Hi friends.

I had dual boot bt4 and windows 7. First, i had install windows 7 and then i installed Bt4 Everything was fine. but , i wanted windows 7 boot menu then with the help of windows 7 DVD I loaded windows 7 boot loader at bootup. Then Edited bcd in windows 7 and entered bt4 entry and earlier I already created Bt4 boot drive image through BT4 OS by "dd" Command. everything i did correct because i used to with fedora linux. But when open my pc then i choose "bt4" from windows boot menu then it do not start. Now i need to restore my Bt4 bootmenu(grubmenu) how can I ?. I know how to install grub but how can i put grub in mbr so bt4 boot menu comes again.
