Hi all, I have a USB pen drive where I've installed grub and copied on it some iso images of linux distributions and I have configured grub to boot them directly. I've tried booting puppy linux 5.25 iso image but I get the error lupu_525.sfs not found. But I can find it on the iso image! The iso images are all on the root of the pen drive and this is the puppy relative portion of the grub.cfg:

menuentry "Puppy Linux 5.25 k 2.6.32 " {
loopback loop /lupu-525.iso
linux (loop)/vmlinuz iso-scan/filename=/lupu-525.iso
initrd (loop)/initrd.gz
}

Have you any idea how can I configure grub.cfg to boot the iso directly?

Thank you very much

Some Linux ISO's can be booted directly, but Puppy is not one of them. Because the lupu_525.sfs file is buried inside the ISO, Puppy can't find it.

However, if you extract that file from the ISO and copy it to the root of the flash drive, it may boot.

[edit] But that might not work either, because Puppy usually requires the "pmedia=usbflash" argument to boot off a USB device.

Also, read here.

Maybe this,

Change the initrd line to this:
initrd (loop)/initrd.gz iso-scan/filename=/lupu-525.iso

To boot a Puppy from GRUB2 on a flash drive, it may be simpler to NOT use the ISO.

Make a folder like /lupu525 and copy the three core files from the ISO - vmlinuz, initrd.gz and lupu_525.sfs.

Use the following GRUB2 entry.

Hiren's method is good.

Won't boot >> from ISO

but extract with 7 zip.
