Hi there, I recently bought an xps 13 9343 2015 edition. I swapped the toshiba default ssd with one of the samsung sm951 m.2 ahci drives. Thanks to the BIOS updates, windows 8.1 works on it but I can get Windows 7 to install on it.
When I boot from usb (legacy BIOS with secure boot OFF) it brings up windows 7 install but when it lists the partitions, I'm not allowed to install on the primary. I click show details and it says it can't install because it's of the GPT partition style.
Can someone help me understand what this means and let me know if it's possible or not to put Win 7 on these drives? I would truly love to run Win 7 but I'm stumped. Any help is greatly appreciated, thanks.
