Hi,
I have exactly the same problem as MichelT but with a Lenovo ThinkPad S230u with Secure Boot enabled. Grub starts Ubuntu 12.10 without problems, but Windows 8 doesn't and can be booted via F12 and the UEFI's Boot Order Menu only. As a temporary workaround this is ok but a proper fix by Ubuntu would be welcome.
Regards
Andreas
