System can't find installer for Titan Neo?

General system EndeavourOS installation
1

Some context:

I tried iso’s from both the torrent system (sorry about the terminology, I’m unfamiliar with torrenting) and a local mirror.

I used the dd command to load the iso onto a usb stick. I know that the usb is functional because I used it to install Omarchy previously on this machine.

When I try to boot into the usb, a grub terminal pops up instead of the installer. I have no idea how to proceed from there. I have tried different ports on my computer, I have tried an iso from a different source (the local mirror) and all permutations have the same outcome.

Secure boot isn’t on, I’ve installed different arch variants on this computer before (Omarchy, EOS Ganymede Neo).

I have no idea how to proceed from here, any help would be much appreciated.

It sounds like you aren’t actually booting off the ISO?

Did you try disabling CSM in the BIOS temporarily?

According to Google, the way to disable CSM on my computer (a Lenovo Thinkpad) is to set the boot mode to UEFI only.

I changed that setting (saved before exiting), and tried once again to boot into the installer, only to be greeted by the grub terminal once again…

Just a note for anyone else facing a similar issue, to turn of CSM, you have to change the boot mode to UEFI only AND change the dropdown right under it to “No”.

The ISO doesn’t use grub. So if you are seeing grub, you are booting something else other than the ISO.

Either Secure boot is still on somehow and it is going to the next element in boot or you are booting off a disk other than the ISO.

For what it is worth I installed over the weekend both online as well as offline without any problem using the ISO, and I know for sure it does not use the Grub bootloader (but systemd boot). Maybe something went wrong when using the dd command ? How do you boot the USB stick do you use boot override (F11 or F12 or whatever your system support) or do you boot using the BIOS boot menu , and are you sure you picked the right option ?

I realized what the issue was.

When plugged in, the usb stick mounts onto /dev/sda. I kept writing the ISO to the /dev/sda1 partition of the drive instead of the whole drive itself. I assume the /dev/sda2 contained grub (possibly from the last Omarchy install?) and since I was leaving that intact, I kept facing a grub terminal again and again.

This time, I rewrote the /dev/sda instead of /dev/sda1 and I was able to get the live session working properly.

Note: I used caligula instead of the dd command to write the ISO this time, but I don’t think that is what made the difference.

this was the issue for sure.
