Reason 1: SSD Is Not the First Boot Option

Computer will not boot from the cloned SSD until it is set to be the first boot option  in BIOS. In this case, you just need to change the boot order in BIOS settings and select the SSD as the first boot option.

Step 1: Restart the PC. When the startup screen appears, constantly press the hot key to trigger the BIOS settings. Generally, the hot key is F2, F8, F12 or Del.
Please use the correct hot key to enter BIOS according to the brand of your PC.

Step 2: After you go into BIOS, use the arrow key to choose the Boot tap and select the SSD as the first boot option.

Step 3: Press F10 to save the settings. Then restart your PC.

Reason 2: Partition Style Is Not Compatible with Startup Mode

There are two types of partition style: MBR and GPT. MBR works with the startup mode Legacy. And GPT works with UEFI. If the partition style is not compatible with the boot mode, cloned SSD also won’t boot. So we also need to enter BIOS and set the correct boot mode according to your preset partition style.
Step 1: Repeat the above Step 1 and enter the BIOS utility.
Step 2: Use arrow key to choose the “Boot” tap and select “UEFI/ BIOS Boot Mode”. Press Enter. Then select “Legacy” or “UEFI” according to your preset partition style.

Step 3: Press F10 to save the settings. Then restart your PC.

Reason 3: System Partition Was Not Set As an Active Partition

Generally, active partition should be a primary partition. The boot files of the operating system locate in primary partition. If the system partition is not set as an active partition, Windows 10 won’t boot after cloning to SSD. We could change the active partition via Command Prompt.
Step 1: Because cloned SSD won’t boot and we could not get into Windows 10, we have to boot from the old hard drive. Then put the SSD in the hard drive enclosure and connect the case to the PC.
Step 2: After you boot from the old hard drive, press “Win” + “R” to open Run box and then type in: diskpart. Press Enter.
type diskpart to run
Step 3: Once a window pops up, type the following commands in the Command Prompt. Please press Enter after you type a command each time.

list disk
select disk XX (Note: “XX” refers to disk ID of SSD)
list partition
select partition XXX (Note: “XXX” refers to the partition ID of your SSD)
active

Tips: Figure out your SSD ID via Disk Management
a.Press “Win” + “R” to open Run box and then type in: compmgmt.msc. Press Enter.
b.In the “Computer Management” window, click “Disk Management” in the left pane. Then you will see the details of disks and partitions.
change active partition
Step 4: Restart the PC after completing above commands.

Reason 4: The Black Screen Occurs upon Startup

When starting, the PC usually gets the boot code from MBR/DBR on the hard drive. If the boot code gets damaged, it will lead to the black screen problem and we could not get into Windows 10. In this case, it’s suggested to deal with it as soon as possible and use the third-party software to fix MBR/DBR.

It’s recommended to use Renee PassNow which can fix the Windows startup problem by a few simple steps. Besides, Renee PassNow also provides password reset, data backup, disk scan, drive eraser, data transfer, data recovery, etc. Need to fix the black screen issue? Please refer to the detailed instructions of fixing MBR/DBR.

Reason 5: Error Code 0xc000000f Appears upon Startup

Once BCD file is damaged or missing, the error code 0xc000000f will appear. BCD is a boot configuration database which is used for booting a PC. If BCD is missing, you will not get into the system. Here’s how to restore BCD file:
Step 1: Download and install Windows 10 Installation Disc. Boot the PC from Windows 10 Installation Disc. Then click “Repair your computer ” to go into Windows Recovery Environment.
Step 2: After you enter the Windows Recovery Environment, navigate to “Troubleshoot” > “Advanced Options” > “Command Prompt”.
select command prompt in advanced option
Step 3: Type the following commands in the Command Prompt. Please press Enter after you type a command each time.

bootrec.exe /fixmbr
bootrec.exe /fixboot
bootrec.exe /scanos
bootrec.exe /rebuildbcd
