Can't boot ubuntu

Your monitor doesn't support the video mode that the installer is using. Try installing from the Alternate Install CD instead--that uses text-based install program. Then, once Ubuntu is installed, it is possible that you will receive that same message when it boots up. But on an installed system, that can be fixed. If that occurs after installation, please post again.

I've tried using the text based install and still nothing, the CD drive starts and almost immediatley the "signal out of range" messege appears. I'm at the point where I'm going to give up on linux and go back to using windows.

where it looks like Microsoft is my best option, and I really don't
want to do that.

This suggests a problem with your video card or monitor (or the cable that connects the monitor to the computer). Do you have another cable, or another monitor you could attach to your computer?

It is pathological for a video card or monitor not to support even a text display. Without changing the computer's hardware or figuring out what Windows is doing differently, you're right that you might have to go back to Windows to use your computer.

But maybe somebody else will have an idea. This comment asks a question and suggests a possible solution, but I'm going to leave the question Open (rather than calling this comment an Answer or Information Request) to maximize the chances that this will catch someone else's eye.

hi dear, i have the same problem, in LANs installation the computer crashes and Hang i d'ont know why
I have no problem when i install windows

hello all seriously speaking ubuntu's middle releases such as edgy(6.10,7.10,8.10,9.10) etc all are not too successful than compared to standard yearly releases so i wont switch in haste to these versions,i think you should stick to ubuntu lucid and try natty when it comes thanks

@cherrad fateh: Is your problem exactly the same? Your monitor says "signal out of range" when you boot from the install CD? Both with the Ubuntu Desktop Install CD and the Ubuntu Alternate Install CD?

As ajmal_82 seems to be suggesting, you could try 10.04 and see what happens. 10.04 is an LTS release, so while it's an earlier release than 10.10, it's actually supported considerably longer. You wouldn't ever have to upgrade to 10.10, as you could always upgrade to 11.04, 11.10, or even wait until the next LTS release (12.04). Some people find 10.04 to work better with their hardware than 10.10.

I don't see any reason why a non-LTS April release (like 11.04, when it comes out) would be more stable than an October release, though.

While there's no intrinsic reason for non-LTS April releases to be more
stable than October releases, it does seem to be something of a pattern
and we (various Ubuntu core developers who've been around long enough to
notice it) have remarked on it ourselves from time to time.

It's a subtle social problem so the reasons aren't obvious to us, but
they might include things like:

 * The cycle after an LTS, everyone tries to land the crazy stuff
   they've been thinking of that was inappropriate for an LTS

 * The cycle before an LTS, people try to land major changes in order
   that they'll have time to stabilise them for the LTS

 * The feature development cycle leading up to April releases is
   interrupted by the Christmas / New Year break, so there's less time
   to get major changes done

 * While we get a lot of feedback during the development cycle, the bulk
   of feedback from ordinary users comes after releases, so some degree
   of alternation in quality might result from that

Obviously, being aware of the problem, we'll try to do something about
it, although the fact that the causes are somewhat unclear means that
the solutions are also rather unclear!
