I'm currently testing this boot.iso from the secureboot directory: 362807296 Jun 21 00:59 /tmp/boot.iso My only secure boot capable computer is a lowly Acer Aspire XC-105 desktop computer. The settings are currently set like this: System Boot State: User Secure Boot Mode State: Enabled Secure Boot: [Enabled] Secure Boot Mode: [Standard] Default Key Provisioning: [Enabled] When I enter the boot menu with F12 and select my USB stick, I get a nasty "Invalid signature detected. Check Secure Boot Policy in Setup". RHEL7rc1 doesn't boot with these settings either. Disabling Secure Boot lets me boot from the USB stick, and the media check passes. Please advice. I also made test installs in UEFI mode on two non-secure boot capable systems from that media as a sanity check. The systems were a VirtualBox VM and a Dell R320. These installs worked fine, but as mentioned, without secure boot.
