Hi Ansgar,

I recently had to solve the same issue. You need to use the gPXE 
commandline with the following:

   dhcp net0
   set keep-san 1
   sanboot iscsi:<iscsi server ip>::<iscsi port>:<iscsi lun>:<iscsi 
target id>

Then, depending on whether you are installing Windows from a DVD or from 
a WinPE image through tftp you would either run:

   exit

so that gPXE hands things back over to the BIOS, to boot from DVD or:

   chain tftp://<server ip>/Boot/startrom.n12

so that gPXE starts the WinPE image ftom tftp.

More info on the gPXE commandline can be found here [1].
Also, there's some good documentation on installing Windows to an iSCSI 
target in the gPXE howto guides [2].
Finally, I found the following page helpful if you get some errors [3]. 
If you created your iSCSI using tgtadm on Linux, be mindful that you 
probably have to specify an actual LUN parameter (rather than just ::::) 
in your isci address.
