Back in June, I added a linux partition to my old Windows 7 thinkpad.
The machine was still, and remained, on Windows 7 as a backup machine to my documentation work of Dow's Pharmacy.
However six months on, we're still in a hiatus because of the ongoing covid-19 emergency, and I'd reached the point where I really couldn't delay upgrading the Windows 7 partition any longer.
So yesterday I upgraded it.
I was a bit apprehensive about doing so as I could imagine various scenarios where the Windows 10 upgrade process and the linux boot manager had an argument, but I needed have worried, it just worked.
It's an open secret that in most cases Microsoft will still allow you to update from Windows 7 to Windows 10 for free providing you have a legitimate Windows 7 install.
I did two things outside of the standard upgrade procedure before starting:
- I used Grub Customizer to make Windows the default operating system to boot, so that when the system rebooted during the upgrade process it wouldn't need manual intervention to select Windows.
- I used the Magical Jelly Bean KeyFinder (seriously) to find my Windows 7 license key in the registry, as some comments I'd read suggested that occasionally the upgrade process requested that you re enter the license key. As I'd bought the machine second hand, the Microsoft license key sticker on the base had of course disappeared.
