Toshiba Satellite C55-A5105 Removing Windows 8.1 Installing Windows 7
Yeah, yeah, I know, I know... We all got excited by getting this new laptop from Toshiba but... since there’s no much information on the web regarding this product and how to downgrade it to Windows 7 well… I decided to take the challenge, it took me awhile but...
Guess what!? !!!!...
I figured it out!!! I manage to install all the drivers including the Flash Cards Utility better known as Added Value Package.
Keep reading it gets better! ;P
Probably you hate Windows 8.1 as much as I do, so as soon as I got this laptop I spent many days looking into forums searching for solutions on the web in order to install Windows 7 on it (trying to make a dual-boot machine) but none of them seem to work there was always something missing or just not working properly. So that been said lets get rid of that shitty ass Windows 8.1 because there’s no way to install Windows 7 directly. So don’t waste your time by making a partition on the HDD it won’t work.
So here’s what we’re going to do, first! make a image from the actual Windows 8.1 or just make a driver backup using this tool (the important part are the drivers even though you can get them in the Toshiba site is better getting them this way, (more comfortable)
Once you install it (Driver Max), make a back up with it, the program is very straight forward so I don’t think anyone will have any problem with it.
Windows 8.1 driver backup:
Once you’ve done the driver backup put them in a USB flash just keep them safe!.
Make sure you install the latest BIOS V1.40 for your computer WHILE STILL HAVING THE WINDOWS 8.1 INSTALLED ON YOUR MACHINE because this update will allow you to change from UEFI to CS BOOT or better known as “Legacy” (so you can make the Windows 7 installation on your computer because the previous versions got no option to switch it to CS BOOT) otherwise you won’t be able to install Windows 7 because the UEFI is some kind of validation for Windows 8.1 so they basically want to force you to use Windows 8.1 only in this machine.
You can get the latest BIOS (V1.40) Update here:
THIS IS ONLY FOR WINDOWS 8.1 ONLY! SO WE NEED TO MAKE THE UPDATE ON THE BIOS FIRST OTHERWISE WE WON’T BE ABLE TO UPDATED IT THROUGH WINDOWS 7.
You can learn more about the UEFI here:
Here’s how to access the BIOS:
The thing is if you change the settings from the BIOS from EUFI to CS BOOT then it won’t let you access the Windows 8.1 when you restart your machine, so here’s the tricky part. You’ll need a Windows 7 copy after changing from UEFI to CS BOOT then you can begin your Windows 7 installation, yeah but don't get that excited is not that easy!!!! in order to install it you’ll need to delete the Windows 8.1 partitions completely from the HDD, use the Windows 7 tool to delete the partitions on the HDD then format it, once you do that is when you can start installing Windows 7 the right way.
Here's a video about how to make a clean installation (Windows 7):
After the deletion (recovery, System reserve, etc.) start the Windows 7 installation it will install normal, as always.
You may ask yourself why do I have to delete the whole thing? (Windows 8.1) well it has a security that makes a validation that is in fact a Windows 8.1 copy (that’s why the UEFI thing) it works directly so automatically will look for it so the Windows 8.1 can boot up.
Ok here’s the other tricky part! you’ll love this one!!! the thing about installing the Windows 7 is that it will recognize almost everything but you’ll need to get this driver for the USB 3.0 so this one is the key for the rest of the installation but!!! guess what!?!?!?!.
It won’t recognize any USB port, so you’ll need to burn it into a CD or a DVD (the 3.0 USB driver) because is the only thing that it will work on the computer is the DVD drive so, if you have another computer burn the driver into a CD or a DVD then install it on the laptop.
USB 3.0 driver here:
Once you’ve download the Windows 7 drivers just restore them by using Driver Max tool, go to “restore” and look up for the file (the backup file with the drivers) that’s it wait for the system to restore them and restart the system.
Here’s the link for the Windows 7 drivers:
After restoring these drivers you should have something like this (I only showed those that are commonly missing)
