The last build here had one!

That was when trying to install Windows 3.1 on a virtual hard disk which didn't!

:sarc:
The iso will be your concern there however since you need to make a bootable cd with that and simply ignore the rest for the time being. Those are simply included for the floppy option if available like on an old boat anchor.
Once you see a good burn even with the WD iso and it loads properly you should see the results in only a few minutes once the scans complete.
Meanwhile I have to ask if you had oced anything lately like memory? That can stall 7 at the startup logo or prevent a good install if you have the memory clock raised up on the board at all. When trying a few things out on the new build here the clean install just seen on a new drive would stall at the logo screen! Once the memory clock was back on auto 7 loaded right up like nothing ever happened!
