Here goes, I had a dual boot system then I deinstalled Windows 7. I believe that Windows 7 leaves the boot loader so i ended up with.
Hard Drive 2: Bootable: Opening up the choise of OS between Windows 7 (even though Not installed hence my beliefe taht Win 7 leaves behind the boot loader). So on this screen I choose "earlier versions of windows and then it boots:
Hard Drive 1: Which has XP.
Since I wanted to clean this up I am trying a new install. Therefore I removed Hard Drive 2 and ran Win XP pro setup. Foolishly I believed someone who told me that there would be no problems. That XP would make HArd Drive one bootable and that then XP would install correctly.
I should perhaps note that I used a new copy of XP with service packs as I thought it would make more sense than the XP I've used previously which was the first version of XP.
Firstly, XP formatted the hard drive. Detected no problems. Then it copied across files. No Problem. Then on first loading XP I got the error message "Your BIOS" is not ACPI compliant. Contact Hardware Update.com to get update.
I have installed XP many many times on my system with exactly the same hardware and I have never got this message. Therefore I thought that maybe it was something to do with Windows 7 affecting the BIOS or maybe that XP with service packs conflicts with my motherboard. So I tried an earlier version of XP Pro that didn't have the service packs included.
Same message came up at the same time. On first running XP it gets to the Microsoft logo and then the same message comes up "BIOS not ACPI compliant."
At this point I thought that maybe the best thing would be to remove the CMOS battery. Clear the CMOS and therefore any bios setting would revert back to default and I could then proceed.
At this point when I rebooted the BIOS failed to detect the hard drive at all. I replaced it with another hard drive but still the BIOS doesn;t see a hard drive. I tried changing the SATA cables, changing which SATA port the drive connects too. I've now tested the hard drives in another PC and they are working.
So to recap:
BIOS doesn;t detect hard Drive.
Even when it did the XP installalation freezes at the fist run of XP saying BIOS not ACPI compliant.
As noted the hard drives worked before . I've reinstalled many times and never had any problems.
I am a total loss how to proceed. I've thought about flashing the BIOS with an update but since I've installed XP with exactly the same hard drive why should XP suddenly talk about ACPI. The BIOS not seeing a hard drive at all is weird. Even though I've changed SATA connectors on the hard drives and which connect to the Motherboard I'd expect it to see something.
ANy help very very much appreciated
