Tried installing ubuntu today, had a host of problems, here's what I did step by step and the resulting problems.
downloaded and setup refit
disk utility wasn't working to repartition, so used gparted off ubuntu cd to repartition my OS X partition, leaving ubuntu about 30 gigs to install to.
Formatted empty 30 gigs as ext3 and installed ubuntu onto it.
rebooted, windows no longer in refit list
attempted to boot ubuntu, got a black screen with a flashing _.
synced partition tables with refit as suggested in FAQ, now it just hangs at the picture of tux when i try and boot ubuntu from refit
Still unable to boot windows, windows partition labelled as disk0s3 in disk utility, verify and repair both unsuccessful, can't even access files.
os x still boots fine.
any suggestions to get windows and ubuntu working?
its windows vista ultimate and a 2007 aluminum imac if that helps.
