How to reduce the installation image to burn in a 4.38 GB DVD

If you don't want to compress it to ESD, just burn it with PowerISO at low speed (used it many times to burn 4.37 GB files on a DVD-5 without issues)

 

Hi,
I faced the same problem with the fat32 multiboot Pendrive while making a bootable drive for windows 10. Because of the size of install.wim containing multiple versions of Windows 10 was greater than 4 Gb. So I decided to extract the only version I needed from install.wim and then use the iso.
There is software available in windows 10 with CMD called DISM one can find details on Microsoft's website it can be used to extract the single version from install.wim.
For that, you should extract the install.wim from iso file from folder ISO:\sources using Power iso software then put install.wim in c:/ windows /system32 folder.
Run 1st command to get versions and their index in install.wim
Dism /Get-WIMinfo /wimfile:install.wim
Then extract the version to new install.wim

Dism /Export-Image /SourceImageFile:install.wim /SourceIndex:<index number you require> /DestinationImageFile:install2.wim

Now you have install2.wim get it and rename it to install.wim. Open power iso delete original install.wim from iso, put the new one in iso file at ISO:\sources using power iso software and done.
And don't forget to remove the original extracted file to remove from c:/ windows /system32 folder it will just take your space.

 

The install.wim is not located in that folder, it's in "ISO:\Sources".... and when you replace install2.wim with install.esd and set compression to recovery, you will end up with an install.esd which is 30-33% smaller then the install.wim.

 

U can burn to a dual layer dvd but their not cheap.

 

Off topic

I apologies for posting an off topic query but I wanted to know, can't we use the NTFS formatted USB's to install Windows 10 ?

 

Yes, it will only install when legacy bios is set, no uefi installs.

 

Thank you for the answer. Which brings me to another question, can we have a MBR table with UEFI boot and GPT with legacy BIOS, or is this association is strictly associated ?

 

FAT32 formatted USB will be able to boot both, Legacy BIOS/MBR & UEFI/GPT, if that is what you meant.

 

yes you can. I do it all the time.
rufus and other tools can create an USB drive, formatted with NTFS, which can boot from UEFI.
the tools inject a NTFS driver onto the USB drive, which gets loaded when you boot from it.
but I think this only works with secure boot disabled (not sure about this).
