"This time, the buildup to the release of Karmic has been pretty significant, fueled to some extent by comparisons with Win7. But now that the release is available, suddenly there is are some complaints...
"As I have said previously, one of the biggest changes in Ubuntu is the switch to GRUB 2, at least for new/clean installations. I don't do upgrades on this kind of software, so I have no direct experience with that, but if I understand correctly, installing Karmic as an upgrade to an existing pre-Karmic Ubuntu release will leave Legacy GRUB intact. What I would say is, if you have never done anything or changed anything with GRUB or its configuration files, you're likely to be ok either way."
