I recently bought a new laptop which came preinstalled with Windows 8 (no! please don't run away yet!). I'd like to try and put Linux on it in a dual boot (probably Ubuntu, with its UEFI support), but before that I'd like to make a system image with Clonezilla in case I mess up, or in the more likely case that UEFI causes something else to mess up.
Te problem is that when I put the Clonezilla CD in the drive and reboot, I get its GRUB menu, but after selecting an option the screen just goes black and stays that way. It still responds to a CTRL+ALT+DELETE at that point. I tried both stable-amd64 and alt-stable-amd64 to no avail. I have also tried 800x600, 1024x768 and safe graphics mode.
I have secure boot disabled. The system is an MSI GP60 2OD. Any help would be appreciated.
Update
It would appear that this problem not only occurs when trying to boot Clonezilla, but with any Linux-based system. It simply won't boot.
The only thing I notice is the orange light that indicates NVidia Optimus is using the NVidia GPU (or in Windows, that's what it indicates, anyway). Also, the fans get louder and the air coming out of the side gets hotter. The system is not completely frozen, seeing as pressing the power button, CTRL+ALT+DELETE or the fan boost button still does what I'd expect it to do.
I can boot a Linux live CD when I put UEFI into Legacy mode, but then I can't boot Windows, and I need them both.
Update
I managed to install elementary OS (based on Ubuntu 12.04) in Legacy mode, installing the boot loader on the root partition (/dev/sda9) to avoid it completely messing up the Windows boot loader. At the end the Windows boot loader still got messed up, but I managed to restore it. Now, when I put UEFI in Legacy mode, it doesn't find an operating system. And when I put it in UEFI (with CSM) it boots Windows 8.1. I tried adding an entry for elementary OS in the Windows boot loader with EasyBCD, but to no avail (the option appears in teh boot loader, but it just shows me an error about some file missing or being corrupted). Can anyone tell me if there's any way for me to add elementary OS to the Windows boot loader? Other options are welcome, too. Although this would be the preferable scenario because I would get to keep Fast Boot.
