freddie-o, some clarifications needed from you on the above. Does it mean that in order to create the said UEFI bootable USB, the windows I am using to create it must be of Windows 10 v1703" (Build 15063) and later versions? Thanks for sharing of the tool and I intend to use it once you cleared my doubt.
Yes, earlier versions of Windows do not support reading and creating multiple partitions on removable storage devices. MS only started support for multiple partitions on removable media on Windows 10 Version 1703.
I love this script that addresses your problem. It creates a fat32 and a ntfs partition to your USB drive. This will allow a legacy install or an UEFI GPT install. https://forums.mydigitallife.net/th...-with-secure-boot-install-wim-over-4gb.79268/ Also see these 6 options to get around the 4GB size limit of fat32 https://forums.mydigitallife.net/th...tems-with-install-wims-larger-than-4gb.79199/
I agree, these two threads really very informative and summarize everything about UEFI bootable USB. Freddie-o, good job & thanks for sharing.
The statement on its own is misleading (and some people will read just that bit), you do need to emphasize that using the script will actually do it!
In case of Legacy BIOS boot, you should ensure that the USB disk partition is active : Code: $usbfat32=(New-Partition -DiskNumber $usb -UseMaximumSize -AssignDriveLetter -IsActive | Format-Volume -FileSystem FAT32 -NewFileSystemLabel "Windows Installation Disk").DriveLetter + ":"
Mount your Windows ISO. Navigate to "sources" folder. Locate "install.wim". Right click "Properties". Usually this is the error you get when the install.wim is beyond the 4GB limit. Win10 Installation Disk 1.9.2 is for install.wims over 4GB
To avoid confusion... Win10 Setup Disk 1.9.2 [For UEFI or BIOS / UEFI with Secure Boot / Install.wim over 4 GB] Setup disk [For UEFI or BIOS / UEFI with Secure Boot / Install.wim under 4 GB]
@rpo I don't know why I only noticed this now when booting into uefi the windows cover the entire screen
