12 If you want t be able to use UEFI, you need to use GPT. UEFI needs a FAT
13 partition at the start of the drive, type FE00, but booting a GPT disk
14 with MBR requires a small BIOS boot partition, type EF02, at the start of
15 the drive (mine is 1MB).
16
17 For ease of switching to UEFI later, I'd do
18
19 sda1 1MB BIOS boot, type EF00
20 sda2 /boot, type 8300
21 everything else.
22
23 You can make sda2 ext2, then, when it is time to switch, simply backup
24 the contents of /boot, replace sda1 and sda2 with a single EF00
25 partition, formatted with FAT, and copy the contents of /boot back.

31 How is it that we put man on the moon before we figured out it would be a
32 good idea to put wheels on luggage?
