I will most likely sound like pretty dumb saying this, but I was trying to install Ubuntu on a USB because my friend keeps telling me to, so I was installing it, and now it seems when I try get back onto Windows 7 it just comes up with a flashing white underline at the top left-hand corner of the screen. I haven't let that stay there too long so I don't know if it would eventually boot onto Windows or not? But looking at the install Ubuntu 12.04 LTS it says Ubuntu 12.04 is already installed on the hard drive and that so presumably I've wiped windows. Now, I would be happy to just keep Ubuntu but I did have Photoshop and things, if there's a way I can get Photoshop on Ubuntu then yeah I may be fine. But is there a way I can get back to Windows 7? My laptop came with it pre-installed so I don't have an installation disk so i'm not too sure if I can get it back if not I will probably just be able to buy windows 7 by February so it may not be too bad.
Thanks
NEW INFORMATION:
I started installing onto the USB, I made it bootable following the Ubuntu page instructions, and then when it came to making the partitions and things on the "something else" option on the install 12.04 LTS on the demo version of Ubuntu you can try on the USB,I must have accidentally clicked the wrong device for boot loader installation. I followed various instructions I found, but it seemed then (this was last night) I didn't realize it seemed to be saying it would install onto my hard drive not my USB like I wanted it to, thinking it was the USB I started the installation, realized i'd messed up, canceled it and now I don't seem to be able to use Windows
