Manjaro / Windows 10 Question – Installation & Boot
Support for Windows is off-topic and therefore of no concern to Manjaro Forum and thus there’s no good answer to the question as theres is too many unknowns.
Theoretically – if your system is equipped with two disks – then maybe it can be done – I would recommend to disconnect the disk with Manjaro – to avoid accidents.
If your current system is MBR you cannot install Windows without destroying Manjaro.
If your current system is GPT/EFI you may have a theoretical chance of success – again – it is unsupported – and you may loose ability to boot Manjaro – but – you have a theoretical option to boot a live Manjaro then setup grub config for os-proper and restore the bootloader gaining access to both Manjaro and Windows from grub.
There is simply too many theoreticals – sorry – we cannot help you.
The closet thing we have on Windows is how to successfully install Manjaro in tandem with an existing Windows.
