Windows 7 EFI and FreeBSD 9

[agottem]

Hello -

I'm struggling to get a dual boot setup going. I've installed Windows 7 on its own disk. Windows 7 boots via EFI.

I then installed FreeBSD 9, also on its own disk. I created a GPT partition for this install.

To handle the dual boot, I'm using grub2. The grub2 bootloader is currently installed on a flash drive util I can be sure everything works.

I boot from the flash drive, and can load FreeBSD ok via the normal grub commands. I cannot, however, start windows. After scouring the internet for a while, I've found the commands should look something like:

insmod ntfs
chainloader (hd1,1)/efi/microsoft/boot/bootmgfw.efi

When I do this, however, the chainloader command returns the error: "invalid signature". Is this because grub2 isn't loading via EFI as well?

What's the best way to dual boot Windows 7 and FreeBSD using GPT and EFI?

Thanks!
Andrew

Are you sure that's a valid grub2 entry? The website shows it as a little different: http://www.gnu.org/software/grub/manual/html_node/Chain_002dloading.html

menuentry "Windows" {
insmod chain
insmod ntfs
set root=(hd0,1)
chainloader +1
}
