Just a heads up, a new variable is required on version 0.23 for an APP_SECRET. I added this to my template and updated and but seem to be stuck at the login screen despite a correct user name/password. Ended up reverting back to 0.22. Fix appears to be in the works: https://github.com/nicotsx/zerobyte/issues/417
Just wanted to log that I was having similar issues on my Lenovo Thinkcentre M90q. Was unable to boot from USB using the UnRAID USB Creator tool with a brand new Transcend JetFlash 32GB drive. I have the same flash drive on my primary server. Tried a bunch of BIOS settings, confirmed that Secure Boot is disabled. The same flash drive was able to boot up other Linux distros created using Balena. What ended up working for me was formatting my drive using Rufus - FreeDOS in FAT32 and doing the manual installation process. Did not need to make the drive bootable in my case.
