Linux Mint 20 insists on EFI boot? Why?
by steveis2 from LinuxQuestions.org on (#559RH)
Hi,
There are three disks on my PC one for data and one for win10 and one for Linux. The system duel boots between LM19.3 and win10.
I was in the process of installing LM20 onto the disk with LM19.3 on it when at the point at which I clicked the install button a warning came up saying that no EFI partition was in place and the system might not boot if I continued at my own risk. I decided not to continue.
When I installed LM19.3 there was no such question or warning. I was able to install grub on the disk I was installing LM19.3 to and then pick it up via bcd on booting up. I seem to remember a similar situation quite a while back with an earlier version of Mint but don't know what the solution was. All my disks are MBR and I don't want to have to use EFI to boot Mint. If I were to 'continue at my own risk' I think I'd end up with a mangled disk.
Is there a solution that anyone can suggest that avoids the use of anything EFI?
Regards Steve
