SATA and NVMe are two popular storage technologies nowadays, and they are both used in SSD environments. However, these two types of interfaces differ in many aspects, including interface type, speed, form factors, physical appearance, price, security mechanisms, etc.

  • 💾SATA (serial advanced technology attachment) is an interface for transferring data between a computer's central circuit board and storage devices. It has replaced the previous PATA or parallel ATA interface and has become a commonly used interface to link HDD and SSD.
  • 💾NVMe(non-volatile memory express) is an interface specially designed for SSD to access data storage devices. It has better throughput and quicker response time than SATA, which is more suitable for high-performance, non-volatile storage media.

Due to its excellent performance, NVMe has become the first choice for most game players, editors, and businessmen. With people's demand for high-performance storage devices, the need to clone SATA to NVMe has arisen.

But a number of issues will come up during this process, the most frequent of which is Clone SATA to NVMe Won't Boot. A user case is as follows:

I'm looking for some assistance because I attempted to clone a SATA SSD to a larger NVME drive and the NVME simply won't boot after the clone. I initially assumed this was due to GPT, so I converted MBR to GPT using the command line and then cloned again. The existing drive continues to boot, but the NVME does not. Any suggestions on how to get the NVME to boot would be greatly appreciated.

Why Clone NVMe SSD Won't Boot

Are you also struggling with the same situation mentioned above? This problem may occur for many potential reasons. Some of the common ones are:

  • Unstable or incorrect disk connection;
  • Failed SATA to NVMe cloning process;
  • The cloning process is corrupted or interrupted;
  • The bootable sectors are not cloned to NVMe SSD;
  • The new cloned NVMe is not set as the boot drive;
  • Incompatible BIOS boot mode;
  • MBR and GPT conflict.

Don't worry; we will provide 7 solutions in the next part so you can resolve the issue effectively. Try them one by one.

Method 1. Install NVMe SSD Correctly and Properly

Check if the NVMe SSD is properly installed in the M.2 slot, which is very easy to find on a desktop. If you use a laptop, the location will vary, typically under the bottom panel or the keyboard.

Make sure it is installed correctly and your computer can recognize it.

Method 2. Change Boot Order in BIOS

Another possibility is that you didn't boot from the cloned NVMe SSD if you simultaneously kept the original SATA disk and new NVMe SSD on your computer. In this case, you can change the boot disk in BIOS settings to make it boot from the NVMe disk. 

  • Shut down your PC, restart it, and press F2.F8/F12/Del key to enter BIOS settings.
  • Locate the Boot tab and select the NVMe SSD as the boot drive.
  • Save the changes and exit BIOS.
  • Restart your computer, wait patiently, and check if it can boot up from cloned SSD.

Method 3. Set BIOS Boot Mode to UEFI or Legacy

MBR and GPT conflict will also cause a failing boot. If you clone the GPT disk to MBR SSD or clone MBR to GPT, you must change the boot mode from UEFI to Legacy or swap from Legacy to UEFI.

  • Restart your computer and press F2/F8/F12/Del key to enter BIOS settings.
  • Move your mouse under the Boot tab, click UEFI/BIOS Boot Mode option, and change it to legacy or UEFI.
  • Press the F10 key to save the setting and exit BIOS.
  • Restart your PC and check if the cloned SSD is bootable.

🎨Note: There are situations when your computer only supports MRB or only supports GPT. You need to convert MBR to GPT or vice versa to make your SSD bootable. 

Method 4. Set System Partition as Active Partition

The system partition should be set as the active partition. If not, your computer won't boot from the cloned SSD successfully. You can resolve this issue using the following steps. To use this way, you need to download third-party software EaseUS Partition Manager in the WinPE environment.

  • Restart your computer - Enter the BIOS by pressing F2/F8/F12/Del - Set your PC to boot from the EaseUS bootable disk - Restart the computer.
  • Set SSD system drive as active with the steps and video.

Step 1. Run EaseUS partition manager software. On the disk map, right-click the target partition and choose "Advanced".

Step 2. Then, select "Set Active" from the drop-down menu. Click "Yes".  And choose "Execute 1 Task(s)" and click "Apply".

  • Restart your computer - Enter the BIOS by pressing F2/F8/F12/Del - Set your PC to boot from the cloned SSD - Restart the computer.

Method 5. Perform Bootre.exe Tool

Bootrec.exe is a utility for updating the master boot record code, partition boot sector code, and BCD (boot configuration data). You can use this Windows Command Prompt to solve 'Clone SATA to NVMe won't boot' issue.

  • Prepare a Windows installation disc and boot your computer from it.
  • Select Troubleshoot - Advanced Options - Command Prompt.
  • Type the bootrec.exe command in the pop-up command prompt to launch this tool and fix the error.
  • bootrec.exe /fixmbr
  • bootrec.exe /fixboot
  • bootrec.exe /scanos
  • bootrec.exe /rebuildbcd

Clone SATA to NVMe Won't Boot FAQs

1. Why is NVMe drive not showing in boot?

If your NVMe drives not showing in the boot setting, it is possible that you have not configured the BIOS settings, the disk is not connected stably, your disk is not updated, the drive letter is missing, etc. 

2. Is UEFI required for NVMe?

Yes, only systems that support UEFI can boot from an NVMe PCIe SSD. UEFI is a type of system firmware that aims to improve legacy BIOS and standardize system processes such as booting, driver loading, and so on. Booting the operating system installer in UEFI mode is critical.

3. Do I need to format an SSD before cloning?

It is not necessary to format the SSD before cloning because the cloning process will erase all data on the target disk. Formatting an SSD is also an action to delete all data on it and recreate a new file system.
