Boot your Raspberry Pi from the USB mass storage device.
After five to ten seconds, the Raspberry Pi should begin booting and show the rainbow splash screen on an attached display.
Note that if the USB boot bit is set, you do not need to insert an SD card into the Raspberry Pi for USB boot to work.
It would be nice if it was really that simple, but for a lot of people it's not. The Raspberry Pi boot-loader is not compatible with all USB mass storage devices, resulting in problems for some people. Symptoms are either not booting at all, or cold boot works but reboot does not. And people who want to boot from a hard drive can have additional problems due to their power consumption and long spin-up times.
There used to be a USB 3.0 to SATA III adapter cable from a company called ELUTENG that was the Holy Grail of USB booting for the Pi. I tested it on more than a dozen SSD and HDD models from 6 different manufacturers and it worked on every drive I tried (powered only by the Pi's USB port). But alas, that adapter has been replaced by a new model that does not work as well. However, there appears to be an identical product available from TNP on Amazon USA
, but not Amazon UK. I tested the TNP with SSD models from Silicon Power and Crucial, and HDD models from Toshiba and Western Digital, and it worked with all of them.
Oh, and the USB boot OTP bit is already set from the factory on the newer 3B+ and 3A+ models.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
