I installed ubuntu following the steps in the linked question below except I used a live CD rather than a USB drive:
Now I am trying to follow the steps in the answer. I burned a CD of rEFInd as in step 1 but I cannot enter the firmware setup tool. How do I go about "setting a jumper to clear the NVRAM or temporarily unplugging the hard disk"?
To be clear: I have tried the answer that is all over askubuntu to
- set prefix and root to the linux partition (I verified this with "ls")
- run insmod
I get a file not found message for both linux.mod and normal.mod
Also, rebooting with the live CD in the drive does nothing. Rebooting with a windows USB recovery drive also does nothing.
