This is a brand new windows 8 system that was sold to a customer. He brought it in for being unable to boot into windows after having used it for a couple of weeks, and he demonstrated the issue to me. It literally just boots to grub. This customer is a basic windows user. No experience with linux or dual booting. He uses it for email. I have never come across this particular problem before, so I ran the normal partition tools to see if the table looked proper for a windows 8 machine. Everything checks out ok, however it is still booting to a grub prompt!!!!
