can you boot from an external hard drive

In those cases you have to edit the /boot/nf file and add the line: sharewait=15 underneath the aforementioned line (if it still does not work, try with a higher number like sharewait=20 for example). If you are using an external hard drive and it is not recognized correctly after doing this, then it might be that your external hard drive needs more time to spin up while Batocera boots. If the drive is empty, the folder structure for the ROM files will be created on next reboot. Sharedevice=DEV 2efa1068-yyyy-yyyy-yyyy-yyyyyyyyyy dev/sdb1 is the Batocera boot partition and /dev/sdb2 is the rest of the Batocera USB pendrive (that I don't want to use). In this example, /dev/sda1 is the partition on the drive hosting my ROM files. dev/sda1: LABEL='SHARE' UUID='2efa1068-yyyy-yyyy-yyyy-yyyyyyyyyy' TYPE='ext4' dev/sdb1: LABEL='BATOCERA' UUID='zzzz-zzzz' TYPE='vfat' dev/sdb2: LABEL='SHARE' UUID='12e46ca9-xxxx-xxxx-xxxx-xxxxxxxxxx' TYPE='ext4' It will output something similar to the following: The list of UUIDs of all drives connected to the system can be printed with the blkid command. This will be done by editing the /boot/nf file in the boot partition and providing the information of the partition that hosts the ROMs. Note that we’ll re-partition this drive, so backup any data that may already be on the drive as it will be lost during re-partitioning. Your target portable external hard drive (HDD, SATA SSD, M.2 NVMe SSD etc.). If the above steps aren't sufficient for your purposes, you can set up the external drive manually. Check that you can boot from this thumb drive on the computer you plan on working from. Write themes for batocera-emulationstation.
