To start with your using the wrong software to clone  try Macrium Reflect Free ATH has always had an issue restoring UEFI bootable drives/SSD ensure you boot your recover media to start the clone In UEFI Mode this is critical. I have never had a failure using MR to clone. My latest use is this 3440 Precision I cloned the 256GB m.2 NVME SSD that Dell shipped with it to my new Samsung 970 Pro 512Gb This very month  I cloned and then shut down, I then removed the old 256gb SSD and installed my new 970 EVO Plus 2 TB  Booted up on the new SSD and formated the new 2 TB SSD no issue. it just works every time  
Dell Precision T8510 I cannot enter the BIOS setup of my system. 1. Powered up the PC, waited and pressed the F2 key as soon as the first light showed on the keyboard. PC will not boot up. The power is heard running almost forever. 2. Powered up the PC, waited and pressed the F12 (for boot sequence) key as soon as the first light showed on the keyboard. PC will not boot up. The power is heard running almost forever. 3. I installed a new PCIe drive I cannot see in Computer Management, so I need to check the BIOS, ubt I can't. Thanks.
