Just before i nuke this disk and put Debian on it, it might be worth asking: i suspect i've fallen foul of the latest Windows Update problems. Windows Update is thouroughly broken and sfc /scannow shows all sorts of errors. So ... as a nuclear option i decided to try two different tools: MediaCreationTool.exe and RefereshWindowsTool.exe in order to install a fresh copy of Win 10.
Both went into a cycle of downloading a large image (c 4GB - i've no idea where it was put) and then telling me that setup failed (see below)
Is it possible to get a fresh copy of Windows as i was promised without the buggy extra software i seem to be getting? I just want an ISO with Win10 on it of a recent vintage.
