You can test the drive PW surface scan to find out for sure. Then zero and reformat.

Wasn't the issue that you hadn't yet formatted stick for UEFI as shown in screenshot detailing NTFS instead of FAT32?

No, I had tried both methods and neither would work.

For Step 8:
"8. Unplug all other HD's and peripherals except ethernet (to increase chances of it starting up connected), Boot the Windows 7 installer, choose Custom Install, then Drive Options (Advanced) to Delete all partitions not needed, repartition and format as shown in Steps 7 and 8 of Clean Install Windows 7."

Do I need to Boot into the Windows 7 installer, or can I just open up the USB straight from Windows 7?

Hello Abe,

When doing a clean install, it would be best to do it at boot instead for the best results.

Thanks again Brink!

Actually, could I just boot into the USB I made from the Boot Menu using ESC (HP comp.)

Yes. ESC to enter boot menu, then F9 (most HP computers) to enter boot device selection.

hello,
I have just got an OS from official site of my Home Premium 64 bit. and now I burn it into a DVD. So, now on installing the new OS, does it makes the older files like the windows.old and previous versions of windows clean completely? and if so is it gonna effect any of system processing in future...just a doubt.

First thing is do you want it to be completely clean?? If so then wipe the drive before you install.
Two methods I use are the command line clean all in DISKPART or the disk wipe using Partition Wizard.
Free Partition Manager for Window PC | MiniTool Partition Wizard Free Edition see pic

or

Disk - Clean and Clean All with Diskpart Command

If you get a windows.old folder then the installer was run from an OS and not booted. Always boot the installer. How to Boot A Computer from CD or DVD - YouTube

I would delete all partitions during the booted install to create and format new as desired. It explains how to decide on your partitioning in the sub-points of Step 8:

It shows the tools used to delete, create and format partitions during install in Steps 7/8 of Clean Install Windows 7.

Nothing more is needed unless there are installation problems, in which case running Diskpart Clean Command resolves most installation failures. If you want to wipe the disk first there is nothing wrong with doing that, though. Partition Wizard is another way to do it and is an excellent tool to have.
