cgregory,
Appears that you are doing everything correctly.
I also always install from USB. I also use DiskPart to prepare the USB drive, then I just copy the DVD over to the USB stick.
I have run across defective USB sticks.
I use the Clean ALL which is going to mark any bad sectors as bad so that when you copy over to the USB stick, the bad sectors do not get used.
If you feel up to it, then here is how I prepare a USB:
PREPARE A UFD FOR USE (USB FLASH DRIVE)
Run CMD.EXE as administrator
WIN | type CMD.EXE | do NOT hit ENTER | CTRL + SHIFT + ENTER key combo |
ALT + y key combo
WIN=key with Microsoft logo on top
Type following commands and hit ENTER key after each command.
DISKPART starts the DiskPart program
LIST DISK shows numeral assigned to disks
note the numeral assigned to your usb stick
The numeral 2 will be used in this example
SELECT DISK 2
DETAIL DISK the info shown will confirm the correctness of your selection
CLEAN ALL the entire usb stick will be overwritten with zeros
This can take awhile if usb stick has large capacity.
Keep the faith-the DiskPart prompt will eventually return.
CREATE PARTITION PRIMARY create a primary partition on the USB stick
FORMAT FS=NTFS format the partition
ACTIVE the partition can contain operating system startup files
ASSIGN the next available letter is assigned to the USB stick
EXIT exit from the DISKPART program
EXIT exit from the command shell
===========================================
After doing this, I then right-click on the drive in windows explorer, Properties,
Tools tab | Check Now button | checkmark both boxes | Start button
=================================================

Here is how I put the ISO onto a USB. I've used both methods:
PUT A WIN 7-COMPATIBLE ISO FILE ON BOOTABLE UFD
1. Prepare UFD
2. Burn the ISO file to DVD by right-clicking on a ISO file and choosing Burn disc image or by using ImgBurn free iso image burner
3. Copy DVD to UFD
OR
1. Prepare UFD
2. Extract the ISO file to the UFD using 7-Zip
