At present I have a dual boot system with Windows 7 and Fedora 14. I want to re-install windows 7 but most probably it will replace Fedora's boot loader. I have a lot of things set up on Fedora. I want to keep these things intact. In other words, I want to make an image of my present Fedora system, re-install Windows 7 and have my Fedora system retain the exact state it had before re-installation of Windows 7. Can any one discuss the procedure to achieve this?

Simply reinstall Windows 7 and recover the GRUB. Technique for recovering of GRUB bootloader is Luckily covered in Fedora Manual:In many cases, the GRUB boot loader can mistakenly be deleted,  corrupted, or replaced by other operating systems.The following steps detail the process on how GRUB is reinstalled on  the master boot record:Boot the system from an installation boot medium.Type linux rescue at the installation boot prompt to enter the rescue environment.Type chroot /mnt/sysimage to mount the root partition.Type /sbin/grub-install *bootpart* to reinstall the GRUB boot loader, where *bootpart* is the boot partition (typically, /dev/sda).Review the /boot/grub/grub.conf file, as additional entries may be needed for GRUB to control additional operating systems.Reboot the system.
