Win10+ Setup Disk (Works with UEFI Secure Boot / BIOS / Install.wim over 4 GB)

Win10+ Setup Disk 2.8

Spoiler

About
This fully automated script creates a customized Windows 10 or 11 Setup disk.

• For both UEFI/GPT and BIOS/MBR boot process.
  
• For systems that use UEFI with Secure Boot
  
• For Windows ISOs that have an install.wim over 4GB -- due to the 4GB limitation of FAT32.
• Works on a USB thumb drive or external hard drive
• Tested on Windows 10 & 11 64 bit

What the script does

• Mounts your source Windows ISO.
  
• Converts your target USB disk to MBR partition scheme.
  
• Creates a FAT32partition. Copies all the necessary boot files/folders (“boot” folder, “efi” folder, “bootmgr”, “bootmgr.efi” and “boot.wim”) from the Windows ISO to the FAT32 partition then hides the partition.
  
• Creates an NTFS partition. Copies the entire contents of the Windows ISO to the NTFS partition.
  
• Adds Legacy BootMenuPolicy to the BCD store to show a progress bar while booting on Legacy BIOS systems.

Advantages

• No need to split or convert a Windows 10 or 11 Install.wim that is over 4GB
• No need to disable Secure Boot

Limitations
You cannot create a Win10+ Setup Disk on Windows 10 versions 1507, 1511 or 1607 Host OS. These older versions of Windows 10 do not support reading and creating multiple partitions on removable storage devices.



Note for Windows 11
Win10+ Setup Disk just creates the setup disk for installing Windows. In case your computer doesn't meet the minimum system requirements you will have to figure out bypassing it on your own



Thanks to
@BAU, @abbodi1406 et al. for their collaboration



Changelog

Spoiler

2.8 (Jan. 26, 2023)
Removed the read-only attributes when executing "bcdedit" which was causing difficulties
To initialize the USB disk, the first action is to invoke the disk management cmdlets, if it fails, diskpart is executed

2.7 (Apr. 6, 2022)
Some improvements to the UI

2.6 (Nov. 28, 2021)
Made improvements to the script and the UI

2.5 (Nov 23, 2021)
Changed the name of the script
Cleaned up the script
Made some UI changes

2.4 (Jul 21, 2021)
Can now create a Setup disk using a usb thumb drive or external hard drive

2.3 (Oct 18, 2020)
Some improvement to how the script is executed

2.2 (Oct 17, 2020)
Some cleaning and cosmetic changes

2.1 (Oct 11, 2020)
Boot (Fat32) partition is now hidden so the Win10 Setup Disk only displays one drive letter
Few modifications on how the script is executed

2.0 (Oct 3, 2020)
Renamed the script to Win10 Setup Disk
Few cosmetic changes

1.9.2 (Sep 12, 2019)
Made some minor modifications to the UI.
Also some changes to the script on how the ISO is selected.
The consoles text and background colors are now consistent with one another.

1.9.1 (Sep 10, 2019)
Separated the "Select ISO" and "Create Disk" buttons so you still have opportunity to change your choice of ISO before creating the installation disk.

1.9 (Sep 10, 2019)
Changed the name of script to "Win10 Installation Disk"
Made corrections and modifications to the script.

1.8.2 (Sep 9, 2019)
Enabled Visual Styles

1.8.1 (Sep 8, 2019)
Cleaned up the script and made some minor changes to the script and UI.

1.8 (Sep 6, 2019)
Reverted to the original design and improved the UI to be more user-friendly.

1.7 (Aug 30, 2019)
More fixes in the elevation of the script.
More changes to the UI. Updated to a flat design.

1.6 (Aug 29, 2019)
Corrected the script where it aborts when not run as Administrator.
More changes to the UI.

1.5 (Aug 26, 2019)
New user-friendly GUI.
Shows a progress bar while booting on Legacy BIOS systems. (Added Legacy BootMenuPolicy to the BCD store.)

1.4 (Aug 15, 2019)
Converts the USB disk to MBR scheme. (In case your USB disk was converted to GPT scheme. Otherwise the script will fail in creating the installation disk.)
Sets the NTFS partition as Active for Legacy BIOS systems.
Modified the USB drop down list to show the disk/s and its partitions.

1.3 (Aug 7, 2019)
Did some "housekeeping" to clean the script.
Modified the script to remove "cosmetics".

1.2 (Aug 5, 2019)
Uses a GUI for creating the Windows installation disk.
Uses a hybrid batch-powershell format to elevate and run the script

1.1 (Aug 2, 2019)
Modified the script so it runs without echoing to a .ps1 file.
Uses reg_takeownership to elevate script.

1.0 (Mar 13, 2019)
First automated script.

OK updated the OP script and download link

 

Would be nice if this was a GUI

 

I just help make it available here

 

Will the file browser dialog work with selecting the usb stick?

 

too bad

 

OK modified it a little bit and updated the OP. Thanks again rpo

 

Nice What do you think of this? No more "Mount the USB stick and click "OK" when ready."
Also what do you think about the "$USBDiskForm" the size of the Windows "Run" window?

No I just took out these lines.

Code:

echo $wshell=New-Object -ComObject Wscript.Shell
echo $wshell.Popup^("Mount the USB stick`r`nand click ""OK"" when ready.",0,"USB stick"^) ^| Out-Null

So it skips the "Mount the USB stick and click "OK" when ready." pop up window and goes straight to the "$USBDiskForm"

When you click "Run" in the Start menu... the little run window

 

What do you think about something like this?
