Win 11 Boot And Upgrade FiX KiT (v5.1f Released!!!)

Is it possible to install Windows 11 to a single NTFS partition (instead of three) in Legacy BIOS^/MBR only systems?

 

Absolutely
Just partition the whole disk as one partition first and choose to install Windows there

Press Shift-F10 during setup and type diskmgmt.msc + ENTER
There you can create one big partition

 

This used to work with Windows 10, but it does not work with Windows 11. I did not try installing Windows 11 after running with this script and I want to make sure that it works.

 

This still works
But you have to boot from Windows-PE

 

I did not have to boot from Windows-PE in Windows 10, so why do I have to in Windows 11? Anyway, if I use Win 11 Boot And Upgrade FiX KiT to modify a Windows 11 ISO, will installation work on a single MBR partition?

@Enthousiast,

Thanks for the tweaks 2b fix. With offline integration (directly in install.wim) it worked great when proceeding with Inplace Upgrade.

EDIT: Tested with 24H2 26100.1591 build

 

So does Win 11 Boot kit make a modified ISO that you then have to make install media out of or what? And if so, what program do you suggest to make the install flash with? If I am totally wrong about this please point me to the written procedure of what to do.

 

1. Get a Windows 11 adequate ISO image
2. Apply the kit
3. Use te generated ISo to install Windows 11 by creating a boot device or by mounting the ISO and execute setup.exe.

 

For myself I just use IoT 11, but I have a business client that this would apply to and my question is would you have the burden of doing this at least every 2 years, because your hardware is still
non-compliant and will still never auto version upgrade?

 

If i were a business client, i would only use official harware and software.

 

I went with the 5.0 and it was a nightmare.. I kept downloading from mega and I was unable to do anything...lol.. Someone else had that issue a few pages back.. boom... used another link and its installing windows right now. Thank you guys!!

 

Just check the hash of downloaded file is the same as provided in the OP and all will be fine

@Enthousiast: I have to get this off my chest, your tool is great. I've been using it at least twice a month since it started and I haven't had any problems with new installations or upgrades using the default settings. Thank you very much for your great tool.
