Need help with Cloned Drive

I don't really know a lot about computers etc. i have managed to build my pc over time and figure things out via youtube.


I recently purchased a 1TB NVMe M.2 drive that i would like to boot windows from

I have done some research, found a video on how to clone the drive. Followed the video and everything is cloned successfully.

However. When i go into my BIOS and choose UEFI for the new drive i purchased, when it boots. It goes directly to the Windows Setup as if it doesn't have any OS on the drive yet.

Does this make sense to anyone or have i explained it poorly

Thank you for your help in advance, your fellow noob here

Still doing more research. It may seem that the SSD that i cloned over was MBR format and not UEFI. Does this make sense?

I have managed to convert the disk to UEFI, but now there is 730 GB of space unallocated. When i try to format the unallocated space it gives me an error that says.

"The operation did not complete because the media is write-protected"

zhatchett hello and welcome to tenforums,
Please post a screenshot from Disk Management

Also download and run Crystal Disk Info to check drive health.

I prefer to image the original drive to another drive, install the new drive then recover the image to that drive. I use Macrium Reflect for this.

This is one approach that would definitely work and would be the only way to do it if the original drive died and you were fortunate enough to have a recent backup image.

When i try to format the unallocated space

Create a partition first, then format the partition.

Or extend the adjacent partition to incorporate the unallocated space.

If you still get the error message, then try to remove it using cmd prompt
diskpart
lis dis
sel dis (whatever the disk number is)
attributes disk clear readonly
exi

Hi everybody who posted here. I appreciate the help. What i did to fix the issue

Ran command prompt to remove readonly status of my original drive that i wanted to clone, changed it to UEFI (i forgot how i did this to be honest). Then deleted all partitions of my new m.2. Then re-cloned over the drive with the uefi.

This probably doesn't sound right but it worked? It was trying to boot into legacy mode on the m.2 (i think)

zhatchett, Thanks for the update.

Thank you to everyone here. I will definitely be using this forum for pc issues
