• Grub4DOS is a boot manager that can be easily installed to a flashdrive or hard drive. It allows booting multiple operating systems directly as well as booting into bootable partitions. For the purpose of this guide, Grub4DOS will be used to setup a flashdrive to boot the Acronis Resuce Media.

I have had no problem installing Ubuntu desktop when I boot off a live USB, but the server version has given me some trouble. I think it has to do with the way GRUB handles drivers. When the server install tries to look from the CD it can't find it.

I use the following to load it:

Is there any way to pass the location of the ISO to Ubuntu?

It's awfully simple:

1. Set GRUB4DOS to boot from ISO, (which is what you probably done already)
2. When Ubuntu Installer complains about no CD-ROM select go to shell console option,

3. Use a set of commands like this one:

4. Go back to installer and enjoy

Hope it helps somebody.. I've spent lots of time looking for this solution, until finally coming to it by myself.

I just installed ubuntu 12.04 server with Vaxquis' trick in USB with grub4dos.Apparently the server version dose not support cdrom-detect and iso-scan in installer. So we can ignore that part. Here is my config:

WHen you get CD-ROM detection errors, just 'Continue' twice back to Installer Main Menu.press ALT-F2 to console. Dragon age inquisition cheats engine. Type in:

press ALT-F1 back to Installer. Continue on 'Load installer components from CD'

note: you can use file=/cdrom/preseed/ubuntu-server-minimal.seed to install a smaller server or remove the whole 'file=..' part to select components manually. If you don't have enough memory to load entire iso to memory, remove ' map --mem /ubuntu-12.04-server-i386.iso (0xff)' from config. To avoid 'error 60', better format USB with 'mkfs.vfat'(e.g. mkfs.vfat /dev/sdc1) and then copy the iso file to it as the first file. Then copy bootlace.com, grldr[.mbr] and menu.lst to USB and run

Have you tried installing Grub on the USB and tell it to boot from your ISO? I'm not sure with server edition, but I have been using and installing Ubuntu desktop this way.

EDIT: I have just tried this and it doesn't work. I'm leaving the answer here just to keep track of things. Just don't downvote me please ;)

Here is the entry in my /boot/grub/grub.cfg on the USB

If you want to install an Ubuntu 10.10 Server from an USB Key, you might want to try 'Unetbootin'.

Download an Run it, select your iso file and it will take care of installing GRUB and copy the files over.

This is a PITA to handle manually. I just recently found Multiboot USB for Ubuntu and it works like a champ. You can feed ISOs into it and it takes care of creating the syslinux menu and all.

It is a French program, but there are English instructions here.
