From 0f4cc4b5a7f780111c3ef2e1d4bba175896f8537 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 23 Nov 2021 15:20:09 +0000 Subject: [PATCH] [build] Include EFI system partition table entry in isohybrid images Add the "--uefi" option when invoking isohybrid on an EFI-bootable image, to create a partition mapping to the EFI system partition embedded within the ISO image. This allows the resulting isohybrid image to be booted on UEFI systems that will not recognise an El Torito boot catalog on a non-CDROM device.
