Hi there. I bought an Acer Aspire 4530 from an acquaintance that when I got it had an unverified version of Windows 7 Ultimate on it. He found a keygen and it worked to verify it. The next day it was running super slow so I restarted it but it came back with status: 0xc000000f which I googled and its a boot issue. I do not have a disk for it and all the repairs I have came across require a disk to fix the issue. My boyfriend has a disk but its for Windows 7 home premium. Will that work? Both the laptop and my boyfriend's desktop are 64 bit.
