On my dual booting laptop, I have Windows XP and Ubuntu 12.04. I've had XP on the laptop for years, and install Ubuntu 12.04 a few months ago. For some reason, Ubuntu 12.04 has stopped working.
When I power on the laptop, I get the grub menu, and I can select Windows XP or Ubuntu 12.04. If I select Windows XP, it boots up perfectly and I can use it as normal. However, if I select Ubuntu 12.04, It just displayed a terminal type blank screen with no text except the blinking cursor, but no commands execute if I try typing something in.
How do I fix this so I can boot back into Ubuntu 12.04? I know I can try a reinstall, but I don't want to lose the files I have in Ubuntu 12.04. Is it possible to somehow do a repair?
