I simulated your situation in a virtual machine. The actual error that I received was 0xc000000e. (Notice the "e" at the end.) Please confirm because if one of my assumptions is wrong, the answer is wrong!
Unlike what you said, I successfully run Windows Setup without a problem. So, the most likely cause is that you did not give your computer an explicit command that says Boot from my Windows Setup media! This is especially correct if you do not see a message that reads "Press any key to boot from CD or DVD..."
So, once your computer is turned on or reset, repeatedly press Delete key to Enter your computer's BIOS Setup. (Your computer might need another key, like F2, F12, F8, etc. Check your computer's manual to find out or gaze at your computer's screen as turns on to see if it writes down the key that you need to press.) Once there, find a way to adjust the order of the devices that boot your computer. (Should be straightforward.) Make sure your DVD drive (in which you insert your Windows disc) is first. Alternatively, if your Windows Setup is on a USB flash drive, make sure that avenue has priority.
Once you get into Windows Setup, you can reinstall Windows... or change your UniqueID again. But I suspect you don't know your original UniqueID and there is no point going down that avenue.
