NUC Install Issues - nvme pcie drive

[Wirezfree]

[size=1em]Hi,[/size]

[size=1em]I started new thread instead of using the other thread.[/size]
[size=1em]I think this is possibly disk related..??[/size]
[size=1em]I booted a live gparted, and prepared partitions in advance. (see below)[/size]

[size=1em]"IMPORTANT" the NUC contains a "Samsung nvme pcie ssd"[/size]
[size=1em]So gparted detected drive O.K, and allowed me to create partitions.[/size]
[size=1em]Linux kernel gives an odd, but normal: /dev/nvme0n1p1[/size]
[size=1em]I decide to install LL2.6 1st and make sure everything works.[/size]
[size=1em]I ran LL2.6 Live boot USB, installed it, and it all ran O.K, no errors.[/size]
[size=1em]On re-boot I get the "grub screen"[/size]

[size=1em]I checked Win7 still booted O.K, and it booted fine.[/size]
[size=1em]Then I re-booted and selected "Linux Lite",[/size]
[size=1em]momentary disk access, then the following: (sorry only have camera phone)[/size]

[size=1em]Couple of observations/notes:[/size]
[size=1em]1. The NUC Bios is set to Legacy & Safeboot "disabled", and the nvme pcie drive is recognised in BIOS[/size]
[size=1em]2. For the Win7 install I needed to install it initially to 2nd drive, add 2 NS hofixes, then "clone" to nvme drive.[/size]
[size=1em]    This is because Win7 does not recognise nvme pcie drives.[/size]
[size=1em]3. I think the disk order is due to the nvme pcie card being plugged direct on Mobo, and 2nd disk is on SATA port[/size]
[size=1em]4. The nvme pcie disk "Model Unknown."..?? and it's sector size 512B/512B vs other disk is 512B/4096B ??[/size]

[size=1em]Googling shows nvme pcie drives appear to be problematic in terms of setting up for Linux Boot[/size]
[size=1em]I got confused, when discussions centred around UEFI & GPT started to be discussed, no mention of "Legacy scenario"..!![/size]
[size=1em]So more research needed, but any comments welcome [/size]
