Is it possible to dual boot win 8 with xp? It was possible with the preview, but seems impossible with the actual version. I've tried various workarounds and get something like missing file ntldr, error code 0xc000000f. Had it working with vista/xp. Tried reinstalling xp, then repairing with the win 8 dvd. Repairing xp with the 8 dvd says its an upsupported option, and the fixmbr fixboot senario would corrupt the bcd.
