Still installing EndeavorOS

Hello hello again. Thanks for the responses yesterday. I’m trying to only boot EndeavourOS (KDE plasma), making the switch from Ubuntu. I have a 2tb HDD and 500gb SSD, I want to install EOS (systemd boot) onto my SSD which currently has Ubuntu installed.

When I try to erase disk I get this error https://termbin.com/nh3c
When I try to replace partition the next button isn’t highlighted and won’t let me press it.

My hard drive still has information from my windows boot which was about 2 OS’ ago (I didn’t mount it when going to ubuntu because I had too many I’ll do it tommorows). This maybe could be causing the issue?

It seems like my only option is to manually partition my ssd but I’m not sure if I do the manual partition on the one showing as ubuntu or nvme0n1. I’m assuming it would be nvme0n1 because it’s bigger.

I’ve looked through https://discovery.endeavouros.com/installation/live-iso-tricks-tips/2021/03/ and taken the steps shown but I just wanted to double check if I needed to make any other partitions/ take any other steps so I don’t break my pc.

Step 1. New partition > GPT > Create > Size 2048 MiB > fat32 > /efi > flagged boot.

Step 2. Free space > Create > Size (left untouched, 455813 MiB) > ext4 > /

It doesn’t say to flag step 2 or what it’s used for. I’m assuming this would just be empty space. Would I be ready to install from there?

For now I just want to get into EOS so I can start fiddling around with it without everything I’ve done disappearing once I shut my PC down (curse live mode).

I’m happy to wipe both my drives, I’ve backed up everything I’d need onto a separate USB drive.

On a separate note: I’d like to learn how to manually partition/mount drives because I have a couple 1-2tb hdds laying around that I’d like to try adding to my PC. If I could get some recommendations for where to look into this a bit more I’d appreciate it greatly.

Sorry if this is too cluttered, I tried to not miss anything out just in case

On this screen check replace a partition next you have to click on the blue bar on the bottom and a option to create a efi partition should pop up. If for some reason this doesn’t work you can create a partition using Gparted on the live installer.

Also make sure you did not mount the disk before running the installer. When it’s mounted in the live environment you get less options as well.

Issue could be caused by the LVM ?
In case calamares (installer) tries to reuse the LVM somehow was it mounted on the livesession before starting installer?

the /dev/ubuntu-vg is housing on /dev/nvme0n1p3 ?

And only shown as a drive as of the LVM ?
In reality you have 2 Harddrives installed i think?

The way to go would be to remove the partions manually before installing so that the LVM is not getting reused.. only in case you want to use WDC /dev/nvme0n1 drive for replacing it with EndeavourOS.
Open partitionmananger and create new partition table (gpt) reboot and try again. Make sure System boots in EFI mode too (terminal a like boot menu and use boot entry for USB starting with UEFI) or check on the livesession ina terminal run: efibootmgr will shhow boot entries if EFI if not shows an error.

I use manual partitioning (with grub, tho). Often, if you reinitialize the target disk first, using gparted to create a new gpt-based partition, a number of options open up that were not previously there in Calamares. Might be worth a try, but the experts here probably have more to offer than I.

exactly this.. a clean drive is always the best .. in most cases it does not have issues to detect partitions properly . but lvm stuff is not really fully implemented

Thank you very much everyone!!! I wiped my drives with gparted and it worked with no problems! Thank you so much, I’m sure I’ll be back with stupider questions.
