[SOLvED]Installation restore after BIOS update. UEFI doesn't boot.

Hello.

In order to solve my trouble with firewire on my motherboard in was adviced -in the FW mailing list- to update the BIOS. As expected the boot entry created with efibootmgr was erased but thats fine and i knew it was going to happen.

The problem however is that neither archboot (USB) neither archiso (CD) nor ubuntu12.04 (USB) can boot into it so i can restore the uefi entries.

All hang with a blank screen. Ubuntu and Archboot booted fine in UEFI mode before the update.

I tried nomodeset, acpi=off and noapic but ended up with the same blank screen and no messages at all.

I also tried booting it through the UEFI shell which works with Archboot but it hanged again. No blank screen this time juct hanged at the shell. I used:

img_name.efi root=/dev/sda3 ro rootfstype=ext4 add_efi_memmap initrd=\EFI\arch\initramfs-linux.img

I assume this is unexpected behavior... what motherboard do you have?

I downgraded to the previous (83) and to the original (70) and it doesn't boot in any of those two in UEFI.

It worked fine with version 70 before the morning update.

I had to downgrade to version 57 which was what the motherboard came with and as it appears its the last version that boots Linux with UEFI. The Intel people don't care about linux on this board so it probably won't be fixed.

Marking as Solved.
