Cannot reboot after upgrade from Ubuntu 9.10

[John Truine]

I tried to up grade to Unbutu, 10 the old & new are on a partition on my hard drive , my first operating system is Vista & I have had no problems up to now running both systems. When the upgrade was almost finished I checked the box about GRUB I think I should have left it unchecked . and now the boot up will not proceed beyond saying no such device & the a number which I thought was my hard drive number I think I was wrong. What do I do now as the only way to make the computer work is to boot up from my disc drive using my Ubuntu disc.

Thank you for taking the time to report this issue and helping to make Ubuntu better. This isn't yet definite enough to be a bug report, so I'm closing it and converting it to a question in the support tracker, which is better-suited to dealing with this kind of thing. It may become a bug report again later once a volunteer has worked out what the underlying problem is.
