If you can install from it, you can mount it (think about it) - perhaps you need to be root? >>>> >>>> d-i knows how to mount the ISO (otherwise all your installs would have >>>> failed).

Then you should have used cat/cp to tranfer the *data* instead of dd to *duplicate* the *slice* (file system, boot sector, and data). Refer to the post from the maintainer/author of the cd creation software for more (authoritive) details. Your goal, with the now stated "presumption"/implementation is achievable using GRUB. Copy the isos to the FAT/UDF(see further down this post) Flash key - then install GRUB - then edit GRUB so it boots the first iso *image* (the first Debian iso from each release is bootable). Then you can boot from a FAT/UDF formatted Flash key - choose the iso from the GRUB menu and begin the install, during the install you'll be able to add additional CDs (negating the build-one-massive-cd-from-multiple-cds-step). > >> >> Have you tried mounting the key "-t iso9660" or udf? > > No. See "unstated presumption" above ;/ I guess your missing my point - if you dd an iso file system to a drive it (the drive) will then have the same (bit perfect) file system as what you dded. i.e. if you dd an ext4 file system the drive you dd it to will also have the *identical* ext4 slice, likewise with an iso9660 file system. > >> >> NOTE: d-i will "see" the Flash key as an iso image if my understanding >> of what you're doing is correct - which means it's already mounted when >> you try and "view the files".

Nor did my Squeeze install with Gnome2. Simple test - if the Flash key is /dev/sdb try (as root):- mount -o loop -t iso9660 /dev/sdb /mt;ls /mnt > >> >> Have you considered just formatting the key with ext and copying the >> install isos to it - then using GRUB to make it bootable? > > I would want FAT so I could exchange data with my WinXP machine. That'll work. Although... FAT16/32 and the other versions have limitations. May I suggest UDF. WinXP needs a driver (from MS) installed - but it will then recognize UDF - that'll free you from slice size limitations. <snipped> Kind regards -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
