I am new to Linux. Sorry for this naive question. I tried to format my HDD with Fedora installed in it. I did many things to format, change the MBR etc. and create two partition(one for fedora and other for XP) but I screwed up everything.

Now, when turn on my system I get the following message

Booting 'Fedora Core (2.6.18-1.2798.fc6)'
root(hd0,1)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.18-1.2798.fc6 ro root=/dev/VolGroup00/LogVol00
[Linux-bzImage, setup=0x1e00, size=0x1b1b3c]
Error 16: Inconsistent filesystem structure

Press any key to continue...

How to boot from DVD and re-install Fedora ? Please assist me.

Look in your BIOS and set the boot order to boot from DVD before booting from the hard drive. Then put your install DVD in the DVD drive and boot.

Boot order is set to first boot from DVD. Also, when I have the Fedora DVD in the drive, system read the DVD for a long time and shows me the GRUB commands for boot or edit. When I pick boot, system throws up the earlier quoted error message.

If it is getting to GRUB, then it means that it was not able to boot the DVD.

Did this same DVD boot previously, or is it a new one?
If it is new, did you burn it? If so, check to be sure you did not just copy the .iso file. The DVD should have multiple files and folders on it.
Other things to check:
Be sure the system will boot from some other CD or DVD.
Try the DVD in another computer.

Thanks for all your inputs. The problem was with my CD-ROM drive. I changed it with a drive salvaged from my old PC. Now everything works great
