Heaps of Roadblocks - Trying to boot from USB

[ThrowOutWindow]

I am attempting to boot from a USB drive on my old Toshiba laptop. I wish to install a newer version of Windows or a Linux distribution such as Ubuntu. The computer is very slow and I would like to reformat the whole thing and installed something else. I am making the bootable USB drive using Rufus.

Roadblocks:

In order to be able to boot from a 'MBR partion scheme for BIOS or UEFI-CSM' bootable USB drive, I must disable 'Secure Boot' in the BIOS options of the laptop. The problem is that no where in the BIOS is there a a setting for this. There should be a 'Security' tab that would have these options but it is not there.

The other option would be to create the USB using MBR or GPT for UEFI, but no matter which disk image I try to use, Windows XP, Windows 7, Ubuntu 12.04/14.04/15.10, none of them work. Rufus simply says: "Unsupported ISO: When using UEFI Target Type, only bootable ISO images are supported. Please selected an EFI bootable ISO or set the Target Type to BIOS".

I cannot find a way around this no matter what I try. The two solutions I know for getting this to work do not work themselves. I need to either disable 'Secure Boot' in the laptops BIOS settings or make a GPT-UEFI bootable USB drive.

Edit: I would not consider booting from a DVD/CD to be a solution to the problem. Booting from USB is the goal.

An old Toshiba laptop would not have a secure boot option in the bios, so there`s no use looking for it.

An old laptop would not even have a UEFI bios.

Your problem is something else, there is no reason you can`t use the boot menu to boot from a properly prepared usb stick.

Just enable Legacy mode in the bios if it indeed is a UEFI bios and create a normal usb installer for a MBR disk.

USB-FDD Legacy Emulation is Enabled in the BIOS. The USB drive boots fine on another machine. I made it using the 'MBR partion scheme for BIOS or UEFI' in Rufus. I changed the boot order on the laptop to FDD>HDD>CD-ROM>LAN but it does not boot the USB. I have tried all USB ports. The BIOS is 'ACPI BIOS version = 1.10'. I do not know what to do

Edit: In the Boot Options menu, there is 4 graphics to choose from: 3 stacked CDs, 1 CD, 1 Floppy, and 1 LAN option. I have tried all of these and all end up booting to the HDD.

We had an old Packard Bell that wouldn't boot from USB. I know you said don't suggest dvd but that's the way I would go.
