Whenever I try to boot into Ubuntu 12.04 from my USB Drive, an error pops up on the black screen saying :

EDD: Error 0000 while reading from sector ****** .

Then a few moments later another such error crops up and it doesn't seem to end. I have already searched the web regarding this topic and I have stumbled on this page:

Though apparently, he has described everything very well, I did not know what to do at all. Being a naive computer user, I had no idea what 'grub' was, where to find the menu.lst file (I tried searching in my USB Drive but I did not find it) and I am absolutely stuck.

I rule out any possibility of my files being corrupted because I have downloaded Ubuntu 12.04 only today and all the burning part and all went absolutely perfect. I had formatted it before hand and everything seems to be fine with it.

Format your USB disk and burn the ISO image with Unetbootin on your USB drive and make sure the USB device is working correctly. –  KashmirHackers Nov 23 '12 at 15:15
Make sure you do check the md5sum for the iso you downloaded: help.ubuntu.com/community/HowToMD5SUM . It is sounding like bad download, or a real problem with the USB stick or hardware. –  fabricator4 Nov 25 '12 at 1:50
