SOLVED - Computer power turned off during kernel upgrade

I was performing a system upgrade this morning - in the process of installing the new linux kernel, KDE power management turned off computer (thanks).  Now it seems I can't boot the computer trying both options of regular boot (both default and fallback).  Both complain about not able to mount root file system.  If I boot to live CD, is there any way to fix this problem?

Re: SOLVED - Computer power turned off during kernel upgrade

It sounds like the new kernel got installed but the initramfs didn't get re-created. If that's the case, the most straightforward solution is to chroot to the install then regenerate it. Or you could skip the chroot and just run mkinitcpio from the live environment, but it wouldn't be so simple as 'mkinitcpio -p linux'.

Booting into a live CD will let you fsck the drive, mount the os into /mnt and use arch-chroot to install a new kernel and update grub.
