EasyBCD 2.2 can't be prevented from picking (incorrect) drive letter for Linux boot

$

I have Win7 on one drive, WinXP on another (not even attempting to boot that yet), and Ubuntu 12.04 on a 3rd.

"Add New Entry" selecting Linux/BSD and just about any type (though Grub2 would be the correct one) will fail. The reason is that, even though I can select "Partition 1 (Linux - 149GiB)" under the correct Drive in the Drive menu, this is then ignored, and no matter what I do, the actual boot menu entry created is always:

Code:

Real-mode Boot Sector
---------------------
identifier              {...}
device                  partition=E:
path                    \NST\AutoNeoGrub0.mbr
description            NeoSmart Linux

Needless to say, "E:" is not the device/partition I selected, nor can I prevent EasyBCD from selecting it for me. In this case, E: is the WinXP partition (for which I'm not even trying to add a menu item yet). The Linux partition has no drive letter, for obvious reasons.

Under "Advanced Settings" the Drive options include all the letter drives, and something called "BOOT" - which, when selected, results in a failed boot.

The system boots fine with Grub 2. However, if Windows does not control the boot sector, it cannot back itself up. :(

Is there any way to get EasyBCD to boot the desired partition?

Addendum

Hmm... experimenting further, I have something working. When I rearrange the order in which the drives are connected to the motherboard, putting the Win7 drive first, and the Linux drive second, attempting to add a Linux boot menu entry now results in device being "partition=C:" - which is also incorrect, yet, selecting it at boot time results in a successful transition to grub 2.

Also, in this configuration, Windows 7 will back itself up.

Is the selection of the boot drive by Windows letter a limitation of Win7/BCD? Because it's definitely the wrong way to select a drive and partition within a bootloader.
