Hello,

The situation is that I have a remote server with not physical access and not CD/DVD unit on it.

I want to be able to boot that machine from any LiveCD's ISO's. I suposse there must be a method to store the ISO on the HD and indicate the GRUB to boot from that ISO located in a partition of the disk.

Could you please help me on this?

Many thanks.

I would doubt that this is possible. Without loading some kind of operating system, there is no way to read the disk, or the .iso file even. What you might want to look into is a network boot situation. You should be able to configure the client to search for a bootable image from the network. You can set this boot option as the highest priority (above the HDD). Sorry I don't have any more information, but google might be your best friend in this case.

I don't understand why you'd want to do this? The guide you posted links to pendrivelinux... which has guides to put ubuntu 8.04 on a flash drive, so you can install directly from that, without going through all of the work to resize, mount, install, unmount, then resize again.

Just put the 8.04 CD on the flash drive and install from the flash drive. I've done it before and its very easy and fast for pcs w/o a cd drive.

you'd need to have a live OS into which you can ssh then... right?

Because I DON'T HAVE physical access to the server, it is on datacenter miles away.

Correct!!

All this doesn't work without a working OS. The idea is to boot a liveCD from a live OS.

If your remote system crash, you can order a new OS installation and do all steps again. Afterwards boot from your LiveCD ISO located on Hd and do an image restore to recover your old OS.

Are you able to install over the network?
Do you have access to a DHCP server that is on the same network segment?


If you have access to that, tftp server, you may install over the network just as easy.
