Hi, I currently have a Dell notebook with two physical SSD's inside of 1tb each as shown in the attached screenshot. I currently have Windows 10 installed in the C drive (physical SSD 1). I would like to install Windows 11 in the D drive (physical drive 2) and upon booting to be given the choice of which OS to use. Is this possible? and if so, how? Thanks

Thanks jaree, I read the instructions and they are pretty clear. Two questions arise:
1) Once I complete all those steps , then each time I reboot I will be prompted to choose which OS to boot from?
2) If in the future I want to revert back to a single boot Windows 10 PC, how can I "uninstall" windows 11/dual boot?

It's fun but it is not highly recommended if you have no experience with it. One update (on either OS) can mess up the boot managers and give you all sorts of problem. Never do it on your main laptop if that is the only one you got. Maybe a VM will satisfy your Win 11 curiosity.

Yep, 1 drive for you OS, and 1 drive for your files, and even a few images.

Hi there
Easy

install on VHDX ("Physical Virtual hard drives" -- All these on the same HDD with a single EFI boot file and a single 128 MSR partition. These also include a Linux system and a W2K22 Server system. This lot are running entirely from an external SSD !!!!

Hi Jimbo, what about performance? Are VHDX slower than a regular install?
