This computer's hardware may not support booting to this disk. 'Windows cannot be installed to this disk. Update to last time, I tried to run the Windows 10 install disc from the currently installed windows on the HDD (as opposed to straight from boot on DVD) and here, the drive does show up, however I get the error message: Will add that on that sandisk SSD dashboard, it does not recognise my SSD - though I have to reiterate the SSD works perfectly normally while using it as a second drive and can format/partition it without problem. Hi Colif, tried everything you mentioned to no avail.
