PC Bios shows as 240 GB
Brand New drive
Cloned using Clonezilla which simply uses standard partitioning software to copy and partition the drive.
Drive shows as a basic drive, with a few partitions as shown in that screenshot. The free space which should be on there does not show up for some reason.
I can try imaging the drive and reformatting but this is strange.
Apparently you cloned it in some full disk block to block way (dd-ish), instead of creating a suitable GPT and clone the filesystems one by one with partclone/ntfsclone instead (and resize "C:" with ntfsresize).
You can at best see extra space at the end of the disk this way, if the drive has MBR/MSDOS Partition Table. In your case it looks like it's GPT, and with the way you do the cloning, I doubt that CloneZilla would put the backup GPT at the end of the new drive instead of right after the last partition (this is the right thing to do anyway). This could be the reason preventing Windows from showing you the extra space in any form.
If you have a Linux live medium, try to check the new disk with fdisk/gdisk and create a new partition table and partition (WITHOUT actually writing to the disk) to see if you can utilize the maximum size. If you can, then my theory is probably right.
