I want to do as some people have suggested, install Vista RC1 on a seperate partition, because last time I had no end of trouble trying to delete the Beta2 O/S from within XP, with access denied messages etc, but if I installed on a partition then i'd just be able to delete it when I wanted to get rid of it. Thing is, Parition Magic won't let me create a partition above 2.5GB on my drive, even though there is 27GB available free space. Also, NTFS is selected, so it's not like I'm trying to create a FAT16 parition (which obviously Vista wouldn't support anyway) I have checked the drive for errors and there are none. What could be going on? Cheers

PM 8.0 with the update? If not get gparted on linux live cd.

Thanks for the reply, I got this sorted by changing the permission settings on my drive - they were all messed up as I had installed Vista on there before. No idea why that'd have restricted the parition size (and also, the max size offered was 25GB when I had 47GB free...) But oh well, done now.
