Raspberry Pi Asked by 100pxsquared on December 28, 2021
I know of two methods to do this which I’ve tried:
I tried the imager method first and got as far as changing the partition lable for the sd card, rebooted, and was hit with an error along the lines of CPU 0 not supported
I then tried the BerryBoot method (which is where I am now), the steps I’ve done so far are as follows:
I’ve tried reinstalling BerryBoot and rebooting multiple times, however it always freezes until unplugging (I left it for a couple of hours to be sure).
It also seems to completely "disconnect" my peripherals as my mouse has RGB and it turns off when BerryBoot freezes.
Edit:
I’ve found and tried a 3rd method, official raspberry pi os USB boot support.
I’ve used this guide to get as far as booting from the SSD without the SD card inserted, at which point I was hit with the following errors:

Note: I did not use this method to try and boot Ubuntu
Edit 2:
I’ve been trying a different method using BerryBoot which has worked the best so far.
I’ve managed to install Raspbian 2019.10 using BerryBoot’s downloader/installer on first time setup, and after about 10 min on the edit menu screen it works. I’m now attempting to replace the Raspbian install with Ubuntu 20.04
(I think the problem may have been that BerryBoot crashes when loading the edit menu if no OSs are detected)
Edit 3:
Neither Raspbian nor Ubuntu boot from BerryBoot, the OS loads, but gets tonnes of errors and doesn’t finish booting.
I managed to successfully install Ubuntu on two separate ssd / usb drives and boot my Pi 4 from it. I find this guide to be quite good.

Make sure to follow the instructions carefully, especially the part where you update your Pi's EEPROM since it can break your chip.
Feel free to ask if you have any questions.

I was finally able to get Raspbian to boot from USB using official boot support.
It was either luck, or because of the drive enclosure chipset.
I found this page which details that certain chipsets don't work, and only listed one good one.
However further down the page there's a section on fixing (some) adapter problems using quirks, which involves editing /boot/cmdline.txt and adding an entry at the start like this usb-storage.quirks=XXXX:XXXX:u, where the X's are replaced with the ID of your adapter (which you can find using sudo lsusb, see the linked page for details)
I'm not sure whether this was the fix or not but it did work after doing this.
(FYI my adapter is a JMicron Generic SCSI Disk Device)

this thread may be helpful getting you up and running. if you read the entire thread it is apparent that at this point in time your mileage may vary.
RPI4 Direct USB Boot Ubuntu 20.04
I was able to follow the instructions and get everything up and running, and actually seemingly pretty stable. However, once i ran sudo apt update && sudo apt upgrade Ubuntu had issued an update to their firmware which replaced my *.elf and *.dat files, which in turn required me to re-copy them over to the USB drive from my laptop where I had the working ones backed up. That's when things seemed to go wonky on me and i began having a number of device-level problems.
I have since moved to the Raspbian 64-bit Beta and haven't had any problems so far. I plan to stay there until Ubuntu gets its USB boot issues sorted out, which seems like it may take a few months from now (25 July 2020).
Either one you choose, you will need to be sure to set your Pi to the "stable" channel for firmware, and you have the 06_15_2020 firmware installed. The instructions for both are in this thread.
Good luck!
