Windows 11 is now available to Windows Insiders on the DEV channel. As of 28th June 2021
If you want to try it, I suggest you only use either a spare PC like I have, or a spare SSD in your main system. I would not replace your main Windows 10 install with this development release.
Before you even begin. Download, install and run the PC Health Check application from Microsoft to check if your hardware meets the requirements for Windows 11. If it doesn’t meet the Windows 11 hardware requirements, don’t even try as you wont get it.
You will require a TPM 2.0 module on your CPU/Motherboard to use it, and will have to enable Intel PTT or if you’re using an AMD RyZen CPU then enable fTPM.
To use TPM you will have to enable it your UEFI/BIOS, and also enable Secure Boot in the BIOS, remembering to add the Factory Keys if you haven’t used TPM before.
You may also have to disable CSM (Compatibility System Module) in your BIOS to get the machine to boot.
The drive your going to install Windows 11 to, must have a GPT partition, an MBR partition is not suitable.
The following screenshots are taken from my own spare PC running the official Windows 11 insiders preview.
