[ubuntu] grub.cfg blank

view story

http://ubuntuforums.org – Hello all, since upgrading to 12.04 my grub.cfg file keeps getting overwritten with a blank one so my system always fails to reboot after a package update. I know the grub.cfg is autogenerated, but I'm not sure why it isn't getting generated correctly. I have reinstalled grub, and run a grub-update to no avail. Could anyone provide some advice as to how to debug this? (yes, I've googled, read the grub2 documentation, not understood it etc :-) (Hardware)
