I successfully installed openSUSE 64 bit (DVD) using my USB drive.
I have kept it here:
User talk:Vaibhavkaushal123 - openSUSE
That is not-so-good guide. I know there is already one guide. But this one is just a contribution from my side to my favorite Linux community.
I dont know how to use the wiki properly. And I did not realize that I could put it here. I have not formatted it well 
because I dont know how to use the wiki formatting properly. SO I REQUEST THE ADMINS to kindly edit that page if possible. (and please improve the content if possible, please).
Thank you all.
PS: Now I have to run for my college. Will come back later.
