I called Microsoft for help and you have to reset your Windows 10 to make it work again. You need a usb thumb drive 16Gb. I did it and it works for me.
Here's the instructions from Microsoft:
As we discussed earlier, I am providing you with the instructions on how to create a USB recovery drive for your Surface.
Download and create a USB recovery drive
To download the recovery drive, you'll need:
A PC running Windows 7 or later.
A USB drive with a storage capacity of 8 GB or larger (16 GB or larger for Surface Pro series)
Important Creating a recovery drive will erase anything that is already stored on your USB drive. Make sure to transfer any important data from your USB drive to another storage device before using it to create a Surface USB recovery drive.
Visit the page at https://support.microsoft.com/en-us/surfacerecoveryimage
Sign in with your Microsoft Account (this is the email address we asked you for at the start of the call)
From the list of Surface devices available, select the device that you need a recovery image for Please note that while you will only be presented with devices that are currently registered on your account, you will also be presented with the option to get
an image for a different type of device. If you try to use this option, you will be prompted to enter the serial number for that device
Download the recovery image using the button on the page
When the download bar pops up at the bottom of your screen, save the file in a location you will be able to find it.
Create a recovery drive:
Insert your USB drive into the USB port of your PC.
From the desktop, open File Explorer
Tap and hold or right-click on the USB drive and choose Format
Select FAT32 as the file system and enter a Volume label to name the USB drive, such as RECOVERY, and then tap or click Start
Tap or click OK to erase the contents of the USB drive
Tap or click OK when the format is complete
On your PC, open recovery image that you downloaded by double-clicking it
At the top of the window tap on Extract and then Extract all. Select the USB drive you formatted earlier for the location and click Extract.
Use a USB recovery drive to reset your Surface (Cannot load Windows):
Make sure your Surface is turned off and plugged in, and then insert the USB recovery drive into the USB port.
Press and hold the volume-down button while you press and release the power button.
When the Microsoft or Surface logo appears, release the volume-down button.
When prompted, select the language and keyboard layout you want.
Select Troubleshoot, and then select Recover from a drive. If prompted for a recovery key, select Skip this drive at the bottom of the screen.
Note:Be sure to select the Troubleshoot option on this screen. Don’t select the Use a device option. If you select the Use a device option, your Surface will reboot from the USB recovery drive again and the reset process will start over.
Choose either Just remove my files or Fully clean the drive. The option to clean the drive is more secure but takes much longer. For example, if you’re recycling your Surface, you should clean the drive. If you’re keeping your Surface, you just need to remove
your files.
Select Recover. Surface restarts and displays the Surface logo while the reset process continues. This can take several minutes.
