Welcome to the forum @ombre703,
then you need to take a look at your software. Have you started looking at logfiles yet? After booting your system runs lightning fast, so just boot time is your problem?
The linked page below has information on how to use journalctl from the command line to find issues. Look if there is something during boot that doesn’t seem right. Alternatively, you can use the graphical Logs app, which is installed by default in Gnome.
There is also a tool to analyze your boot process, see the previous threads:
Really Long Boot Time - #3 by augenauf and Slow Boot Time on Fedora 31.
