I didn’t want to wait for the Windows 10 update to be pushed to my development machine so I opted to use the Media Creation Tool to update Windows manually. At least I tried to do so.
My first problem was receiving the very useful error: “Something happened”. Having downloaded the media creation tool, I ran the program and selected update this machine, only to produce the noted error. Microsoft’s programmers might as well have indicated that “nothing happened” because, essentially, nothing did.
I tried again to run the media creation tool thinking that, this time, I would download the ISO file and create a bootable USB drive. I couldn’t even do this without a something-happened error! However, this time it gave me a 0x800… error code that I could at least run through Google.
The fixes suggested on the web included running the media creation tool as an administrator which didn’t work, and running it under an administrator’s account – which did! I don’t know why MS in its wisdom couldn’t do better than “something happened” in this scenario but, when running as an administrator, the update to Windows 10 went smoothly. Well, at least as smoothly as possible, given the multiple reboots required to make the process continue to completion.
Initially, I was congratulating myself since, not only was my machine now running Windows 10, but the grub menu remained intact and I could also boot into Linux Mint.
However, such success was short lived. I quickly discovered that my dedicated data partition (DataDisk in Linux and Drive D: in Windows) wasn’t being mounted automatically when booting into Mint. Or, at least, it wasn’t being mounted at the expected mount point.
Running the blkid command revealed that DataDisk had changed from /dev/sda6 to /dev/sda7 as a result of the Windows 10 update. This was quickly rectified by editing the etc/fstab file to use the new partition designator.
A check on the pre- and post-update partition layout showed that the update to Windows 10 had added a 450 MB partition (that was unused) between Partition 5 (the Windows C: drive) and (the now) Partition 7 (the Windows D: drive – and the Linux DataDisk!)
So, two “tricks” to perhaps bear in mind if updating to Windows 10 on a dual-boot Windows/Linux system – run the update under an admin account, and watch those disk partitions.
