SOLVED: The boot order has to be organized manually in the BIOS. In my case, hitting F12 to select the USB stick as temporary boot medium wasn't enough.
Was wondering if someone has had the same problem / might know a fix:
I've been trying to install Ubuntu on a new hard drive (the current one runs Windows 11 Pro and I'd like to have a second OS on my machine). Once I flashed Ubuntu (24.01, AMD 64) on a USB stick (via balenaEtcher) I tried to boot from the USB device. If I do so, I receive the message reading "error: file "/root/" not found. After that the screen appears where I can choose to try to install Ubuntu, however, it is frozen / unresponsive.
Some additional info:
- The hardware I'm using is a rather new E14 Gen 6 Thinkpad (Intel Ultra 7 155H).
- I've installed a 1TB hard drive and formated it before use
- Disabled fast boot (set to diagnostics instead), secure boot and security chip
- Used two different USB sticks and changed USB port
- Although I'd like to install Ubuntu, I tried POP.os, Ubuntu Cinnamon, Mint, just to see if the iso/distro might be the source of error
- Also tried Ventoy (exFAT MBR) and Rufus
- Enabled Allow Microsoft 3rd party UEFI CA
Thanks for your suggestions
