I have a Sony Vaio Pro laptop that came preinstalled with Windows 8. I wiped the disk and now I don’t have the original system left any more. For my misfortune, the laptop didn’t have a Windows installation code with it. I didn’t even check that before removing Windows, because until now all the computers I’ve seen have had a code with them, either on a sticker on the bottom of the computer or in the manual.
I read that these computers have the code stored in their BIOS. I copied my Windows 8 installation disc contents to a USB. This disc is burnt from a ISO file that I got when I upgraded my Windows 7 to 8 via the Microsoft tool.
I changed the boot type from legacy to UEFI (Ubuntu didn’t like UEFI) and booted from the stick. It asked me the language and keyboard settings and then it asked to click the install button. Shortly it showed an alert message saying
The product key entered does not match any of the Windows images available for installation. Enter a different product key.
I tried searching with the error message and people suggested to override the key in BIOS by using a pid file, but that’s not possible in my case because I don’t have it.
How should I proceed?
