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

I don't understand why any of this is necessary. So the install.wim is bigger than 4gb...split it to 4gb or less .swm files. Put the whole thing on the fat32 and you can boot legacy or uefi from fat32. One partition, no sweat. I must be missing something...what?

 

indeed, you are missing something, read about this in the previous posts, why this is necessary
Answer is in the BIOS, as a tip

 

It must be something to do with 20H1. I've just upgraded my ADK to this build & have noticed my WinPE no longer shows the UEFI logo but the Windows logo & my WinPE is at a lower resolution.
Copying back the 19H1 WinPE wim's & all is back to normal...

 

I use a 128GB USB3 key for all my installations. All the Windows and Server Editions I need are included. ESD is much easier to maintain & install from...

 

i don't know what was wrong with my USB or the script.
I'm getting this error all the time

 

got the error,
the device manager wasn't recognising my USB drive, so I went to properties and made driver update, thereafter all went fine as it should be.
Thank so for the response

 

Some people get worried because the file explorer shows the two partitions on the usb disk : just remove the driver letter from the fat32 partition by additing the following statement after line 177 (remove-item ($env:temp + "\bcd.*") -force) :

Code:

Get-Volume -DriveLetter $usbfat32.substring(0,$usbfat32.Length-1) | Get-Partition | Remove-PartitionAccessPath -accesspath $usbfat32

 

No, it will not work because you can't hide tha fat32 partition as you have robocopy and copy-item statements. Hiding the partition removes the drive letter.

 

Yes, this will work. I will adapt the script and i found the correction for the detail you observed.
