SOLVED [git r4682] ipxe 'Boot from hard disk' option boots to memtes86 instead
‘Boot from hard disk’ is the first (and default) option in the ipxe menu, but on my setup it is currently booting into memtest. This makes it impossible to boot to the OS, as the hosts simply boot back into memtest after being reset.
The current workaround I am using is to hide the menus; then the menu gets skipped (unless I hit ESC) and the computer continues to boot to the OS.
I updated to the latest git version of FOG today, and whatever had been causing this issue is now gone. This thread can be marked as solved.
