Have you considered doing a Clean Install of Windows 11? This would give the opportunity to wipe the drive of all partitions to get it cleanest down to the boot level.

The best Clean Install is here:

To create bootable Windows 11 installation media follow the steps under the section to Create Installation media in link Before you Start here: https://www.microsoft.com/en-in/software-downlo...

Power on the PC while pressing the BIOS Boot menu key given here:

Make sure during the booted install to unplug all other drives, boot the media as a UEFI Device, choose Custom Install, delete all partitions down to Unallocated Space to get it cleanest, choose the Unallocated Space, click Next to auto-create and -format the needed partitions and begin install - this makes it foolproof.

After install expedite all Windows Updates including Optional until no more are offered. Then import any drivers from the PC maker's Support Downloads web page for your model that are newer, or branded instead of generic. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.

Make it a diagnostic install by monitoring for the issue after you reinstall each app, Update, settings or any modifications. Have System Restore points set so you can roll back before the change that causes this, if you isolate it.

If you want me to look over your disk configuration to see if I spot anything (about half the time in thousands that I've read) post a screenshot of Disk Management, which I read like a doctor reads X-rays. Follow the steps here so I can see everything needed to advise you: http://answers.microsoft.com/en-us/windows/foru...

Report back results for each step so I know what else to suggest.

Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

 

"Inaccessible Boot Device" error

Hi Bill,

The Inaccessible Boot Device error is usually occurring if a device driver that the computer boot controller needs is corrupted. For us to provide an effective solution, we would need you to answer the following questions:

• Which build and edition of Windows 10 is currently installed on your computer?
• Can you boot the PC to the desktop?
• What update are you trying to uninstall?
• What error message are you getting when you are trying to uninstall the update?

Since you already performed the troubleshooting steps that you mentioned in your post, we suggest performing an in-place upgrade. This
article published by
PaulSey provides further information on how to perform an in-place upgrade with Windows 10. In-place upgrade can repair Windows system files and can give you an option to keep your program and personal files. Check if the same issue persists
after performing an in-place upgrade.

We are looking forward to your response.
