I know that I'm replying to a 6 month old post but I found a solution to this problem that others may
I have a Samsung NP355E5C (aka '355E') laptop and could find no way to boot with anything but the
internal hard drive.
I was getting rid of Win 8 and installing Win 7 from a DVD, which wasn't happening because you can't
boot from a CD/DVD.
Ok here's the steps I took: (a couple may not have anything to do with anything but a couple are very
important because you can boot with USB or CD/DVD afterward)
Boot computer (turn it on, for those technologically challenged) :)
Hold or continually tap F2 key to enter BIOS Setup. If you see the Win 7 "Starting Windows" or the Win 8
"spinning circle" you waited too long and will have to try again.
Once inside Setup, under the 'Boot' tab, I set 'Secure Boot' to 'Disabled'.
This will cause an 'OS Selection Mode' to appear beneath 'Secure Boot' that wasn't previously visible.
Change the 'OS Selection Mode' from 'UEFI OS' to 'UEFI and Legacy OS'.
Now go back up to the top listing on this page, 'Boot Device Priority' (still under the 'Boot' tab), which
previously only showed that the internal hard drive was the only bootable device.
Highlight it and press Enter. Note that it will probably still show only the internal hard drive listed.
Don't worry as this only requires an 'Exit Saving Changes' or use the F10 key shortcut for this same action.
Now, during the restart, press F2 again and once again enter the BIOS Setup.
If you go to the 'Boot Device Priority' under the 'Boot' tab, you'll now be able move up or down the devices
that you want to boot first.
(Despite advising to look in here again, when I simply changed the 'OS Selection Mode' to
'UEFI and Legacy OS', it booted from my DVD on the next restart i.e. I didn't have to go in a second time
and set the boot order up or down as desired. It defaulted to my DVD boot.
Under the 'Exit' tab, it will say 'Boot Override' along with the name of your internal hard drive.
So, now it will boot from a USB device or CD/DVD drive.
