Re: When I try to boot windows, I get an error message
Go into the BIOS and check for plug and play options; there's usually something like "Plug and Play OS". It's basically deprecated when a modern Windows version is being used with ACPI enabled, but if ACPI is off, it has an effect. So, if the BIOS supports ACPI (it would be have to be a pretty old computer not to support it), it might have something to do with it.

First, I'd try booting with PnP OS off and ACPI on. (This is the configuration that you ought to be using on most modern computers.)

Now, if ACPI was on, and Windows crashes with 0x000000CA, it might have something to do with a bad ACPI driver under Windows. In that case, turn ACPI off and turn PnP OS on. This will revert to the Windows 95-era plug and play autoconfiguration, but ought to still work.

If that doesn't work, go into the BIOS and disable as many non-essential hardware devices as you can. Try booting. Then re-enable devices a few at a time until you either reproduce the error or it works.

I'm surprised this happened all of a sudden. Are you sure you didn't plug in or add any hardware or drivers recently?

Also, I don't know how well this particular version of Linux supports messing with ACPI settings...I can't make any guarantees that Ubuntu will still boot.
