I kind of did this.

I installed F11 to a raid-1 two sata drives.
I could not get it to boot, it wanted a BIOS ID.
My BIOS (MSI K9A2) lets me boot from raid, but it does not show up in the first screen.
The one with IDE/SATA drives shown.

Anyway I went into the BIOS and deleted the raid array.
When I tried to install F11 the drives were NOT detected by anaconda.

It seems that there are "ghost" dm partitions on them.
Anaconda sees them and dies.

I was able to install F10 and Mint, as well as XPx64, but not F11 or F12-alpha.

Apparently this is a known bug in anaconda.

So you may be able to fix up your drive and boot it, you most likely will not be able to install to it.
