I just received ( June 22, 2016 ) my AW17R3 4K Display with 8GB video, 32GB RAM, 256/1TB with Win10 Pro. BEAUTIFUL screen!! I ordered and installed a 512GB M2 card so I could install Win7 Ultimate on it but all attempts so far have failed. Error messages that there is no space when using an external DVD. Tried a USB stick, same error. Copied DVD on the blank E: (512 GB) to install, and it chokes at drivers. Downloaded all drivers from Dell site, still no joy. Has anyone else installed Win7 onto a AW17R3 that came with Win 10? Thanks!
Check settings in the Bios (F2). Make sure SATA MODE: is on AHCI and BOOT MODE/BOOT LIST OPTION: on EUFI.
