Comment 27 for bug 576724

I know I'd mentioned previously how updates that triggered reconfiguration of grub 2 in Squeeze follows the safer and saner behavior of displaying only drives rather than drives and partitions, but I recently did a reinstall of Karmic and it does likewise. So this only effects Lucid, and having followed it's development from day one I'd swear this behavior changed only towards the end of the Lucid development cycle.

How critical is this bug? Well, to quote Arpanaut on the forums:

"We want them to throw windows out of their PC's
Not their PC's out the window."

This effects anyone and everyone who is not familiar with Linux device designations, and it's extremely critical for Windows users. I'd guess about 2% of Windows users effected by this have been unable to recover from this without having to reinstall.
