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.

Please boot from a LiveCD or USB drive and select 'Try Ubuntu' (not 'Install Ubuntu'), then when you get to the desktop, press CTRL+ALT+T to open a terminal window, then run sudo gparted - this is a partition editor tool. Don't make any changes to the partitions, simply take screenshots of what is displayed (or write the information down if you can't do a screenshot) and post back here for us so we can what your partition setup looks like. We need information on the number of partitions, the file system type (NTFS, ext4, etc.) for each partition and the size of the partition. –  Clive van Hilten May 26 '13 at 17:19
    
If you have more than one physical hard disc (unlikely in a laptop, I must say) then make sure you give us information on all of the partitions on all of the discs. –  Clive van Hilten May 26 '13 at 17:21
    
Add detail: Are you able to identify the graphics chipset? You may need to update (using text mode), or load an additional video driver. –  david6 May 27 '13 at 8:36
