I highly recommend if you are installing Ubuntu that you have this BOOT REPAIR DISK before installing.

Its great to have handy anytime when your PC somehow fubars.
Its bailed me out several times over the years and with 20.04 when I was fooling with UEFI.
I had the impression that I could use EFI and gpt booting with my legacy BIOS where the BIOS
does not have a UEFI selection.

Boot Repair and gparted on the Ubuntu install DVD are two tools I recommend getting familiar with.

Using the 2nd option - install from a PPA in a normal live session - is preferable because newer.

Not a support request.
