Re: 4B not booting correctly

There are 2 HDMI ports to plug your monitor into.
Make sure you plug it into the socket next to the USB-C power socket, furthest from the 4 USB sockets & ethernet socket.

Re: RPI4 and Noobs

Explanation: noobs only works on hdmi-0.
Raspbian and other OSes will work on either hdmi-0 or hdmi1.
On startup, hdmi-0 has a red square in top left corner. Hdmi1 has a magenta square

You have the HDMI in the wrong socket. Change it to the other and it will work with everything.

Re: Raspbian virtual

1. Why does it need to be "virtual"? Why not just have 2 SD cards with Raspbian on each and swap them when needed? 2. RPi4 does not support booting from USB yet, but we hope it will in the near future. 3. Sakaki has a distro called 'nspawn64' that allows to run a separate 64-bit debian shell within ...

What colour is the top left corner of your rainbow square - Red or Magenta ? It's possible you have your HDMI lead plugged into the wrong socket. it must be the one next to the USB-C power socket (farthest from the 4 USB sockets). Or do you have a file called `autoboot.txt` on your NOOBS partition? ...

Re: Pi2+ First NOOBs install hit by power cut %-(

Ah yes, the type & size of SD cards is often overlooked when having such formatting/booting problems. It is important that your SD card reader (USB or otherwise) is suitable for the type of card you have. Many older PC/laptop built-in readers may not be adequate.

Sorry, after re-reading your posts, I had skipped over the fact that you had already wiped it: since I've been able to erase it with the Mac disk utility to give a single FAT32 MS Dos partition. So if you've re-copied the noobs files back to the card, then 'runinstaller' would already be there (it i...

Re: Pi2+ First NOOBs install hit by power cut %-(

On the noobs SD card that suffered the power cut, edit recovery.cmdline and add 'runinstaller' to that single line.

That should get NOOBS to repartition the SD card so you can start again.

If you get the 4 raspberries (and often some scrolling boot text) followed by a blank screen, then a commona cause is often that the new vc4_(f)kms drivers are not working well with your HDMI monitor. This is often due to different parsing of the EDID data from your monitor, or the use of a default ...
