PXE (Preboot eXecution Environment) is a protocol used to boot a computer over a network, even if the computer's hard disk is empty or not yet initialized. It allows a computer to download a boot image from a remote server and boot it, instead of booting from local media like a hard drive or DVD.
To boot a DVD from a remote device using PXE, the following steps can be followed:
Set up a PXE server on the network, which can provide the necessary boot image over the network.
Configure the PXE server to include the bootable DVD image as one of the options for booting.
Configure the target computer's BIOS or UEFI to boot from the network using PXE.
Power on the target computer and wait for it to boot from the network.
The PXE server will provide the necessary boot image, which in this case will be the DVD image.
The target computer will then boot from the DVD image, as if it were a local DVD.
UEFI (Unified Extensible Firmware Interface) is a newer type of firmware interface that is replacing the traditional BIOS on modern computers. UEFI can be used to configure the boot order and boot devices, but it does not provide the capability to boot from a remote DVD image using PXE.
NFS (Network File System) is a protocol used to share files over a network. While it can be used to share files required for booting a Linux system, it does not provide the necessary capabilities to boot a DVD image from a remote device.
GRUB (Grand Unified Bootloader) is a bootloader used to load the Linux kernel and other necessary components during the boot process. While GRUB can be configured to boot from different devices and network locations, it does not provide the necessary capabilities to boot a DVD image from a remote device using PXE.
