NVMe Boot Drive Question

Is there a way to Install a different version of Windows to another drive if the computer has a NVMe drive as the boot drive? In the past I use to unplug the C: drive until after I installed the second OS. Then I would use Easy BCD to setup the dual boot. The one time I didn't Windows moved the boot info to the wrong drive. I'm only asking this in case I ever decide to dual boot Windows 11 with my OEM version of Windows 10.

This is how it went for me. I had installed an NVMe drive that was kept empty as I wanted to go ahead and set-up a dual boot with Win 11. So, I cloned my c: boot drive (internal SSD) to the NVMe and once everything was working properly with Win 10 I made sure to have a back-up on a removable SSD which I unplugged. I then booted in to Win 10, mounted the Win 11 ISO, and installed it on the internal SSD. Luckily this worked and I have not had any issues, as of yet. I was able to install both Win 11 updates without any issues and again, everything works as it should. Some posters have experienced difficulties with having a dual boot set-up this way, some have not. I guess it's a bit of a crap shoot. I was willing to take the risk even after having problems trying to dual boot Win 8 and Win 10 when it was in beta. I'm sure some other members will comment on their experiences.

It is possible only if you take out the one installed disk and install on a different drive.
Otherwise, once Windows recognises that there is already one version installed on a drive, it installs the bootloader into the same earlier installed windows drive.

I'm afraid that is not true at all. It is entirely possible to install Windows 10 or 11 to a second installed drive, with the first drive still installed in the system, and have system partitions on both drives.

Yes, it is entirely possible.

If I boot into Win 11 I get this:
View attachment 3588

This was installing Win 11 by mounting the ISO in Win 10.
Thanks for the two screen shots, I never noticed my disk management screens were different based on my startup boot.

Cheers,

It may be possible, but my experience is that there is only one EFI partition in any dual-triple set up of windows, from where it boots.

If you let Windows handle it. If you manage the drives yourself, you can easily have multiple EFI partitions. Just use the UEFI to change the boot drive first. Alternately, remove the existing drive so it is not present when you install a new OS.

Dual booting =/= automatically using the same bootloader.

The reason I asked is at one time I use to dual boot Window 10 RTM and Windows 10 Insider builds on two separate drives. I had the Insider installed on a SSD that was in a external slide out drive tray. On one Insider build I did a clean install and forgot to unplug my C: drive and the boot loader got moved to the removable drive. I'm thinking about dual booting Windows 11 and Windows 10 but I don't want to mess up the boot partition.

I found a program, DiskGenius, that allowed me to move the boot position under UEFI. Still playing around with it, and am being overly cousious, as one can delete multiple partitions with it. So far I have changed boot to one of three drives, one SSD and two M.2 drives. Maybe someone has gotten further with this program.

I had to go through heck and high water to get the boot partition back on the C drive. For whatever reason nothing worked. Even Macrium couldn't fix it. I finally made a Macrium image of just my C: drive partition. Then I did a clean install of Windows 10. After that I restored the original drive C: image over the new C: drive partition.

What I do is this to flexibly dual boot.

1) install second instance in Hyper-V initially as gen2. That way the Hyper-V VHD has all the boot and recovery partitions

2) Shutdown Hyper-V and mount VHD as a drive.

3) Clone vhd drive to physical second drive.

4) Note drive for windows on second drive (say E)

5) create boot entry on first drive EFI from admin command prompt.

bcdboot E:\windows /p /d

6) Reboot pc and boot into second drive.

7) repeat steps 4 and 5 making boot entry into 2nd drives EFI partition.

8) change boot order in bios to boot from whichever drive you want to normally boot first.

The beauty of this is either drive can be set as the primary boot drive, but you can select the other without needing to go to bios.

Also, more importantly, if you remove a drive, the other one will still boot. You can the remove boot entry for removed drive using MS config.

The way that I set up dual booting on a second drive is to manually create the EFI System or System Reserved partition and a partition for the OS. Then use dism /apply-image to apply the OS image to the OS partition, bcdboot command to write the boot files to the system partition. Setting up the partitions takes less than five minutes and applying the image is the standard time that Windows setup would take to do it.

Would it work using Macrium? Install the new drive in the PC. Boot to the Macrium recovery drive and restore an image to the new drive. That's just simply put but any reason that it might not work?

Would it work using Macrium? Install the new drive in the PC. Boot to the Macrium recovery drive and restore an image to the new drive. That's just simply put but any reason that it might not work?
I didn't think about that. It may just work. I could try restoring the Windows 10 image to a partition I make on my SSD drive. Then I could use Easy BCD to to put the boot entry on my C: drive. I just don't want to mess up my computer being able to boot into Windows 11 if for what ever reason I decide to remove my SSD. Been there and done that and lucky me it turned into a headache.

I have also considering the suggestion that jimbo45 made in another thread about using Rufus to make a Windows To Go USB drive. My computer did come with Windows 10 Pro.
