I have a laptop that has this version of windows. The laptop needs repair because it won't boot, but I need the CD (to boot from it and repair). I don't have it, I don't have a recovery disc either. I do have a windows pro version but I'm not gonna risk using that for repair. What version of windows would I need? Download MCE 2005, specifically OEM version or what? Here's my other problem, I'm not sure what version of MCE I have, SP1, SP2, SP3, not sure, well it's not really my laptop, it's my sister's, she doesn't remember. So say I download MCE 2005 SP3, and but the computer only has SP1, would it give me any problems when repairing the damaged system files? Thanks.
