After installation, lemon wheel just spun. Did i do something wrong?

Hi. After installation finishes, the lemony linux icon or something that looks like it, spins and says to eject the disc and then hit Enter. after i do that, the text instruction disappears but the wheel keeps turning. left for 5-10 minutes then restarted the system and it boots and works fine but i'm worried i did something wrong or that something went wrong.

It looks like it failed to restart and you had to give it a kick in the butt. This is certainly annoying but you did nothing wrong and shouldn't worry about it

If there is an issue where you encounter the same issue there is a sequence of keys that like control+alt+delete work at a very low level to force the system to do a safe reboot

https://en.wikipedia.org/wiki/Magic_SysRq_key

basically hold down alt+sysreq followed by r e i s u b you should be able to let go of sysreq as long as you hold down alt

so basically hold down alt and press sysreq r e i s u b

in sequence not at once

thanks

This is less important in the case you encountered because everything was already unmounted presumably however in the case where your installed system is hung up this can help ensure you don't lose work or mess up your files

oh, i see, in different situations of a freeze or hangup outside that post install phase. good to know

on mint cinnamon, you can always use ctrl-alt-backspace to quickly exit the desktop, killing any delinquent thing immediately.
