This looks more like the known inability of SYSLINUX EFI code to handle
optical media. Nearly all other bootable GNU/Linux ISOs use GRUB for EFI.

If your machine's firmware offers legacy BIOS mode (aka CSM) then you
could try whether the DVD boots successfuly in this mode. If it succeeds,
then you know that SYSLINUX EFI code is the cause of the failure.


BTW: Did you find out why you got the GRUB prompt back in juli ?
