Configure Your NTLDR to Boot Any Linux Using GRUB...

?Requirements:

Firstly You Need The GRUB Package,which is installed by default in most distros.

and You should know which partition holds your /boot folder

Procedure:

--> To check Which partiton holds /boot this command helps you

??????? # mount /boot

?????? this shows the partition which holds the directory /boot???  

--> Now you need to make the /boot bootable, then create a file with first 512 bytes of

??????? /dev/hda1 (replace hda1 with the partition that #mount /boot gives you).

??????? Then enter this command 

??????? # grub-install /dev/hda1 

--> Now create 512 bytes file, 

??????? # dd if=/dev/hda1 of=/tmp/linux.bin count=1 

??????? This linux.bin file contains 512bytes of /dev/hda1 (Which contains Your Bootloader which you've installed)

???????? lets copy this file in your drive which contains boot.ini(Your Drive contains NTLDR)

???????? assuming it is the C drive mounted under /mnt/win_c

???????? #cp /tmp/linux.bin /mnt/win_c/linux.bin

?--> Now Switch to windows..

??????? Right Click on 'My Computer' and click on 'Properties'.

??????? choose 'Advanced' tab and the 'startup And Recovery' | settings' Then click on 'Edit'.

?--> Add the New Line At the end of file

??????? c:linux.bin="Your Linux name"

??????? (replace your c: with your drive where you've copied that linux.bin file)

?--> Save it and reboot the PC.

?--> Choose Windows in the linux boot screen, then choose linux again

??????? this should bring back to the linux boot screen. This is half battle won!!!

?--> In case you're getting the GRUB command prompt, type

??????? configfile /grub/grub.conf?????  

--> We now need to remove the linux boot loader from the master boot record

??????? and install NTLDR in its place.??????? 

??????? -->This will be done by booting windows installation disk.

??????? -->Now, choose the Recovery Console When Prompted.

??????? -->Choose Windows Installation, type your Password.At the prompt,type

??????????????? c:WINDOWS>fixboot????????????  

?????????????? followed by?????????????? 

?????????????? c:WINDOWS>fixmbr 

??????? -->It May warn you about the partition becomming un-accessible, you may ignore

?????????????? this and proceed normally.After doing so reboot the PC. 

--> And Now You are able to load your linux using NTLDR. 

--> Still choosing the linux option will first bring up the boot screen-you can remove

??????? that completely by making further changes to the /boot/grub/grub.conf file manually
