iPXE -- Windows 8.1 installation (fail)

I've attempted to run Windows 8.1 installation in diskless test computer which did fail.

Installation progress:

1. PXE requests DHCP server
2. DHCP server replies with undionly.kpxe
3. iPXE takes control of boot process
4. iPXE calls for http://server/winpe/boot.ipxe script
5. boot.ipxe script sets username/password
6. boot.ipxe sanhook iSCSI driver as 0x80
7. boot.ipxe initiates wimboot
8. computer boots WinPE
9. from WinPE a samba drive mounted as I:
10. cd win10/amd64
11. setup
12. standard Windows 8.1 installation
13. installation reaches "updates" stage
13. installation gives warning that it detected an error and can not continue

iPXE boot.ipxe script


set username [your iSCSI username]
set password [your iSCSI password]

set initiator-iqn


cpuid --ext 29 && set arch amd64 || set arch x86
kernel wimboot
initrd ${arch}/media/Boot/BCD           BCD
initrd ${arch}/media/Boot/boot.sdi      boot.sdi
initrd ${arch}/media/sources/boot.wim   boot.wim

Does anybody had a better luck with Windows 8.1 installation in similar setup?
How far did your installation progressed?

RE: iPXE -- Windows 8.1 installation (fail)
I seem to recall that this "updates" stage is where it needs the network and it is not operational. I recall that the Windows 10 RTM release had the same issue, but Windows 10 r1609 (anniversary update) didn't have that issue. Are you sure you're using the latest install media for Windows 8.1? If you type Shift-F10 (not sure if that is available at this stage of the installer) and look at the installation logs in the windows directory you might find out the reason for your errors.
