Description

This test validates booting from a efidisk.img on a system capable of supporting Features/EFI.


How to test

  1. From an already installed system, insert a USB key (with enough capacity to hold the efidisk.img image)
  2. Locate the device entry for your USB key (for tips, see http://docs.fedoraproject.org/en-US/Fedora/30/html/Installation_Guide/Making_USB_Media-UNIX_Linux.html)
  3. Write the efidisk.img to your USB media by typing:
    dd if=/path/to/efidisk.img of=/dev/sdd
  4. Insert removable media into your test system
  5. Reboot the test system. If offered, but sure to select the USB device as your boot device

Expected Results

  1. The system should boot into the installer without error
