Anyone else having troubles reinstalling Mac OS X (and wiping WinXP)? I have a Mac mini Core Duo w/ 1 GB RAM, and have installed WinXP SP2 on it. I was very curious and just had to give it a go. This Mac is hooked up to an LCD TV (26", 1280 x 768 rez. @ 60 Hz), and just for laughs I wanted to see the XP desktop on it. Well, it all succeded very nicely. I used it for a couple of hours, mostly testing all the drivers that are starting to come out. After a while, I wanted to repartiton the drive (giving 50% of the diskspace to Windows was too generous IMHO), so I wanted to start all over. Inserted the Mac OS X Install DVD, booted off it, and repartitoned the HD. Once I've done that I wanted to install Mac OS X on the just created HFS+ volume, but the installer showed the red exclamation mark (on both partitons) that "Mac OS X could not be installed on this volume". I had seen this before, and usually after a reboot, and re-partiton it will work. Not this time! I have rebooted about 10 times..... Have resetted the NVRAM (as described here). Also turned the Mac off for 1.5 hours..... nothing! I keep getting that red exclamation mark.... I just wondered if anyone else had similar problems.
