Dual booting VHD with Win7 - winload.exe error

Hello,

I created a Windows 10(x64) To Go VHD and it boots fine on my USB and HDD but won't boot on my SSD that has Win7x64 installed. I get the error about winload.exe not passing integrity check, or a disk read error. The strange thing is that it will boot from the boot entry on my other HDD. I just can't get it to boot from bootmgr on the drive it's actually on. (So the VHD file runs fine.)

When I boot from the Windows 7 partition, and choose Win10-to-go, I get the winload.exe error. When I mark the partition with the VHD as active and boot to it I get a disk read error. When I boot from a bootmgr partition on another HDD with WinToGo.vhd in the BCD it boots fine.

All my disks are MBR NT 6.x. All partitions boot with bootmgr. I have no GPT disks and my ASUS UEFI Bios boots in legacy mode. I have no separate boot partitions. Each partition has it's own bootmgr and BCD. Win7x64 is on first SSD partition, Win10 to go VHD is on second partition.

What am I doing wrong on the SSD?

Update: I tried booting with VHD mounted (shown in attached image as drive F) and unmounted. No difference.
