Less of an EOS question, more of a general systemd question, I guess.

I’d like to install CachyOS alongside EOS. In all my years with Linux and distro-hopping, I’ve never done 2 Linux distros side-by-side. The last time I dual-booted anything was with Windows 8.1 and Debian years ago. And that was the GRUB way.

EOS is already on my SSD in its default configuration… systemd. So, if I install CachyOS “alongside” EOS, and stay with systemd, upon reboot, I should see a choice for both OS’s? Or is there something I need to do beforehand?

Sorry for the noob-like question.

Yes, as long as Cachy and EOS share the same EFI partition and both are using systemd-boot, everything will work automatically.

WIN/Linux a failure always. Linux/Linux always good. Here’s how I do it

1. in live iso use gparted to shrink Endeavour filesystem. your call. -200GB? can you spare it?

2. stay in gparted and format the new cachy partion GPT (unless Cachy has different demands?

3. if using Cachy ISO for all this work, then close gparted and install Cachy into that partion. Let Cachy installer do the rest.

4. I always use two different sysd bootloaders (I’ve never had any distro share a boot but that’s just me) and F12 when booting so I can pick what…but I don’t know what makes any install go to Cachy or Endeavour first. so happy with F12 boots.

4.5: always works for me. PS I never mess around with no grub if I have an sysd bootloader with the original distro.

two cents

GPT is not a format (like ext4, btrfs etc.) and not at partition level.

GPT is a partiton table at disk level.

Making the disk GPT (creating a new partition table) would effectively wipe the whole disk.

Here’s what I get after install of CachyOS. Default systemd insall from start to finish. Shrunk partition by half and installed.

Have I borked something?

I said the partition. and anyway you are right it would all be gpt to begin with. I mean EXT4. My bad.

Thanks for catching that,

PS—to Uncle I like to do as much for the bootloader as I can before I use one. I never make them do all the work. I like to prep it before install.

Just the typical screen I always get to choose what to boot. Usually shows my EOS kernels.

Did you check your boot options? There may be other boot option maybe eos that will have cachyos in the menu.

Is that from the live usb or from Cachy?

Can you boot your Cachy? If you can, post:

```auto
sudo parted -l

lsblk -f

efibootmgr 

cat /etc/fstab

```

Yes, I can boot Cachy just fine. There seems to be no way to get to EOS.

as i said I don’t know which bootloader picks which OS to default to first. That’s why 2 bootloaders for me and boot F12 if you can live with F12.

But you got one bootloader in pic so I’m going stand back having never shared a bootloader before so out of my depth.

good luck this will be something simple

Did cachyos format your ESP or erase the existing entries?

Create an arch-chroot for EOS and run `reinstall-kernels`

Yeah, with systemd-boot it is pointless to have 2 bootloaders. It is just extra complexity for no real value.

Exactly! I was thinking that as well!

@UncleSpellbinder

What is the output of:` ls -al /boot` ?

This shows 84% of the ESP being used. OP seems to have installed 2 kernels judging by the boot screen screenshot. Is that normal if they have formatted the partition? I mean the used space?

No, but it seems pretty unlikely that they have if 84% of 2GiB is used.

Could it be that EOS’ loader entries have gone missing somehow? Just trying to wrap my head around the issue.
