C: drive is failing in laptop - how to boot from a cloned internal HDD?

[aCowbell]

Thanks for reading.

My wife's Asus G750's C: (Windows) drive is currently failing (audible clicking noise and SMART diagnostic showing it is in BAD shape) but still works.

I have another internal HDD - currently the H-Drive - onto which I have cloned the C: using Macrium Reflect.

My plan is to get rid of, and replace, the C: drive as soon as possible but I need to know if it is possible to boot from the H: drive in the meantime so that my wife can still use her computer while we sort out a replacement data drive. We're currently living in France or I'd have already gone to buy one and sort it out that way.

Can anyone let me know if there is something obvious I am missing or if I am doing this entirely the wrong way? I would be very grateful for help as I'm fairly sure C: isn't going to last much longer.

Thanks very much for your help!

Hey there, aCowbell.

You should be able to boot from the other HDD (as long as it's not an external drive) if the cloning process was successful. Why don't you give it a try now. Restart the computer and enter the BIOS/UEFI. Find the boot priority menu and set the clone as the first booting device. If you boot to Windows successfully that should mean that everything worked out fine and you should be able to remove the other drive.
Sometimes in cases like this one you might have to switch drives in order for the computer to be able to boot from the clone (what I mean is to disconnect the faulty drive and connect the clone to its SATA port).

Hope that helps.
