My Samsung Laptop Model NP54073C-A02AU - DOES NOT BOOT. (no dvd)
It was working for some months on Windows 8 and crashed during an attempt to upgrade.
Windows 8 was pre-installed. The windows 8 sticker does not have a product key.
Samsung support say I have to contact Microsoft for the product key.
My plan was to download the windows 8.1 iso image; create a USB bootable stick; then try and install onto the Samsung.
I have had difficulty downloading and Im not sure this the best process anyway.
Ideally I would like to access the hard disk that does not boot and try and recover the product key.
Update: although windows 8 does not boot... I am able to get access to the recovery and tools options via the Function and F1 key.
I can use the DOS prompt option.
I cannot use the recovery option as nothing had been saved previously.
The "Refresh your PC" option appears to be working as dots are circling and
"Please wait" signals some hope.
I will leave this running overnight.
Please advise what my options if the PC does not reboot windows 8
