Hi.
The installation DVD (SL-64-x86_64-2013-03-18-Install-DVD) has "/EFI/BOOT"
directory, but it's missing the important ".efi" file.
Thus, the DVD isn't recognized by UEFI firmware as EFI capable booting
media, and it can be booted only using "legacy" (BIOS) booting.
That's making further problems, because according to
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ch-Boot-x86.html:
"
Therefore, the installed system must boot using the same firmware that was
used during installation. You cannot install the operating system on a
system that uses BIOS and then boot this installation on a system that uses
UEFI.
"
Therefore, Anaconda assumes that the system isn't UEFI, and makes wrong
decisions, which cause SL to not boot, until manually hacked.
Researching .
