You will not need to redo all this every time you (re)compile a kernel 
if you're using grub, only add the new entry for the kernel in 
/boot/grub/grub.conf. With Lilo you will. The code in the MBR that Grub 
puts in allows it to access the boot partition and read the config, 
while lilo had to write it to the mbr every time you change things.

Install Lilo/Grub in the whatever partition /boot is on, then use dd, etc.

Take a look at: 
http://gentoo-wiki.com/HOWTO_Dual_Boot_from_Windows_Bootloader_%28NTLDR%29_and_why

It has all the info you need, and actually brings up the "bootable flag 
on the partition" question. I used this to put grub on my latest 
machine. I haven't needed to do anything to the NTLDR setup since the 
install, despite several kernel upgrades.
