My issue is a little bit different than anything I've found so far on the forums. I had successfully installed Ubuntu on my Windows 8.1 hp laptop using the manual partitioning method (not the "install alongside windows 8" way). Today my Ubuntu was being weird and the mouse was blinking and all the text was resizing over and over again, and my shutdown button actually popped up the "lock" and "log out" options instead of the "shutdown" and "restart" options.
So I rebooted Ubuntu using LiveUSB and installed it again, and a message showed up saying "Ubuntu 14.04 detected", and the 2 options were "install Ubuntu 14.04 alongside Ubuntu 14.04" and "erase Ubuntu 14.04 and do a clean installation of it (or something like that)". I thought the second option would only affect my Ubuntu partition, so I selected it. Then I restarted my computer and found that my entire hardrive now was taken up by Ubuntu.
Is there a way for me to get back my windows partition? Would installing windows with LiveUSB and then restoring it with the backup I created work?
