I would like to have a setup like this: boot manager tries to boot from usb device, if it's available - it just boots, but if some error occurs (=no usb drive present) it automatically loads from "fallback" device, such as partition on hdd. Sadly, my BIOS don't give me such an option, after USB device is removed it forgets about it completely, including boot order settings. Is it possible to achieve this with plop boot manager?
No, thats not possible.
Thank you for the answer! And thank you for developing and maintaining this brilliant boot manager!
Such a boot sequence is planed for PBM6, but currently the development is stopped for another project. Maybe a small update comes soon, but this will be only a driver update.
