Solved Windows 11 Boot with Inaccessible boot device blue screen error

romiln · Jun 3, 2025

Additionally I created boot file by going into command prompt which was successfully done and it gave me an option to "Automatic repair" which I have seen after ages when rebooted.. although nothing worked out

Hmm, The screen shown winload.efi which is required to boot Windows from GPT disk.
For MBR disk, it should be winload.exe
Did you boot WINXPE with USB without UEFI Prefix ???
- Boot into WINXPE Again
- From Start Menu->All Programs->Administrative Tools then run: Disk Management. Take a screenshot
- Run AOMEI Partition, click on C: to get focus, take a screenshot
Post both screenshots for me.

Everything looks good.
One nore place to check: Boot to BIOS and double check if you have CSM enable

Here you go @Topgundcp

Hope all looks good. What should I do next?

From your BIOS. You have 2 entries from your Crucial SSD:
P2-CT1000BX...
Windows Boot Manager P2-CT1000BX...
Boot your PC to Boot Menu, select P2-CT1000... To boot from

Yes did that got error of "Start up repair".. shows 2 options - "Restart" & Advanced options. Restart won't fix anything and "advanced options" will show same 5 to 6 options.. so we are back to same where we started

The last thing we can try is:
- Download DismGUI++ from my google drive: https://drive.google.com/file/d/1M5ZiFkM49__b8grP83-pR7MwqtrBEWsq/view?usp=drive_link
- Unzip to the root of WINXPE then reboot to WINXPE, open This PC, locate Dism++x64.exe then run
- On top screen, You'll see 2 entries: X: and C: ,click on C:
- From Menu Recovery: run BootMgr Repair, run Scan Health, run restore Health

So It's not the boot problem. Your Windows system component is broken.
Do you have Windows 11 Installation Disk ?. If not you will need to download from:

Download Windows 11

Unzip to another USB drive, plug in and try: restore health again.

Running a Start UP Repair from the Windows Installer should fix the problem.
Make sure Windows Boot Manager is the First Boot Device in the Bios.

This is what I did

Downloaded Windows 11 in a different usb as a ISO.
Boot from Win XPE iso and apply image as ISO. Path was D:\ for image (not C) and target path was C:
Note that D drive is parition of windows ssd and C : drive here contains windows
Once I did step 2 and did restore health - it said the repair was done successfully.
Upon reboot from SSD didn't find same error
Now windows is going through fresh installation

I am wondering it should have repair existing installation why it is asking for fresh set up.

Topgundcp · Jun 4, 2025

You did not do correctly.
1. After download the ISO, you have to mount it then copy the content to the USB
2. Boot into WinXPE. Double click on This PC to identify which drive your Windows was installed, and which drive is your Windows Installation USB
3. Next, open the command prompt and type:

dism /image:C:\ /cleanup-image /restorehealth /source:J:\sources\install.wim:6 /ScratchDir:E: /limitaccess

This will fix corrupted Windows Components. The command above based on what I have in my PC.
- C: is my Windows
- J: is the USB containing Windows Installation
- E: is used for the Scratch Dir. This can be any drive in your PC, provide enough space for dism to work on.
- Index 6 is for Windows 11 Pro
Here's an example to run dism in WINXPE:

Thanks @Topgundcp for the help! Thanks for the awesome tools that you have shared here that have helped me in debugging my PC faster.

Hi,

I am getting the same error message about the inaccessible boot drive and the same other boot error screenshots.
I have so far tried every suggestion in this thread, I tried a Windows repair but cant seem to find such a thing
In winre non of the uninstall updates work, the system recover can find a recovery point but does not do anything
I'm up to trying to the last dism command.
My hardware seems fine, all my files seem to exist. chkdsk doesn't reveal any errors. Tried all the bcd/boot/efi commands
I have winxpe installed on a USB disk, I tried the macrium reflect thing
I ordered another USB and will install the win11 iso image onto that when it arrives later today
