what is CoA label?
The Windows installation provided with a computer is licensed for that computer alone, unless it is a full retail version of Windows. If the laptops do not have a COA label containing the product key, the Windows may not be a legitimate installation.
If you really need to use the hard drives the other way around to how they were supplied, the way to do it would be to image each drive and transfer the images between drives. That way the Windows belonging to each computer stays with that computer, and the only hardware change being the hard drive should not trigger activation.

COA is Certificate of Authenticity, and systems with this should have a small label attached, of this style:

it worked thanks, but do you have any idea why this happened? I've never had this happen before while switching laptop harddrives.

In one way or another it comes down to the OS being keyed to the hardware. The Compaq I needed to reload last week picked up its code from a BIOS tattoo, Because the HDD had failed & lost the restore partition, I had to load Windows from a DVD. The product key from the CoA sticker didn't match the Windows type, so it could not activate - I needed to do a manual activation by phone, no drama. But even if there isn't a hardware tattoo, exceeding the hardware change "score" by using Windows on a different mainboard will usually trigger activation.

There are hardware identifiers related to the motherboard which can result in the operating system malfunctioning. The operating system recognizes the identifiers related to the motherboard it is installed with. When the hdd/ssd is moved to a different motherboard the operating system sees the new identifiers and basically becomes confused. This can result in the operating system not being able to boot.
