Been trying to upgrade my laptop to Windows 11 for the past few days now with very little success. Whether I use the install assistant or a USB formatted by the Media Creation Tool, the installation process keeps throwing up the INACCESSIBLE_BOOT_DEVICE error and reverting back again. I've tried various solutions to fix this problem, from updating or installing whatever programs I felt might impact the installation to resetting the settings on my BIOS. I want to avoid having to do a clean install and wiping my laptop if possible.
I've also been running SetupDiag and seeing if I can make sense of the logs, but I'm unfortunately not at all knowledgeable in this field. I'll put a link to the log.zip file from my latest install attempt here:

The computer should boot to the desktop when performing an in place upgrade repair.
There is no boot to a flash drive for an in place upgrade repair.
Please see the tutorial links for mounting the iso.
See if there is something useful in this Asus video on IRST and VMD:
I have some great news; after some searching, I found out how to disable VMD on my computer and switch it from RAID to AHCI. I had to set the computer to Safe Boot before going into the BIOS to disable the VMD controller mode. When it booted up, it automatically installed a AHCI driver in place of the VMD-based driver that was controlling the storage drive, after which I disabled safe boot and it booted up normally. This was the guide I ended up following: https://superuser.com/a/1359471
The Windows 10 in-place upgrade went without a hitch, and so did the Windows 11 upgrade! The VMD controller turned out to be the culprit behind the boot drive not being detected during installation. Thanks so much for helping me out!
Open administrative command prompt and copy and paste:

Reboot
Upgrade from 10 > 11 while in clean boot
If the bugcheck 7B reoccurs then a new partition may be a useful troubleshooting step.
If the drive is decrypted and the C: partition can shrink then a new EFI partition may be able to be created.
You know, I was getting tired of having to put in my recovery key every time Bitlocker popped up, so disabling it will at least make this easier, especially if it's been causing at least some of the issues I've been having. Was able to disable it, and decided to run by your list of commands again, with these results:
Please turn off bitlocker so that a new partition can be created as needed from C:.
