Windows 10: How do I fix Inaccesible Boot Device?

I've been trying to fix it these past few days and nothing seems to be working. It seems the problem is some corrupted windows files and that is preventing me from resetting my computer. I also tried to reinstall windows from USB device but I can't seem to do it because I keep getting stuck on the enter your password screen. I've entered every password that has been on my Microsoft account and none of them seem to be working. I've looked up how to fix it on windows 10 and when I try one of the solutions, it requires me to enter my password and it keeps saying it's incorrect, so I can't really

inaccesible boot device

Hi,

Thank you for contacting Microsoft Community. Your interest in Windows 10 is much appreciated.

The INACCESSIBLE_BOOT_DEVICE bug check frequently occurs because of a boot device failure. During I/O system initialization, the boot device driver might have failed to initialize the boot device (typically a hard disk).

You may follow the below steps and check if it helps.

• Run Chkdsk /f /r on the system partition. You must restart the computer before the disk scan begins. If you cannot start the computer because of the error, use the Recovery Console and run Chkdsk /r.
  
• If you cannot start the system in the last known good configuration, you should try to start off the Windows CD. Then, you can run Chkdsk from the Repair Console.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

"INACCESIBLE BOOT DEVICE" problems

Just started having "INACCESIBLE BOOT DEVICE" problems with my HP laptop when starting. Current wisdom seems to say this was related to upgrading to 10, but I upgraded a year ago. I did use upgrade instead of full install. Some statements here indicate
that not upgrading, rather than full install, leads to this problem after adding 10. What gives??

 

"INACCESIBLE BOOT DEVICE" problems

Hi John. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Inaccessible Boot Device error sometimes can be solved by resetting the BIOS or UEFI firmware to defaults:

Report back present settings for UEFI, CSM or Legacy BIOS, Secure Boot, and Boot Priority order - first place should be Windows Boot Manager for a UEFI BIOS or Windows hard drive for Legacy BIOS.

If not follow the standard steps to recover when WIndows cannot start below, and if necessary Advanced steps in this tutorial which includes everything:

1) Use whichever method works in this link to access Advanced Startup Options:
https://www.tenforums.com/tutorials/2294-advanc.... Easiest may be to restart PC three times to trigger the Startup Options.

2) If none of the other methods work it may be necessary to Create Windows 10 Installation Media on another PC:

http://windows.microsoft.com/en-us/windows-10/m...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key:
https://www.sysnative.com/forums/hardware-tutor...

Choose the boot device as a UEFI device if offered, then on second screen choose Repair Your Computer. If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

3) In the Advanced Troubleshooting options try to System Restore to a point before the problems began, Startup Repair, then if necessary from Startup Settings try to get into Safe Mode with Networking, or lastly Safe Mode.

If Startup Settings aren't available you can force Safe Mode from Command Prompt using the command to unhide F8 Advanced Startup Options here:

https://www.digitalcitizen.life/4-ways-boot-saf.... Try Last Known Good Configuration and then Safe Mode with Networking.

4) From Safe Mode w/Networking work through the Windows 10 Install Integrity Checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get donehttp://answers.microsoft.com/en-us/windows/wiki/windows_10-performance/windows-10-performance-and-install-integrity/75529fd4-fac7-4653-893a-dd8cd4b4db00:
If it doesn’t fix Windows enough to start it normally, then try a Windows 10 Refresh:

5) If Safe Mode doesn’t work or help stabilize things then return to Advanced Troubleshoot options. Next try Command Prompt to run through Windows 10 Install Integrity Checklist (above link) repair commands including sfc /scannow, DISM, a full Disk Check, or
return to Troubleshoot options to Reset Your Windows 10 PC.

6) Better yet do the vastly superior Clean Install Windows 10 following the steps in this link to delete all partitions down to Unallocated Space to get it cleanest:
