Hi,

My laptop has Secure boot enabled and Legacy support disabled.

I want to create bootable USB using win 10 .iso image that should be detected on this secure boot enabled laptop.

Using rufus, when i select the iso file and MBR partitioning scheme for UEFI /CSM, it goes back to NTFS formatting.

If i use FAT32 or Large FAT32, it says iso file not compatible with FAT32, use another file system.

If i use NTFS and create bootable USB for my personal secure boot enabled laptop, the USB shows up in the boot menu at startup, but it is not able to install windows.

If i disable secure boot and enable Legacy support along with UEFI also present on my personal machine, the windows starts to install.


OTHER THAN THIS, IN MY ORGANIZATION, SECURE BOOT IS ENABLED ON LAPTOPS AND WE USE 64GB USB and format it using LARGE FAT32 using rufus, and then copy our windows image from network using some internal software.

That USB created in our organization boots up with secure boot enabled machines coz they are FAT32 partitioned USB drives.


Is there any solution to create bootable stick win10 which can be detected on secure boot enabled machines?

Mainly the point is I want to create bootable USB stick which can be detected by secure boot enabled machines, and what i have known is that secure boot supports fat32 formatted bootable USB drives.


However what i tried is that, on my personal laptop, I enabled secure boot and first installed organization Enterprise windows.

After that, i inserted my USB and browsed it from This PC and run the setup.exe file manually.

It worked, but my issue still is : I want to create bootable USB stick which can be detected by secure boot enabled machines, and what i have known is that secure boot supports fat32 formatted bootable USB drives.


Anyone with a positive and working solution who has understood my question perfectly, please reply.
