Leaving the DVD/CD drive as first and the Hard drive as second is generally the best way to go. For most, you can disable the Network boot and if there is no floppy, disable it as well. Leaving the DVD/CD drive as first allows you to boot from a Windows disk, whenever you need to. Plus, if there is no bootable disk in the DVD/CD drive, it automatically goes to the hard drive anyway. This should make no difference in the time it takes to boot up.
If you leave the Hard drive as first, if it fails, then you won't be able to boot from a DVD/CD recovery disk or Windows disk unless you change the boot order again.
Also, many BIOS settings have an option to boot from USB, if you enable it. If USB boot is possible, many prefer booting from a USB/Flash drive first, then DVD/CD drive, the hard drive. You'll have to check your BIOS settings to see if USB boot is available.
All of this is your choice though. Do what you think is right.
Hope this helps.

Just updated my sisters computer, Compaq Presario CQ5320F, with the creators update. Per Grif Thomas instructions everything went very well. Just minor adjustments were necessary. Much easier then when I did a clean install from a CD ISO.
Anyway, noticed that boot seemed slow so I checked the bios. Was set as follows: 1-CD-Rom, 2-Hard Drive, 3-Floppy (has no floppy), 4-Network Boot. I changed to following: 1-Hard Drive, 2-Network Boot, 3-CD-Rom, 4-Floppy.
Wanting to know if this is correct. This was an Windows 7 OS, which I updated to Windows 10 last year, and now to the creators update. All windows updates done.
Thanks in advance
