Excuse me for a stupid question, but is the BIOS of the laptop configured to boot from that drive?

Can you check if you don't have any bios update on your dell host ?
Can you please report if its efi based or not.

Thanks.

There is not much to configure in the BIOS about booting. Booting from the optical drive (DVD/CD drive) is "enabled" and I can change the boot priority order. The optical drive is the first device in the boot priority order. What else in the BIOS could be of importance?  

For testing purpose I changed the "SATA Operation" from AHCI to ATA. Now the Mageia5 DVD boots and the install menu appears. Next I can run "Memory test" without problems (OK). When I choose to run the "Hardware Detection Tool" the screens turns black, only showing a blinking cursor, the system freezes and a power off/on reboot is needed to continue. After a reboot I can continue to install Mageia on my hard drive, but installing the packages is much slower than usual.

But changing the SATA setting is not a permanent solution. I suppose that it affects all other OS on this laptop (multiboot with Windows7 and Mageia3).

The BIOS (Dell/Phoenix SecureCore Tiano Setup) is not efi based.

This week I will check if there are updates available.

I'm very surprised that switching to AHCI solves the syslinux issue as it have very few in common.

Can you confirm switching AHCI back (which should be prefered for performance issues) trigger the same "cannot load ldlinux" error ?

I updated the BIOS to the latest version. That fixed the boot problem. I can boot from this DVD now.

But the problem with the Hardware Detection Tool remains (bug 13829).
