This is a bit confusing. I am assuming that you have a 20mb HDD or more, which has a 4 GB Primary followed by a HUGE extended, which has been broken into further extended-logical partitions. > > The Grub boot loader in selected to be installed on the first sec- > tor of the boot partition, but currently I am unable to boot to > Linux.The system directly boots to NT and if I make the Linux par- > tition as the boot partition then " mising Operatung System " mes- > sage is shown. > Your problem arises from the facts: a) Your MBR is still NT (since grub is installed on the 1st sector of the boot partition (i.e. the boot sector of Extended). b) Even if you change your bootable partition, things will not work from there since BIOS will still lead you to the MBR which does not take you to a valid NT boot process. c) The easiest solution for a dual boot at this stage would be to forget grub/ LILO and dual boot through NT boot.ini file. If you are not aware of the process have a look at: http://geocities.com/usmbish/hdi.html d) Alternatively, you need to put grub on MBR and set boot info correctly. > > I did get some error while assigning the root partition, but can- > not recollect the exact message. > It is not a good idea having a primary bootable OS totally on an extended logical. Since there is a physical gap between the actual / device and the extended boot record, an error may have been sent. If your Extended partition is /dev/hda4, and your root partition is at /dev/hda6, the boot record would be written at /dev/hda4. > > I think the primary partition need not be under the 1024 sectors > in new versions of LILO,and I thought same is the case with Grub, > right ? > Dead right.

Do a dual boot thru boot.ini file. If you have more experience on M$ than Lin, then it is likely, you will find this easier.
