Network boot iso

All of the boot service entry points are ordered according to the configuration specified in the BIOS. It is quite common that the user is given a choice of which boot service to try first by pressing a hotkey. F12 is a common key to start a boot service offered by a network card, but this varies among manufacturers.

Once the first boot service has been selected, either manually or automatically, control moves to the next step. Start first boot service in BIOS boot services list During this stage, the program indicated by the boot service entry point is started.

At this point, control passes to the boot service program, which starts its discovery process for a boot program. Boot service performs discovery for boot program Different boot services go about looking for the boot program in different ways. A floppy controller will read the first sector of the floppy and get ready to start that piece of code. If a location is advertised, a TFTP request is performed to fetch the boot program, commonly referred to as a network boot program NBP.

If the boot service was unable to find a valid boot program, the boot service will exit and control returns back to the BIOS, which will try the next boot service. If a boot program was successfully found, control will be handed over to it. Remove first boot service or put at bottom of list The BIOS needs to cycle to the next boot service in its list.

Both methods have pros and cons. The next step is to figure out if there are any more boot services to try out. More boot services available? If there are more boot services available, the next one in line will be started. If there are no more boot services the computer will halt and perform its halt operation. Also, once the machine has booted into the Ubuntu live session, it is possible to perform the OS setup like you normally would.

The immediate up shut of using Ubuntu over the network, is that if your already using the CD version, you will never again be looking for the CDs you forgot in the CD drives. How does it work? In general the Ubuntu LiveCD boot process that we all know is like so:. For such an act, we can only say thank you to the Ubuntu team. The first step is to make the Ubuntu files available on the server.

You may opt to simply copy them from the CD drive, or extract them from the ISO, and that will work just fine. With that said, we will make the ISO auto-mounted.

With the above said, This author likes keeping a couple of past versions around, until the new one has been proven absolutely stable and issues free. That is why we will make a sub-directory and mount point according to version, but know that you could bypass that to have your single point of update. Note: Despite representation, this is one unbroken line. Test that the mount point works by issuing: sudo mount -a.

As we are basing this guide on our FOG server, the NFS components and some configurations have already been done for us by the FOG team, and all we have to do is add to them our Ubuntu share. At this stage we suggest you take the time to review some of the things you can do with this outstanding tool:. Ubuntu is everything, all that once was and all that will be, Ubuntu controls time and space, Love and Death, Ubuntu can see into your mind, Ubuntu can see into your SOUL!!

One of the great benefits to answering questions is the research process. You do tend to learn stuff, and that is good. Do these techniques work for any bootable ISO? Or do they only work for linux distributions?

Hopefully someone actually tries it and comments! The way to accomplish this on the two types of systems is very different. For simple systems For simple systems, you simply load the image ISO into RAM, and trick the system into believing it is an actual unit. For complex systems Modern systems with fancy stuff like good memory management and proper hardware detection pretty much ignore anything the BIOS has to say. The outline is: Have a Windows 7 install on a shared folder on the server Have a full Windows PE environment on the server in your TFTP root Have the client machine load the WinPE over the network and press F12 to get a command prompt Map the shared folder with the Windows 7 install to a drive letter Start installation from the mapped folder I have never tried this, and it seems it doesn't work for some people.

When would you use this?
