Thanks for you patience...

Device Boot Start End Blocks Id System /dev/sda1 2 1403 11261565 7 HPFS/NTFS /dev/sda2 1404 1534 1052257+ 82 Linux swap / Solaris /dev/sda3 * 1535 5995 35832982+ 83 Linux /dev/sda4 5996 6930 7510387+ 83 Linux

Currently, /boot/grub/ refers back to /dev/sda3. or hd0,2. /dev/sdsa4 is grml, where I would like grub to look for the /boot file, as I am going to remove /dev/sda3 as an OS and use it for data.

Best, M
