Toshiba Satellite c50 a 16c - cannot get it to boot from any known good DVDs or ext usb cd roms.

PSCG6E 06D001EN

I want to test the memory.  But I cannot boot from any of my boot cds inc
Memtest
Windows xp
UBCD
Knoppix
etc etc ...

Error .... Checking media ...
Media fail ...
No bootable device - Please restart system ...

Note ... Ive added a blank hdd as Im testing the hdd in another computer for faults.
Dont get distracted by the above statement.

I gone into BIOS and changed boot order
USB
CD
Hard drive

Attached 2 different ext USB cd roms - same problem ....

Laptop is one week old.  Possible Lemmon.

Mistified.

Please note it goes into Win 8 BUT the end user reports that it gives errors and I want to test the memory.

Im then going to nuke it as the user says no data on board.

BUT .... why cant I get it to boot? Some other problem under the hood there me thinks.

You will probably have to disable Secureboot and possibly also change to the old BIOS mode.

You are indeed correct.

Ive never seen the like before.

Ive changed it to "CSM Boot" and it worked.

Do I have to change it back for Win 8 to work?

Windows 8 doesn't need secureboot to be on to work, but it is supposed to protect against malware that can be caught from unauthorized boot media.

I don't know. This is a "feature" m$ has made the hardware manufacturers adopt for any PC that is delivered with Windows 8 pre-installed. In my point of view the real reason for this is that it is harder to install a non m$ OS to such a PC. Although on those that come with normal Windows 8 (not RT) it has to be possible to turn off, on ARM based devices that come with Windows RT you can't turn it off, and so on that hardware you are stuck with Windows RT.

Last question ... What are ARM devices ?

rindiCommented:
ARM are simple, cheap CPU's which use a different codeset than the intel/amd x86/x64 CPU's use. They also normally don't require as much power and don't heat up as much, and so they are usually built into mobile devices like phones, tablets etc. But they are also being targeted for servers now which would then reduce the cost for the hardware and infrastructure.
