"We couldn`t create a new partition or locate an existing one."

Try this:

Before you get to that message, press SHIFT + F10 to open a command prompt.

Run diskpart.
At the diskpart prompt, run these commands:

list disk

At this point you should see the SSD as disk 0. If it has another disk number, use that number rather than "0" in the next command.

select disk 0
clean
exit (to exit from diskpart)
exit (to exit from the command prompt)





That should clear the contents of the disk. The entire disk space should then show up in Windows setup as "Unallocated Space" as in the screenshot below.

 

Update KB4550961 couldn´t be installed

Hi! I´ve tried hard to install KB 4550961 unsuccessfully. Even run this or that in order to correct whatever the problem might be.

However, after restart it appears “Updates couldn’t be installed” on the screen. Running Scannow and Restorehealth as Administrator didn´t
work either.

I´ve also gone step by step thru “Fix Windows Update errors” steps 1 to 5. I´m reluctant to follow Step 6 Reset or Reinstall Windows –
Refresh is not included - because I´m afraid I might loss some stuff important, though I created a restoration point and a USB recovery drive, just in case.
