I've dual booted Ubuntu and Windows for years now and I've installed OSx86 on a separate drive which Grub2 picked up automagically and everything has been working great -- except I'm out of space.
So I bought a 1.5 TB drive and installed win7 into sda1 (100MB NTFS bootloader for windows) and sda2 (50 GB NTFS windows drive). I now want to install two or three flavors of Linux. I'm thinking Ubuntu 10.04, Debian 5.05, and (if I'm bold enough) gentoo. each in 50GB partitions. I've already partitioned the drive a bit putting a 1.2 TB shared NTFS partition at the end (sda10), and a 2 GB swap parition just before that(sda9)
My questions are:
(1) can all my linux distro's share that 2GB swap, or does each need it's own dedicated swap partition (installers generally assume you do)?
(2) can I re-partition space in the middle of the drive without messing with windows(sda1&2) and the shared part. (sda10)?
