I recently dual-booted my laptop with Ubuntu 14.04 and Windows 7. However, every time I try to start Ubuntu from Grub, it ends at a purple screen and the fan kicks on high. This is also the case when going into Recovery Mode. Windows, however, boots up fine. I did the same installation process on my desktop with no issues, however; can boot into both easily. The major difference between the two systems is that my laptop had Windows 8 pre-installed with EFI. I presume this had something to do with it. Though, I have turned secure boot off and made sure (as far as I know) it wasn't installing in EFI mode when I did the Windows 7 and 14.04 installations.

I looked this up on Google and these forums, tried a variety of things:

- boot-repair (which seemed to make things way worse) - reinstalled Ubuntu to no avail - checked FSTAB - updated drivers through CHROOT in Live USB - reinstalled Grub - NOMODESET - and wiped the GPT with fixdisk.

Wondering if anyone has any ideas on something else to try.
