Windows – Create UEFI-bootable DVD with Windows 8.1 iso

bootinstallationuefiwindows 8.1

I'm trying to set up a UEFI-boot of Windows 8.1. However, I seem to be unable to install it with a USB drive (previous question), and when I try to install with a DVD (the same iso), I don't get the UEFI boot option on startup, contrary to what happens when I use a DVD burned with e.g. an Arch Linux live install.

How exactly could I be able to boot with UEFI my Windows 8.1 iso from a DVD?

You need to setup boot-loader inside your bios settings.

If your computer has enabled Legacy Support, disable it if you want to have UEFI support.

You would need to setup UEFI boot order and setup the DVD as the main source in some cases.

Also try to disable Secure Boot in your bios settings to successfully install the system in UEFI boot mode.

We need more info about your motherboard or a laptop if you want us to help you with more details.

Please clarify: can you boot that CD in both BIOS and UEFI modes? E.g. does it have two boot records in boot menu or a mode switch knob?

Preparing a UEFI-bootable USB flash drive is actually way simpler compared to an ISO, at least has been so in my experiments: a FAT partition with EFI/BOOT/BOOTX64.EFI which knows what to do next compared to specially crafted El Torito boot floppy image with the same crap.

Maybe you'll need to extract that efiboot image, mount -o loop it and extract the contents into EFI/BOOT directory.

Open an admin command prompt, and enter the following:

diskpart
list disk
select disk x (where x is the number of the USB drive from "list disks")
clean
create partition primary
format fs=fat32 quick
active
assign
exit

Mount the ISO image (in running Windows 8, just double click in Windows Explorer).
Copy all files and folders from the mounted ISO drive to the USB drive. You can use Windows Explorer, or xcopy x:\* y:\ /s /e, replacing x: with the ISO drive and y: with the USB drive.
