Today I was faced with the challenge of installing Windows Server 2008 R2 on a server with only a CD ROM drive. I created a bootable USB drive and loaded the installation files on it like I normally do but I could not get the server to boot from the USB drive no matter what I tried. Finally I found the solution with a little bit of searching. There is a boot manager called plop that can run off of a CD or floppy drive that will let you boot your USB drive.
These instructions will allow you to boot a USB device when your BIOS does not support USB booting.
- Download the boot manger from plop’s website.
- Open the file and find plpbt.iso and burn that image using whatever burning software you prefer (I just used the built in Windows 7 one).
- Connect your USB drive to the computer and insert the plop boot manager disc. The bootmanager will load* and allow you to select your USB drive from the list.
