Win10 can not be updated under the UEFI boot mechanism

The startup mode of Win10 system is divided into BIOS startup and UEFI startup. If the computer joins the Win10 UEFI startup mechanism, it may not be possible to update the upgrade. What should I do at this time? Let's take a look together.

Operation steps:

1. Enter CMD in Cortana search bar, then run in administrator mode

2. Enter diskpart.exe and press

3, the carriage return command input List disk

the screen shows the number of hard decision next operation.

If there is only one hard disk:

1. Enter the List volume command and press

2. Select the drive letter with the boot partition (usually C drive), remember Volume number

3, run command

Select volume X (X is the number remembered in the previous step)

Shrink desired=50 minimum=40

Create partition msr

4. Enter the command List partition to confirm whether the MSR partition is created successfully

The above is the solution that Win10 cannot update under the UEFI boot mechanism. After re-creating the partition, you can Make Win10 upgrade normally.
