This question already has an answer here:
I'm a bit of a noob, so bare with me here.
I'm running a Toshiba Qosmio V1.32002.
I have had a dual booted Win8/Ubuntu 13.10 traditionally, and I recently upgraded to 14.04.
Now when I start my computer, the grub bootloader doesn't even pop up and goes straight to starting up Win8. Any idea as to how I could go about bringing my Ubuntu back from the dead here?
I've been seeing a lot of people talk about how grub errors pop up, and that simply isn't even happening in this case.
