So after many months, I decided to completely remove windows 7 from my laptop and replace it with ubuntu. Unfortunately, I got the common error of getting a hanging purple screen upon boot up. I couldn't even turn off my computer, holding the power button for a minute didn't even work. (I had to remove the battery from my laptop and unplug it. Horrible, I know) Frustrated, I lurked around various forums and wikis (such as this one). I did everything that could possibly effect my computer. I re-installed, typed in random commands under grub, etc. etc. However, after 15 attempts (and counting), my computer sort of just pooped out. Upon that purple screen, I can't even access the grub. So then I gave up and installed windows 7 again. Big mistake. My computer is beyond repair right now. I boot up in windows? I get the black screen of death complaining about a missing .sys file. Boot up in ubuntu? I can't do anything. Booting off of flashdrives seems to work though. What should I do? I am no tech-geek,(but I am slowly headed in that direction) so maybe I missed even the most basic thing.
Currently, my laptop is an HP-G72. Has and i3, came pre-installed with windows 7. It has no graphic card, and requires windows to install special drivers for properly display on the screen. Any help would be beyond greatly appreciated.
