installer could not put a boot reference on any 'device' chosen from those on on uefi gpt drive

[Stevo]

On a win 7 home premium Asus N56vm laptop - used partition wizard mini tool to make an ext4 partition and some space after the standard uefi windows partitions.

put a \ mount point in ext4 partition made an ext2 home partition made a swap of 10 GB
using a usb2 16 GB sandisk pendrive with a bootable 13.04 ubuntu live.
persistance enabled with boot repair downloaded and installed to it.

installer seemed to do it all and then showed a message that it could not place the boot

Uefi machines are some years old now and win 7 isn't exactly new. There is no secure boot issue as in win 8 so why the installer troubles? What a shambles!
