+# 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.
