Factory reset Surface Pro without recovery partition, disk or image

The Surface Pro if installed with custom build before creating the recovery disk, it is not possible to reset it by selecting the reset options from the Windows Setting.  Here is the way to reset or re-install the Surface Pro to factory default when the recovery partition, image or disk been deleted.

First of all, you will need the following to complete the task,

• Windows 8 or Windows 8.1 Pro version image (ISO) file
• USB disk with 4GB or above
• RW-Everything, a tool can extract the OEM product key from your Surface Pro device
• Rufus, a tool to create bootable USB for you

There are many ways to create the UEFI bootable USB disk, but this is the simplest I experienced so far.  This is a zero install tool, with your ISO image and USB disk ready, launch it and configure the following to build the bootable USB,

1. Select the USB device to be use
2. Select the ISO image by clicking the disk icon
3. Select Partition scheme as MBR partition scheme for UEFI computer

Please follow the sequence as by selecting the ISO image, it will reset the partition scheme

Now you have the USB bootable disk and the OEM product key. With the Surface Pro turned off, connect the power cable, plug in the USB disk.

To boot the Surface Pro from the USB, you will need to do the following,

1. Hold the volume down button
2. Click the power button once
3. Keep holding the volume down button until the Surface logo loading finish

You should now see the Windows setup screen if successfully boot to the USB.

Just follows the instruction to re-install the Surface Pro by selecting Reset your PC, delete and select the only partition left.

After re-install, login to the device and go to Windows updates, run the Updates now, which should guide you to the latest firmware.

From the settings, select activate Windows, provide the OEM key for your device.

It is done !
