did u install ur windows 10 in uefi ?

What are you trying to do actually? reset?

I  think not, because I just installed windows 10 normally, no idea about UEFI. Can I fix this without reinstalling windows?

hmm, im not sure either, no solutions found either on google.. u try one of these steps to access the advanced boot options?

What is uefi?

What is uefi?

My problem is I installed Windows 10 on the same partition settings as Windows 7 so the UEFI recovery partition was not installed properly. I referred to a guide basically telling me to delete all partitions on the drive, and create "new" partition settings during the installation process, now everything works.

next time to make life simpler don't use UEFI boot but regular BIOS boot

not you since youre already an expert on the above but for those that want to know the difference

I kept reading UEFI is better though, why is that?
Actually I have no idea about UEFI and BIOS when I first installed Win10, I just installed it like how I did for my Win7(format - install) and ended up with this problem.

better how better what?

how better? the trouble you went through better? wasted time and stressful better?

maybe some expert here can say how it is better but for me using windows since windows 3.1 I have no need for 'better' that I heard here and heard there - I find out and research for myself and understand matters and functions - I don't heard this or heard that to follow like a cow

but good luck anyway

Actually I was building a new PC with UEFI support so I wanted to make the most use out of it.

No troubles and stress at all, since I will only have to setup my Windows ONCE properly. I use UEFI because I know Win8/10 works best with it (in this case).

There are reasons they invented UEFI to replace BIOS in first place, you can google for the advantages if you're interested, otherwise, have fun with your ancient BIOS.

Advantages

The interface defined by the EFI specification includes data tables that contain platform information, and boot and runtime services that are available to the OS loader and OS. UEFI firmware provides several technical advantages over a traditional BIOS system:[12]
Ability to boot from large disks (over 2 TB) with a GUID Partition Table (GPT)[13][
CPU-independent architecture[
CPU-independent drivers[
Flexible pre-OS environment, including network capability
Modular design

of course youre right and searching you find a wiki that says
so you have a very large hard disk which is over 2TB to boot off huh? No wonder you need UEFI I see

wow you have a mobo and CPU that is very special hence you need the advantage of CPU independent arch
and your hardware drivers are unique and special too - awesome

you boot off the home network youre using your new custom built pc - amazing  

I salute your techno savvy advance-ness. Yes I'm sticking with good old BIOS boot bcos I stress easily

EFI can be faster, but that's not certain. The biggest speed difference is in hardware initialization early in the process. On my systems, this is a fraction of the total boot time, so a reduction in the hardware initialization time.

UEFI supports a feature called Secure Boot that's intended, as the name suggests, to improve security. It does this by requiring a digital "signature" of boot loaders, which in turn should require signing of kernels, and so on up the chain. This should make it harder for malware authors to insert their code into the pre-boot process, thus improving security.


Benefits of UEFI boot mode over Legacy BIOS boot mode include:
*Support for hard drive partitions larger than 2 Tbytes
*Support for more than four partitions on a drive
*Fast booting
*Efficient power and system management
*Robust reliability and fault management

LOL, why do you have to nitpick impractical features of UEFI to make your point?
Like I said, I am happy with my UEFI setup, no one is stopping you to enjoy your BIOS though.

nothing against UEFI or pro BIOS but wasn't this thread started bcos the root cause of the win10 non available Advance Startup option due to the use of UEFI being corrupted of sorts?
