Ok, so I already installed ubuntu 12.10 a little while ago and while trying to fix windows (main OS) microsoft had me do the start up repair which erased or made the boot manager disappear (not sure a little bit of a linux noob here). So i looked up instructions on how to reinstall it and when i went through the process and went to boot from the hard drive, the Grub 2.0 screen came up and has the GRUB> press tab for a list of commands thing and i have no idea what to do with that.
After that i went back and booted the usb up again and after clicking try ubuntu it now comes up with "installation encountered and error and will start the desktop so you can try to fix the error". Before that it also comes up with the box that says you have low space space with the options to examine or skip and before i can do anything brings up the installation error.
Then when i click ok to the installation error the screen blinks and it comes up saying im running in low graphics mode with a few options and i can't go anywhere from there. tried Ctrl Alt F1 to get into terminal but just brings me to a black screen with a line or couple (has been different on different boots) and no way to enter in commands (although i think you can type in it) but its not the normal terminal whatever it is. Not sure what to do here.
Looked through a bunch of threads on here with similar problems but most of them were actually installing ubuntu again, for the first time or something different. So thanks in advance to anyone that can share their knowledge of this problem. By the way, i'm not sure if theres a way, but im not able to boot into windows right now. I know the description is basic but i figured most of this stuff is familiar since there's many threads with this simaler problem but if anyone needs anymore details feel free to ask i'll be monitering.
