Yesterday, I wrote that Windows killed my laptop. A few updates, and my laptop wouldn't boot anymore - not to Windows, not to Linux, nothing.
Fortunately, I have a USB flash drive with Fedora 15 beta, so I was able to boot from that and get back to work.
A few of you suggested that one of the Windows updates had messed up the boot sector. I thought that sounded a likely culprit. A little googling, and I quickly found several suggestions to restore the Linux "GRUB" boot selector.
So, now my laptop boots again! That's Linux to the rescue.
