I have a pi (Obviously), but it won't boot fully. I have the SD card that came with it (I payed extra for the pre-formatted one) and it boots just fine, shows the normal console, and I don't see any errors (one command failed to execute according to it, but it said it ignored it and it didn't look important). Once it's done booting, it shows a black screen. No mouse cursor, no way to input anything. I was wondering what I could do? I am running raspbian 11 or 13 (don't remember which). My friend brought over RISC OS and it didn't boot either, it hung at the console. Any help is appreciated!!! (I need it for a project if you may be able to help but it's not the end of the world.)
I would check the power supply (or borrow from your friend). Many power supplies do not provide enough juice even when they say they would.
If you have the model with Ethernet, you may want to check if it assigned the IP and try to ssh from there. If you could login, that means your monitor is not accepting the signal after the boot (you can configure various HDMI settings using config.txt file).
