We are finding in Ubuntu Forums that a lot of variation by Computer Vendor and model.
Some work just the way they should and dual boot Windows 8 and Ubuntu without any issue. Some require secure boot and the shim file works to boot Ubuntu. But some seem to be hard coded to only boot /EFI/Microsoft/Boot/bootmgfw.efi. A work around is the rename shim to the Windows efi file and that works. And some just do not seem to work at all. Not sure if user issues with all the new settings in UEFI menus or how UEFI is implemented.
