Good day,

can anyone help me please. I have changed the boot order to USB, I have disabled secure boot and even disabled the USB3.0 controller on the laptop and it refuses to boot from the flash drive (The flash drive boots fine on my desktop pc). I used DiskPart to completely remove all traces of windows 8.1 (after making back ups of course).

Any advice would be greatly appreciated

Did you make a boot drive of win7 or just paste an .iso on it ?

it's bootable. Used Rufus even tried winsetup from USB. Like I said, when I plug it into my desktop and reboot it boots up with the flash drive like its supposed to. I read that one needs to change UEFI Boot to CSM boot, nut just as luck will have it this particular laptop's BIOS does not give me that option

Make sure you select the usb flash drive !! andbackup your data
Then download Windows 7 USB Download Tool and select your usb drive , click next and select your iso , then let it do it's stuff and boot from it again
I always did this and it worked

Here is what you need to do: (POINT 3)

1) Boot unit and press F2 to get into BIOS
2) Go to "Security" tab and disable "Safe Boot"
3) Go to "Advanced" tab, select "System Configuration" then change boot mode from "UEFI" to "CSM"
4) Press F10 to save changes and exit.

Now you can load win7 setup and use all advanced drive-options ;) 

Good luck,
Inge

Same problem here with a Satellite L50-B, I´ve tryed all the above. Tell if it worked for you... If it does the only thing that could be wrong is my ISO to USB (but used it already with sucess in other laptop/desktop).
Just a diference: my laptop never did boot from USB. Tryed F12 boot menu and boot order in BIOS. In UEFI always goes to instaled windows and in CMS it says the disk as no system (or bootable system).
I use Windows 7 USB Download Tool and a ISO that always worked out fine, only difference is the laptop. The other one was a L500 with 8.1 pro 64bits and this is a L50-B with Toshiba OEM 8.1 (full of "garbage")
