So, when I went to do the update from 11.04 to 11.10 the install froze up, and now I cannot boot. I have a dual boot with Win7, and I can't get that to boot either.
I got frustrated and decided to just try a fresh install of 11.10. I did that, formatted the drive during the install, but I still get the same error:
error: incompatible license.
Entering rescue mode...
Today I tried to do a fresh install of 11.04, but I'm still getting this error. My computer has been out of commission since 11.10 came out, and I would love to get this fixed. I would have thought that doing a fresh install would wipe all traces of the old OS, but apparently not.
I tried various things I found googling, but to no avail. One was reinstalling GRUB from a live CD, but I could not get it to work. I don't know what else to do. All the information I've found is either really technical, or not exactly relevant. This thread
leads me to believe that it may be because I had added a second hard drive to this PC a couple months back. So maybe it's trying, or finding, part of an old install somewhere on the original HD. I don't know. Any help or suggestions are appreciated. Thanks!
