[Solved] Toshiba Satellite C50-A Windows 7 Installation Problem

Today it was hectic day for me, spent hours to find the solution for above mentioned problem and finally found the solution, i am going to share with you. problem is one of our client who bought Toshiba Satellite C50-A from us few days back, came back and told us , he couldn’t install windows 7 on this laptop, only windows 8 can be installed on this laptop. if you are facing same problem here is the solution.

1. Cause of this problem ” this laptop is designed to work with GPT based OS. it wont let you install MBR based OS”
2. in some cases the only thing that could work is go to bios by hitting F2 and then go to security menu and turn off the secure boot option, as shown in the image below

3. if you are lucky the laptop should boot up with windows7 DVD, and if still it doesn’t boot , again go to bios, and go to advanced menu and see if you find boot mode option there, if it is available then you have to chose CMS boot instead of UEFI boot , save settings and restart.
if the above solution doesn’t work, go to step 4
4. as you can see in the image below , there is no option available to chose the boot mode, this laptop was locked to UEFI boot mode by company, we have to unlock this menu,

5. to unlock the menu we have to flash the bios with the version that have “boot mode” option, no need worry, i have created an ISO image for this bios update that you can download from this link
Note: Please Only Use Firefox to Download Bios Files
Warning: “if you don’t know how to flash bios, you may corrupt the bios and then have to change Motherboard”


6. Once you downloaded the Bios ISO image, create bootable CD using this ISO, you can burn iso file with power iso available for free.

7. You must Plug in the AC charger before you start to flash Bios,  Once you boot up with this CD, you will see the following screen, you have to type “flash” and hit enter, as you can see it in the image below.

8. Bios flashing should start, wait for 5-10 minutes until it completes. you will see progress bar, once its finished the laptop should restart, if it doesn’t restart for long time, press the power button by yourself and turn it on.

9. Once the bios installation complete you will see the boot method option in your bios,
now disable secure boot option and chose CMS boot method and insert windows 7 DVD  into the DVD ROM, and start the installation.

    you must burn cd & then use internal cd driver only

  238. Jeff Watson says:

    I'm afraid I have ruined my laptop I just purchased from a pawn shop by messing around trying to figure out how to install Win7. Somehow I guess I entered a bios password but I don't remember doing so. It wants the password when I boot and will go no further. It will not boot from a DVD or USB device for me to flash the bios. Is there any hope? Maybe motherboard jump points? Thanks for any help.

  239. Jeff Watson says:

    It is a Satellite C55-A5105..I guess that is probably important. 🙂

    thanks for the guide mate! Been a big help, wanted to change the OS "Operating System" and was wondering why my install disk was not working, and found out it was in UEFI mode instead of legacy/CSM which is needed to install Windows 7 . Location to change boot option Adavnced>System Configuration>Boot Mode>CSM Boot.

    If you don't have that option then you need to update your BIOS "Basic Input Output System" and follow this guide as it is spot on! I didn't not personal download your ISO. I went onto The offical toshiba website and entered in the details of my laptop, and got the specific version for my laptop you will need to get version 1.30 or higher to add the option boot mode to the BIOS if you don't have it.

    Thanks for you guide it's been a big help
