Dual Installation of EOS -->second installation destroy files of the first installation

General system EndeavourOS installation
1

Hello,
at first: it’s not a problen in grub :wink:

I remove my windows installation and try to install on the second partition (first is efi) EOS, … at this moment all is fine…
But i want to install on the third partition a second EOS (for my DJ Work), when i install the second EOS (i think it’s strange), the installation of the second partition become to be destroyed.
I can start the second Installation,
i mount the device of the first installation to /mnt
and it have only this content:
@ @cache @log

in ‘@’ are the EOS Files, in ‘@cache’ the directories ‘fontconfig, ldconfig, pacman, pkgfile, private, samba, swcatalog’

I used on both systems btrfs,
on an other laptop, where the windows partition still stays, i have no problem with a second EndeavourOS Installation.

Someone know, what’s the problem is?

/dev/nvme0n1p1 ist EFI
/dev/nvme0n1p2 (100GB) is the first EOS Installation root / (now empty) (btrfs)
/dev/nvme0n1p3 (100GB) is the /home of the first installation (btrfs)
/dev/nvme0n1p4 (60Gb) ist the second EOS Installation root / (it works)

Could this problem be solved for example making a new user account for this kind of work? I am not certain that this is the most ideal solution.

If you do not select the partitions from first install to be used install should not interfere.

Could be you used install aside?
Would need help install log to see what happens.

I would second what @Dinomonster said. It doesn’t make sense to keep two EOS installs around for this type of use. A second user with separate settings is the best option.

just tried to replicate… but no issue installing 2 instances with BTRFS both working fine…

IT can make sense to have different OS installed in case setups are very different or specialized… i have some in use too …

but thats the subvolumes of the BTRFS setup nothing wrong with it just reread your text and find out that you may only misinterpret?

Thank you very much. May be haven’t understand the sub-volumes :wink:

But at the second installation, the thing were, that it only detect himself with grub… okay, changing default/grub, running os-prober for the grub configuration, but it changes nothing.
Okay… tried to repair grub with a arch-chroot, but it doesn’t work with the subvolumes, so i can’t reach my first installation.
I tried this more than one, no matter, what’s going wrong :wink:

My workarround:
Partition 1 (1. EOS) one with btrfs, Partition 2 (2. EOS, DJ) with ext4

And all works…may be i do an other try with my usb disk, i don’t understand, that your try to install to EOS’s works… :wink:
But for now i have the solution.

Why to install DJ-Things on his own EOS?

  • i tune it for mixxx (RT and so on)
  • it’s safer, because it run’s only for the music
    (it’s bad, when something fail on a wedding, when i’m the dj there) :wink:

Thank you very much
