Here is my boot-repair info:
http://paste.ubuntu.com/p/p9hPH8FvfK/
I had my system dual boot working like a charm. One 2TB disk.
- 300 GB partition for windows 10
- 175 GB partition for ubutu 18.04
- the rest an ntfs partition for shared data between the 2 os's
I had disabled Fast Startup in Windows 10 already (maybe some windows update turned it back on without me knowing?)
Windows and Ubuntu were installed with UEFI boot, grub would always load up and default to Ubuntu.
Today, a game froze on the Windows OS. I did a hard restart and now the system will not boot.
It goes to a "EFI Shell Version" info screen.
Starting up my live session ubuntu via dvd drive, boot-repair fails with an error:
- GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag).
However, I don't want bios mode booting.. I want EFI back.
I tried to repair windows with the windows installation DVD, but it just says 'Cannot repair windows'.
I notice in the boot-repair info from the pastebin above, it says:
- Grub-efi would not be selected by default because: no-win-efi
So is this because efi booting is all messed up for my windows installation? Is there a way to fix this other than reinstalling windows?
Thank you for any help you can give
