This is a strange problem I've had on two different laptops with
different flavors of Linux installed alongside Win XP. Here's the scenario:

Both machines will boot from a dead start into the chosen OS, be it XP
or Linux.

If I reboot the machine from XP to either OS the machine reboots normally.

If I attempt a reboot from Linux, the reboot fails. Grub doesn't load.
Black screen, no error messages. Nothing. I have to do a cold start to
get running again.

Here's my menu.lst:

*******************************
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from
0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default
entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved'
or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the
default entry
# (normally the first entry defined).
timeout 6

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
