Problem with the boot disk is not resolvable.
Problem with the boot disk is not resolvable.
You're encountering an issue where the old M.2 500GB drive isn't recognized as a boot device on your new PC. This could be due to compatibility problems or incorrect settings. Check if the drive is properly seated, try a different USB port, and ensure the BIOS/UEFI settings allow the drive to be used. If it still doesn’t work, verify the drive’s firmware version matches your system requirements.
Are you sure your storage is protected? Does it use the original MBR, and is the new system booting without CSM active in UEFI? (If so, consider starting fresh with GPT)
I updated the UEFI to its default settings so CSM was disabled and it functioned previously, though I’m unsure what I did. After resetting, it restarted but still boots into BSOD. I don’t know the MBR or why it worked before but stopped suddenly. I tried resetting Windows on another PC, hoping it would help, but the issue persists.
