    BSOD on boot: inaccessible_boot_device (Windows 10)

    Hi all, I recently disassembled my computer to clean it since it gets very dusty. For reference, this is not the first time I've taken my computer apart; I know how to correctly take it apart and put it back together. I made sure everything was connected properly and that nothing was broken/damaged. However, I think in the process, I must have somehow reset my BIOS in some weird way. Now, when I try to boot back into windows, i get a blue screen, a big frowny face, and the error: "inaccessible_boot_device".I know for a fact that I put everything back together the right way since I also have a 100gb Debian dual boot setup with GRUB bootloader, and I was able to boot into my Debian just fine, and everything works exactly as it should. I tried running the GRUB auto configuration thing, and it says it's able to find the windows .efi or something, but it doesn't change anything; the same inaccessible_boot_error appears when I try to boot into Windows.I've tried the diagnostic tools in the advanced recovery options, but nothing works. I'd like to avoid having to reset my entire computer if I can, so please, does anyone have any suggestions? Also, here is a snapshot of my system specs (taken from my Debian

    Assuming you have a UEFI partition check your BIOS settings and make sure the boot device is set to Drive C: Windows Boot Manager.

    If it's not UEFI then just change the boot option priority to C:

    Hi shadowfreud,

    Welcome to the 10forums :)

    Could you check in the BIOS if you see the storage device?
