Windows 10 Can't reinstall Windows after using laptop as a Chromebook

[Kevin Heath]

I have an old laptop that I thought I'd try and speed up by using it as a Chromebook, however, I want to go back to Windows.

I created a bootable USB Windows 10 drive and booted from that. I have run Win10 on this laptop before.

When I try to install, there are now 27 partitions on the drive and the main one with some 450GB reported gives the error "not enough space to instal Windows".

I tried formatting that part of the drive and that hasn't worked.

How can I get my drive back into a condition where I can reinstal windows?

Choose the advanced option and delete all the partitions, then install
