I don't have the GRUB Recovery Screen due to a video card exchange. I asked for help about fixing that over a year ago, but have never had a response.
This 12.04 LTS hangs at boot time. I've spent the last 3 days on LiveUSB mode trying to fix it. It's come down to this:
I saw the number of old kernels a few days ago and started deleting about half of them. I was very very careful to not delete my
126.96.36.199-generic-pae ( or very close to those numbers I cannot recall the numbers, exactly).
or any with matching those numbers.
After those 20 or so old kernels were manually deleted, the OS would no longer boot. So here I am in LiveUSB and need help in deleting the out-of-date kernels. I could not perform that in boot-repair-disk session; even though it said I should. Maybe I'm not familiar with how it operates. It's my first use of it. Meanwhile in Boot-Repair-Disk the number of old kernels looked to be around 50, even though I though I manually deleted about half of them. And in another section of the Boot-Repair-Disk, under the heading GRUB, the old kernels were still there, too. I cannot post the RESULTS.txt as this forum says 49Kb is too large.
Can you explain how I can mount the hard-drive and somehow delete the old kernels and then start working on repairing GRUB2?
Also, please tell me the name of the folder (directory) where all the kernles are kept. For example: is that / OR /Boot or Bin -- with / being root, obviously?
I found a command line tutorial about removing old kernels with one line here:
