invalid looks better status, as uefi status support can still evolve :)

The wrong tree, Thierry. This bug is precisely about EFI booting the Live *DVDs* as such (ISOs); *not* about booting from USB. Do ISO DVDs have labels?

The Wiki states:
"the x86_64 liveDVDs are capable of booting in UEFI mode directly if burned to CD or DVD"
This bug is that this does not work. Confirmed identically by another tester:
"for me the Mageia-5-beta3-KDE4-LiveDVD-x86_64 from DVD boots to UEFI option screen, then: 
 dracut warning - could not boot
 error opening usb "discripters" file
  dracut warning - could not boot
 :/dev/disk/by-label/mgalive does not exist
 :/live/union does not exist"

The latest M5B3 Live ISOs are the first ever of that genre to EFI boot directly from *DVD*; previously they were not recognised as bootable.

Comment 2: Please justify that.

Wiki » UEFI how-to now says:
"Mageia 5 instructions 
 In general 
Starting with Mageia 5 beta 3, UEFI integration is done and install should be somewhat straightforward
For classical and live EFI installs:
Boot from real DVD should work out of the box."

So this bug seems to be valid. And important to those affected.

Yeah, it seems there is a lot of borked uefi out there.

on a real iso it should first pick up the efiboot.img that is mapped as eltorito-alt-boot to know how to boot from the iso, but instead it seems to read the config added for usb installs :/

I will probably add back the separate "from USB" boot entries to work around this for next iso builds... unless the other changes I have in mind "to completely ignore USB label for live medias too" will work during my tests

Yes, I would not defend my EFI BIOS for a moment. It is an early one, Acer special Packard-Bell; and misbehaves in other ways. OTOH a heap of other distributions have installed OK, all from DVD, so it is worth cracking this.

I am encouraged by:

Keep up the good work, Thomas.

I suppose this report can be used for classical isos, too, or is that a different issue?

On discuss-pt-br someone with EFI hw reported he gets
"Please select the  disk containing copy of the Mageia distribution install source." when booting the traditional beta3 DVD from DVD.
Selecting "CDROM drive" (and maybe the x86_64 directory) makes install continue.

I haven't found time yet to test myself.

Yep, same problem. 

So it seems I will have to add separate "from USB" install optionss for both classical and live medias to ensure they are usable...

OK, thx Thomas, adjusting summary

(I know most around think "media" is singular, but it is already plural. It is one installation medium, two installation media, see
http://en.wiktionary.org/wiki/medium#Noun item 6)

Summary: M5B3 Live medias do not boot from DVD on EFI hardware. => M5B3 installation media do not boot from DVD on EFI hardware.

Hi,

I have the same problem and added a file under (similar) bug 15250 before I have seen this one. Sorry about that.

Thomas can you regenerate EFI stuff (tarball) so that we can test it and close,it if it's ok?

CC: (none) => ennael1

Efi tarball  updated and adapted for RC builds

[Currently many e-mails to me are vanishing, so I have not seen all comments here previously]

My recent testing experience with M5betaX *does* have the Classic DVD booting to menu then Install on EFI (as it always did for M4). Hence this bug was originally specifically for *Live* DVDs. I guess the title has been changed.

Comment 8
> Yep, same problem
Which puzzles me... Never mind, M5_RC will soon show.

With the test traditional 64bit iso that ennael pushed today, and when in the UEFI(BIOS) legacy boot was not allowed, but only UEFI boot was:

booting from DVD into stage2 worked fine (after choosing the first item in the bootloader menu)

booting from USB into stage2 worked just as fine (after choosing the third item in the bootloader menu)

The bootloader menu itself was not very clear, because for the third item, of the string "USB" only the first part of the "U" was visible, it looked like an "L".

For the last item, more of the string "USB" was visible, but still not all of it.

Ah, I need to adjust the menu space so all text fits...

So basically this issue is fix apart from the menu spacing issue mentioned in comment 14? Any progress on this side Thomas?

That should have been fixed in last round of RC isos

Thanks!

Marja, Lewis, can one of you confirm?

The x64 Classic and Live KDE DVDs have been booting successfully from DVD on EFI hardware for some time now. This can be closed, I think.

Great, closing then. Thanks!
