Welcome to Raspberry Pi Stack Exchange
Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for the Raspberry Pi. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to specific questions.
We're a little bit different from other sites. Here's how:
Ask questions, get answers, no distractions
This site is all about getting answers. It's not a discussion forum. There's no chit-chat.
Just questions...
...and answers.
Good answers are voted up and rise to the top.
The best answers show up first so that they are always easy to find.
The person who asked can mark one answer as "accepted".
Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.
RPI4 won't boot with powered USB hub
I have an RPI4 running a Plex server, Pihole, etc etc.
Power kept dropping while running certain tasks involving the attached HDD, so I started using a powered USB3 hub - problem solved.
But now the Pi won't boot with the powered USB hub attached. I have to unplug it, wait for boot, then plug it back in.
What am I missing?

You have to make sure that you are getting consistent 5V from the USB hub, and at the very least 1 Amp in current... most usb hubs will only regulate to 500 mA which sounds like what you were getting due to the power drops. Did you see a lightning bolt on the screen when working on the Pi either on commandline mode or Desktop? If you did, you got your answer :)

I found the exact same issue in a Reddit post and the solution seems to be a frustrating one - find a more expensive powered USB hub. Oh well.

Get answers to practical, detailed questions
Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.
Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.
Questions that need improvement may be closed until someone fixes them.
Tags make it easy to find interesting questions
All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.
Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.
