10.10 usb install menu remove

On a usb install the 10.10 has normal grub and then goes to a menu choice to try or install. Can I get rid of that or put a default!!??

The USB Key is essentially a Live CD with a persistence image (an image file with a blank Ext3 file system on it that allows you to store files on the USB drive) and a different boot loader (syslinux instead of isolinux) and as such it will still have the Live CD Menu. If you remove it the drive won't boot.

Select the "Try" option and you'll be in the Live environment but still be able to save files to the drive. This is the default.

From that environment, you can then install to the hard drive using the same installer as on the CD.

Thanks for the reply but I did kind of know all that already.

What I wanted to do was get rid of the menu choice. I know why they did it, I just want to remove it.

It is like using a MS product asking me twice like that.

I noticed that if you hit F2 (or something) on startup, select English, then select "Try Ubuntu without installing" - then it doesn't give the "Install" prompt mid loading.

Looking at /cdrom/boot/grub/loopback.cfg,

Code:

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
}

How would I compare existing default and set this as default from a USB ubuntu?
(In a normal install with lilo, I'd just edit the /etc/lilo.cfg - but I'm not familiar with grub or usb/live distros)
