Shawn if I am using option one do I have to format the USB stick before I make the installation drive?

Thanks for the clear description of the steps to do this. I've just tried this for the 20H2 ISO.
Were you aware that if you repeat the dism /ExportImage with a different index, but the same output file you can add a second edition?
Here's a slimmed down 20H2 install.esd I've just made, just containing Home and Pro.

NTLite will also do the heavy lifting for you.
1. Download -
Download – NTLite
2. Run NTLite and click on the Add icon.
3. Select Image file.
4. Navigate to the location and select the file (install.esd or install.wim).
NTLite will display the list of Windows versions contained in the file.
5. Right-click on the appropriate version, and select Export. You have the option of .ESD (compressed) or .WIM format.
6. Select the location to save the new exported image file.
Bree,
Thanks. I've added that to my post.
- In the only example I have worked through, a x64 multi-Edition 4.29GB install.wim reduced to a x64 Home-Only 3.73GB file.
- So there certainly seems to be enough room for, say, a x64 Home & Pro install.wim or possibly a x64 & x86 Home install.wim
- I was going to try it out for a 20H2 ISO but my first download attempt resulted in an invalid file because of an interruption and I have not tried again because I then saw the discussion about the changed behaviour of Repair installs within 20H2 [inability to preserve programs & data]. I'll keep my fingers crossed that this issue is resolved by 11th May 2021 [Ver 1909 end of support].
Happy Agincourt Day,
Denis
Create_a_bootable_Windows_USB_device.bat
@Brink, I have put option 4 into the above batch script. Users only have to take two steps: (1) select an ISO file and (2) select a USB device as shown below. Would you consider adding it into this tutorial?
Step 1: select an ISO file in the dialog box.
Step 2: key in only the Disk number of the USB device, for example3
The script will automatically choose betweenFS=FAT32
andFS=exFAT
as per the size of "install.wim" or "install.esd".
The copying will start as soon as DiskPart has completed the operations.
When the copying has finished, it will display the following:
![]()
That script needs to start with a warning that, if the install.wim exceeds 4GB, it should only be used for those computers that have been demonstrated to be capable of being booted by an exFAT/NTFS disk.
