Hi All,
I had a few 320gb sata drives that had OS X on them. Before that they were Windows for testing. I put them in an IBM eServer 335 and now trying to install CentOS 5.3
I get to the partition -> Create custom.
I take sda and create a swap and a software raid partition. Same with sdb
I then click Raid, mount at / and Raid1 (Mirroring)
I try to proceed and I get: boot partition is on a disk using GPT partitioning scheme but this machine cannot boot using GPT.
I have never seen this before.
Advice?

Sure, drop into a shell (boot to a rescue mode for example) and relabel the discs.
Use parted and its mklabel command and change it to msdos.

Can I do this from an install though? Or should I use a LiveCD? The drives in her ewont boot at this point.

The install DVD will let you boot to a "rescue" mode, instead of typing "linux". Once in that mode, skip net and install scan. Then when you drop in to a shell, go into parted. You are installing to sda IIRC? Try:
`parted -s /dev/sda -- mklabel msdos`
Me thinks, as your system is not functioning and I *assume* no data of value on any of the discs, you sure can't make it worse:)

boot the installl CD and get into the rescue shell (from the startup menu), then use something like
dd if=/dev/zero of=/dev/sda bs=1024 count=1024
note thats sda and not sda1 or whatever, we want the raw device and not the partition.
then reboot, and the disk should look like a virgin brand new drive. or from that same rescue shell, use parted/mklabel as he said above...
John,

Just the ticket!
