Shawn, any chance you could change the name of this tutorial a wee bit? Make it
Custom (Parallel) Install Windows 10
I never think of this as a custom install. To me it's always been a parallel install, alongside the existing install. I always have trouble finding this until I remember to use the Search Tutorials under the Forum tab.
The end result appears like a reset save files but with a Windows 10 iso.
Another name could be reset save files equivalent.
Hey Rich,
You may be thinking of the repair install method below instead for a parallel type install since it would use the same version/build as what's currently installed without losing anything.
Repair Install Windows 10 with an In-place Upgrade
The custom install method would be more for doing a clean install of whatever version/build instead, but have a copy of the old installation in the Windows.old folder unlike if you did a full clean install at boot.
Yeah, I did used "Custom" since it was the option you would select during the Windows Setup process.
Yup, that's the one. I don't know why I didn't see that when I searched as it popped up at #3 just now.
Thanks Shawn.
No, that requires you to be able to boot into Win 10. I really did mean a Custom Install but without deleting or formatting anything, just doing a parallel install to the C: partition along side the existing partition, which then gets moved into C:\Windows.old.

There are many threads with Windows 7 upgrade failure troubleshooting.
Some troubleshooting steps may not fix the failure to upgrade 7 to 10.
Or some end users may prefer alternatives to troubleshooting.
Please consider another tutorial or updating this tutorial to include Windows 7 and 8:

Just found this tutorial from 2009:
Custom Install Windows 7 - Windows 7 Help Forums
Hello @zbook,
Do you mean one to upgrade from W7?
Upgrade to Windows 10 from Windows 7 for Free
That's similar to custom install windows 10.........thanks
The tutorial has images for each BIOS and UEFI.
There were no comments on UEFI hybrid (with CSM).
When a custom install was attempted in UEFI hybrid it failed displaying a yellow triangle with exclamation mark:
Windows cannot be installed on this disk.
The selected disk is of the GPT partition style.
Please consider comments on the need to modify CSM: UEFI hybrid (with CSM) to UEFI native (without CSM)
