So we're asking that anyone who has a machine with a UEFI firmware on which they can safely do a disposable test install - to a spare disk or partition or whatever - try and do a *native UEFI* install of F19 Alpha RC2 (if writing to a USB stick with livecd-iso-to-disk, remember to pass --efi to make a UEFI bootable stick):<br>

> and see if you get a successful install. Bear in mind that there are obviously other bugs you might run into as this is an Alpha build - if you run into anything else by all means report it separately, but what we're principally interested in is, if you make it to bootloader installation (one of the last things done in the install process), does it succeed, or do you get an error? And if it succeeds, does the installed system boot - at least as far as grub?<br>

<p dir="ltr">I have such a machine. What kind of media should I test - usb, disc, pxe, all of the above? Should I report results here? </p>
