A while ago when i tried to install windows 7 on an XP disk when trying to boot windows 7 install from cd i got the message something something config file is missing.

I just decided to install it on another hard drive and instead now just use the drive for storage space.

I tried again to install windows 7 on it today, got the config missing error, so i quick formatted the drive and now i get the message "No Operating System Detected" when trying to boot Windows 7 or Boot and Nuke.

I thinking of doing a more thorough format, but i'd have to do one while keeping my computer running.

Has anyone got a solution?

When you formatted the drive, you destroyed everything you had on it.

Do a clean install and start from scratch.

I'm not exactly certain about what you did but I'm wondering if you have your boot record on one drive (the one you formatted) and the os on the other drive (I don't know if this is even possible with windows). You could try to restore your boot record by booting from the installation dvd as per instructions here
This is very quick and easy to try but I'm not sure it will help you

I know i deleted everything, i have been trying to do a clean install.

The quick format didn't quite destroy everything it seems, as when i did a more thorough windows NTFS format the message i get when trying to boot from disk with only the faulty drive attached to the system changed to:

Bootmgr Is Missing

I cannot boot from CD with that drive in the system.

Someone on another forum suggested to someone facing a similar problem that in 90% of cases, this is due to using a wifi keyboard, coincidentally i do, the computer not recognizing the wifi keyboard apparently prevents the press any key to continue from coming up.

I don't know whether to buy a cheap keyboard and put this theory to the test or not.

In any case my drive is in warranty with Western Digital, i think I'd have to send the drive to them however and I'd personally like to have nuked the drive before i sent it back, I've formatted it, has this made data recovery unlikely by Western Digital? Could there possibly be a reason why they'd even try?

Scotteq is correct -- it sounds as though when you formatted the hard drive, you deleted the bootmgr. You will need to perform a "clean" or custom installation which will require you to reinstall your applications.
