-- Posted by Themakingofagod at 9:29 am on Oct. 21, 2008 I have Windows XP Professional, and due to an idiot comuter "expert" it didn't pass the validation test.  I went to Best Buy and bought a copy of Windows Vista to upgrade so it would be legit, and my computer refuses to recognize the upgrade disk. When I insert the disk, it reads it, then ejects the disk.  If I try to click on Drive E:\ (The disk drive) it gives me a loading screen, spits out the disk, then displays a blank drive. -- Posted by Elite Taste at 9:30 am on Oct. 21, 2008 Take it back and get it replaced. -- Posted by Themakingofagod at 9:32 am on Oct. 21, 2008 It's not the disk.  I tried putting it into my other computer and it recognized it almost instantly, the disk is not corrupt or malfunctioning. -- Posted by pleaseremove at 9:33 am on Oct. 21, 2008 Are you saying your copy of XP is illegal? Bear in mind for what you are doing although well meaning does not make it legal as to use an upgrade disk you must first have a legal copy of XP (hence the reduced price of the upgrade). I wonder if this is happening because it is detecting your XP copy isn't validating. Do you get any error messages? I would really have expected there to be one with this set of circumstances. -- Posted by Themakingofagod at 9:35 am on Oct. 21, 2008 It is.  I didn't get any kind of error message, no notification, nothing.  I basically treated it as though it was a corrupt disk, which isn't the case, because it works in my other computer.  Its not like it doesn't recognize the disk and sees it as an empty drive, otherwise it wouldn't spit it back out. -- Posted by Brunette lady at 9:48 am on Oct. 21, 2008 It may not even be the disk -- Posted by pleaseremove at 9:51 am on Oct. 21, 2008 In that case then I would say that the issue is your illegal copy of XP. Because that is illegal, you can't upgrade from it. You actually need a full licence for Vista in order to install. It doesn't sound like upgrade option is there for you with an illegal copy. -- Posted by rand0mguy at 11:52 pm on Dec. 26, 2008 can you not just boot from the disk?
