So notice i am a bit aknoledged with booting dealing with Grub UEFI EFI Dual Boot etc. I followed everything regarding the post above.

I just bought a new Lenovo Thinkpad P15 Gen2 for my daily basis. I needed a dedicated Graphics A3000 upgrade and at least 64 GB of RAM for my Neural Nets and Sysadministration work. Decided the Thinkpad choice because of it`s toughtness and etc.

Altought i`ve been seting my daily drive (Debian/Ubuntu + Windows) I have also my neural nets work that are built over Arch and consecuently Manjaro.

Unfortunetly i`ve been trying to make it boot (actually install Manjaro) on the NVMe and I have the same issue: There is no Partition Available for Install

Followed all the steps deactivated, secureboot (this laptop doesn`t have AHCI) etc etc etc.

And no progress. I am currently really frustrated because this was my final step for working on NN in Arch and really going to other system rather than manjaro is gonna take me a lot of effort. I Saw this Thread and is closed. I don`t know if anyone can contribute to my issue.

Thanks in advance

Hello @navigator :wink:

So your problem is that the UEFI decides to remove the EFI Entry of manjaro in a dualboot?

Windows and Manjaro, do both share one efi partition? Don’t do so, 2 separate efi partition for each OS. In the past I had also issues with that because of Windows and UEFI which prefers Windows.

Weird, because actually as i explained I already have an UBUNTU efi for that, so my disk looks like this:

Device Start End Sectors Size Type
/dev/nvme0n1p1 2048 206847 204800 100M EFI System
/dev/nvme0n1p2 206848 239615 32768 16M Microsoft reserved
/dev/nvme0n1p3 239616 655362047 655122432 312,4G Microsoft basic data
/dev/nvme0n1p4 655362048 3155363839 2500001792 1,2T Linux filesystem
/dev/nvme0n1p5 3155363840 3157317631 1953792 954M Microsoft basic data

Not sure if my issue was your issue, but there is a know bug with the live iso installer and nvme drives. You have to boot the live usb in open source mode without prop drivers, than start gparted (not sure if just starting is enough, i actually created the partition there), close gparted and then start the installer.

Somehow starting installer after gparted make it see the nvme.
