I recently bought a Toshiba C55-A-1N1 Laptop, and I can't get Ubuntu to install on it. It came pre-installed with Windows 8.
I have disabled fast boot in windows. Secure boot was already disabled in the BIOS (or UEFI or whatever it is).
I have tried only with the Live CD as I do not have a USB key at the moment. I have tried 13.10 and 12.04.4, both 64 bit.
After putting the disk in the drive, then starting the machine up, I do get to a GRUB screen. However before reaching grub, there are two screens. The first flashes up very quickly, and has some text in the top left which I cannot read. The second then stays up for about a second, and says:
error: variable root not set
Then GRUB loads. After selecting the option to try Ubuntu, or the option to install directly, the screen just goes black. I can hear the optical drive for a bit, but then that goes quiet.
I have tried increasing the screen brightness using the buttons on the keyboard (both with and without holding down the FN key - just in case).
The only thing that I can find online that seems similar is this http://forums.linuxmint.com/viewtopic.php?f=90&t=161388 which although it is for LinuxMint is the only thread that I can find for my exact model of laptop. Other Toshiba Satellite C55 models can have different hardware, such as AMD chips.
I have tried a few of the suggestions in that thread, such as adding options to the GRUB boot, but have had no results. I am not sure whether I am even applying them correctly.
Can anyone help at all?
My computer specifications are :
Core i5 4200m
8 GB Ram
Intel HD graphics 4600
Thank you in advance!
