Windows 10: How can I recover Windows10 after BSOD when there is no disk space?

My computer won't boot after an automatic Windows10 update; it gives a BSOD repeatedly. I can boot it with an USB stick created on another computer but I cannot reinstall Windows as there is not enough free space on the disk.

a. Can I rename the folder Windows.old to Windows and recover the old installtion?

b. Can I just delete parts of Windows.old to make space?

c. Can I delete parts of the folder Windows to make space?

I can see that in the long run I shall have to buy a new computer but it would help if I could get this one running again.

Thanks

:)
