Unknown Space - Not System Restore Files

I've had this issue on every Windows 7 and onwards PC I've owned and it's the dreaded "unknown" space being used that gets bigger and bigger until it becomes noticeable. The issue is this time is it doesn't seem like the easy delete the system restore files option within Computer > System > System Protection





Here's the System Protection settings pages plus the command "VSSAdmin list shadowstorage" run as administrator which confirms no space is being used by shadow copies.









Something that is probably worth saying is that I recently moved from a HDD to a SSD by cloning the original HDD. Since then Programs and Features has not been displaying the file sizes of programs correctly with a number of them being exactly 6.51GB and others despite being 20+GB games (Project Cars) showing as having no file size at all!







This doesn't match the file sizes that Steam is reporting:





Anyone got any ideas on what this could be or a way of locating this unknown space?

Thanks.

 

Unknown file system grub rescue

Hi,

I have the same error as described here: Error unknown file system grub rescue

But the resolution steps did not help.

I have a dual-boot system (win10 + ubuntu).

When I tried the repair procedure I got "windows cannot fix your issue" with two options - troubleshoot again (which doesn't do anything different) or shut down.

I'm unable to do anything from here.

Any suggestions would be welcome!

BR,

Milena

 

File System: Unknown

format it and set the file system to FAT?
