I was using the GUI install to try and install beta-2 on a 1.2 G hard drive. I wanted to make a root partition of 1.1 G and a swap partition of 100 M. However, I can't make a partition bigger than 504 M. It fails with the error message "Couldn't fit boot partition". However, if I make a 10 M /boot partition first I can make a big root partition after that. I assume that this is some 1024 cylinder limit for the /boot partition. It would be nice if there was a button on the error dialog box, "About this error", which would display something like: You have attempted to make a partition larger than the 1024 cylinder limit for the /boot partition. It is recommended that you make a small /boot partition before making the rest of your partitions. Or something like that.
Probably will address before GOLD release.
