ipxe failover to USB not working

[robinsmidsrod]

If you want to install Windows onto an iSCSI volume you need to boot in legacy bios mode (sanboot/sanhook not yet supported on UEFI) and you need to follow the how-to at http://ipxe.org/howto/winpe which explains. You need to put your windows installer files on a network share (samba or windows file sharing). I could of course also load these files via USB after having booted up WinPE via wimboot, but what is the fun in that?
