Maybe you can help me once again. Couple of weeks ago I asked for help on setting up my Raspberry Pi 3b with an external SSD drive. With some help from here I got it working as webserver. WordPress complained about a missing component (bcmath), so I installed that with sudo install php-bcmath (I think this was the command, but not sure). After that installed I did a reboot and that was the start of problems. The Pi didn’t boot anymore. Tried placing the sd-card and boot from there. That did work. Wa happy and hoping it would be a matter of minutes before everything would work again. The Pi only boots with SD card installed, so I first tried to see if the OTP switch was set, and in dietpi-config I see that USB support was set to ‘On’. Then I did a check to see if the SSD drive could been ‘seen’ from the Pi it self with lsusb, and that also was the case. root@WebServ:~# lsusb Bus 001 Device 004: ID 1058:2642 Western Digital Technologies, Inc.

(formerly SMSC) SMC9514 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub root@WebServ:~# (btw when using a powered USB-hub it doesn’t work) So, next I tried to once again boot from USB, and waited for about 40 -45 minutes, but to no avail. Would #3 on this [post](https://dietpi.com/forum/t/raspberrypi4-rpi4-upgrading-from-existing-sd-card-setup-to-boot-from-ssd/4555/1) be able fix this? --- _[View the full topic](https://dietpi.com/forum/t/no-longer-booting-from-ssd/5920)._
