Windows 10: how do I enable diagnostic boot?

Hi, My laptop is spending minutes stuck at the spinning circle thingie during boot, and I'm fairly certain there's some component waiting until timeout that's causing it. But since the only thing I see is the spinning circle thingie it's impossible to troubleshoot.

So how do I see what's going on during boot?

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.

Unable to login with Diagnostic Startup enabled

So I thought it would be harmless to start in diagnostic mode in order to troubleshoot a video driver and ran into this exact problem: login screen with no login text boxes or account picture. I tried every method listed here but I was unable to resolve
my issue. I even went so far as to attempt to enable the legacy boot option (good old F8), but could not seem to get that to work from the recovery console. Finally, I restarted the laptop and let it go to the blank login screen one last time and walked away.

An hour later I returned and there were the login picture and text boxes! It appears it was just a matter of patience while the computer ran whatever it needed in order to operate in diagnostic mode. Out of sheer morbid curiosity, I attempted to replicate
the process by re-enabling normal startup, restarting, and then enabling diagnostic startup again. Sure enough, after waiting about 15 minutes at a login screen with no login area, the picture and text boxes to log in finally appeared.

I'm not sure what processes were going on in the background which caused this painfully long delay, but I guess it's just a matter of patience. At least, that was the situation in my case. Keep in mind my laptop has dual display processors and an 8GB internal
SSD (which was used for fast boot in Windows 7, but does nothing in Windows 10), so those may have been what was causing the delay.
