Your problem is that Win7 setup refuses to install Win7 onto any disk that
is not a bios disk. If your PE does not see the the iscsi disk right 
away installation
will not work. Attaching the disk manually will not help you.

You probably need to add something like
set keep-san 1
to your ipxe script. This way ipxe leaves behind an iBFT entry that makes PE
attach to the disk on its own, automatically. We do Win7 install to iscsi
routinely and I learned this the hard way. We still use an oldish gpxe I 
hacked, but the keep-san setting should work the same with ipxe as it does
with gpxe.

Best regards,
