Description of problem:

I just tried to boot Mageia-5-beta3-Live4-x86_64-DVD.iso in qemu in EFI-mode, and there are two Problems i think:

The cmdline from grub menu is 

BOOT_IMAGE=/boot/vmlinuz root=mgalive:LABEL=MGALIVE UEFI quiet rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0

but the filesystem's label is (from blkid)

/dev/sr0: UUID="2015-02-11-21-53-27-00" LABEL="Mageia-5-KDE4-LiveDVD" TYPE="iso9660" PTUUID="119a5c31" PTTYPE="dos"

Correcting the label in grub to Mageia-5-KDE4-LiveDVD leads to (from rdsosreport)

[    1.488665] cdrom: Uniform CD-ROM driver Revision: 3.20
[    1.489359] sr 1:0:0:0: Attached scsi CD-ROM sr0
[    1.577958] FAT-fs (sr0): invalid media value (0x90)
[    1.579164] FAT-fs (sr0): Can't find a valid FAT filesystem

The rdsosreport from that boot is attached. I was able to boot with the corrected label and removing UEFI from cmdline, so it now reads:

BOOT_IMAGE=/boot/vmlinuz root=mgalive:LABEL=Mageia-5-KDE4-LiveDVD rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0



Reproducible:

Crap, so it boots according to the grub.cfg meant for USB installs, instead of reading the correct uefi boot info from efiboot.img that is tagged as efi boot data on the iso :/


I guess I need to re-add the separate "from USB" enties to work around this.
