Multiple - boot from ISO files does disappoint OS food selection

I made use of instructions from PenDriveLinux.com to create a numerous - boot USB drive with some ISO photos on it. I made use of Xubuntu 10.10 Desktop photo and also a Linux Mint 9 XFCE photo. I had the ability to boot either of both running systems. Every one started straight to the desktop computer nonetheless.

If I boot *Ubuntu from an ISO photo which has been "melted" to a CD or a USB, I exist with a food selection motivating me to install or attempt the OS, examination memory, etc

Why does booting from the ISO go straight to the desktop computer, whereas the various other method offers the OS food selection first?

Update

menuentry "Ubuntu 10.10 Desktop ISO" {
 loopback loop /ubuntu.iso
 linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu.iso noeject noprompt splash --
 initrd (loop)/casper/initrd.lz
}

It results from the bootloader arrangement on the possibly - multi - boot USB drive. The Grub configuration for the drive is set up too the numerous OSes straight: it has access like

menuentry "Ubuntu 10.10 Desktop ISO" {
 loopback loop /ubuntu.iso
 linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu.iso noeject noprompt splash --
 initrd (loop)/casper/initrd.lz
}

Such an access boots straight right into the shown os, bypassing the bootloader inside the ISO.

I assume it would certainly be feasible to switch over to a various configuration documents with configfile (loop)/path/to/grub.cfg, if the bootloader inside the ISO is additionally Grub2 (which is not so usual on CDs). Filling the bootloader inside the ISO would certainly be hard, as the bootloader would certainly need to recognize where to locate its parts.
