XPx32-win7x64 student offer download help.

K so ive been looking all over the net looking for some help on this but all the help i find includes different files to what ive got. K so these are the files i have

I need to make an iso to burn onto a dvd and then boot. I found this guide here How to Create and Make Bootable Windows 7 ISO from EXE Plus Setup1.Box and Setup2.Box Files My Digital Life which goes on about setup1.box and setup2.box files which i dont have and also this guide How to make a DVD of that student-only Windows 7 you bought for $29.99 which talks about some expandedsetup file which again i didnt get with my download. so im woundering what i need to do to make the required iso with the files i have, any help would be most apreciated. Thx in advance.
Note: I just noticed that i acidently had a text file in the folder when i made an iso earlier and when i tried it it didnt work, could this text file of been the reason why it wouldnt boot properly? i dont have another disk on hand atm so i cant find out formyself untill tomoro.
