# This is a little helper script that tries to convert linux-style device
# names to grub-style. It's not very smart, so it
# probably won't work for more complicated setups.
#
# If it doesn't work for you, try installing grub manually:
#
# # mkdir -p /boot/grub
# # cp /usr/lib/grub/i386-pc/* /boot/grub/
#
# Then start up the 'grub' shell and run something like the following:
#
# grub> root (hd0,0)
# grub> setup (hd0)
#
# The "root" line should point to the partition your kernel is located on,
# /boot if you have a separate boot partition, otherwise your root (/).
#
# The "setup" line tells grub which disc/partition to install the
# bootloader to. In the example above, it will install to the MBR of the
# primary master hard drive.
