SATELLITE PRO L850-1KM

I have a SATELLITE PRO L850-1KM and have a problem booting up from CD/USB. I've burnt a fresh Windows 7 cd as I didn't want the preinstalled Windows 8 crap but when I hold F12 and go to the boot options it says 'Media Check: [Fail]'. I can hear the CD spinning up but it doesn't work. I've also tried a bootable USB stick! It's asif Toshiba don't want you to install your own OS. :/

This is a brand new laptop btw.

  1. Same Problem here. Took the 640gig HDD out, installed a 500gig HDD and the system will not recognize any of my USB drives or DVD/CD. Tried Ubuntu Images and Win7 Images
  2. Bought it from Best Buy for $399...............BIOS Sucks, lol
  3. Fixed it!


    I just bought this Laptop tonight and I got it figured out. I did this per my unit Satellite Pro L850. If you have a better work around let me know.

    To Install a different OS in Windows 8 models Satellite / Satellite Pro L850 Series Laptops:

    (1) Shut down the system while pressing the SHIFT key to completely power off.

    (2) Power on and press F2 while the TOSHIBA logo is displayed to enter the BIOS Setup Menu.

    (3) Go to the Security tab and set the "Secure Boot" setting to "Disabled".

    (4) Go to the Advanced tab, enter "System Configuration"and set the Boot Mode to "CSM Boot."

    (5) Press F10 to save and exit.

    (6) Boot from the DVD/CD-ROM/USB By Pressing the F12 Key (I tap it)

    (7) BOOM! Your Done!
    Tested The following Operating Systems VIA USB
