I use a dual boot with two hard disks and two OS is Ubuntu 10.04 and Windows 7.
Windows 7 installed on the first disk, first partition. Grub is installed on a second hard disk MBR, and Ubuntu installed on an extended partition on a second hard drive.
When I select Windows 7 on the Grub menu, the HDD lamp lights up briefly and then black screen on the monitor, with the status of the keyboard is still functioning.
Until now (with the default boot from first HDD), I have to press F12 to get into the Grub to run Linux on a second HDD.

================================================
I want to keep the Grub on the second HDD.
I have been using the Startup Manager, Boot Manager and Grub Customizer, and this problem still unsolved. The easiest thing that I can possibly do is to install Grub on first HDD, but I was curious and maybe someone can help.
