If anyone needs or have to install windows 7 on DELL brand laptops for any reason, I highly recommend you to wait until you confirm it can be done.

I have Dell XPS/Precision 11 and 13, the problem is the Windows 7 have difficulty to boot from UEFI, and you will stuck because AHCI is not supported by these DELL's BIOS.

What does any of that have to do with Ubuntu shipped Dell XPS 13s?

I bought some XPS 13 with ubuntu installed. By the time I need windows 7 on the field, but I found out it is not possible because you will stuck at "AHCI not competable" BSoD no matter what ever you do.

I bet not everyone realized it is not possible(with my limited knowledge) to install Windows 7 on DELL laptops with UEFI bios.

Put Windows 7 in a VM on the Linux partition.

I booted Linux in UEFI and Legacy mode on my XPS 13 9350, it works fine.

AHCI is not related to UEFI. It's a SATA disk controller mode and these laptops ship with new NVMe disks which use PCIe bus instead of SATA.
