How do I make a boot loader load the existing boot loader from the first partition

Question

I installed ubuntu using wubi and then I tried installing grub 2 but it failed. I need a way to reinstall the mbr sp it will load the windows 7 loader from the first partition.

Answer 1

I don't know about Windows Vista (and later) particularities, but usually booting to Recovery Console and using "fixmbr" helped.

Also you can try to fix grub2 (may be by using of grub 1 or grub4dos) and making it chainload bootloader from the first partition (or NTDLR directly, if grub4dos can cope with Vista bootloader).
