Hi. First time poster, long time reader. There is ALWAYS information on the net that gets me to my solution, however this time I am lost, and don't want to spend another 8 hours trying to figure this one out. Any assistance greatly appreciated.
I have screwed up my GRUB2 boot loader. I just get a flashing cursor when booting up. I am now booting up from a Ubuntu 13.04 64 bit USB key.
I have attempted running boot-repair a couple of times with the standard settings, a couple of times with the advanced settings. I have also tried manually reinstalling the grub and running update-grub... Following these instructions I have tried everything within my limited technical knowledge and a lot of googling.
Here is the output of my latest run:
Firstly, i acknowledge the partitions are a bit all over the place, as this is a lenovo X1 that had Windows 8 pre installed on it. I have moved a few partitions around, and Ubuntu was working fine, but i went in and changed some grub settings, confirmed they were working, then i changed something (i don't remember what specifically i changed) and it no longer works...
From looking at the URL of the report that was generated by the boot-repair tool, the issue seems that the boot loader is looking for the core.img at sector 235358208 but it’s actually at 108013576. Can i just change that? If so, how?
I am using my system in legacy mode (not EFI) and i have safe boot turned off.
