Fedora Core Installation Problem - Partitioning

Hi all, I had tried several times to install FC1 using the graphical interface, but it kept on crashing after a few screens. So, I decided to try the 'linux text' boot command, which was OK until I started to setup the linux partitions using the Disk Druid. Here is the setup: I have two HDDs, the first HDD (HDD1) with Windows ME (primary partition) and a split extended partition. The second HDD (HDD2) has /boot, SWAP, /, (all primary) and a slip extended partition with /home, and other partitions in it. These were all setup using PowerQuest Partition Magic 8 (PM8). When I manually partitioned the Linux partitions on HDD2 and installed GRUB in the MBR of HDD1, I had noticed that Disk Druid and Partition Magic 8 have a big incompatibility problem - it corrupted one of my partitions in the extended partition on HDD1. When I went back into windows, PM8 showed HDD1 as one big BAD yellow partition. Anyway, in the end I had to delete and recreate the corrupt partition, BUT, I'm a bit worried about attempting to re-install FC1. I would like to know: Has anybody had a similar experience at all ? And is there a way around this problem ? Is this a known problem in general with FC1 and PM8 ? I would appreciate all the help ! Kind regards, Jules
