I tried a couple bootloaders, and the net effect so far is I can only boot with the DVD in the drive, and it only gets me into installer. It installs just fine (both Leo4Allv3-10.5.2 and iPC OSx86 10.5.6 Intel AMD SSE2 SSE3) but won't boot into OS X...and now, I've lost my bootloader, and can't see my Windows installations either.

I think I'm done tonight...I'll restore my Windows XP partition, and leave it there for now. That SHOULD get me back into both XP and Vista.

I've just had no luck at all actually booting inot OS X.
