Hi there. I have a Lenovo Z575 and I installed the BIOS update on the Lenovo drivers page and now my computer wont boot. I tried to reinstall Windows 7 but it wont boot from USB, so I tried to install XP from a disc and it gets part way through set-up then i get a blue screen telling me Windows has shut down to prevent damage to my computer and the error it gives is IRQL_NOT_LESS_OR_EQUAL. However, I now have no operating system on my computer so can't use any of the fixes I find online. Oddly enough, it installs Ubuntu 10.04 that I have on a disc. It's only when i try to install Windows I get any errors.
I've already tried loading default settings in the BIOS with no luck. Is there another way to reset the BIOS?
