I have one SATA drive with windows xp installed. I added a second SATA drive to install CentOS on. During the install, both drives are listed. If I use the auto-partition feature and deselect the drive with windows on it, only selecting the new drive, I get an error message that it could not create the partitions. The same thing happened a few months ago and I manually setup to partitions. This worked, but windows wouldn't boot any longer. The last time I tried this was with CentOS 4.0. I'm reluctant to mess up the windows install and want to dual boot. Searching the web brought up alot of info, but I'm still confused as to whether this should work. I'm using an Abit AN8 motherboard with no ATA hard drives, but an ATA cdrom drive (used for the install). Any feedback is greatly appreciated. Thanks. mark markworkman@woh.rr.com ps. I do have a 3ware SATA card I could put in if that would make things easier.
