I was using my computer the other day when my house suddenly lost power so I immediately turned the switch off on my power supply so that my computer would be fine when the power goes back on and when the power went back on I turned it back on and it just goes to a blue screen that says "UNMOUNTABLE_BOOT_VOLUME" .. I have never had this problem before and have been using this computer for years. I already disabled auto restart on system failure so that I could read the message and post it here. I have a lot of data on my computer that I really do not want to lose and I do not have a windows cd nor do I have a friend who has one or who has a computer with a burner that I can use to burn a data dvd to fix my computer. There must be something I can do to get my computer working?? It's not even working in safe mode. I can't get a windows cd from the store until wednesday or thursday and it's very important that I have my computer from Friday and Saturday.. Open to all suggestions - Thanks
