Step 2: Launch a Command Prompt
All typing from this point will be done in this same window.
Step 3: Type: DISKPART {ENTER}![]()
This will start DISKPART.exe, which we will use to get this drive formatted and bootable.
Step 4: Type: list disk {ENTER}
This will give you a list of installed disks, but they are labeled using the disk's number, not the name or drive letter (though it does show the size). If you are not sure which disk you want, open Disk Management, they are listed by all three identifiers there.
Attached is a pic of what this looks like on a Windows 7 machine.
WARNING:
If you select the wrong disk here, you will lose data, and possible overwrite your OS. Be sure you have the right disk selected. Step 5: Type: select disk x {ENTER}
Where x = the disk number you want to format. Dmg compassion review.
In the case of the example image it would be Disk 3, so to select the disk, type: select disk 3 {ENTER}
Remember to substitute the correct number for the disk you want to select.
Step 6: Type: clean {ENTER}
This will wipe the disk.
Step 7: Type: create partition primary {ENTER}
This will create a new partition on the drive.
Step 8: Type: select partition 1 {ENTER}
This will select the partition you just created.
Step 9: Type: active {ENTER}
This will set the partition to active (this is what allows a computer to boot from a drive).
Step 10: Type: FORMAT FS=FAT32 {ENTER}
Wait for it to get to 100% complete, this will format the drive using the Fat32 file system.
Step 11: Type ASSIGN {ENTER}
This will assign a drive letter to the drive in Explorer.
Now you should have a USB disk ready for the OS source files (you can either extract them directly from an ISO file, or just copy them from an install disk).
Using this, I was able to install Windows 7 x64 on an HP Elite 7000 in just under 7 minutes from first boot to desktop.
