Question HELP: Need to change boot drive

Jul 15, 2022
I have recently decided to clone my os from my old 250 gb HDD to my new 2 tb SSD. After I successfully cloned the os I restarted my computer to change the boot order in bios but I found the SSD was not listed in the boot priority list. The weird thing is it is listed on the storage tab in my bios. I have an MSI x570 (MS-7C37) motherboard. Can anyone help me change the boot order to boot from SSD?

You did it completely wrong.

After the clone, assuming it was successful....

You needed to power OFF, physically disconnect the old drive, and allow the system to try to boot up from only the new drive.
That is a reqquired but rarely documented step, and often missed.

This may need recloning.

Specific steps for a successful clone operation:
Verify the actual used space on the current drive is significantly below the size of the new SSD
Both drives must be the same partitioning scheme, either MBR or GPT
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
If you are cloning from a SATA drive to PCIe/NVMe, you may need to install the relevant driver for this new NVMe/PCIe drive.
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive

[Ignore this section if using the SDM. It does this automatically]
If you are going from a smaller drive to a larger, by default, the target partition size will be the same as the Source. You probably don't want that
You can manipulate the size of the partitions on the target (larger)drive
Click on "Cloned Partition Properties", and you can specify the resulting partition size, to even include the whole thing
[/end ignore]

Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD. This is not optional.
This is to allow the system to try to boot from ONLY the SSD

(swapping cables is irrelevant with NVMe drives, but DO disconnect the old drive for this next part)
Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe all partitions on it.
This will probably require the commandline diskpart function, and the clean command.

Ask questions if anything is unclear.
