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=707382
Now 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.
My main(/only) point is that if the boot loader menu never shows up then the problem is not in installed packages: it is either in the bios, or the boot loader itself. The latter is much more likely, and in an MBR/bios system, the fix would be to reinstall the bootloader to the mbr - so I think what is needed is the equivalent step for uefi.
]]>The Arch Wiki-Grub 2 says that you need to boot in UEFI before you can (re)install grub2.
As my live-cd won't boot in UEFI mode, the only option is that I make a live-usb stick and see if that one will boot in UEFI.
But in the end it is still strange that a software update breaks my Asus UEFI-boot.
I just found another unlucky guy with a simular problem. I'll try his solution tonight.

I will try the live-usb method and report on it later.
I placed an complete image back onto my SSD. So all 4 partitions.
The SSD should be bit-for-bit identical to what is was when everything worked fine.
Or do I miss something?
And you need to boot with EFI in order to be able to reinstall grub to the EFI-partition.
And booting with EFI (even with live-cd) does not work.
I did not know if they had anything to do with systemd, I just thought so.
I shoudn't have done a partial upgrade, sorry!
That's why I put my system back into it's original state with my backup-image.
When that didn't work, I asked help in this forum.
I hope somebody else could help me.
]]>Last week I updated several pacakges by hand (kernel, vlc, ...) : All updates that according to me didn't involve with systemd.
Partial upgrades are not supported. According to you they may not have anything to do with systemd, but how do you know that?
Anyways, best of luck with solving the problem
]]>problem : after update my computer refuses to boot. It doesn't get to the grub2 (actually 1.99) menu, it just says : no boot device found.
My hardware : Asus M8Z77-V LX motherboard with 1 SSD.
In the bios I disabled the bios legacy option to force it to boot with UEFI.
As I hadn't moved to systemd yet, I waited to update a while(2 months).
Last week I updated several pacakges by hand (kernel, vlc, ...) : All updates that according to me didn't involve with systemd.
Then I rebooted and ... problem.
I have tried a whole weekend to solve it by browsing through the wiki's but to no avail.
I can boot with live-cd and access my SSD. All data is there. I can also chroot and do stuff.
The SSD is partitionned in GPT as follows :
sda1 : 1 gb fat 32
sda2 : 20 gb ext4 root
sda3 : 20 gb ext4 var
sda4 : 79 gb ext4 home
I did not do any update of my bios or changed anything on my hardware.
It seems that my bios does not see my SSD as UEFI-bootable device anymore.
When I installed Arch in June on my brand new computer I made a backup with redobackup (partclone) of a working installation.
As a final ressort I put back the image I created then.
But it doesn't work either!
Then I updated my bios but same problem.
My bios can see the fat 32 partition. I know this because to update the bios it looks for attached fat 32 storage and there is shows the partition .
I there anywone who can point me in a good direction?
Thanks a lot in advance.
