Windows 10: window 10 clean install now boot options gone in BIOS

It all fired up and ran perfect. I was just poking around and noticed it took away all my boot options except windows boot manager.
I installed by entering bios and selecting removable drive Then from an iso file on a usb flash drive from Microsoft.. Now if I had to reinstall 10 with my flash drive I cant.
How can I add a boot option to the BIOS to the usb/flash?

Map to Windows 10 boot partition in BIOS

Hi,

I searched for this issue on Microsoft site and also on the internet but there was no posting on it. After the upgrade and restart yesterday, there is no boot option in the BIOS. Before this issue, I did a cleaned Windows 10 installed and noticed the BIOS
showed it is a legacy version without the Fast Boot option. Now it showed the Fast Boot option. Did the BIOS got upgraded?

Please let me know if it is possible to map to Windows 10 boot partition in BIOS and the steps for it.

Thank you for your help,

Mark N.

 

Windows 10 after hard disk failure

Hi Rowie, you have 2 options, you can upgrade from Windows 8 or clean install Windows 10. Neither Option will cost you anything . . .

Honestly clean installing Windows 10 would result in a more efficient system

Since you previously had Windows 10 installed and activated on that PC during the installation process skip the steps which ask for a product key and select the option 'I am Reinstalling Windows 10 on this PC', and activation will not be an issue, your PC will
have a digital entitlement stored on the Microsoft Activation Servers

If you want to upgrade then click 'Update Now' on that page

To clean install Windows 10, download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), you can create a bootable USB flash drive (min 8GB) using that
tool

Then, Boot your PC from the Installation Media you just created (change Boot Order in your BIOS)

If you have problems booting from a boot disc, you may have UEFI BIOS, go into your BIOS and make the following changes:

1. Insert the Bootable Media

2. Disable Secure Boot

3. Enable Legacy Boot

4. If Available enable CSM

5. If Required enable USB Boot

6. Move the device with the bootable disc to the top of the boot order

7. Save BIOS changes and restart your System

 

Do you have the Windows 10 installation USB flash drive plugged in? Many BIOS, especially if it is actually a UEFI firmware computer and not BIOS, will only show boot options that are actually available when the computer is powered on or restarted. It won't show options that are not physically present and capable of booting.

I also notice you marked this question as solved - did you already find this out?

 

It was an option before I did the install. Not after. It changed it some how. I'll try to plug in the flash drive ,thanks for the idea. No I have not solved it. My is 1st post didn't notice that I marked it as such.

 

Windows will not change the boot options in BIOS/UEFI. Adding a bootable OS will add to the menu, but Windows (nor any other OS) will remove what the BIOS / UEFI detects as bootable.

 

I figured it out!! It was the only program that I installed since the clean install, a damn Verizon phone repair program loaded and changed the boot menu. I noticed every time I boot up this screen would come on and asked if it could make changes to my computer. Once I unistalled it , VIOLA boot options back. Just to make sure, I did a clean install and removed all partitions to boot. Pardon the pun! Thanks for the help!
