[SOLVED] Failed partitioning new M.2 drive


Dec 29, 2016
I bought a Kioxia Exeria G2 1TB. Installed it and went to partition it. I'm currently running a 128GB sata SSD booting Win10 and wanted to clone the sata to the M.2 and then wipe the SSD drive just using it for storage.

I cloned the SSD via Macrium, the disk was then split with the 120GB from the old clone in one partition and the remaining space being unallocated. When trying to create a new partition or extend the current partition it would say error not enough room.
I then clicked shrink partition to see if it would do anything which worked but now I don't know what to do.

I'd like to just restart the whole process but not sure how to remove the healthy partitions, I did try removing them via cmd (admin) but it didn't work.

How can I make it one whole partition and change it to boot from the M.2?
Thanks, could you recommend the best way to clone + make it one whole partition as last time I tried via Macrium it wouldn't let me extend the partition.
Your only issue was, you tried to extend C: partition without having any free space next to it.

Redo your cloning.
Delete recovery partition.
Then extend C: partition.

If you get warned about disk converting to dynamic, then you're doing something wrong. Stop immediately then.

You can change the size of the resulting partition during the clone process.

The middle section here shows how:

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 target 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

Verify the system boots with ONLY the current "C drive" connected.
If not, we have to fix that first.

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.
