Re: Probably silly Q about bootable partitions

[Roger Heflin]

rescue boot it, change the /boot mount line in /etc/fstab to add
noauto (like noauto,defaults...or whatever else you already have) and
change the last column to 0 to disable fsck on it.

It should boot then, and you have the machine fully up were you can do
better debugging.

ie mount /boot may give you a useful error, or it may work...if it
works that implies that in the initrd some piece needed to start /boot
is not there (fs mayb?).

/boot is only needed by the bios...it is not needed when the os is up
except to update teh booting kernel to a new one...
