Rc Loader If I Delete The Partition For Ubuntu, Will The GRUB Loader Still Be Intact And Working Fine?

If I delete the partition for Ubuntu, will the GRUB loader still be intact and working fine? - rc loader

I have a Vista / Ubuntu dual-boot set up, I wanted to delete my Ubuntu partition, and by the RC of Windows 7 is replaced, and I wondered if I could GRUB without having to keep problems?

Thanks for the answers!
