yes, it is possible to install windows xp over an already installed/corrupt installation without formatting the hard drive. to do this choose the option given by the startup disk CD "repair a previous windows installation" you will find it should correct your current windows issues, however doesn't delete all your files, it does however move all your files under documents & settings, user, and may take a bit to find, because the direct path will not be there anymore. this will correct many windows issues, but if you find it does not correct them all, it is recommended to redo the win xp CD install & format everything. reason being is that many bugs & virus's affect or change your windows or registry files, sneaking their way into your bios configuration. in most cases, it is still recommended to backup important files to disk or CD, and format the whole machine with restore, clearing up things that would just be relocated with xp restore/repair.
AnswerI was also very hesitant to do so but it turned out to work floorlessly. It simply repaired and reinstalled default window components that might have been changed or corrupted. After the install and boot was complete windows ran brand new, not a single item touched even the background pic was the same.You Simply Can't...
Well, without harming your computer, i would say that everything is risky. Reinstall your Operating System, but before you reformat and reinstall the OS. Backup all your important files on CD and Email, and another computer. Once you reinstall, the virus will be completely gone, risk-free.

Any application not written for Windows can be used without Windows.

Partitioning allows you to create a logical separation between different operating systems and data. For example, you could have a windows operating system on one partition, a Linux operating system on another partition, and your personal data (My Documents in windows and /home in Linux) on a third. This allows you to wipe one of your partitions clean and reformat without having to backup the data on the others (say for example, your windows install gets a virus).
Reinstall the operating system or if you have the password simply reset it at "Control Panel".
you have to boot from something else, whether it be a floopy disk, thumb drive, or setup cd. you can't delete files that you are currently using. if you boot into windows xp you can't delete windows xp.
If you are talking about programs, you can't. If you create a dual boot system, the programs will have to be installed on each operating system (actually the program does not reinstall but it does register the files for each of the operating systems). Data files don't care where you put them. You may have to search for a known file name to find them.
Windows NT is a very old operating system. The technology for PNP was not available when NT was written.
