please help meeeee... please help me with the codes which i have to enter and where to enter. coz i'm a newer person to linux . i want to study all about linux . so firsr i want to install it. please help

I assume that you mean UBUNTU 7.10 ?
If that is correct than it is a rather out dated version.
So my first advice than will be try a newer of UBUNTU .
Monitor out range can mean that the input refresh rate is too high assuming that you're monitor is LCD or TFT
TRy to boot in verbose mode to see if iut comes with error messages

I assume you mean Ubuntu 9.10, but telling us the correct info is better than letting us guess.

There is an initial boot menu (probably with default choice and timeout) that you get to earlier in the bootup process. From that menu, there are ways to add bootup options that select a different display driver, a specific display resolution and/or a lower refresh rate. But I'm not sure of the details for all that in Ubuntu and the info you see in that menu probably doesn't make your options obvious.

Alternately, after you let it boot up incorrectly, pressing CTRL-ALT-F1 will switch you to text mode. From there an experience Linux user would know how to edit the file /etc/X11/xorg.conf (using some beginner friendly text editor such as nano) to limit the resolution and/or refresh rate, then stop and restart X11 and the desktop manager in oder to get the GUI running correctly.

But I don't think I know that process well enough to talk you through it for unknown monitor on unknown display card on maybe unknown version of Ubuntu.

i'm a new user dont know the codes to enter. please help

First, someone asked what version of Ubuntu. Is it 7, or 9??? Again, 7 is VERY old, so if this is a new install, get the latest version of Ubuntu, and load it.

Next, you say your "monitor" says that. How about telling us what KIND of monitor? What kind of video card? We're not going to guess. And not sure what you mean by "codes to enter". There are no magic 'codes'...either your monitor supports the resolution you chose, or it doesn't. YOU need to look at the specs on your monitor, to see what it supports.

You can boot into 'rescue' mode with your install media, and a quick Google search turns up many answers to changing your screen resolution...did you bother to try to look this up?
