I've used grub before, so if it's smart enough to find all available
bootable partitions I don't need a GUI just to make my selection on boot
I'll make sure that I use Clonezilla before I do any second OS install,
just in case!
PS What's the recommended file system around here? Is ext4 the way to
go? Or maybe xfs (if I've remembered the name of that correctly. I don't
plan on setting up LVM (it that's what I think it is .. making as many
drives as you want appearing like one big drive, right?) as I'm used to
just putting different types of files on separate partitions. I have a
250Gb drive and a 2TB drive.
