Last week I did a ubuntu install for somebody else on a uefi-pc with windows8. The problem there was that at windowsboot the linux files in the efi partition where corrupted. I saved the windows directory on usbstick and deleted the uefi partion. Then I did a new instal where the uefi-freespace was repartitioned an rebuild by the linux installation (manual selection, efi special partition). After this install linux runs and I copied the windows dir back to the efi-partition. After this action windows and ubuntu where selectable at boottime (f8) and run ok. About the corruption read the following link. http://www.h-online.com/open/features/Linux-and-Windows-8-Fast-Startup-puts-... Succes, Hans On 13/01/13 12:38, richard -rw- weinberger wrote:

Hi!

Installing OpenSUSE on an UEFI system seems to be a real PITA. I'm not talking about secure boot.

My new notebook (Thinkpad u430u) support a legacy boot mode, but in this mode vt-d does not work. The kernel does not boot (no output at all, also nothing using earlyprintk). So I have to use UEFI.

But sadly both LiveCD and DVD do not support booting from UEFI. Netinstall boots from UEFI using ELILO but installing grub2-efi fails badly. Yast seems to call grub2-efi-install with corrupted parameters. If i recall correctly the output was "Please specify source_dir".

How do you guys install/use OpenSUSE 12.2 on pure UEFI systems? Again, using legacy boot is not alternative for me.
