    I have a red bar appearing when trying to install windows 7 off DVD in UEFI mode , and a BSOD about ACPI when in legacy.

    I have No ACPI version option, though I read that it can help to lower the version from 5 to 4 or something. Or to select windows 7 optimization though I have no such option. Perhaps if there , they are old options.

    I wonder if maybe there is a BIOS update though.
