Hey I've downloaded minimalgui iso but can't run it on laptop with secure boot enabled, Debian works fine with secure boot, was wondering is any of Sparky isos are "secure boot ready".
Yes, you can!
Disable temporary the Secure Boot option in BIOS.
After the installation, reboot into Bios, enable Secure Boot, and the computer will boot Sparky without problems.
Welcome for both of us!
