I think I have a BIOS-MBR and not UEFI because if I issue the command “ls /sys/firmware/efi”, I get ‘no such file or directory’.
I’m looking at the instructions for updating grub for BIOS-MBR and the first instruction is to “sudo grub-install /dev/sdy”. I know I need to replace “sdy” with my particular installation. I’m just not sure if I shoud use ‘sda’ or ‘sda1’.
Here is the info I get from “fdisk -l”:
fdisk -l
Disk /dev/sda: 698.65 GiB, 750156374016 bytes, 1465149168 sectors

/dev/sda6 1249982464 1250015231 32768 16M 82 Linux swap / Solaris
So, do I replace “sdy” with ‘sda’ or ‘sda1’?
Thanks.
