Hello all. Happy New Year. That partition magic has a mind of its own, I tell you. My Grub
won't boot now, gives a #15 error. Grub starts, loads stage 1.5, then says something like
"Starting GRUB", then #15.
I have a multiboot PC with numerous windows and linux installations on it. I had used
cfdisk to make the partitions as I needed them, and in the extended partition they were in
a jumbled order ie sda6 then sda5 then sda8, 10, 9, etc.
I was in windows and added a partition sda14 at the end using Partition magic, and it went
ahead and changed the order by renaming all the partitions in the partition table and now
they are in the same physical order but cfdisk now shows them to be sda5 through 14 in
Using Knoppix, I see that all the partitions are still there, appear to be intact, but the
menu.lst in the most recent GRUB now has all the wrong device numbers. (I assume this is
the menu.lst GRUB is using, it looks like the one I was seeing on the menu page, though
each of the older linuxes also has its own grub and menu.lst)
So, as in prior posts I researched, I went in and edited the file so that all the (hd0,x)
point to the correct places, and assumed all would be fine. The "default" file which has a
single "9" in it I left alone, though I am not sure what that does, though I think that is
the old default not the new one.
I assumed that would work, but it doesn't. Given that the partitions are all named
differently now, how do I make sure that the GRUB is pointing at the correct menu.lstor can
even find it? Is there something else I have to do?
I am reading about update-grub and grub-install, but the instructions don't seem clear to
me. Please let me know what I am missing.
