What to do about machines that don't support USB booting?

    I tried the Plop Boot Manager on 2 computers that did not have an option to boot from USB in the BIOS. The Boot manager came up and I was able to select the USB drive, and it seemed to start booting Cloudready, it either just hung, or rebooted the computer, so.

    When I get a computer that I can boot from USB, I will try swapping the drives and try these computers again, but I suspect that you might be right that if they can't boot from USB, they are probably too old to work with Cloudready.

    I was able to get 2 other computers up and running with Cloudready and it works fine.

    I have a Toshiba Satellite that can boot from a Fedora Live USB, but won't boot from the CloudReady USB. I've used the same CloudReady USB to successfully install on a Vaio. Thoughts?

    Given that I have Grub2 on the Toshiba, I tried a workaround by running grub2-mkconfig and it is able to create a menuitem to boot from the CloudReady USB, and this does boot. I then tried manual install, but postinst was missing cros_legacy / cros_efi, so I tried adding these to the boot menuitem. Now manual install completes, but the Toshiba still can't boot from the HDD. Thoughts?

    Hi Peter,

    Have you re-tried the USB on your Vaio, just to be certain it still works?

    Once you've done that - you should check your HDD settings for any kind of UEFI mode, and even consider seeing if HDD mode (AHCI/IDE) has an effect.

    If you have further questions I'd request that you open a new thread to discuss this further.

    It seems it boils down to the Toshiba bios not recognizing GPT partitions. I don't have Windows on the machine, so I guess I have to make a DOS boot disk to try upgrading the bios.

    In the meantime, I tried manually creating a dual boot setup by installing Fedora on MBR partitions and then manually duplicating the partitions on the CloudReady install stick, but it detected something amiss and went into a repair loop. For now I'm punting and just using Fedora, but I'll post back if I try again.

    I managed to boot CloudReady on older Mac having the same problem - using Plop in USB1.1 mode. It works very well but booting is too complicated. My guess is old Macs use UEFI32 which is not supported by CloudFlare?

  • Forrest Smith

    CloudReady has UEFI32 support, but it requires that you specify a specific EFI file to successfully boot. The boot path is:




    Typically, machines will default to:




    On a mac, it may be a challenge to manually specify the right file, since there's no UI for configuring such things.

    You can try using something like:


    etcher.io (you'll need to rename chromiumos.bin -> chromiumos.iso)
