Thanks. I just nuke the hard drive down to one big partition, then create a C: Partition with 75 GB. After I get WIndows 10 reinstalled, I use Minitool Partition Wizard to create additional partitions. I NEVER store data on the Operating System partition, including downloads, program installs, or anything I don't want to lose if the OS partition is corrupted. You can save many hours reinstalling an OS partition only. And if you periodically clone the OS partition you can be back up and running in very short order without having to start from Ground Zero.
I then nuke he BIOS of any boot loaders other than the disk system. I have found that some used computers will still have embedded BIOS loaders which try to point to a company's network servers, asset tracking, etc.
Then I use RUFUS to boot from a USB and install whatever flavor of Windows 10 needed, and go get a beer. I the case of Dell computers, once you get the network connection working, you can go to Dell and download the Windows 10 version shipped with the particular computer, including drivers and stuff. Then you can let Windows update to the latest flavor of Windows.
Now comes the fun part: Deleting or uninstalling the baked in Windows crap you don't want, disable telemetry, updating, install your brand of browser and setting up the computer the way you want it, including other partitions and sundry other tools such as Revo Uninstaller, Search Everything from Voidtools, and, of course, FLoatLED, the disk activity indicator.
I then use an app to transfer installed apps from an app cloner. Saves a lot of time.
As I said, I genuinely tried to give Windows 11 a chance, but it is just too annoyingly similar to MAC OS, missing things I use, and dammit, I have been using he taskbar a the top of the screen for years and I'm too old to learn where to find things again.
It's kind of like when we got married 53 years ago. Our second fight. She agreed to NEVER "clean up" and rearrange MY workbench, and I agreed not to smoke cigars in her car or rearrange HER kitchen. And of course, put the lid down on the throne. That, of course was the FIRST flight. First night as well, IIRC...
Thanks for the info. Their method works, but I like mine, and I detest those computer generated voiceovers.
