Bootcamp Failing to Install Windows 10 on Macbook Pro A1990

Hello,

Recently I acquired a 2018 Macbook Pro A1990, with a i7 2,2, 16 GB RAM, and 256 GB HDD. I upgraded it to Sequoia, and now decided to try having a Windows as a second OS.

Aaaand here starts my problem. Bootcamp creates the partition, reboots the computer, boots the Windows installer and after accepting the license it goes to installation screen "Copying files" stays at 0% and the installation fails saying that "Windows cannot locate the disk and partition specified in the unattend answer file's <ImageInstall> setting. Make sure the setting references a valid partition and restart the installation". I tried many different iso's - older ones and current one. I then tried many tutorials. Created bootable Windows USB, with bombardier and with drivers gotten from Boot Assistant. Windows 11 bootable USB gets to 77% and tries to restart, and says "Windows 11 installation failed." Literally nothing works.

Anyone can help?

MacBook Pro 15″, macOS 15.3

The biggest part of your problem is that Windows 11 isn't fully supported by Bootcamp. According to this website ti requires additional configuration. The linked article also suggests the best way to install Windows 11 is with a virtual machine. i.e. Parallels or Fusion

I tried Windows 10 with and without bootcamp. I tried Windows 11 on a bootable USB as bootcamp won’t even let you begin the process with Win11 iso. Have you even tried installing Windows on your Mac before posting your reply? My biggest problem is that Bootcamp is not working as it should and I am left without answers.
