Windows 7: Diskpart Clean All Error

I have the USB first in BIOS, it still gives me the error.

I'm assuming that's the F12 option. The USB was first there too, I chose it but I still get the BOOTMGR error.

I think I will have to try that, though I will have to go get some DVD's. I got the ISO from my college's software website, from a VPN connection so I wouldn't think the file is corrupt in any way.

According to your past link, I can reset the CMOS by putting back BIOS to its default settings. I tried it, but obviously it resets everyting, including the boot order, back to factory settings, with the HD second after floppy. I've set it back to factory and only changed the boot order so USB was first, but it hasn't worked.
Also, my HD shows up fine in BIOS, along with one other drive, and they both are enabled.

Any other suggestions are greatly welcome. I will try the DVD method and see if it will let me boot.

It could well be skipping over the flash stick because it is faulty, which woudl also explain the install fail. So it's a good idea to cross-check with DVD install.

Check the ISO hash against official Hash here: Windows 7 RTM SHA-1 hash / checksums

Burn the DVD using ImgBurn at 4x speed with Verify so there's no question.

Good quality DVD's are 3 for $2 on photo rack at Walgreens.

I burned the iso to a DVD at 4x and it worked just fine, HD came up and everthing. The boot USB was definitely the problem.

Thank you very much for all the help, it was very accomodating!
