I replaced the original Chinese language Win10 on the SATA SSD on my Notebook Air 12.5 with Ubuntu Linux 16.10 with no issues and also installed an English language copy of Win10 from a USB onto a 128GB PCIE SSD (Toshiba ) that I put into the empty M2 slot.
The Win10 on the PCIE SSD runs OK, but it boots _very_ slowly (taking several minutes to start up) and also occasionally fails to shut down completely (the screen blanks but the power light stays on). The Ubuntu on the STA SSD boots instantaneously and shuts down happily too.
The BIOS is set to UEFI and the first boot disk is the Ubuntu SATA installation. Win10 boots off an entry in the Linux grub bootloader menu. The delay is at the start of the Win10 bootloader splash where the dots are circling. The Win10 installation is fully updated and thinks it has all the correct chipset drivers etc.
Has anyone else seen similar (slowww….. Win10 boot) behaviour off the PCIE slot?
