Windows 10: Windows 11 Inaccessible Boot Device error and trying to recover data with Windows To Go...

My PC, Acer Aspire 5 Windows 11, has failed with Blue screen error "Inaccessible boot device" just after an update. Any of the recovery methods or canceling the last update didn't work. Now firstly I am trying to recover my data and then I will reinstall the windows. The first issue that I need your help is that using "Windows To Go 10 ISO USB" is compatible with my computer which has Windows 11 or do I have to use "Windows To Go 11 ISO". Secondly, after creating Bootable Windows USB, how can I recover my data located in my hard disk to an external harddisk. Your all help will be greatly appr

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.

Inaccessible boot device

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.

"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.
