    Hello to all. I’ve been running vista ultimate successfully on my pc.
    Recently I replaced the hard drive and reloaded OS from same disc as I had used initially.
    On starting, I got the “Windows failed to load because the ACPI firmware (Bios)RSDP table is invalid”message.
    Since I’m using the same hardware and the same bios I’m at a loss to know what’s going on.
    I’ve done a fair bit of web searching but as usual all questions and no positive answers.
    Your comments on this would be greatly appreciated.
