Gotcha. I think the problem is its not seeing your usb drive in general....or does it?If your usb drive is mounted before you want to install then unmount it,and then see if the installer sees it.
well when I boot into 2.3 it does !
this time booting off the 2.4 dvd it does not auto mount them-the partitions on the usb drive
I check with gparted and they are not mounted
so I ran the install and same problem-it only sees the laptop drive
so I mounted the ext4 partitions on the usb drive and as soon as I started the install they got unmounted
?
is it possible to make another iso with the old grub ?
I am sure I am not the only one who has a Linux install on a USB drive
Thanks for the help but till I can get this solved, looks like I will be staying with 2.3
