Thanks for the info, I'm not worried about the RAID at this point, infact form a Bios perspective, I've removed the RAID0 array, and have the BIOS presenting the disks as two non-raid member discs, that is, they are just two SATA drives at 500GB each.

My PC is:

Dell Dimension 9200
Intel Core 2 Duo - 2.4Ghz (?)
2 x 500GB SATA 2 drives
Nvidia 7900
4Gb Ram

So, based on your earlier directions about deleting the partitions, when I go and right-click on the disk in the left pane, and select erase, it still asks me for a name when I delete it, I believe this is much what I've done, except my partition will now be called unnamed as opposed to leopard.

I've tried the install with a fresh partition, without messing with the Chalmelon installer, I'll give this a try again, and post responses back.

I don't mind booting off of the DVD, it actually goes pretty quickly, but I'll endeavor to make a USB boot stick and try it as well.

Thanks
Greg
