Laptop E6430 ATG -invalid partition table

Hello,

I have a problem with a laptop and i don`t know how to fix it.

I have 10 pcs. laptop Latitude E6430 ATG with docking station

I broke the screen on one of them

I want to change the HDD between two laptops. The hardware configuration are identical.

The software are nor identical - one have Windows 10 and one have Windows 7.

When i try to change the HDD on the display i have the message: invalid partition table and the laptop don`t boot.

I mounted the HDD as they were before and both laptops work.

How can i change HDD between them without losing information
