Don't delete the OS.  If DLL files are missing, you may need to either reinstall the programs they belong to, or get the files yourself.  This is a good source for them: http://www.dll-files.com/

There are several ways to do this. Simple way is as follows,\n\nWAY ONE:\n1) Click start button ->run and type "msconfig" (without quotes"")and click ok\n\n2)Navigate to "Boot.ini" tab. Now select the operating system you want to be as default under "[Operating Systems]" and click "set as Default" button.\n\n3) Click oK and restart.\n\n\nWay TWO:\n1) Rightclick Mycomputer and select "properties".\n\n2) Under properties window select "Advanced" tab and then "settings" under "startup and recovery" Title.\n\n3)Now select the default operating system in the list there and click OK.\n\n\nWay THREE:\nBy directly editing boot.ini file in c drive which is hidden. I dont prefer this one for normal users. If any thing got wrong neither of your OS wont boot.\nKeep this way as an Idea but dont implement it.\n\n\n\nCheers...!

go to BIOS (rapidly press delete or f10 during startup) and set your computer to boot to cd. Insert your os cd and run through the installation. at one point, you should recieve a prompt about drive partitioning. delete all partitions you see here, then create a new one, format it using NTFS (either quick or standard, you should see a prompt or the computer will do it for you) and then reinstall your os.\nHope this helps!

You should be able to unistall the old one. If they were windows, it should ask you to overwrite the old version.

You can only unistall it if you installed it as an "upgrade installation", otherwise you'll have to reinstall from scratch.\n\nIf you did install it as an "upgrade installation", then you can uninstall it by starting in "safe mode" and going to Start>Control Panel>Add/Remove Programs>select Windows XP.

Your best bet is to reinstall your operating system, and then create an account for yourself to use when you want to use the computer that has limited permissions (User versus Administrator).  That way, you can more safely enjoy your computer without worrying about deleting anything that is necessary to the operations of your computer.  Of course, this won't stop you from deleting stuff you might want, like music files or whatever, but at least you won't screw up your operating system.  Good luck.

Check with Compaq for specific instructions.  But, you can usually do a repair install (of Windows 2000 or XP), and it won't delete all your applications and user settings.
