it’s possible your Hard disk is not connected properly because of some faulty cable or maybe your Hard disk got dead.

You can also try to fixing it by changing your hard disk’s “SATA” or “IDE” cable which mainly connects your hard disk to the motherboard and most of the times replacing cable works and if it won’t work either then you should try to change the hard disk power connect with the other free connectors which were normally coming from the PSU (Power Supply).

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

Listed HDD in bios indicates, it’s connected properly but the problem is still coming from some other reasons and those reasons are:

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

#2 Fixing Windows Startup Problem.

 photo alert-min_zpsz7khasfs.pngWhen our windows start to having some problem while starting itself then it’s possible this error can occur on your screen and the best way to fix it by performing a startup repair utility by using your windows operating systems installer disc.

So, now I’m gonna teach you to fix your windows startup by a Windows Installation Disk (yes you can also use a bootable Windows Setup USB).

Only and only use your bootable disc or bootable pen drive according to your computer’s current installed operating system like, use windows 7 setup disc if you having windows 7 installed in your PC and use windows 8 setup disk if you’re using windows 8 in your computer.

  1. First, you’ll need to boot your Windows Disk or USB by boot menu or boot sequence priority. If you don’t know how to do this then these given link below will help you to boot your disk or flash drive.

#3 Fixing Windows Inactive Drive.

 photo alert-min_zpsz7khasfs.pngAn active partition is a partition in your computer’s hard disk which known as bootable partition who contain your PC’s operating system. Normally only one partition can be active at the time like c: drive where our windows is installed.

Sometimes that partition got inactive due to some reasons and we’ll need to reactive it in order to start our PC.

First, open cmd on your computer’s screen then type the command what I’m listed below:

there is link given below which will help you out to open cmd on your computer’s screen without an operating system.

4 Different Ways to Run Cmd on Your Computer?

Command #1 – diskpart

This command will start disk part utility in your command prompt. When diskpart will start you’ll able to see “DISKPART>” on the left side.

Command #2 – list disk

This will list all of your connected drives in your computer.

Command #3 – select disk 0

In this step, we’re selecting our main hard drive 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 installed.

Command #4 – list partition

This command will show you all the partitions created in that disk what you’ve selected.

Command #5 – select partition 2

Normally we are selecting partition 2 because that’s our windows partition but that not prove we will always need to select the 2nd one because sometimes partition 1 can be our windows partition too. So, select the partition where your windows is installed.

Note: Never Select 100 MB, 350 MB And 500 MB Partitions.

Command #6 – active

That will make your partition active.

Command #7 – exit

Now restart your computer and test it.

#4 Fixing Windows Master Boot Recode

 photo alert-min_zpsz7khasfs.pngThe MBR or I say master boot recode is the most important data structure on the disk which is mainly created when we make a partition in our hard disk to install windows.

It’s possible your boot volume got corrupted by some recently installed Software, Viruses or Windows/Software updates and it’s better to get it repair as soon as possible.

So, now we are using cmd command to repair our hard disk boot volume and now you’ll just need a cmd to type the command into the command prompt.

Command 1# – Diskpart

Command 2# – List volume

Command 3# – Exit

You’ll need to find your windows drive letter in that list, like mine is 29 GB D: drive.

Now you know what is your drive letter is, so just enter your drive letter in the command prompt and repeat the following command given below.

Command 4# – D:  (Your Windows Drive Letter)  

Command 5# – Bootrec /fixmbr

Command 6# – Bootrec /fixboot

Command 7# – Bootrec /rebuildbcd  {Skip this command only for the first time and use it if skipping this won’t works after testing but definitely use the chkdsk command written below in every try.}

Command 8# – Chkdsk  /f    (Try chkdsk /f /r If “Chkdsk /f” command Won’t Works)

Command 8# – Y

After “chkdsk” command completes, just restart your computer and I hope your problem is solved.
