View Full Version : [ubuntu] Can GRUB boot a frugal Ubuntu Installation?

I have just installed Ubuntu to my flash drive and I am putting grub on it as well so that I can choose between a couple of different OS's to boot off my flash drive. I can not figure out how to refer to the frugal, or usb, installation of Ubuntu in grub. Does anyone know how to do this?

PS: I am sorry if this is posted somewhere else on these forums, but I looked for a long time here, and all over the internet for a solution and could not find one.

Thanks,
Kaleb

So what method did you use to install Ubuntu to your flash drive? Also, when it comes to booting issues, a good place to start is to download the Boot Info Script to your Ubuntu desktop (can be a Live CD desktop):

https://sourceforge.net/projects/bootinfoscript/

Then open a terminal (Applications > Accessories > Terminal) and do:

sudo bash ~/Desktop/boot_info_script*.sh
That will create a "RESULTS.txt" file in the same directory from where the script is run, namely your desktop; please copy/paste the contents of the RESULTS.txt file to your next post, highlight the copied text, and click the pound/hash sign "#" graphic button in the Ubuntu forum message box so that the text will get "code" tags put around it. The results of that script will help clarify your setup and hopefully what it might take to boot your OSes on your flash drive.

I used the usb installer (System > Administration > USB Startup Disk Creator).
I haven't finished setting up the grub menu.lst file yet. So far, I just copied it from my hard drive install and changed the first entry in attempt to make it bootable.

Here are the results of the Boot Info Script:

============================= Boot Info Summary: ==============================

=> Grub0.97 is installed in the MBR of /dev/sda and looks on the same drive
in partition #5 for /boot/grub/stage2 and /boot/grub/menu.lst.
=> Syslinux is installed in the MBR of /dev/sdb

I know. You need to use the majic "iso-scan" boot parameter. First, extract the kernel and initrd from the ISO. Then, put all three files in some directory. Finally, add something like this to menu.lst:


title Ubuntu 9.04 i386 (from ISO)
kernel (hd0,2)/fromiso/vmlinuz iso-scan/filename=/fromiso/ubuntu-9.04-desktop-i386.iso boot=casper quiet splash
