Hi Thomas (et al.),

thanks. I just discovered a work-around for my issue with the UEFI BIOS looking at
  http://www.syslinux.org/wiki/index.php/SYSLINUX#LOCALBOOT_type

Basically it suggests to replace the stanca
  LOCALBOOT 0
by
  LOCALBOOT -1
in the appropriate PXELINUX menu. This causes the BIOS (and also the UEFI BIOS of the ASUS motherboard we have) to accept the failure of the PXE boot and move on to the next entry in the boot order. I tested it also with one of our older PCs without UEFI BIOS for which it worked as well.

This trick saves me from spending some time on debugging a combination of pxelinux and syslinux boot menus. (Sorry, no recipe for that.)

Cheers,

w.w.

P.S.: Here are the contents of my localboot.inc snippet:

# localboot.inc
label local
MENU LABEL BOOT FROM ^LOCAL HARDDISK
# request booting from local disk -- has issue with UEFI-BIOS
## LOCALBOOT 0
# set LOCALBOOT to -1 to signal failure instead
LOCALBOOT -1

IMO this seems to be a general UEFI problem^Wfeature. All my install
clients still use the legacy BIOS mode. But I know new computers may
not support the legacy mode. I guess syslinux is the best source for
fixing this problem.
I would be happy if you could post your solution here.
