[SOLVED] SSD Can't boot normally, what is UEFI?

[icel3oi]

Hello guys i'm a noob with technology, I installed Windows10 onto my SSD and had trouble booting it, after a long time of self troubleshooting i found out why:
I had to go into my BIOS and this category called "UEFI Hard Disk Drive BBS Priorities " to manually select my Boot Option #1 as my SSD. Apparently the normal booting sequence at the default/standard boot menu of BIOS doesn't work even if i select my SSD there.

Can someone explain to me why i need to go to this special UEFI menu to select my SSD(UEFI Hard Disk:Windows Boot Manager(P0: Samsung SSD 850 EVO 250GB) so it can boot instead of just selecting my SSD from the normal boot menu without the UEFI? And what is UEFI?

Thank you in advance :|

Unified Extensible Firmware Interface. It's the replacement for BIOS and what's been in use for the last ten years or so.

You go into the motherboard setup and boot from the Windows boot manager on your UEFI storage device because that's the way it's supposed to be done now, provided you are booting a properly configured UEFI system. Windows 7 - 10 will install in UEFI mode, if it's available and setup correctly.

So whenever i reformat or buy a new com, i need to manually go into bios to select UEFI mode? Motherboards don't automatically boot UEFI first?

You should normally be in UEFI mode, and the correct boot device should be automatic in most cases, but since when was basic configuration of BIOS or UEFI considered something one didn't do, when assembling their own PC or installing their own OS? Don't trust the settings for a motherboard to be correct out of the box.

You shouldn't have to change your boot device again unless it somehow gets changed without your consent. Pre-built computers will obviously come configured correctly. It's mostly a concern with do-it-yourself boxes.
