Install grub in OMV3 with UEFI and NVME- SSD

Hello guys,

Recently, I discovered OMV and I want to install OMV3 on my NAS-machine. Unfortunately, I'm running in a few problems during installation.
Could you help me, please?

Facts:
1. Installation from bootable usb stick to nvme-SSD (http://www.intel.com/content/w…e-drives-600p-series.html)
2. Unable to install GRUB
3. Tried to unplug usb-stick and execute commands in shell as described here: http://wiki.openmediavault.org/index.php?title=Installation
4. Tried to install grub with backport kernel and grub-efi as described here: http://www.poweredbyjeff.com/2…750-SSD-in-Debian-Jessie/
5. Tried to install grub as described here: https://wiki.debian.org/Instal…04thGen%20PCIe_SSD/jessie

Nothing worked and I'm running out of ideas.

Thanks!

Thanks for your quick reply.
Because I've all SATA ports occupied for data disks, I thought it would be a nice solution to install the OS on a nvme-ssd.
Do you think it's a better solution to install it on a usb-stick? How can I find out if my USB stick are using static wear leveling? I've 4GB RAM.

Ok, thanks.
Then I'm going to the option with the usb stick.
