Question How can I find what error messages popped up during boot?

I'm new to configurations and installations.

I am using the latest Arch Linux x86_x64 installation.

I have successfully completed my installation, but some messages popup during boot in the top left of the screen. After that, it flips to a new screen and then the login.

How can I find out what exactly those error messages were so I can start eliminating them?

btw - side note: I have an installation of the exact same os on another computer and there are no messages and errors. So it's definitely because the hardware is different.

This is my start for learning to troubleshoot a Linux installation, so please be gentle if you can help!

@krlb you can view errors that showed up at boot time using the dmesg command, this will basically show you how the devices (hardware) were turned on or if any failed. Generally you should be able to see useful information from the output of the command.
you can also open the /var/log/messages file but I strongly suggest you go with dmesg tool. Just open your terminal and type the output.

hope this helps

Is it ok to post the entire output from dmesg here? or should I use hastebin. I would like to know if someone can look at it and tell me how to interpret it. It's not clear to me what might be an error. On the screen I mentioned that jumps too quickly there were only 3 or 4 errors. I don't know what to compare from the dmesg output?

What do you guys suggest I do. I'm available to post right now.

These two statements exclude each other, I'd say. Archlinux is not for beginners. I did the same thing and eventually had to pay the price for a badly maintained system.

Having said that, Archlinux is known for its excellent wiki and helpful community. Check there as well.
