I have a multi-boot setup with Win98, Win2K, WinXP, Win7 and a few Linux distros installed across four hard drives (2 PATA and 2 SATA), and I boot my machine via Grub4Dos from an USB stick so that each of my four drives can boot whatever I might have installed anywhere without my ever having to be dependent upon any single OS (bootloader) in order to boot my machine at all. Then to avoid having to repeat my menu selection made in Grub4Dos during machine startup, I have one Win7 BCD that bypasses its menu and goes directly to Win7, another BCD to do the same for Linux (a Linux menu), and then yet another BCD to bypass the Win7 menu and go directly to XP.
What I think I need in order for that to work in relation to XP from a secondary loader is for Grub4Dos to re-arrange (re-map) my drives prior to sending my system to a drive my BIOS does not know and report as "C:" (in Windows terms). Again, I have three unique BCDs pointed toward a boot.ini for XP in each of their unique partitions, but each of those BCDs still ends up leading back to the boot.ini file at system "C:". Here is something like what I think I need, but I do not think this is complete for setting my third drive as BIOS "root" or whatever before Grub4Dos sends the machine there:
map (hd3) (hd0)
map (hd0) (hd3)
map --hook
uuid ################
