Oh
what do you mean?

you can put it on usb/hd or cd

what info do you need?

basically, netbootcd uses kexec to change form it's kernel/initrd to whatever your downloading

it boots up and asks what distro you wanna install
like deb or fed

it then downlaods the kernel/initrd and installer for whatever sustem and starts the install process

Hi,

You can use the PXE,USB methods or alternate sources as I suggested. Any way you will still need to boot the installer in some way.

Another way would be source on a VM on another machine via the network if you don't want or trust access to the HOST. But if things on your LAN are that bad or untrusted then other things must be addressed.

I'm curious, what exactly are you wanting to do with this moving target? I reread the OP again and I think the original problem was the inability of booting you installer to load from the ext hhd(source). The lack/problem here was that you installer did not recognize the source. Possibly because the kernel was not aware of the device type or USB had not settled.

Multi-boot DVD

okay I finally had time to read though http://pcquest.ciol.com/content/ente.../105070101.aspproperly

as I read it you can follow the instructions at http://pcquest.ciol.com/content/ente.../105070101.aspto make a Multi-boot DVD image than follow the directions at http://en.opensuse.org/SuSE_install_from_USB_drive to make the image boot from external hdd

====

It just accord to me that if you extract the dvd to a folder you may be able to load miniroot.gz, vmlinuz? from grub

I am short on time right know otherwise I would try to be more helpfull

I have finally installed grub2 into my external HDD. It sucessfully boots to the grub prompt. I have not written the grub.conf file yet.... since i just want to test if it works... its not mandatory to have a grub.cfg file is it??

this is what i did:
Code:
grub>loopback loop /OS/ubuntu 9.04/ubuntu-9.04.ISO
that should create the loop back device "loop"

Code:
grub> chainloader (loop)+1
This is supposed to chain load the loop device. However this gives an "invalid magic number" error.

The "multiboot" "linux" or "initrd" grub2 commands gives either the above error or an "invalid signature error"

The external HDD is formated as NTFS to store DVD images... but since grub can access the partition without problems... NTFS cant b the problem or can it??

Any idea what these errors are???

Note also brother that grub2 does not let you edit the grub.conf manually
or at least thats what it says

also, did you see this?
http://www.panticz.de/MultiBootUSB

note also that grml, sidux and some others can boot from iso with regular grub

Yes, i did see that post... thats where i got the idea of this loop back device from....

We can edit grub.cfg manually, though the commands n overall format of the file is different from that of grub legacy's grub.cong/menu.lst
