Windows Setup fails when installing to iSCSI/LUN without proper boot support

The problem: Installing Windows Server to network storage (iSCSI/SAN LUN) fails or does not boot because boot-from-SAN prerequisites are not met.

Symptoms: Setup sees LUN but boot fails after install; boot device not found; installation errors around storage/boot.

Likely cause: Firmware/adapter not configured for boot-from-SAN, missing NIC/HBA boot support, or incorrect multipath/storage drivers.
