I set up dual boot on my extra pc last night.
First installed windows 7 and that went just fine.
Downloaded Ubuntu and then did the MD5SUM and did not get a correct return that were listed on the site.
I forgot to do that before I burnt the image to a disc, so I booted from the disc anyway to do the intergrity check and no errors were found.
I then installed and everything seems fine except when it's booting, the purple screen is broken. should I try to redownload and re install?
