Red Hat Bugzilla – Bug 1282599
Triple-O ISO installer does not support UEFI
Last modified: 2016-10-03 15:03:11 EDT
Description of problem:
Installing Triple-O ISO install fails when booted using UEFI.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot Triple-O ISO from UEFI
Failed to write bootloader configuration
Working Triple-O environment
Same system works fine with same ISO and legacy (CSM) BIOS.
os-prober shows: /dev/sda4:Red Hat Enterprise Linux Server release 7.1 (Maipo):RedHat:linux
Problem occurs in post-installation steps (os-prober/grub2-mkconfig).
RHCS-I (Sat 6) ISO appears to install OK, testing launch-fusor-installer now
https://bugzilla.redhat.com/show_bug.cgi?id=1282599 complicates testing Sat6 ISO.
If it's happening in post installation we might just be missing a package or packages. I'll take a look and see if I can sort it out.
I don't know why yet, but it's trying to write grub.cfg in /boot/efi/EFI/fedora instead of redhat. Still investigating.
The product title needs to start with Red Hat, otherwise anaconda guesses it is Fedora. As we have it set to RHEL OSP Undercloud that's why it's breaking. I am spinning a new ISO with it changed to Red Hat OSP Undercloud until they decide what they want it to be that will also satisfy anaconda.
Verified in 20151118.t.3.
Please note that the system I tested on was a Dell. The reboot said "No boot device available" when boot mode was set to BIOS.
It worked fine when boot mode was set to UEFI. May be worth doc text.
