Question PC boot into BIOS everytime I start it

[Clannadzx]

Hi,
My mb is ASUS ROG MAXIMUS XII HERO. I have two m.2 SSD. I use Samsung 2TB as Windows drive and other Sabrent 4TB as a storage drive. After I installed Win10 on Samsung and start my PC, the system will automatically enter into BIOS mode, not Win10. How should I fix this? Thanks, guys!

probably the watch battery that holds the bios boot sequence needs replacing.

Thank you for your reply. But this is a new motherboard, It's that normal this could happen on a new motherboard?
Thanks

What bios is it in uefi or legacy ? What are the partitions gpt or mbr ?

 

[RARRAF]

ohh well no not generally
are you on the latest bios ??

What bios is it in uefi or legacy ? What are the partitions gpt or mbr ?

My settings are:

CSM:
Launch CSM: Enabled
Boot Device: Control UEFI and Legacy OPROM
Boot from network devices: Legacy only
Boot from storage devices: UEFI only
Boot from PCI-E/PCI expansion devices: Legacy only

Secure Boot:
OS Type: Windows UEFI mode(or other OS)

Boot Configuration:
Fast Boot: Disabled
(two mush options in here.)

Boot option Priorities:
Boot Option #1: Windows Boot Manager---M.2_1: Samsung SSD 970 2TB (other options: M.2_1 Samsung SSD 970 2TB / Disabled)
Boot Option #2: Disabled(other options: Windows Boot Manager M.2_1: Samsung SSD 970 2TB / M.2_1 Samsung SSD 970 2TB )

Boot Override
Windows Boot Manage ---M.2_1: Samsung SSD 970 2TB

As for partitions gpt or mbr:

At the first beginning, I ran disk management. PC pop up ask me and I do not know which one to choose so I selected MBR. Later I realized that MBR separates my another 4TB SSD into 2.6 and 1.4 TB. So, I right-click that 4TB to change it to GPT. Then it shows a full 4TB ssd. So, I think I fix this problem. And, I just checked 2TB SSD, it shows GPT. But, separated into three parts: 100MB HEALTHY EFI SYSTEM PARTITION//// C: ///// HEALTHY RECOVERY PARTITION.

That's all the info about my bios settings.
Hope you can help me.

Thank you appreciated!

Thanks for the reply.
Yes. I think so. I double-checked that my BIOS on my ASUS motherboard is the latest.

When you see bios splash screen can you enter boot selection by pressing F11, or whatever it is on your mobo ?

No. After I hit the start button, the screen shows an Asus logo, and below that: Press F2 or DEL to BIOS or UEFI. I do not need to do anything cuz every time after this the system will enter into ASUS BIOS automatically. And, every time I have to go to quit without saving. If luckily, I can direct to win10. If not, I have to do this by several times maybe change some other settings to win10. I literally do not know which parts are wrong.

Thank you.

so why are you quitting without saving if you save it you will not have to go through the same last post on subject.

Hi, I realized that If I did nothing but select discard&exit. The system will boot into win10. But, this means every time the pc will boot into BIOS first and win10. Must be something wrong to make it let this. If I tried several settings but they all fail. And, it will increase the boot times that my system into win10 which is very upsetting. So, I want to figure out which parts and boot win10 directly.
Thank you

Normally a bios goes through a list of devices that could be bootable, if your nvme is last on the list it's always going to take a long time, maybe that's why it enters windows randomly.
If you enter bios and put the nvme first on the boot device list it will try to boot from it first.

Yeah I had the same thing at first when I switched to uefi, switched to legacy and boots fine

Your system is installed in UEFI. Legacy boot mode is not necessary.

Set Launch CSM to disabled.
Set Boot Device Control to UEFI only.
Set Boot from PCI-E/PCI expansion devices to UEFI only.

Save settings and reboot.

These two are under CSM. If I disabled it, there will be no options for these two settings.
Thank you!
