Surface Pro 6 only boots in UEFI - possible causes

The UEFI actually only starts on the Surface Pro 6 if you hold down the volume down key while turning it on. On the other hand, if the device starts directly in UEFI mode, this may be due to the boot manager.

This is what UEFI mode is used for on Surface Pro 6

UEFI mode is used on Surface Pro 6 to adjust various settings of the device. Besides changing the boot order, you can turn safe boot on and off and enable or disable connected devices in UEFI. Moreover, the UEFI will show you important information such as the serial number or firmware version of your Surface Pro 6.

This procedure helps when the Surface Pro 6 only boots in UEFI

Normally, your Surface Pro 6 will only boot in UEFI mode if you press the "Power Button" and the "Volume Up Button" at the same time when you turn it on. However, if the UEFI page appears even during a normal startup, this can have several reasons. First try to solve the problem by going to the "Exit" section on the UEFI page and selecting "Restart now".

1. A defective boot manager can also be responsible when the Surface Pro 6 starts in UEFI. If this is the case, your only option is to restore the device using a USB recovery drive.
2. Connect the USB drive where the recovery image is stored to the Surface and restart the device while pressing the Shift key.
3. Then go to "Troubleshoot" > "Advanced Options" and specify that the Surface should be restored from a drive.
