Hi again

Especially dear balder, is there a way to boot unbunto using ezboot (usb) directly into live mode (and option to install later using the included install desktop tool). I assume this will require editing some boot menu file inside the unbunto iso

Any suggestions?

thanks

OK, I found this main menu file named loopback.cfg inside the unbunto iso (grub folder):

menuentry "Try Ubuntu without installing" {
linux /casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=${iso_path} quiet splash --
initrd /casper/initrd.lz
}
menuentry "Install Ubuntu" {
linux /casper/vmlinuz  file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity iso-scan/filename=${iso_path} quiet splash --
initrd /casper/initrd.lz
}
menuentry "Check disc for defects" {
linux /casper/vmlinuz  boot=casper integrity-check iso-scan/filename=${iso_path} quiet splash --
initrd /casper/initrd.lz
}
menuentry "Test memory" {
linux16 /install/mt86plus
}

I need it to default on first option :Try without installing). How to make it default and remove the delay timer? I do not see any default settings here. Also' how to boot with ezboot from usb?

thanks

I haven't tested but test this ??? :

Open ISO-file (I used UltraIso) and find 'txt.cfg' inside folder 'isolinux'
It is part of this file that is used in 'kicker-image' to launch Ubuntu.ISO-file as it is
And to modify downloaded 'ubuntu11 kicker-image to have 'install' as well, you test this:

1. Extract text-file 'menu-lst' from floppy image 'ubuntu11.img'

2. Modify 'menu.lst' to also have text 'only-ubiquity' (look in text-file 'txt.cfg' to get a hint)

3. Save changes to 'menu.lst' and inject it back to 'ubuntu11-img'

4. Use 'Save As' to modified 'ubuntu11.img' and save image to folder EZBOOT using name 'install-ubuntu.img'

5. Use menu command in EasyBoot:  run install-ubuntu.img

6. Only tick 'Joliet' when creating ISO in EasyBoot

7. Use 'Burn' to USB in EasyBoot as usual
