When I boot Ubuntu, it asks me if I want generic version, or recovery mode. I choose generic mode and it goes straight to a purple screen and doesn't do anything else. I love using ubuntu, but now I can't :(

If you have not already done so, you could try booting with the nomodeset kernel boot option and see if that helps.

Adding the nomodeset kernel option for a single boot

You can edit the boot instructions for the GRUB menu entry to add the nomodeset option to see if it corrects your graphics problem.

  1. Boot to the GRUB boot menu. An example of the menu is shown in the screenshot below.

    Note: If you do not see the GRUB boot menu when you boot, try pressing and holding the shift key immediately after the BIOS portion of the boot completes.
  2. Select (highlight) the GRUB boot menu entry for the Ubuntu kernel you wish to boot.
  3. Press e to edit the GRUB boot commands for the selected boot menu entry.
  4. Look near the bottom of the list of commands for lines similar to

    linux /boot/vmlinuz-3.2.0-24-generic root=UUID=bc6f8146-1523-46a6-8b\
    6a-64b819ccf2b7 ro quiet splash
    initrd /boot/initrd.img-3.2.0-24-generic

  5. Change the middle line in (4) by adding the kernel boot parameter nomodeset to the end of the line (i.e. after ro quiet splash).

    For this example you would change
    6a-64b819ccf2b7 ro quiet splash
    6a-64b819ccf2b7 ro quiet splash nomodeset

  6. Without leaving this GRUB edit screen, press either Ctrl+X or F10 to boot using the modified kernel options.

Note: These changes are not persistent. Any change to the kernel boot options made this way will only affect the next boot and only if you start that boot by pressing either Ctrl+X or F10 while still in GRUB edit mode.
