This is an issue with Windows Boot Loader, not grub. As a courtesy, suggest booting into your Windows recovery environment and running bcdedit. If the output includes "device unknown" or "osdevice unknown", run:
bcdedit /set default device partiton=X: and bcdedit /set default osdevice partiton=X: , where X: represents the drive letter with your problematic OS in your recovery environment. You can find it by opening notepad and pressing save. If other devices are reported as "unknown", set the appropriate default as above. Note: your efi partition will likely be hidden. For further support I suggest forums focussed on issues with Windows. Cheers, On Sat, Nov 23, 2024 at 5:57 AM Brenton Billups <[email protected]> wrote: > Hello.
