I knew I'd leave out an important fine detail..
The problem I'm having -- (and where the Linux install crashes).. is with Disk Druid in particular.
I have the 10Gb free at the end of the HDD. I first create my Swap file.. and I try to create a Linux native partition that uses up all the available space, mount it onto the root directory (I don't need to create a particular partition for the /boot directory, hm ?).. and then Disk Druid complains that I'm over the 1024 cylinder, crashes, and exits.
.. mind you, I've installed the same distro', Redhat 7.1.. onto the same computer before and it's worked. The only difference is that now the primary partition is an NTFS one whereas beforehand it was FAT32.
Any ideas ?
