What is boot.ovh?
boot.ovh is a way to PXE boot various operating system installers or utilities from one place within the BIOS without the need of having to go retrieve the media to run the tool. iPXE is used to provide a user friendly menu from within the BIOS that lets you easily choose the operating system you want along with any specific types of versions or bootable flags.
You can remote attach the ISO to servers, set it up as a rescue option in Grub, or even set up your home network to boot to it by default so that it’s always available.
Download one of the boot.ovh bootloaders that works for your situation and start PXE booting your favorite operating system. The bootloaders are precompiled versions of the latest version of iPXE that will allow you to PXE boot into http://ipxe.boot.ovh. If you have DHCP it’ll automatically attempt to boot from DHCP. If you need to set a static IP address, hit the ’m’ key during boot up for the failsafe menu and choose manual network configuration.
If you already have iPXE up and running on the network, you can hit boot.ovh at anytime by typing:
chain --autofree http://ipxe.boot.ovh
