I have an Acer Veriton M4640G with pre-installed Windows 7 in UEFI mode and
openSUSE 13.2 32 bit installed in BIOS-legacy mode because installation DVD was
not bootable in UEFI mode. "Secure Boot" is disabled in BIOS.
I installed in UEFI mode Leap 42.2, rebooting with inserted Leap DVD-> Boot
from Hard Disk shows "error: no such device: /efi/boot/fallback.efi".
Rebooting without DVD starts Windows 7.
Leap can be started by DVD->"Boot Linux System". I installed boot loader again
by Yast. "efibootmgr -v" shows

(9) is openSUSE 13.2 /,(11) Leap 42.2 /, (12) Leap 42.2 /home
The installation of openSUSE 13.2 32 bit probably set the MBR.
