I've installed Fedora 17 and Windows 7 on two different hard disks as a dual-boot system. The default boot loader is GRUB 2 maintained and configured in Fedora 17. When I startup and choose "Windows 7 bootloader (on /dev/sda1)" in GRUB 2, Windows 7 boot loader will appear, with only Windows 7 as the only choice and also the default operating system, with a 30 second waiting time if no input is detected. I'm trying to see if it is possible to remove this 30-second waiting time. I've tried to follow the instructions on the Web by configuring default operating system in the control panel but seems there is something wrong with it. I've also tried to use "bcdedit enum /all" but still receives error prompts. Update: Added my boot tab screen in msconfig.
