You mean 'safe mode', not 'standby mode'.

When the computer is loading the OS from your hard disks (before the 'cannot read from disk 2 error'), but BEFORE the Windows logo and bar show up, press F8. This will give you boot options. Start with 'safe mode with networking', because this will let you get online to get anti-virus and the like, but try Safe Mode by itself after that. (If you're not getting the options, you aren't hitting F8 at the right time. Just tap F8 every second or so when rebooting if you can't get the timing right)

If that doesn't work, try booting from your Windows CD and attempting an OS repair from the first options it gives you. If THAT doesn't work, you'll have to reformat and reinstall Windows. If you can't afford to lose your data, with your current level of skill you should just take the hard disk (or computer if you don't know how to get it out) to a CompUSA or something and have them give you CDs with the hard disk's data on it before you reformat.
