Here's the story, I have been asked to look at a Toshiba satellite laptop that refuses to boot. The reason is the hd is toast. It will not boot, just sits there clicking. Tried it in another laptop, result is the same. Recovery software can see some data so it looks like badly damaged data corruption.. There are about 5 partitions on the disk. The ONLY thing I have managed to do is copy some music files and extract the activation key using magic key finder from the hive file in sys32/config. So, its bolloxed.. So, moving on. New HD fitted but the guy who has asked me to repair it never created recovery disks. So after much reading (done nothing with windows 8 as I detest it) I have learned I can download an iso from MS, BUT when I input the product key, it tells me its invalid. Which I assume is because its OEM. So, question is this, what can I do. Seems a bit unfair to have to buy another copy of windows 8. Can i turn a retail into oem? can I obtain a toshiba oem set up disk? Any input folks?????
