view story

https://bbs.archlinux.org – Hi,thanks for this link. I will examen it this evening.Yesterday evening I already found out how to boot.My solution came from : http://www.overclockers.com/forums/show … p?t=707382Now I know that my Arch installtion is still fine.The only problem left is that my solution is not permanent.After each boot I have to boot in a UEFI shell and start grub that way.With this new guide you gave, I probably will find a lasting solution.UEFI is not ready for prime time according to me.Thanks.I'll mark this thread as solved.
