The 'Boot from USB' option has disappeared in the BIOS

[adamamerica]

Hi,
I don't know what has happened but the option to 'boot from the USB device' has disappeared in the Boot Menu in the BIOS:

Boot Manager
Boot Mode UEFI
USB Boot Enabled
PXE Boot to LAN Enabled

EFI
Windows Boot Manager
ST ..... SSHD-8GB
ST ..... SSHD-8GB
ST ..... SSHD-8GB
EFI Network for IPv4 ....
EFI Network for IPv6 ...

Clearly, there are three IDENTICAL items referring to booting from the HD (Hard Drive). Obviously, originally there were two different options present (something like that):
DVD/CD .... <----- to boot from a CD/DVD device
and
USB ....... <---- to boot from a USB device

I really don't know what has happened, but I think that the culprit is having a dual-boot system:
Windows 8.1 and Windows 10 on my Lenovo IdeaPad Z710 laptop. When I created that dual boot system, a year ago, I needed to run two (free well-known programs) to correct the boot-manager-database. Perhaps those two programs did MODIFY the Boot manager menu?!


As I've read updating the BIOS is risky and not recommended.

Final question:
Will restoring my laptop's pre-installed Windows 8.1 system to the FACTORY settings also restore the BIOS to its original state?

Thanx

No, you are factory resetting your OS which is on your storage device.
Your BIOS, which is stored in ROM, is unaffected.

Thank you.

I wonder what should I do?
As I have read flashing BIOS is not easy and quite risky?

Any suggestions?

Flashing the BIOS isn't necessarily hard, but if done wrong it will "brick" your motherboard, rendering it useless.

Try using different USB's, or a DVD.
