Have fully formatted, not quick option, HDD and reinstalled XP. At bootup I now have 2 XP's in boot menu! I thought a full format removed everything so why have I got this? I have successfully resolved similar situation before by following the steps here: [URL]http://tweakhomepc.virtualave.net/dual/removedualboot.html[/URL] Only difference then was that the 2nd XP was on a different partition, this time they're on the same one, drive's not partitioned. The file "boot.ini" does not exist on this PC and yes I have searched hidden system files. I have an almost identical PC and "boot.ini" is on that in the root folder of C:, only real difference in the PC's is that this one has 2HDD's and a number of partitions. I have only installed XP, no chipset drivers or anything as yet. Selecting the 2nd XP PC boots normally, selecting 1st XP the PC boots slowly but to the new XP install, the old one doesn't exist. I don't know what's going on here and any advice appreciated, in particular why I have no "boot.ini".
