I'm running Ubuntu 11.04. I just don't understand it. It doesn't matter if it is a kernel upgrade, or an Adobe Flash update. The next time I restart my computer Grub2 breaks. All I get is a blinking "_". Then I have to boot into a live CD, mount my FS, run
sudo grub-setup -d /media/FS_NAME_HERE/boot/grub /dev/mapper/isw_blah_blah_blah
and then restart, then run
It only happens when there is an update. Because if I don't run anything, and I make sure to run sudo
update-grubafter I reinstall it then I can restart as many times as I want--but only until I update something else.
I'm 70% sure everything still works after I install something new. If it'll help I'm running a Sony Vaio Z. There are 2 solid state chips on board that are in a raid0 array. I've never had this problem before I just switched back to Ubuntu.
