I have an unusual situation here on a system and thus cannot safely
follow the usual recommendation to rerun grub-install to address a
problem. At present my grub.cfg file appears to have a problem that I
am trying to correct, but I am having difficulty determining which
statement(s) are the cause of the issue. I have tried adding debug=all
but then get buried in output that is of no help determining which
statement is the problem. I would simply like a more detailed error
message that what I am seeing.
At present my system boots to a sh:grub> prompt and I must manually
issue a linux, initrd and boot to start the system. I have tried to
track this down as follows:
sh:grub> configfile /boot/grub/grub.cfg
<screen cleared>
error: Invalid mode: auto
<blank line>
Syntax error
Incorrect command
sh:grub>
Looking at my grub.cfg shows "auto" only one place:
set gfxmode=auto
Some searching shows that this is the default, so I edited grub.cfg to
remark this line out with the following results:
sh:grub> configfile /boot/grub/grub.cfg
error: No suitable mode found.
syntax error
Incorrect command
sh:grub>
I have also tried replacing "auto" with some specific modes, but I still
get the "No suitable mode found." message
This is of course annoying, but I can boot maya manually by specifying:
sh:grub>linux /boot/vmlinux.... root=/dev/sda14 ro
sh:grub>initrd /boot/init....
sh:grub>boot
Any suggestions what I need to do to get my menu back? Any idea why it
disappeared? Any further diagnostics I can run?
If it were another system I would likely simply try to
regenerate/reinstall grub, but given all the "fun" I had getting grub to
work here at all I would prefer another approach. The top line
identifes this as "GNU GRUB version 1.97~beta4" I am running.
