Comment 11 for bug 400047

Thankyou for sharing concern and interest in this bug.
Yes, I'd agree with "Share the disk with existing installations, choosing between them when I start my computer" rather than "Install them side by side, choosing them each start up" that would make a lot more sense and would be a lot more clear.

"Install alongside the existing OS [ allows choosing between them when You start the computer ]"
This message doesn't seem to make it clear that you are not going to erase your existing OS.

Ubuntu's Installer's descriptions had improved a lot since Hardy Heron when I accidentally erased my Windows Partition due to confusion of my options. But until today, the descriptions had improved a lot. "Share the disk with existing installations, choosing between them when I start my computer" will definitely put an end to confusing options.

Thankyou
