Lemme see if I can sort this in my own head Apols if I'm reading this all wrong
Unfortunately, you are reading it all wrong. So perhaps I didn't phrase it all correctly.
Let me try again.
I have a Gateway notebook computer. It has 2010 installed in a dual boot with windows Vista home. The kernel = 126.96.36.199-pclos2.bfs
I decided to add a new kernel. 188.8.131.52-BFS. I rebooted and expected it to be automagically entered into the boot menu. It didn't show up.
I went into PCC (Configure Your Computer) System >> Boot. When I click boot, to throws up a error window and aborts. See attached screengrab.
You can see the message I get from cat /var/log/messages. It mentions a sdb drive when I don't have one. my drive for windows and pclinuxos = sda
Here is my menu.lst
color black/cyan yellow/cyan

tmpfs 1.5G 0 1.5G 0% /dev/shm
The first error I see is:-
is_geometry_valid_for_the_partition_table failed for (sda1, 20973567): 1023,254,62 vs 1023,138,48 with geometry 24321/255/63
Then it starts a series with this:-
ERROR: unknown device /dev/sdb5 (computed from (hd0,4)/boot/gfxmenu)
which is strange as my single/only drive = sda, not sdb. NOTE: it talks about being computed from /boot/gfxmenu.
I've found some stuff. In /boot/grub cat device.map
Also in /boot ls -al
drwxr-xr-x 3 root root 4096 2010-07-14 12:28 ./
drwxr-xr-x 24 root root 4096 2010-07-14 12:28 ../

-rw-r--r-- 1 root root 440 2010-04-27 21:58 boot.backup.sdb
Where did this sdb come from and if I move/rename it, will it break my system and where did it come from ?
