iscsi problem

[gafgafker]

Hi all.
I have a problem with iscsi os boot. Could you help noob with this?
What I do:
1) I install StarWind Virtual SAN with 1 target and 1 attached virtual visk to it on iscsi host.
2) I install win8 on local hard drive on client.
3) I make a clone win8 disk from step 2 by Macrium Reflect to iscsi target
4) Boot from pxe on client, recieve ip, mask, gateway from dhcp (win2008) and recieve undionly.ipxe, recieve network settings again and try to boot iscsi
5) IPXE shows that iscsi drive is attached and booted from it
6) Same shows VirtualSan for little time and after 30-60 seconds of booting iscsi client disconnets and system get blue screen with 0xc00000e9 error

I tried to install win directly by ipxe manual (this and this), but iscsi disc isn't available. Add network drivers by this guide and manually and nothing again.
