Failing to install Windows 10 in UEFI boot mode

Hi

I’ve been reading articles in this community and others the last couple of days and I’m getting more and more confused.

I have made my first build with the following equipment:

Asus Prime Z370-P (Bios version 1002x64, firmware 11.8.50.3470)

Intel Core i5 8400 2,8GHz

Samsung 860 EVO Series MZ-76E250B 250GB

and other..

I purchased a Windows 10 Home Eng Retail licence on USB directly from Microsoft.

When installing Win 10 it always ends up being installed in Legacy BIOS mode.

First time, I only followed the instructions on screed and had a successful installation, but in Legacy Bios mode.

The second time I made the following change the UEFI:

Boot\Secure boot\OS type = Windows UEFI mode

Installation was still being made in Legacy Bios mode.

Third time

Boot\Secure boot\OS type = Windows UEFI mode

When Win 10 installation started I entered the cmd prompt and made the following commands in order to change to gpt

Diskpart

List disk

Select disk 0

convert gpt

Exit

I then continued with Windows installation which still ended up in Legacy Bios mode.

I’m getting crazy and I don’t know what I’m going to do : (

What do I need to change in the UEFI?

What do I need to do to prepare the disk for UEFI mode?

Is my purchased Windows 10 USB key prepared for UEFI mode?

Can someone describe, step by step what I need to do?

 

UEFI install Windows 10 was A LOT OF work!

After getting my new HDD I decide to finally fresh install Windows 10. My old installation was having all kinds of problems causing BSOD every now and then. I have flashed my FuryX to UEFI vBIOS so I assumed this time UEFI installation should be a walk in the park. Well, turns out it was not.

First off, there are multiple booting options in the Sabertooth X99 BIOS I have to choose correctly to get through UEFI installation crash free. For example, I need to choose UEFI in Secure Boot for the installation DVD to even be recognized as UEFI installation media. However, I also have to enable CSM in legacy mode to make sure no plugged in device will crash the installation in process. I had four crashed during installation for not choosing the correct CSM settings. Another thing is after the whole installation I have to make sure to disable CSM to enjoy the speed of secure boot. The entire installation took me a good 5 hrs to figure out all the details.

The good thing is a clean UEFI installation of Threshold 2 proves to be very stable. No more random crashes nor tons of errors in event log. It was a lot of work but still worth it. I just wish Microsoft will make the installation in UEFI a lot easier.

 

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated
