[Bug 1917278] [NEW] Unable to reinstall grub. Started with Windows 7. Installed Ubuntu 20.04 to dual boot. Upgraded to Windows 10. Got new monitor, did not recognize Ubuntu install. Reinstalled Ubuntu. Nothing works. Post here. Cry in corner.

[Andrew Stevens]

Public bug reported:

>From what I can see, the original boot loader was not UEFI, it was
legacy(not sure what that means).  There are 3 primary partitions for
windows and all Ubuntu was installed on an extended partition.  I think
the boot loader is the first primary partition that is 100 mb, but it is
ntfs, not fat32 like efi partitions should be.  Boot-repair doesn't work
either.
