Windows 10: Windows 10 Boot Manager not Displaying During Boot

Hi Microsoft Community,


I have a pc with Windows 10. Recently I noticed that I was not able to see the boot manager during boot, so the screen has no signal until I see the Windows login screen.


I tried to search online and followed the options to set "displaybootmenu" to yes and "timeout" to 10. But still not managed to get the boot manager to display.


So I decided to reset my pc, and again, the pc just stuck at black screen or no input signal when I reset my pc. I tried to boot into "Safe Mode", however, it is still not showing the boot manager and just boot into normal windows.


I have been stuck in this for the whole day, may I get some advices from people with similar problems?

Thanks,

:)

 

windows 10 slow boot

I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.
