I can't immediately see a problem. SCCM is expected to get confused by
wimboot, since it's not a PXE boot and the (emulated) hard disk is no
longer visible once WinPE starts up; this is what causes the "Failed to
find the source drive where WinPE was booted from" and similar messages.
The workaround given on http://ipxe.org/howto/sccm (creating
bootstrap.vbs and winpeshl.ini) should work around this.
It's possible that creating fake registry keys indicating a PXE boot
would work around the later problem that you are seeing. The
bootstrap.vbs script seems to be the obvious place to do this. I don't
know off-hand precisely which keys are required, but it should be viable
to either search online or experiment with a non-wimboot PXE boot of
SCCM to find the answer.
