Hi, It may be something to do with disk geometry. Create a new blank freedos image on your iscsi target then try putting in a bootable freedos install cd and boot from a bootable gpxe usb key using this gpxe script:
#!gpxe dhcp net0 set keep-san 1 sanboot iscsi:192.168.52.60::::iqn.2010-12.hu.mavrt.bbf.fc:fdos-disk What happens here is your pc will boot from usb with gpxe on it, gpxe will try to boot from your empty iscsi disk but it cannot because it is empty and then it will fallback to booting from your cd. Your empty iscsi disk will be seen by freedos as a new blank hard drive and will format it properly when installing to it. The instructions are similar to the installation instructions for windows 2k8: http://etherboot.org/wiki/sanboot/win2k8_iscsi_install br, Quinn On Fri, Jan 13, 2012 at 12:14 PM, Ruzsinszky Attila < ruzsinszky.att...@gmail.com> wrote: > Hi, > > I want to test, setup, learn, use a virtual environment. > > I've got a very simple scenario.
