Help! Dual Booting Windows 10 After Installing Windows 11 Leads to Inaccessible Boot Device

Hey everyone! Hope you're all doing well! I currently have Windows 11 installed on one partition and everything's working great. However, I need to run Windows 10, so I shrank the existing partition and installed Windows 10 on the newly created unallocated space. At first, it worked fine and I was able to restart a few times, but now I'm getting the 'inaccessible boot device' error whenever I try to boot into Windows 10. I've attempted to resolve it by removing the boot entry from Windows 11's msconfig and recreating it using EasyBCD and EasyUEFI, but I'm still facing the same issue. I even booted the Windows 10 installer to execute the command `bcdboot c:windows /s S: /f UEFI`, but no luck. Can anyone shed some light on what might be going wrong or how I can fix this? I've been using Windows for ages, since 2003, and this has me stumped! Even if I can just boot straight into Windows 10, I can always add Windows 11 later with EasyBCD. Thanks a lot!

Have you tried checking your BIOS settings? Switching the storage mode between AHCI and RAID could help resolve boot issues like this. It might be worth toggling it to see if that solves the problem! Just make sure you switch it back if you're not using RAID.

I heard about that before. If I'm on AHCI and switch to RAID without actually using RAID, wouldn’t that mess things up?
