+grub-setup fails after Attempting to install GRUB to a partition instead of the MBR?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea.
+ grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.
+ grub-setup: error: Cannot read `/grub/core.img' correctly
+
+appears because recent grub2 versions sadly introduced a regression which avoids
+that grub is being installed into a partition (PBR, Partition Boot Record)
+instead of MBR (Master Boot Record).
+
+To work around this issue you can install grub into the MBR (Master Boot Record)
+using the '--grub-mbr' option of grml2usb or switch to syslinux as bootmanager
+(just drop the '--grub' option).
+
+To fix this issue manually you can also execute (adjust '/dev/sdX' to your
+device of course):
+
+ mount /dev/sdX1 /mnt/test
+ grub-install --force --recheck --no-floppy --root-directory=/mnt/test /dev/sdX
