22 I made a typo my Bios is from around 2008 so it can not be EFI.
23 So I need a "BIOS boot partition" which in my case is "/dev/sda1" but I don't need the /dev/sda2 - this is my 128M boot partition.
24 My layout:
25
26 Device Start End Size Type
27 /dev/sda1 2048 6143 2M BIOS boot partition
28 /dev/sda2 6144 268287 128M Linux filesystem
29 /dev/sda3 268288 4462591 2G Linux swap
30 /dev/sda4 4462592 937703054 445G Linux filesystem
31
32 Can I combine sda1 and sda2? I mean delete both and create bigger sda1 make it a BIOS boot partition and format it as ext2; install grub2 on it.
