Question I cloned my system drive(SSD) to another drive(also SSD) and how to make system boot from the new drive?

Power down the system and physically remove the second Drive or at least remove power to it booed up and see if it boots on your main SSD

That new drive does not look right. I don’t know what you did but this is not correct you shouldn’t be seeing those SSDs like that in there to full they shouldn’t be red

okay, I will give it a try. It is full, because Easeus todo has made partition of an exact size of previous drive.

If it still fails, redo the clone operation.


-----------------------------
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
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
If you are cloning from a SATA drive to PCIe/NVMe, 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

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 specifiy the resulting partition size, to even include the whole thing

Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
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.

So I got It working now. After trying to choose my drive drive as first to boot in bios it wouldn't work, so i physically disconnected my old drive and PC succesfully booted from the new one. I merged new disk partition with unalocated space and everything is perfectly fine. But my question is: can I reatach old drive without any problems that PC will boot again from it. I want to make sure, as I don't want to mess it up.

This is when you test it several times, verify in the boot order that the new drive is first.
Don't 'delete' anything until you are SURE it works from the new drive.
