What is the exact failure message or behavior again? Saying it "stuck at ACPI core revision" isn't enough. Try now.
You may be able to get around such an ACPI error in the ACPI config settings.
This is after you get the prompt to "Press Any key to boot DVD" then files load, then it hangs at the Win7 Startup Animation?
And the Ubuntu and Partition Wizard Linux boot disks both hang at the exact same ACPI: Core revision?
Try disabling "USB BIOS Legacy Support" in the BIOS
Do you have PS2 keyboard?
If not use the battery method: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS
The fix was from Ubuntu forum for hangs on ACPI: Core Revision.
Try the install.
Likely the two Linux disks revealed the exact hang which is hidden in Win7 install by the boot animation.
