Why does Grub2 break EVERY time I update my laptop?

  • 772

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

sudo update-grub.

  • It only happens when there is an update. Because if I don't run anything, and I make sure to run sudo update-grub after 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.

  1. Sometimes when the system is updated, it configures grub again. As I could see, you use a RAID array. You have to reinstall grub in the MBR of your array. That done, I don't think you will keep having this problem. Try BootRepair:
