I have a Raspberry Pi 3 Model B+ with a 32 GB Memory Card. I had to format it to FAT32 using the guiformat.exe shown on raspberrypi.org. I then extracted the NOOBS zipped folder into the SD card. I plugged my Raspberry Pi into a screen and turned it on, only to see a pop-up saying "Cannot find the drive with NOOBS files". Does anyone know what happened?
To quote from a related issue:
This error can happen if your SD card has been formatted without a partition table.
As stated in another related issue:
Without an MBR partition, you can only have a single 'partition' on the card, which means NOOBS wouldn't be able to create any new partitions to install any OSes onto
So it looks like the card has not been properly formatted.
