My primary disk drive has 2 partitions:
Fist: Win XP Pro SP3 x86
Second: Win 7 Ultimate x64
I upgraded my pc with a DZ77GA-70K MB and Win 7 boots OK. Today, a week after I did the upgrade, I tried to boot my Win XP Pro SP3 partition and got bule screens indicating problems with PCI.SYS and SPTD.SYS.
I have tried to Normal Boot (does not work), Safe Boot (does not work), Boot with my original Win XP Disk (does not work).
I guess I am out of options. Any suggestion would be appreciated. My MB has the latest bios version as of today (Version 0064)
Never mind, problem solved. Had to change the chipset data mode from AHCI to IDE to make it work. Solved.
