 +If the Windows Setup cannot recognize your iSCSI drive be sure that WinPE is recognized your network card. Type "route print" to the WinPE command prompt and look for your network interface. If it is not there, you should load your network card's driver by using the "​loaddrv"​ command of the WinPE. Go to a local or a network folder which has your driver and execute "​loaddrv file.inf"​ to load the driver.

 Solution for this error is quite simple, just add a drive for installation time, if the drive is a Serial-ATA connected then set it to //​Compatibile Mode// not //AHCI// (for Windows 7 this doesn'​t matter, you can leave it as AHCI). If you start windows installer once again you will see an error message only at the physical drive, select iSCSI target and just click next. Solution for this error is quite simple, just add a drive for installation time, if the drive is a Serial-ATA connected then set it to //​Compatibile Mode// not //AHCI// (for Windows 7 this doesn'​t matter, you can leave it as AHCI).

 +XFGolden Begin Edit -> This is totally contradictory to the above. But it worked for me when the above did not.
 +
 +In some cases such as mine using an asus m3n-HT Deluxe motherboard with the latest pheonix/​award bios having Serial ATA mode set to IDE(compatibility mode) caused the Windows 7 Ultimate x86_64 installer to view the the iscsi connected drive as a non-bios boot drive. There are three options in this bios for how Serial ATA drives are handled IDE/​AHCI/​RAID . Once the access mode for Serial ATA drives was set to AHCI the Windows Installer saw the physically attached drive as non-bios bootable and the iSCSI attached drive as a valid install target. On subsequent boots the installer completed and I was presented with a freshly installed Windows 7 desktop served from my SAN.
