@Arturo01 -- is this your computer: HP Compaq Elite 8300 PC Product Specifications | HP® Customer Support

It does not list anything about "mSATA", although it has a memory-card (such as in a digital camera) reader.

How old is the PC?

the model is 8300 USDT

@Arturo01 -- how old is your computer?

Given that it uses DDR3 RAM, and was originally shipped with Windows 7, it must be several years old.

If so, that web-page lists:

Ultra-Slim Desktop specifications
Expansion slots: (1) Mini PCI Express, (1) MXM, (1) mSATA

But, I do not see any information to indicate if the motherboard will (or will not) boot from mSATA.

I recommend that you actually try it, to see if it works for you.
