Laptop battery of my Lenovo Ideapad S205 ran out of power while upgrading to 14.10. I connected it and powered it up as usual, but forgot about resuming the upgrade. Then I put it to hibernate, and since then it's stuck in a boot loop whenever I turn it on.
The BIOS screen will load and the fan go on, but then it will turn black and the fan goes off. Then it does the same again, on and on.
I can boot from live USB fine. I have chrooted and resumed the upgrade from here (dpkg --configure -a
, then apt-get upgrade
again) and configured Grub to show the boot menu (edited /etc/default/grub, then update-grub && grub-install /dev/sda
). But the boot loop remains. I guess it never gets to the point where Grub takes over.
Could it be that the hibernated session is broken and is preventing the boot procedure? Can I "clear" it? Edit: I tried to clear it with mkwap
as suggested, but had no success. Btw the root and swap partitions are LVM, but the /boot partition is ext2.
What else could cause this behaviour?
