Monday I did updates and saw Grub was going to be updated to version 0.96 or whatever the latest is. I didn't reboot at that point to test it.
Today (Tues.) we had a power outage and the power came back on immediately. When I turned the computer on, grub stopped at message, Grub stage 1.5 or whatever it had, and wouldn't continue to boot. I'm not sure what exactly caused it but I assume it was the latest grub.
Since I didn't have another Linux distro installed and couldn't boot into Win7, all I was able to do was using the M3A2 livecd to try and reinstall Grub but wasn't able to. I ended up reinstalling A2, since it was the latest disc I have.
Just thought I would mention this.
