Posted: 29 Sep 2010 12:19 PM PDT

Hi,Guys. I have 3 hdd. On first I install windows 7 (main operating system), now on second hdd i install fedora 13. As i install Fedora 13 for learning and educational purpose, so I don't disturb mbr on first hdd and install grub on second hdd. Now it shows Windows 7 and Fedora in boot menu but boot only Fedora from there. When I select Windows 7 , screen goes black and system restart. When I need to boot in Windows I need to change boot option and boot from hdd1 and when I need to boot in Fedora then choose hdd2.

But I don't want to do this again and again. I tried many thing but all are failed. I do too much googling and read blogs and forum, but not got any solution. Please help me, is there is any way to sort out this problem.
