serious? wow, i'm impressed. I havn't tried to repartitin since redhat 7.x and back then i'm pretty sure they didn't, but if they have em now then i'm impressed.
Well there you go mate, take 43's advice and just do a defrag and install the distro. Personaly I recommend Mandrake, though I hear good things about SuSe (but you have to install from the net). I do like slackware though, but i dont know if it has repartition built into the install.
