For Double / Triple booters this is the best way by far.

Hi folks
Double / triple booting etc can often be a problem especially if you have a non Windows OS and decide to wipe that OS or even one of the Windows OS'es.

I'd recommend - if you have a decent spare SSD device and a SATA->USB3/ USBC type connector. This method depends on creating a fully standard Windows system on the externel device so nothing in the main computer is touched.
What you basically need is :
1) macrium image of a fully running W10 system (latest possible version) or the W10 system itself on THE TARGET MACHINE.
2) Stand alone bootable partition manager
3) W11 running in any sort of VM -- HYPER-V, VMWare, VBOX (if you van get W11 to work -- eluded me I'm afraid) , or KVM/QEMU.
4) Usb thumb drive for booting the macrium iso.

OK here goes
1) Image the VM (FROM WITHIN the VM) and ensure the image is written to a device accessible to Windows.

2) create the Macrium Free stand alone rescue media -- FROM WITHIN THE VM. You need to choose the advance build and select the WINPE version -- choose the one that says best for Win 8.1 / Win 10 not the WINRE version and ensure all device drivers are loaded . You need that when we come to fix the boot on the Real machine !!

3) ensure that the bootable rescue media is available to a bootable USB device - what usually works best here is to (again from WITHIN the VM) to create an iso image in macrium and then use RUFUS to create a bootable USB stick. I've found creating the USB directly via macrium doesn't always work so I'd recommend using the ISO.

4) Take a macrium image and save to storage device.

5) on the target machine ensure macrium thumb device and macrium image are available as well as the external target device for Windows.

6) boot into Macrium and restore the image. You don't need the W10 system or image at this stage yet.

7) do not yet reboot the machine - but still within Macrium choose fix Windows boot problems - I've found by using an image from a VM this invariably works. Attempting similar from a Physical image doesn't work for me - often get BSOD or "OOPS something went wrong at boot time so i'd recommend using the VM image !!).

8) boot the external USB device -- should work - you'll probably get a few messages like getting device ready -- but there's still a bit of work to do.

9) Now boot your stand alone partition manager -- you'll probably want to do this as your VM might only use 40GB of "Virtual disk space" whereas on an external USB device you might want to use the whole device say 128 / 250 GB --these are the best to use for this as they only cost a few dollars each these days. !!!

10) move the recovery partition to the end and expand the C partition.

11) now re-boot the external SSD drive

12) you'll need to update a whole slew of drivers -- so either from the W10 macrium image (yes the W10 one) or an actual Windows internal W10 "C" drive point to directory windows->system32->driverstore

11) via device manager go through each device which needs a driver update or "unknown" device and choose update driver, scan this computer and use the directory in step 12). Ensure the "include subdirectories / folders " box is checked

12) should fix things like video drivers / sound etc etc.

13) activate as normal - in some cases this will activate via Digital License if you created the W11 system via an update from W10.

Have fun and enjoy your "Portable Windows 11 system". For me it actually works better than my Disk based W11 system -- that's because the old laptop still has laptop "spinners" and even via a USB 3 connection any SSD is way faster than those older 2.5 inch spinners - even if they are sata ones.

Cheers

Hi, This what I will do in my system (no more disk space for the imaging stuff),

Requires Windows 10 and 11 install media (as far, my system doesn't meet the requirements to run 11 so I modified my 10 media to add the 11 install.wim)

Because my data on my system is full software, not files (some file will put in my Google Drive (also I have an managed school account if my GDrive is full)), so I will do an clean install. Note I will dual boot my system, 10 and 11 insider.

IMPORTANT: Back up any data if you want to do this, because it will delete all DATA on your system.

1. Restart the system (as far you are booted into Windows)
2. Go to your Boot menu, and select your USB drive.
3. Because I have secure boot enabled, I get a splash screen that the key could not be verified. (because I have an multiboot Ventoy USB that I will use here, and it supports Secure Boot, it will easy to me) Now, I will select the right partition (VTOYEFI), and select the key file, it now boots to my Boot Menu.
4. Select first the Windows 10 media.
5. Do the normal W10 install process, until you on the partition map.
6. Allocate 60GB in Windows 10, 60GB in Windows 11, and the rest is on your data partition.
7. Install Windows 10 in your Windows 10 partition.
8. Complete OOBE, and complete the setup of your system.
9. Restart your system.
10. Go to your boot menu, and select your USB drive.
11. Select now the Windows 11 media.
12. Do step 5.
13. Select now your Windows 11 partition.
14. Do step 7.
15. You can now see the Choose the operating system screen, choose Windows 11.
16. Do Step 8.
17. Restart your system, and check if your 10 and 11 is detected by Windows Boot Manager (or GRUB, or others)

Now it is OK.

Talk about sledgehammers to crack a nut.

Here is my method to create a bootable external usb hard drive.

1) get iso

2) use rufus to create a windows to go drive.

3) set pc bios to boot from usb drive.

Hi there
The problem with that method is that it doesn't "Clone" your current system -- it boots OK but then it's basically a blank -- i.e clean Windows system.

Yes it's a simple a, quick and easy method if you want to create a new Windows system from scratch - I agree but sometimes one doesn't want to go through the whole exercise of re-installing everything over and over again together with various updates (not only of Windows but also applications) etc etc !!!!!!

Cheers

then

1) image backup C drive

2) get iso

3) use rufus to create wtg drive

4) restore c drive image backup over clean c drive.

Geez like he said 'Talk about using a sledge hammer to open a peanut
I guess you guys don't like "Easy BCD"
So simple, Create the ISO on MS media creation tool, Boot to USB drive and install on an empty partition.

Why even use the third party program EasyBCD when all you need is the bcdboot command built into Windows 10 and 11?

My older computer is a Dell Inspiron 530a (from 2009). The primary (internal) hard disk drive (HDD) (Seagate 1TB) has two boot partitions. Windows Vista (Dell OEM) is on one and Windows 7, which is what I use, is on the other. The second internal HDD (Western Digital 500GB) has the 'free' copy of Windows 10. To get to Windows 10 (almost never), I change the boot drive in BIOS. When not in Windows 10, I use part of that drive for storage.

My newer computer is a Dell XPS 8920 (July 2017). The primary boot drive (internal, Dell OEM Seagate 1TB HDD) has Dell OEM Windows 10, but I upgraded that drive to a 'new' ("Recertified Product" - thanks Amazon!) Seagate 2TB HDD (in the system now). When I attempted to clone the OEM drive to the 'new' 2TB drive, the clone failed miserably. (See Windows 10 Forums and Intel Community Forum.) The 2TB drive has a "Reset" copy of Windows 10, and yes, it took days to bring that drive up to speed with what I had before. In the process, I discovered that the Dell OEM drive may be failing, so the 'new' 2TB drive may have saved my bacon.

Short story long, I intend to clone the 2TB drive to another drive (most likely another 2TB, but maybe a SSD SATA), and put Windows 11 on that. I can do the BIOS trick to switch boot drives. The only fly in the ointment is that my system has Intel Optane Memory to accelerate the boot drive. I will have to Disable that before I switch from Windows 10 to Windows 11.

Microsoft claims that you can 'evaluate' Windows 11 for "ten days" before you have to make a permanent decision (Windows 10 or 11). I got dragged into Windows 10 kicking and screaming, because Dell did not have a Windows 7 option when I bought the XPS 8920. It may take me weeks, if not longer to see if I even want Windows 11.
