http://askubuntu.com – Running Windows 7 on a ssd, giving it app. 18GB for install. When It tells me to reboot I do, and then it just goes to a black screen. I let it do this for about 20 minutes with no loading. I tried rebooting after that and it gave me the option to boot windows 7 and Ubuntu, but when i try to boot ubuntu I get a mauve screen and then it blinks and is just black for as long as i've cared to leave it. I'm running this as my system: intel i7 2700k 3.50GHz; 16GB 1600MHz Ram; NVIDIA GeForce GTX 570; My SSD has about 59GB free and my HHD has 1273 GB Free (HowTos)
