Computer can't get past BIOS, and doesn't have any boot options.

I don't know what version of ASUS I have, but it is relatively new, a few months ago my computer started booting in BIOS, but I thought nothing of it as I could still boot just fine, just had to press escape to boot, but a few weeks ago my computer wouldn't boot when I pressed escape, there is also no installed storage drive, as well as no boot options in the boot menu, and the boot priority list is blank. I tried to find fixes myself, but didn't find any because I don't know what version my ASUS is, if you could please help me that would be great.

I have Asus M515D, straight from the shop.

I have no CSM option, disabled both Fast Boot and Secure Boot Control but no CSM. Also under Boot menu there is nothing listed. Can’t do anything. Is there a faulty disk? Disk is nVme.

Have you tried booting from a bootable USB flashdrive just to prove that boot manager is working?

If it is straight from the shop is it new or under warranty etc or has it just been repaired? In either case take it back.

I have never personally seen a bios not show all the different screens completely except for once when the laptop was actually hanging up when loading all of the screens. I don’t know how long you waited every time you booted this up but I just thought this could be a possibility. Just throwing that out there.

Solved it with an old USB external CD/DVD read/writer...

From what you have said and assuming that the hard drive is still in the computer and there have been no attempts to open the computer or remove the drive it could be a hard drive failure. That would then not report to a system post the hard drive as available.

Is the laptop still able to get to the BIOS ? if I have understood you right I would personally use a bootable USB drive and set the BIOS to allow to boot from USB. if that will boot for you then it could well be a simple case of a replacement hard drive

You can download the tools to either make a USB boot drive drive from a USB or download the image of one and use that to create it but either way its very simple and lots of tutorials online you can find using a search engine

Ok, so if I'm understanding you, I should essentially load windows onto a flash drive and boot from that? And the only possible problem is a bad hard drive? Also, to answer your question, yes it does boot to BIOS.

さんによる

Any bootable USB does not need to be windows just a bootable USB for anything if it loads without an issue it would point to a failed internal hard drive so then replace the hard drive and reinstall windows and problem sorted

Hi @ Gustavo,

Knowing the full model number would be helpful. Is there nothing written in BIOS or on the case to tell what the model is? Also what OS was installed and working before?

It may be that you cannot boot using a USB if the boot options are not showing. It may not look at the USB to boot from if the boot order is missing The HDD may have been the only enabled option for example

さんによる

But in a situation whereby the hard drive is completely removed and the system still boot to bios. All of the above solution have been tried, thanks for all your advice, but the system still boot to bios. Whàt next?

  1. In Boot Menu -> Change FastStart to [Disable]
  2. In Security Menu -> Change Secure Boot to [Disable]
  3. Then 'Save Configuration & Exit', when the BIOS screen appears again
  4. Go to the Boot Menu again -> Change Launch CSM to [Enable]

I found that some PCs will not boot off a USB drive. some examples, most windows XP machines, older macs, I'd say use a windows installation disk as in BIOS the order is always defaulted to Cd drive first, HDD second. makes it so non technical users dont have to mess with the BIOS and just pop in the windows CD.

Change it to Legacy boot and move the internal drive up in the Bio settings.

So I’m having an issue that seems similar but not. Loaded windows 11, now it starts at the asus logo screen but immediately switches to the Aptio setup utility. I’m concerned bc under the boot tab it literally says:

Fast Boot [Enabled]

Boot Option Priorities

Delete Boot option

And nothing else. Please tell me there is a way to fix this. It looks like all the boot options are just gone.

さんによる

@T B Disable fast boot

さんによる

Did that but doesn't work

さんによる

@T B did it work?

@Ryan Jacob Alright try Boot Option Priorities and tell me what it says.

I have an asus rog strix scar. No devices in the bootable drives menu, but it does recognize my 1tb ssd. I tried using a usb windows 11 bootable drive but it leads me to error screens. Never seen a device that won't let me use a bootable usb drive. Any ideas why it doesn't want to boot up and install windows on my main ssd?
