Windows 10: BIOS keeps booting into wrong drive even after changing boot order.

Hello, Recently out of nowhere my system boots into my HDD and not to my boot drive NVME drive. I don't have Windows installed on the HDD only on my NVME. Every time i turn my pc on it goes into Diagnosing problem with start up and leads me to the recovery menu. I have to go into UEFI BIOS from there and then change boot order to my NVME drive and reboot into Windows. I noticed it says "Windows Boot Loader" on both of the drives listed in BIOS boot selector. I only have some programs installed on the HDD and only use NVME for boot. I haven't installed any new programs or anything it just hap

:)

 

Boot order in BIOS is changed to a USB but restarts keep going to Windows

So here's a riddle.

-I have a PC set to boot off of a USB regularly instead of Windows to access a Linux work environment.

-The drive is set up to boot with UEFI, created using unetbootin

-BIOS is modified to have USB hard drive/USB flash drive at the top of the UEFI boot order list

-Secure boot is disabled

-The system boots to the drive without issue after changing these settings

-The system boots to the drive after rebooting from that environment without issue

-I shutdown the PC and pull the drive out, then boot up when I want to use Windows

-After inserting the drive, I reboot from Windows, the system keeps booting back into Windows

-I assume the drive has a bad connection, but I'm able to see the drive is recognized in Windows

-I assume the system is just not entering the right power state in this process, so I hold down the power button and do a hard reset. The system continues booting into Windows.

-I assume Windows is actively changing the boot order or re-enabling secure boot(which I can probably prevent with a BIOS password)

OR

-I assume the BIOS is forgetting the drive and reverting the boot order

OR

-I assume the CMOS battery is defective and the BIOS is reverting to defaults

BUT

-When I go back into the BIOS settings, USB hard drive/USB flash drive is at the top of the UEFI boot order list and secure boot is still disabled.

-I ignore changes and exit the BIOS, suspecting an issue with the drive itself.

-Every time I exit the BIOS like this, the system boots to the drive without issue.

-I still strongly suspect this is something with the power state not going down to the proper level, which is why I'm reaching out here rather than with the BIOS manufacturer.

Appreciate any thoughts.

 

Can't Change Boot Order

Cloned original C:\ drive to an SSD drive then followed the windows procedure to get to BIOS to change the boot order:

• Settings
• Update and Security
• Recovery - Restart Now
• Troubleshoot
• Advanced Options
• UEFI Firmware Settings
• Restart

The last restart does not take me to BIOS. I just get a blank screen. Esc key gets me back to Windows, but I don't want to format the original C:\ drive for other use until I am able to change the boot order. How do I do that?

 

Bios will not save boot order

Hi Guys,

Thanks for the input. A quick update, my computer is booting fine. It used to give me the error message associated with the boot manager not being detected.

Oddly, here are the steps that worked...

If I were to go into bios, I won't see my boot drive. If I power off, disconnect and reconnect the SATA cable, and power on, its recognized (quick note, I'm on Intel, and I've connected boot drive to SATA port 1). Then I would boot directly off the drive through bios. Any subsequent boots after that and it loads windows.

Now it seems it doesn't matter. I've been running SimCity all day so far and my PC is mostly stable, except for stupid ATI drivers *Frown I'll be starting a thread there next *Smile

I'll reset CMOS if this keeps happening.
