I figured out the solution. To reinstall the grub you need to do grub-install /dev/hda This will write the stage1 to the MBR.

I built the binaries. Doing make, make check, make install did not install this GRUB version (0.90..), my old gnu version (0.93) is what gets loaded when I restart the machine. I also ran the grub-install file from build/util directory: ./grub-install /dev/hda6 Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'. # this device map was generated by anaconda (fd0) /dev/fd0 (hd0) /dev/hda /dev/hda6 is where my " / " mounted. After this also my old grub is being loaded. I then manually changed the files in /boot/grub, /sbin/grub, /usr/bin/mbchk, but still no luck. I need this GRUB version to boot the L4Linux-fiasco from my hard-drive. What do I have to do to get my laptop (Pentium M) load this new GRUB? Thanks, Jayesh
