I am puzzled by the need to use a vfat filesystem for a linux install.

I want to do a USB install of 6.2.1 and just boot from the usb.

My BIOS allows booting from USB, so I am unclear why vfat is required, rather than using ext2 or ext3.

I have searched for answers on the web and have drawn a blank.

If one has a Linux install as the only OS on a hard drive, we obviously expect to be able to boot it without making a vfat partition (or am I showing my gross ignorance).

Thanks in advance.
