Hi guys!
I'm not exactly a tech person, so bear with me as I try to explain this.

I am using a toshiba satellite c55 a 163 (it's about 4 years old). I've had windows 7, 8 and 10. I installed 8 and 10 myself with no problems. I had burned the iso file on a flash drive and all I had to do was change the boot order in BIOS.

It's been 2 years since I last did that, and my laptop is running very slow. I got a free Win 10 Education from my university and I've been trying to install it, but something's wrong. I've changed the BIOS settings to boot from USB, but for some reason Windows just starts normally. I googled it and most threads say I should change to CSM option (whatever this means) and disable Security Mode. In the default settings, it was already set to CSM, so I didn't have to change that. However, I simply cannot find the Security Mode option. I've looked through all the tabs, and it's just not there.

Does anyone know how to make it boot from my USB? I can supply pictures of my BIOS screen if it will be of any help. Thank you in advance!!!

It sounds like the USB doesn;t contain a bootable system. Did you use Rufus to make the ISO bootable?

Try mashing the Function 12 key as soon as you power up to make certain it's actuially looks for the USB device. If it does and finds nothing, you need to make a new ISO.

Yes, I used Rufus. Pressing F12 didn't do anything.
