How to get dual booting to work when using burg and two hard drives?

Question

I have arch linux on one 250GB hard drive and windows 7 on another. I can boot into ArchLinux just fine, and I can boot into windows if I unplug the hard drive with Arch. But when I boot with both plugged in, I get the option of either linux or windows and when I choose windows I nothing happens. Now I know the problem is that the Windows hard drive needs to be tricked into thinking it is the primary hard drive. But I don't know how to do this using burg.

So what do i need to edit to make this happen?

It looks like you need to do a disk map just like you would in grub to swap drives. Windows gets confused when it normally boots up as the primary drive and then suddenly it's number two but still being booted too. In grub you would do this:

title Windows
    rootnoverify (hd1,0)
    map (hd0) (hd1)
    map (hd1) (hd0)
    chainloader +1

It looks like there is a similar command in burg, but the syntax is different. Perhaps something like this:

 map (hd1,1)/disk.dsk (hd0)

...but that is untested and found on a series of posts in Chinese on equivalent grub configurations. However in burg there is also drivemap which may be what you need. Try adding this to your configuration.

drivemap -s (hd1) ${root}
ntldr /ntldr
