Win10 cannot update the upgrade under the UEFI boot mechanism.

The boot mode of Win10 system is divided into BIOS boot and UEFI boot. If the computer joins the Win10 UEFI boot mechanism, it may not be possible to update the upgrade. What time is this? Do it? 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. Enter the List disk command and press

to determine the next operation according to the number of hard disks displayed on the screen.

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.
