Hi, I'm trying to help out a friend with his computer... he originally had Windows 98 on his computer, but when he went to college a friend loaded Windows XP on his computer because it's more recent. It was running fine but then he had a problem with the internet connection and put in his Windows 98 restore CD in to get his computer back to factory settings. But while it was restoring, it froze and it can't get past a certain point. Now, when he turns on the computer it says " No operating system found" and he can't do anything. What is the best solution? Should he buy an upgrade for XP? Or is there anything he might be able to do? Thanks so much in advance!!
