Computer tries to boot from CD-Rom before hard drive. A problem?

I upgraded from Windows 7 to Windows 10, and now, whenever I restart my computer, it briefly gives a "Boot from CD-Rom" (or some such words to that effect) message, then gives a second message saying that it is now attempting to boot from the hard drive. This whole process only lasts a few seconds, then Windows boots up. Is this a problem?

Do you have a DVD/CD inserted in the drive?

You can also press the Win key + R at the same time to open the run dialog. Run MSCONFIG. Click the boot menu. Do you have only one entry in the list there?

This is what I would call the normal sequence. One should always set the CD drive as Nr. 1 in the boot sequence so that one can quickly load a live CDVD in case of trouble.

No.

Yes. Windows 10 is the only item in the list.

I see. I don't recall this happening with Windows 7 (or Vista, for that matter), though.

This actually shouldn't be happening if Windows 10 fast startup is turned on because the computer isn't supposed to power down all the way to the bios boot sequence.

How can I tell whether Windows 10 fast startup is turned on?

I found two pertinent details.

Firstly:

The fast startup setting doesn’t apply to Restart. You need to shut down and then start your PC again for fast startup to take effect.

I was restarting the computer when the matter referenced in the thread title happened.

Secondly:

If you disable hibernate, then it will also disable fast startup.

I checked my settings, and found that while "Turn on fast startup" is checked, "Hibernate" is unchecked.

Should I enable hibernation (in order to enable fast startup). Does fast startup provide all that much of an advantage?

This has really nothing to do with Windows. It is a BIOS setting.

That is completely true. With Windows 10 Fast Startup enabled, if the user just clicks Shutdown...then the computer should not shut all the way down for that bios setting to take effect. When powered back on the computer should not be checking for a CDROM to boot from first, if the fast startup is working properly. Clicking Restart instead of Shutdown will cause the computer to restart all the way back from the initial bios loading with the CDROM first option. Also holding down shift key when clicking Shutdown will bypass the Windows 10 fast startup and the subsequent power on will be all the way from the beginning, with bios checking for a CDROM to boot from.

All this is only IF the boot from CDROM is marked as a boot device before the HDD is in the bios boot order.
