Is it possible to run Windows 11 on a 2010 Mac Pro? I have been using OpenCore, but I was told that Windows will try to write over the BootROM. Any help would be greatly appreciated.

No problem at all. Create an install USB from ISO using Rufus (to disable TPM, 5,1 does not have this chip), start installation from OC bootpicker. Make sure you install to a different physical disk, in order to not destroy your MacOS.

It is possible to run it in Parralels. Macs lack those hw features i always forget their names, Parallels emulates it.

I have been running W11 on MBP in parallels for around 3 months, without any issues.

How do you proceed after W11 is installed? Do you install Bootcamp? I mean - is Bootcamp needed? Mine gives blue screen after bootcamp install…

I don’t. No bootcamp drivers at all, it’s a regular PC.

I was able to install bootcamp 6.1, but with OC bootpicker, yeah, it's probably not needed.

Having recently reformatted my Windows drive and installed a fresh copy of Windows 11 Pro, I will reiterate what's been said in this thread:

If you are using OpenCore, you DO NOT need bootcamp or brigadier or parallels.

Follow the method outlined by @hwojtek above and you will be up and running in no time.

Hi all,
in which format must be formatted the target volume to receive Windows, while installing it from a USB drive created with Unetbootin (Universal Netboot Installer) ?
Format in MBR ?
Thx

Here you go <-- In addition to this, read @hwojtek's post above, the second in this thread.

Windows 11 needs GPT UEFI, not MBR.
