The only way I know to slow it down a bit is to use a serial console to another system. Then you use that other system to record what is going on.
It is overly awkward, but Linux is fast - the messages are not intended for real time analysis, but most are recorded for post processing (dmesg and the /var/log/message file).
Normally you'd check the log files as indicated above, see also boot.log.
However, you can hit the 'i' key early on in the boot sequence and it'll go interactive for at least part of the startup.
It'd be pretty tedious though

The only thing about dmesg is that it is a long list & most newbies don't know that when you're in terminal you have to go to Edit>>Profile>>Preference>>Scrolling & select "Unlimited Scrolling" to view everything in terminal.
try either of the following commands
$ dmesg | less
OR
cat /var/log/boot.log | less
you can execute the above commands as normal user
OR
you can check the /var/log/messages file. you need to be root to be able to access this file.
