You need to install your bootloader on the MBR on hda usually.
With grub
Boot with floopy, login as root and type
Code:
grub
root (hd3,0)
setup (hd0)
quit
Thats if /boot is the first partition on your disk. if not change (hd3,0) to the correct partition.
Rember Grub counts from 0 not 1 so hdd2 would be (hd3,1).
Logical Volumes start at 4.
