missing primary boot drive
Primary boot drive failed in win10. Doesn't appear when using diskpart list volumes. 2nd drive (d) appears as C: drive. Believe partitions damaged or lost and if fixed could see the original boot disk C: again. Booted from a USB to get CMd line. But need instructions how to launch disk MGMT.msc. commands I would normally use in powershell or on server not working on win 10 pro on laptop. It is difficult to find instructions on how to get control panel, disk mgt, network etc launched from CMD.
