I just brought a new lenovo P72. I started it and completed the formalities like login etc in windows and it looks fine. I wanted to install ubuntu 16.04 on it and so while installing I selected the option "erase disk and install ubuntu". This is because I do not use windows so did not want dual booting. Since I had done the same in one new laptop I proceeding with instaling ubuntu. The installaton is successful but I am not able to boot now . Please see the file attached. "Lenovo1" shows the error that I get at the start when I try to install ubuntu from my usb.
If I dont use "erase disk and install ubuntu" and use "something else" instead, I see that the "device for bootloader instalation is "/dev/nvme0n1 unknown (256.1GB)" . I was expecting it to be "Intel ssd**" in place of "uknown". Is it correct. Either way the installation in successful but when I try to restart I see the same error as shown in "Lenovo1.jpg". When I force shutdown it and restart, I just see a black screen with:
/dev/nvme0n1p2: recovering journal
/dev/nvmee0n1p2: clean, 187925/15097856 files, 1942610/60375296 blocks .
and nothing happens. I am basically help with no windows and ubutu not booting. is it a graphics problem. I tried setting "acpi=off" in grub but that doesnt work.
I would really appreciate if anyone could help me with this. Its a new harddrive so I do not need a backup.

Is there any reason why you want to install the old 16.04 LTS release? I would try installing the latest 18.04.1 release first.
The current LTS release has a newer kernel and it might detect the hw properly. Also an oem 18.04 image is certified to boot on the P72.
Otherwise disable "secure boot" in UEFI settings and verify that the USB flash drive boots in UEFI mode.
You might try booting the last 16.04.5 release, but I think the chance to successfully install Ubuntu on this system is to try 18.04.1 LTS or the latest 18.10 non LTS release.

I guess the system is still too new to be fully supported.
How many SSDs are installed? Make sure that you disable any RAID configuration in BIOS/UEFI.
Before installing any OS, wipe the first few MBs of each ssd with dd to overwrite any gpt or even mbr signatures.
Than again try 18.04.1 , not the first 18.04 release, or even better try installing 18.10.
18.04.2 should be released soon according to this release schedule. So you could try one of the current pre-release daily images of 18.04.2. Most likely they still have some bugs...
Otherwise, I would try installing a minimal installation and see if this works and go from there.
If I understand this report of a successful installation, than they installed the linux-oem kernel and not the default kernel line.
I'm not that familiar with Ubuntu, but maybe there is a point in the installation process where you can select which packages/kernels you want to use.

according to this message an Ubuntu derivative named POP! OS works well on the P72.
nomodeset instructs the kernel not to switch console to higher resolutions, avoiding issues with newer gfx cards.
Installing the linux-oem kernel might be possible with the text based debian installer.
Is the system stable if you boot just into text mode (no gui)? Than you can install the kernel with 'apt install kernel-oem'.
But you'll still need to install a newer Nvidia driver to get system fully stable. I guess right now POP!OS might be the way to go.
Did you try one of the daily 18.04.2 pre release images?

I had no issues installing Kubuntu 18.04 and later upgrading to 18.10.
I guess one important point it so switch in the BIOS to discrete graphics (make sure you have a current BIOS version first, older version were bricking the machine!).
The touchpad got a fix in newer kernels.
So as it's brand new hardware 18.10 might really be the best version (and then upgrading till the next LTS comes along and then stick to the LTSes)
