Windows 10: Windows 10 new install uefi p1. 20

Hello. I search the internet and this forum but for me, there is no clean answer. So I ask boldly here and hope to get a straight answer.

My motherboard is Asrock h97 pro4. In uefi screen it states P1.20. I understand that when installing windows 10 i have 2 ways: bios and uefi. But uefi must be 2.0.

So, should i install with bios or with uefi?

Should I upgrade the uefi to 2.0?

What do I gain if instaling with uefi vs instaling with bios?

Thankyou!

:)

 

Can anyone to tell me what are meaning those P0, P1, UEFI?

In older PC and Notebooks I've never seen those terms: P0, P1, UEFI, and how can I see which of them should I use and how can I install my windows 10? What UEFI based means?

Thank you!

 

Which option to choose from P0, P1 and UEFI from the boot menu on Windows 10.

Original Title:

Before to boot in Windows, when I press ESC key, a menu is showing: P0, P1, and UEFI, which one should I chose, I read the user manual, and is still in Chinese for me, sorry for being a trouble maker, for me to install Windows in new days is more like rocket
since.

On my new Notebook Asus X555LB I had pre-installed Windows 10, I got an old virus from 90s, and now I'm trying to reinstall the OS, but it's hard to understand how. Which option I have to choose:

P0:

P1:

UEFI?

This is what bothers me, few mins ago I was asking how can I get a copy of Windows 10, now I'm asking what I must choose to make a safe and stable installation.

Thank you!

P.S.: Sorry if I'm rude and please excuse-me for my bad English.

 

Your BIOS is way too old. Upgrade to 2.0:
ASRock > H97 Pro4

My bold answer is to install using GPT partition scheme (UEFI).

• Support HD/SSD > 2TB. Technically unlimited but limit by Windows to 256TB.
• 128 primary partitions where MBR limited to 4 max.
• Faster Boot performance. This is because the device can use ACPI directly from UEFI
• Secure Boot (optional)
• Win 8/10 is geared to UEFI not MBR. Intel is only keeping MBR around for XP, otherwise it would be GONE

 

I never upgrade motherboard bios. Is it safe? Should i do it myself or should i go to an it specialist? Is waranty void if i upgrade the bios?

 

It's more or less bomb proof doing a upgrade to the BIOS and it won't effect warranty if it gives you the option save the old BIOS do so first

 

The link in my previous post shows instructions on exactly how to download and update the BIOS. See screenshot:

 

So, practicaly i am safe doing it. Ok. Still, just for my knowledge. What if the upgrade is not succesful. Can i broke my mb? What can happen at worse?

Sorry for insisting. I never done a bios upgrade and in my head this is a dangerous thing. I just want to clear my head with infos i can understand.

 

Just make sure that during update, you don't kick the power cord or turn off your PC.
On the new MB, they usually have dual BIOS that you can switch in case one is bricked or corrupted.

 

Mine sure don't have dual bios. Ok. Thanks for help

 

It has Crashless Bios though AFAIK ...... perhaps check out AsRock site if you are worried.

And

If you encounter problems while updating the new BIOS, DO NOT turn off your system since this corrupt BIOS might cause your system failed to boot up. Just repeat the process, and if the problem still persists, update the original BIOS file. If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need service.

 

I've flashed probably 20 bios upgrades over the years. Never had one go bad. Of course, unless it is a laptop or you have an uninterruptable power supply you can't do anything if the power goes out. If you are doing a laptop or do have a UPS, make sure the batteries are fully charged.
