Step 3 – Error Fix By changing Bios Setting

If this 0x0000007B or INACCESSIBLE BOOT DEVICE error comes on your screen while windows installation or windows boot up then maybe this little trick will solve your problem 80%, by just making a change in one single setting.

We got this error while installing windows because sometimes our computer doesn’t get recognize the hard drive while installing the setup, in that case, you can change your bios setting to boot the hard drive properly.

1. –  The first thing is to do is, open the BIOS Setup or CMOS Setup by pressing the Del or F2 key or you can follow the boot screen because the screen will show you what key you’ll need to press to open the BIOS Setup.

2. – Search for an SATA Mode or Chipset SATA mode in the bios setup. just like sShown in this picture:

3. – Change the setting to the IDE.

If your previous setting was pre-listed on IDE then you can change it to AHCI or some other options like RAID and after that try to use your computer again and test it properly.

It’s possible you’ll find the SATA setting options name changed a little bit because of the different version of bios, but the thing what I’m trying to say is “Change The SATA Mode” to make it work or you.

Here’s a picture below of some different version of bios where Sata mode is listed as SATA Operation setting and we changed the setting to ATA from ACHI.

4. – Save and Exit to the bios Setup.

5. – Try to reinstall your windows.

After doing these solutions and you still getting the same blue screen error, again and again, that means maybe your hard disk got broken. In that case, you can try to change your hard disk cable which is connected to the motherboard or you can also try to fully format your drive by using some 3rd party software.

Otherwise, you can use some different Hard disk to test It, if this problem really occurring just because of your previously installed hard drive.
