Hello!

I'm trying to install W2k8 r2 direcrty on DELL MD3000i iSCSI disk and use windows server 2008 diskless boot. I use Intel Ethernet adapters and Intel iSCSI remote boot technology. According to Intel last PROINFO v18.5
Windows Server* 2008 (and beyond) natively supports OS installation to an iSCSI target without a local disk and also natively supports OS iSCSI boot.

Well, OK. Server starts and NIC succesfully maps to selected LUN (4 or 5 in my case)
When I selected an iSCSI LUN on the "Where do you want to install Windows?" screen I've got an ERROR

Windows cannot be installed on this disk. This computer's hardware may not support booting to this disk, ensure that the disk's controller is enabled in computer's Bios menu

I used 2 different servers with 2 different NICs and got identical results. One is Supermicro with X8DTL-iF motherboard with 2 Intel 82574L LOM (iSCSI boot enabled). Second is Intel SR1530 with additional Intel CT Desktop Connection (updated with iSCSI v2.8.x boot firmaware).

All this stuff are connected via CISCO Catalyst 3560G-24TS switch through dedicated static VLAN. Network connectivity is OK because DELL MD3000i works as common storage for SQL Server 2008 cluster with 2 nodes.

For iSCSI remote boot I use free LUN (number 4 or 5).

Any questions for detailed info accepted.

Any help, tips, links, suggestions will be highly apreciated.

Thanks for your time.
