I didn't say it doesn't work. I said that it wouldn't work if you didn't prepare the ISO correctly. I said that you cannot take any random ISO and make it UEFI-bootable just by running isohybrid -u on it.linuxcbon wrote:many distributions use it and it works...So why doesnt it work for you ?
You can. As I said, download any non-UEFI puppy.iso, then try to run that "isohybrid -u" on the ISO. See what message you'll get. You don't even need to get to the step of attempting to boot it. I can copy and paste the message I've gotten when *I* do that, but then if you believed everything I said from the beginning we wouldn't have this conversation, do we?(I cant test, I dont have any UEFI, so I will let other people test it).
But you are right to question me. Don't take anything you hear for granted. ...BarryK wrote:Ha ha, have run into a problem with using the full 'tr' utility from 'coreutils', see my blog report:

I'm currently playing with isohybrid, and have had partial success.
I used 'dd' to copy the .iso file to a flash drive, and booted on my baby laptop.
If you use "isohybrid -u" to make it bootable on flash, and the boot from flash is the UEFI boot (not BIOS boot), then yes, the iso will probably boot on optical drive too.jamesbond,
What do you think? If my iso will boot on a flash drive, is that a pretty good indicator that it will also boot on an internal optical drive?
What do you use for making the ISO? cdrkit's mkisofs is not a good choice. Use either xorriso, or cdrtool's mkisofs. I had to use blackmagic too when I still used cdrkit's mkisofs.Note, I had to do some black magic to get my UEFI-firmware to recognise the esp fat image file 'efiboot.img' that I created in the iso.

Yes, this means it works. Do you use grub2-efi, or still the syslinux-efi? If you use syslinux-efi, you need to keep two copies of vmlinuz and initrd: one in the iso-root (for BIOS isolinux), another one inside efiboot.img (for syslinux-efi). If you use grub2-efi you only need to keep one copy, in the iso-root.I then used 'dd' to write the iso to a USB stick, and hey, my baby laptop recognised it, even (started) to boot -- it loaded vmlinuz, but I haven't yet put an initrd into it. One step at a time.
You need to get hold of woofQ. I plan to upload it after releasing Quirky 8.0. Might upload woofQ as a tarball, as an alternative to my Bones version control system.slavvo67 wrote:Hi BarryK:
If you are going completely back to the .iso standard, can you possibly repost in more detail how you create the usfs.xz files in the past? I tried to follow your previous posts about it but failed to recreate. Perhaps a walk-through?
Much appreciated if you could take the time.
Best,

OK, got it.jamesbond wrote:If you prefer gummiboot, the bootloader is attached. For example of how to use it, I've uploaded the FAT image here: http://www.lightofdawn.org/g.img. Use this g.img instead of efiboot.img and quirky will boot.
Note: let me know when you've grabbed this g.img. I'll remove it after that.
