I'm looking for preferably free/open source solution for booting from network. What I need to do is:
- Have a boot manager check specified folder on a server.
- If there's a file named f.e.: "image.img", then the manager will boot from it. The image contains a disk cloning tool which will back-up/restore the hard drive.
- If the file doesn't exist, boot from hard drive.
What I'm trying to achieve is that the only thing I need to do in order to run the disk cloning software is to put a file into a special folder on the server. I have to manage 50 computers in an internet cafe, and running the disk cloning tool from a thumb drive is a real pain.
I was thinking about a lightweight linux distribution, but my knowledge is very limited when it comes to linux.
