I have a 128MB stick.  the bios treats it as a hard drive.  When i go to select a boot device, the usb stick shows up under hard drives as a usb drive.  I tried installing plop but it didn't boot from it.  The next smallest usb stick I have is 16GB, then 32 and 64.  The bios doesn't see those at all.  I have a cd to boot plop from if I can't make it boot via grub.

thanks

there may be a way I can check tonight normally I burn Plop to a cd boot the cd and the plop menu will offer up usb options to install I also suspect your bios can boot to usb directly but usb options will only be shown if the usb is plugged in and and sometimes shows up as a harddrive not a usb also check as usb devices are often disabled by bios as a boot option by default sometimes are well hidden in menus and hard to find

    My system normally boots from /dev/sdd1.  I've installed Plop to
    /dev/sda1. If I switch on the machine and press F12 to select a boot
    device, then pick /dev/sda1, Plop loads.   When I installed Plop, I
    chose the MBR of /dev/sda1.


    Is there a way to put a menu entry in Grub2 that would tell the
    system
    to boot from /dev/sda1?


    I did manage to create a menu entry in /etc/grub.d/40_custom that
    lets
    me load plop, but when I do, it gives me a warning that I can't save
    changes.  Is there a way to fix it so I can save changes? Here is my
    40_custom file.


    #!/bin/sh
    exec tail -n +3 $0
    # This file provides an easy way to add custom menu entries.
    Simply type the
    # menu entries you want to add after this comment.  Be careful not
    to change
    # the 'exec tail' line above.


    menuentry "Plop bootloader" {
    insmod ext2
             set root='hd3,msdos1'
             if [ x$feature_platform_search_hint = xy ]; then
               search --no-floppy --fs-uuid --set=root
    --hint-bios=hd3,msdos1 --hint-efi=hd3,msdos1
    --hint-baremetal=ahci3,msdos1 15d4e39e-2e6c-4ee4-9a24-67fd9ccab8f9
             else
               search --no-floppy --fs-uuid --set=root
    15d4e39e-2e6c-4ee4-9a24-67fd9ccab8f9
             fi
             linux   /boot/vmlinuz-4.15.0-47-generic
    root=UUID=15d4e39e-2e6c-4ee4-9a24-67fd9ccab8f9
             linux16 /boot/plpbt.bin
    }
