I have a major issue, I had aquired a PC at no cost, but it had programs and info from the prior owner, and I was deleting programs and user accounts, in doing so, I had messed with the user log in, after restarting, so on the boot up screen, I had pushed esc to set the settings to its original settings, but in doing so, I had reverted it into its apparent Linux O.S, all I had wanted to do was to upgrade to Windows XP.
I cannot provide the computer model, or anything, only because I don't know it, but I would deeply appreciate all the help I can get to just get out of Linux and back to Windows. This computer isn't for me, it is for my family.
