I would like to get Ubuntu on my old laptop (HP Compaq). So I ran the installation and it completed (I installed 13.04 with the Wubi installer). When I booted it up, it went to the login screen. This part gets weird: instead of it saying my username with a password box under it, it says Login: with a box under it. I type in my username and password and it says failed! It also says "localhost.localdomain" in the corner. I didn't install the server version of Ubuntu and im typing in the right username and password but it keeps saying failed. I can go to guest account but I can hardly do anything. I cant even configure my wireless settings! And for some reason Ubuntu corrupted Windows 7 that was on the computer because when I try to hit the option Windows 7 it says "starting windows" and that's it. What do I do? Is there a way without reinstalling Ubuntu? Any help would be greatly appreciated.
