grub2

I am finally able to hibernate from my primary OS (windows 7) and boot into secondary os (Linux Mint 15) and vice versa. Steps required to do this setup: 1. Do a complete format and install Linux Mint ( or any other OS using GRUB2 boot loader) 2. Don't create a seperate partition to install...

The message showing while I am booting up:---> error: (hd0) out of disk Grub2 rescue> Inside my BIOS settings,all the HDD'S are shown O.K. in their S.M.A.R.T check and other status are normal as usual... What is the problem? Has the Grub2 gone corrupted?
