Boot From USB on a Bios That Doesn't Support It

This instructable is my second, and is VERY useful when you have a bootable flash drive. It shows you how to create and use the PLoP boot manager.

----------You will need----------
A computer (doesn't need to be windows)
A flash drive with an OS installed on it.
CD writer
CD burning software capable of burning iso's

Once you have those, continue to the next step!

Step 1: Download PLoP Boot Manager and Extract

You can download the PLoP boot manager from this site:
Download PLoP Boot Manager

Once you have the zip file, extract it to anywhere accessible.

It should be a folder with some files.
You should only worry about the plpbt.iso file.

Step 2: Burn the File to the Disc

Burn the plpbt.iso file to the disc.
Once it is done, the disc should look like the picture below.

Step 3: Boot From the Disc

Next, you need to put the disc in, and restart the computer. Some computers have a different boot sequence, so you might need to change it. Just press F2 when the computer starts up, and change the boot order or boot priority.

When you have the CD booted, it should look like the picture below.

Change the option to USB, plug in your flash drive, and hit enter.

This is the end, my friend, of my instructable.

    Most excellent. This is a brilliant find and instruction. My old laptop is going to be used once again. Thank you

    Thanks! I was looking for something like this.

    What about using this method with a floppy instead of a CD? The ISO file is the killer, but maybe burn a CD with the ISO then transfer the files to a floppy? Would be great for old computers with a floppy, no need to mess with boot order to begin with. Surely the files in the ISO aren't too big for a floppy -- it's a minimal boot and use old guys used to boot from floppies all the time! Even Windows 98 had a rescue floppy boot option...

    To do that...I believe you would lose the boot information in the ISO. The files on the ISO are executed by the boot loader, which happens to be the first 512 bytes on the CD. I don't believe you can just "copy" the files to a floppy, but there is a way to put it on a floppy.


    I've been looking for a solution like this for a while. When I found one that worked, Instructables time!
    I hope that this all works for you as it has worked for me.

    This is the end, my friend, of my comment.


    I have been using Plop to do this for awhile.  You can indeed put it on a floppy, which is how I do it, but you have to make sure that you write Plop to the floppy as an image, not individual files or it will not work.  Also, you will need to use the Plop menu to try different driver configurations, as the default will not always work.

    No, you should be able to use a microscope and see all the data as his picture show!
