I had a BIOS mishap on a 5-year-old system which led me to an upgrade of mobo/CPU & RAM. Want to use my existing Win XP Pro installation, but having a dickens of a time getting into the existing partition, even with the ASUS AHCI drivers slipstreamed into my WinXP install CD. Anything I can do to avoid reformatting & reinstalling Windows? (have tried many things up to Hiren's BootCD 10.6 to no avail)
Go back into your BIOS and get rid of the AHCI, go to regular SATA/IDE.
Boot from the XP CD and perform a repair.
Sadly, whether set to IDE or AHCI in BIOS, the Windows Setup app sees a non-Windows partition on the drive and wants to repartition. Beyond any issues with the two motherboards & controllers, there should be no problems with the drive, so I was hoping against hope I could avoid the hassles of reinstallation, reconfiguration, recovery of oodles of updates & lots of software re-installation.. May have no other choice at this point..
