How to install Windows 7 or 8 from USB using UEFI
In order to benefit from the new UEFI features (including faster system startup), you will have to prepare your USB device slightly different.
Main take-away here: UEFI accepts boot loaders in files placed a the FAT formatted boot volume
To prepare your USB stick (4GB minimum) manually follow these steps:
Open an elevated command
Enter list disk
Enter select disk # (where # is the number of your USB drive, in the example above it’s number 3)
Enter the following commands, keep in mind that all data on the USB device will be deleted:
- create partition primary
- select partition 1
- format quick fs=fat32
Mount or extract the Windows 7 or 8 ISO
Copy the contents from the ISO to the USB stick
- xcopy S:\* D:\ /s /e (S = the ISO drive or contents, D = the USB device)
Reboot your computer and enter the “BIOS” by pressing one of the F keys, this key varies depending on hardware manufacturer and model.
Enable the option “UEFI only” or similar option.
Save and exit, boot from your USB stick to start the installation.
