Installing Windows 7 alongside Windows 8.1 - mrnapolean1 - Jan 24, 2015
I have a Toshiba Satelite L50-B Laptop that shipped with Windows 8.1.
I would like to dualboot Windows 7 Ultimate with this. I have already disabled Secureboot (within the UEFI BIOS) and it will read my Windows 7 Ultimate x64 DVD until the Starting Windows animation.
It will freeze while trying to play the animation.
My Windows 7 x64 Flash drive will not load at all unless I switch the Mode in UEFI BIOS from UEFI to CSM.
Then it will work till I get to the Hard drive part. It says this: "Windows cannot be installed on this disk. The selected disk is of the GPT style."
Windows 8.1 will not load in CSM Mode.I have to change it back to UEFI Mode.
Now I get options from within Windows 8.1 to boot to the following:
EFI Network
EFI USB Device
EFI DVD/CD ROM
Doing the EFI USB Device option will not boot my Flash drive.
Any suggestions to get Windows 7 Ultimate x64 without wiping and losing Windows 8.1?

Are you sure the Windows OS ISO you downloaded is not damage because it could be corrupted which will cause installation problem. Use Rufus program to create UEFI USB installation media from Windows 7 ISO fie. Download Windows 7 ISO from below website.

The ISO File was created from an Official Holographic Windows 7 Ultimate x64 Installation Disc using a program called IMG Burn.
I have done many installs with this ISO So I am pretty sure its not corrupt.
For my flash drive, I used the Windows 7 DVD to USB Tool from Microsoft.

Have you not even going to try my advice to you about creating a UEFI USB installation media with Rufus program.
