Windows 10 upgrading tips

Windows 10 upgrading tips

I don't think anyone really tested upgrading. I finally got windows 7 to upgrade.
Windows 10 has to have an available partition for the system reserve for upgrading at least 450 MB or a current system reserve partition already installed.

It seems that windows 10 requires the previous operating system to be installed on first partition, still testing that method out, which may cause problem with some OEM partitions.

Don't upgrade from a usb stick, that could also be an issue with windows 10 as well. I made another partition, copied the windows 10 install files from there, then did the upgrade from that folder. Windows created a system reserve partition. If you already have a system reserve, I think windows 10 will use that instead but increase the size to 450 mb if you can.

As a test, I did an inplace-upgrade from Win8.1 to Win10TP when it first came out -- and it did not create any new partitions. It saved the Win8 stuff off into a windows.old folder, which I eventually removed.

But that upgrade eventually had so many problems that I scrapped it and did a clean install of Win10TP with one of the later builds. So, I don't have that around to experiment with it anymore.

That is alright no need to test.


All,

When I did a clean install of windows 7 , I did it so windows 7 wouldn't create the system reserve partition. I forgot to mentioned I upgraded form windows 7 64 bit version to windows 10 64 bit version.


This is a non-gpt disk.

Here is what I did
Download windows 10 preview 64 bit
Create bootable iso image using windows 7 dvd/usb creator program.
Shrunk windows 7 partition using windows 10 disk manager
Created a new ntfs partition windows 10 disk manager.
Created a install folder on new ntfs partition.
Copied the install files from the usb drive to the install folder
Removed USB drives
Rebooted
I didn't disable MSE
Keep it connected to the internet
Started setup from the folder on the new ntfs partition
It upgraded without issues but I had to download a new graphics driver from the internet via driver update.
Windows 10 upgrade created a system reserve partition.

Haven't tried to see if I could do a clean install of windows 7 on partition 3. Which might be a possibile. I am not sure if I want to go to the much work tell I know for sure Microsoft life cycle policy and whether or not windows will become subscription based. If the Os becomes subscription based, Microsoft and their oems can forgot me as a customer. Also, locking the computer to one operating will be an issue with me. I would possibly want to dual boot with windows 7.

I did another non upgrade testing, if done right it does do a clean install on partition 2 and for some reason no system reserve partition was created. This was from a usb stick. Installed Windows 10 64 bit.
