I'm sorry if this is a duplicated post, but I've been looking for a week with no luck.
i wish to reinstall my laptop with tribe 5, but since beta and gold are a weeks away, I dont want to burn a CD.
my CDRW are of 650MBs, and my 2 DVDRW are scrashed.
So I would like to do what is called an HD install, that allows me to boot (using a modified grub) from the contents of the alternate iso or a bunch 
of locally downloaded packages.

I've tried the procedure here:
[url]https://help.ubuntu.com/community/Installation/[/url]
but no luck

the contents of the iso are on my /home partition:
[CODE]$ ls /home/gutsy/
-rw-r--r--  1 bugabundo root 239M 2007-09-11 23:09 boot.img
drwxr-sr-x 10 bugabundo root 4.0K 2007-09-11 15:25 disc/
-rw-r--r--  1 bugabundo root  15M 2007-09-11 23:09 initrd
-rw-r--r--  1 bugabundo root 1.7M 2007-09-11 15:30 vmlinuz
[/CODE]
those were download from the hd media page:
[url]http://archive.ubuntu.com/ubuntu/dists/gutsy/main/installer-i386/current/images/[/url]

here are a few tried I made on grub:
[CODE]title		HD instal
root		(hd0,4)
kernel		/gutsy/vmlinux root=e3740d46-69f9-4a4b-8f5c-707d262369a4 ro verbose
initrd		/gutsy/initrd
boot

title		HD instal 2 
root		(hd0,4)
kernel		/gutsy/vmlinux boot=casper root=/dev/ram ramdisk_size=1048576 rw
initrd		/gutsy/initrd

title		HD instal 3
root		(hd0,4)
kernel		/gutsy/vmlinux root=/dev/ram ramdisk_size=1048576 rw
initrd		/gutsy/initrd
boot[/CODE]

any help appreciated.
