Ok, for this you can take winpe3. This is smaller (~140MB), but boots
slower. Additionally you have to inject iscsi-funcionality, which isnt
on winpe3 by default. At WinPE4 there is iscsi and powershell built in
by default. Btw, winpe4 is able to install win7/2008r2, too.

Yep. Dont forget to include iscsi in your winpe3! Maybe you can get a
problem with the dvd-filesystem. I wasnt able to use a winxp-cd as
iscsi-disk directly because of the lack of iso9660-support of my
winpe-iscsi-driver, but maybe you have more luck with win8-dvd.
Otherwise you can try bulding a virtual ntfs device and put the win8-dvd
files onto it.

Be sure that the c: drive exists and the dvd-drive is _after_ your
existing dvd-drive (if there exists one).

Good luck!
