Hello,

Is there any way to prevent Rufus making two different partitions like this

That is the GPT System Drive scheme.

Take a GPT HDD/SDD an Plug in as secondary or USB drive and you will see 2 or 3 (auto mode) partitions.

This is due to the install.wim image exceeding the 4GB file size limit of fat32. The only way to prevent it making an NTFS partition which isn't compatible with secure boot is to compress the install.wim to an install.esd.

Hey Kasual & raidensnake

So, basically, there is no way to have a single partition while making a bootable PD in GPT-UEFI via rufus? Right?

Is there any alternate software like rufus that does the job i.e. making GPT-UEFU based bootable PD with a single partition?

& yes, my NTL-ISO size is currently around 5.14 GB so for that neither I can go with FAT32 partition schematic, nor I can choose the MBR method in Rufus as shown in SS below

As my HDD & SSD, both are formatted in GPT so if I do so, i.e. made the PD bootable at MBR-UEFI-CMS (LEGACY) mode, then the Windows won't install in those partition with re-formatting them again in MBR & I really don't wanna do that.

I just explained how to resolve that. You need export your install.wim to an install.esd file. Where you have the iso listed in NTlite you need to right click on where it says install.wim, select convert and select ESD (high compression, read only) and make sure replace source image is ticked. That will compress the image to below the 4GB limit. Then you need to rebuild your iso by right clicking your installation image folder and selecting create iso. Once your iso is rebuilt with the esd file rufus will then be able to put the entire installation onto a single GPT partition.
