You could, however, reinstall 10 on the laptop because that key is stored on the PC in various places. Anyways to solve your problem, the Toshibas boot menu key should be F12. Repeatedly press that key on the start up of your PC. Select USB if your bootable windows are on that and if that doesn't boot, you goofed up somewhere with making it (or you have a corrupt version of 7). Personally, I would go back to windows 10 and you can get a clean ISO from the media creation tool.
Also, what are you using to make the bootable USB? You're not just throwing the ISO over on the USB, are you?
It is a genuine version of windows 7 I'm trying to install. I have got a product key alsom
I've tried previously a few times to create the bootable usb with windows 7, each time it is never recognised.
How can I go back to windows 10 now that my system has no OS? By that I mean, I have a bootable usb with windows 7, and I havent got a second computer to try put windows 10 on again.
I have used both rufus and unetbooten to create the bootable drive, each time following the same advice on multiple tutorials
Thanks for the advice also
