Computer won't boot to 64 bit OS
alright, so i solved the problem: i set the bios to "fail safe mode" and tried booting to my installation disc. this time, instead of a blank screen for all eternity, it showed an error code: 0xc0000225. i looked it up and didn't find much except that it's a generic error code' however' i did find a person who suggested turning on IOAPIC in bios, and it seems that before it was disabled, however, with fail safe mode on, it was enabled. the problem was that the MPS version (something that is only available when IOAPIC is on) was set to 1.1, and my computer needed version 1.4, so i set it to that and viola! everything works like it should again
my guess it that mps (MultiProcessor Specification) 1.1 only supports 32 bit processors, and thus forced my processor to run on 32 bit mode or something, hence it wouldn't run 64 bit apps, hence it won't install 64 bit OS's. also, one my DVD rom seems to be going bad, so i swapped it just to be sure.
