If your model PC came with Win10 preloaded, then it was loaded at the factory using UEFI mode -- and setting it NOW to Legacy mode will accomplish nothing.

You need to change it back to UEFI mode, and then see if rebuilding the boot files gets it working again.

If your PC can not boot into Windows, a way around that is to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to rewrite/repair the boot media on your PC:
1) Download and install Macrium Reflect (MR) from this link on a working PC: http://www.macrium.com/reflectfree.aspx
2) Use the option to create a boot USB stick or CD

That will create MR bootable media. Then, you can boot your PC into WinPE using that media.

Have patience, as that can take a while to start and bring up the screen.

Once the screen is there, select the option to Fix Windows boot problems. It will then search for the OSs installed and list them, Select the one you want to repair and click Next.

It will now do the repairs, listing the things it has done.

When finished, select the option to Restart the PC.

If this worked, the boot repair succeeded and you will have your PC back.

Thnx i try macrium free version  but i dont have active partition . i dont know why 😕

The Active partition is the space containing the boot files, not the space containing the OS files.  This is usually a smaller separate partition from the OS.

MR can repair the OS partition to include the boot files and will set it as Active.
