@ghali12345 was very clear that buying an external drive to backup data wasn't a financial option, so I think that would also rule out a new laptop as well. He said that the "pro", that may be able to help, is a family friend (i.e. free) so we'll wait and see how that goes. Anyhow, there was no indication that there is anything wrong with the current computer other than a messed up OS, so there's no need for a new computer. He's just trying to avoid doing a clean install (which may prove unavoidable).
