I've had this same Windows installation for numerous years running on a Samsung SSD. I decided to go out and buy an NVMe drive to install Debian on. Installation went well with no issues and I've been running and setting up Debian for a couple days. Today I tried going back to Windows and encountered a boot loop.
My first thought was perhaps I messed up the partion-table for Debian, selecting UEFI instead of Legacy MBR (which my Windows is running as). After confirmation they're both msdos I moved on.
- Windows Startup repair is unable to resolve the error and fails
- Windows System Restore failed
- Windows Live CD Startup repair failed with an error
- Tried disabling Fast Boot in BIOS
- Disabled UEFI in BIOS entirely
- Tried different menu-entries for Grub
- Tried boot repair (both recommended and manual)
- Tried bootrec /fixmbr
- Tried bootrec /fixboot (access denied)
- Tried Lilo to rebuild MBR
Despite everything I have tried, I'm still unable to get Windows to boot. Any advice?
