I'm facing some issue with detecting the SSD nVME disk on Ubuntu 18.04 while installation. But 20.04 works perfectly without any issues.
I have tried with the latest ISO Ubuntu 18.04.5 and BIOS updated to latest. Then changed the SATA to AHCI mode. still this is not detected.
Disk -> PM981a NVMe SAMSUNG 2048GB Model -> Dell Precision Tower X-series 5820
Note:- this is not a dual boot. It's a single installation only
Thanks
We 're trying to install ubuntu 18.04 on Dell Precsion 5820 USB-C type model after the install splash screen it goes to blank screen . we added below directives
In the grub "Install Ubuntu" prompt.
( Press 'e' ) Remove "quiet splash"
Add "nomodeset acpi=off"
Then hit "Ctrl + x "
Still no luck. Please let me know how to proceed from here. We already tried keeping acpi / nomodeset alone. Still no luck
Ubuntu 20.04 LTS no issues, it loaded smoothly.
In our environment, we having old versions of 5820 which worked before acpi/nomodeset
Issue:- Booting into recovery mode, after post installation
Tried nomodeset parameters added in grub, able to install and post installation of NVIDIA-440 , machine booting in recovery mode.
Note:- Ubuntu 20.04 LTS worked without any issues.

Below is the journal logs, for the failure of machine boots into emergency mode. For some reasons, while unpacking the initramfs, it's unable to mount the EFI partition and dropping into emergency mode. And it's points bad superblock
Might-be this is a bug in the 18.04. At the same time 20.04 worked without any issues.

We are able to boot even after passing nomodeset in GRUB.
This is a freshly installed machine, and tried with different kernels while switching from higher to lower. In all the case, same result.
This machine consist of two drives SSD and HDD. I suspect it might be caused issue with hardware dependency?
