I just got my Dell XPS 9550 laptop, then I installed fresh Windows 10 Pro x64 on it, shrinked the volume for Ubuntu, and tried installing Ubuntu 16.04 via USB stick from ISO.
I did the install alongside Windows option, clicked next and it installs more than halfway, then it error out with this:
Unable to install GRUB in /dev/nvme.
Executing 'grub-install /dev/nvme failed.
This is a fatal error.
I have the following settings in BIOS: Legacy boot, AHCI, Secure Boot off.
Laptop configuration: i7-6700HQ, 16GB DDR4, 512GB Samsung P951 NVMe SSD, FHD screen.
Any help would be greatly appreciated. Thank you!
