How do I use GRUB to boot directly off of an iso? I have a ubuntu 7.10 ISO (Gutsy, I do not want to upgrade to Hardy yet), but my old lappy that I found in the garage recently has no CD drive, and I cannot get it to boot off of our external DVD drive, it apparently cannot boot off of any USB device. I know it is possible to do this, I have just not found a good tutorial. I used grub to boot an installer, but it needed to download the file, once I booted off of it, and it could not detect my internet connection, and I tried both wireless G, and ethernet. I am running Windows 98SE on a Toshiba Sattelite 1730, with 192MB RAM, 700MHz Proccesor, and a 10GB HDD, although I have 3.75GB worth of SD cards that I can use if I need to. I have GRUB, already, and I know how to modify it. I found this lappy in our garage, and once I bought a new power cord, it works fine, except for a few flaws, one being the CD drive does not work. oh, and I do have a floppy drive, and a spare floppy, if I need one, but I have ne experience using one, and if I need to do something with it, you will need to dumb it down as much as possible. Any help will be appreciated, I don't really care how, I just need to boot the ISO without using any external devices. Oh, and if you know how to fix the internet problem in the ubuntu install thing, that would work, too. Ideal situation: Someone provide me with a couple files to download, where to put them, and a string of code to enter into the menu.lst file.
Oh, and partitioning part of my HDD to act as a make-shift CD drive is not an option. I cannot partition my drive without booting off of an ISO in the first place, as Windows 98 does not have the capability to partition the HDD it is currently using.
Thanks in advance!
