What is Windows 11 like for dual booting and sharing other drives with Win10?

I currently have a windows 10 Pro machine that is setup just the way I like, and want to install Windows 11 pro on another separate SSD drive, so both windows will have access to another third SSD drive. For example, I might do photo editing in Win10 that works with the photos on drive 3, and then in Windows 11 I might do video editing that uses files stored on drive 3.
Can this kind of thing be done without problems? Will I get issues like 'drive access denied' when trying to use drive 3 on either win10 or win11?
Any other tips?

Thanks

Give Everyone group a full permission to drive 3 you will be okay if not we deal with the permissions when needs to be.

Thanks, I'm not sure what this means exactly, is there a basic tutorial you can point to?

Open the Command Prompt with admin privileges and execute the below command for your storage drive.


Replace X: drive letter with drive 3 drive letter.

This command gives full permission to Everyone group on drive 3.

It's been a long time since I use to dual boot but I don't remember ever having to change any permissions. The only thing I remember ever having to do was to click OK when I wanted to access a user folder on the other drive.

Yeah - I multi boot a lot on my backup laptop, and I have never needed to change permissions to see other drives.

I advise @OP just sets up dual boot first first before messing around with permissions as earlier posters state.

It will probably just work fine.

Both Windows 10 and 11 should have full access to the third drive without any issues because they access it locally, not from the network. I would assign it the same drive letter, say E: in both Windows for convenience. In the rare case that you need to give Everyone full access, right-click on the drive and select Properties, Security. I don't have access to my computer right now to guide you more, but you open Advanced settings and add Everyone to the list of users. Then change permissions from read only to full access on Everyone user.

I actually did exactly what you're thinking of doing. I installed Win 11 to a second drive shortly after it came out to "check it out".
My Win 10 Library folders were already moved to a third drive and both OS's could see and use all the Library folders without any
permission issues and all of my other data drives as well. I now dual boot Win 11 23H2 / 24H2 with the same setup.

I have loads of Different Windows versions available on boot plus Linux too -- even easier if you use vhdx physical files but not necessary. Create one single EFI partition, then either loads of separate physical partitions or a single one if using vhdx files to accomodate all of them and it's fine (install the bootloader for each OS to the EFI partition). If running Linux too then install that separately first -- install the Linux bootloader to the EFI partition.

E.G :



The overhead of using vhdx files is negligeable these days -- perhaps a few microsecs longer when booting !!
If you have Linux installed and want to boot simply "Choose other options" from the boot menu -->Use a device and then it will find the Linux Grub / Systemd boot loader and boot that, You can have as many OS'es Windows or otherwise as the EFI partition will require -- if using Linux make it around 500Mb (to load to /boot/efi) otherwise 100Mb is big enough for even 5 or 6 Windows systems.

I like the idea of different OS'es -- it's much easier for example when you want different languages and different applications -- just boot the appropriate system rather than change and re-boot an existing OS. If these are all on the same machine Activation is kept so no prob with that one. My typical Windows OS is around 25 GB - I usually make around 45 GB to allow for updates etc. User data I keep on different partitions, disks or even the cloud. Always best to keep User data separate from the OS.
