Can't boot from external hard drive

I am trying to upgrade my HDD to a Crucial SSD of the same size. I tried to clone the HDD to the SSD (operating system also) through Acronis but it never worked no matter what I tried. I then tried swapping the disks physically and putting my HDD in the external enclosure, but I would get stuck in a boot loop in UEFI mode and Legacy mode will just say that the boot device has failed. I don't know what else to try, this method works on all other laptops i have seen on the internet. I even tried scanning my hardware but everything seems healthy, and swapping my HDD back into the system will boot as normal. Thanks in advance for the help!
