Booting installer from iso (with GRUB)

[ghaspias]

If have these entries (some work , others don't). (hd0,1) is a ntfs partition where I keep the isos.

menuentry "Ubuntu Lucid netbook 32bit" {
 root (hd0,1)
 loopback loop0 /ubuntu-10.04-netbook-i386.iso
 set root=(loop0)
 linux /casper/vmlinuz root=/dev/sda1 loop=/ubuntu-10.04-netbook-i386.iso file=/cdrom/preseed/ubuntu-netbook.seed boot=casper iso-scan/filename=/ubuntu-10.04-netbook-i386.iso quiet splash --
 initrd (loop0)/casper/initrd.lz
}

menuentry "Ubuntu Lucid beta2 32bit" {
 root (hd0,1)

}

}

If someone can get Fedora running please share...

... also, did you consider using
usb-creator with a disk image (instead of a real usb device)?
Then use the method above to boot it.

This is the bug you are looking for: https://bugzilla.redhat.com/show_bug.cgi?id=557426

Fedora has some issues with multi-boot usb scenarions, but we will soon have an answer.

You can mount fedora iso and copy fedora files to a special folder and then use standard boot methods.
