Can't Boot From DVD Drive; DVD Drive Missing From BIOS!?

Put together another computer running Windows 10 64 bit, version 22H2.

Motherboard is a Gigabyte B760M Gaming X AX version 1.0 with latest BIOS (updated by store technician).

Computer has two SSD's, one HDD, and a DVD writer.

By default computer boots from one of the SSD's which has Windows 10 installed as the operating system.

Wanting to prioritize boot order so that boot is from the DVD writer first, and then boot from the SSD if no DVD/CD present in the DVD writer.

Initially, when setting up the boot order in BIOS, there were two boot selections available - SSD and DVD writer. I set the DVD writer as the first boot option (with the SSD as the second boot option). The computer did successfully boot using the DVD writer with a DVD inserted.

However, later on after updating Windows 10 using automatic updates, I then noticed the option to boot with the DVD writer has now disappeared from the BIOS menu!!?? So the ONLY boot option available now in BIOS is just from the OS SSD only!?

The DVD writer is detected by the operating system (Windows 10), and via windows/file explorer, DVD's inserted within the DVD writer are detected and can be played. So the DVD writer appears to be fully functional when running under Windows 10. But for some reason is no longer detected in BIOS!?

What is wrong here? Why is the DVD writer no longer detectable by BIOS? I need the writer to be detected and to be set as the first boot device under BIOS.

Thanks for the quick response!

Yes, I tried the F12 key on boot, but the only option there is for the operating system SSD. There is no option for the DVD writer.

In that case... you should probably check the cables running to the optical drive.
It could be a loose or bad SATA or power cable.

The only other thing I can think of is to make sure you haven't connected the optical drive SATA cable into a motherboard SATA connector that is disabled.



In your BIOS.... on the Settings tab... find SATA Configuration and make sure all your SATA controllers are "enabled".

I don't think that there is a problem with the SATA data cable. As mentioned in my first post, the DVD writer is seen under Windows 10 and I can run/play DVD's in the drive. The drive is detected under SATA configuration within BIOS, but the drive still doesn't appear as a selectable boot option under the Boot setting.

I noticed that there is a button labelled "Disabled" under the Boot settings option when selecting the boot device. Maybe the DVD writer boot option when selected (this was when the DVD writer boot option was available initially before it subsequently "disappeared" from the boot device list), was "Disabled" when the Disabled button was somehow pressed accidentally?

If so, how to restore the disabled DVD writer boot device option? I can't seem to find anything (so far) within BIOS that allows one to add or restore a boot device!?

Did you try with a bootable disc in the dvd drive?

Does the drive show under Computer?
Is the boot disk in the drive when trying to boot from the DVD drive?

Try the suggestions here: https://support.microsoft.com/en-us/...er-programsTry this too:Right click Start>Run & type regedit & click enter, find HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}Click on this folder - {4D36E965-E325-11CE-BFC1-08002BE10318} & under the right-hand pane right click on UpperFilters & choose delete. If the filter is named UpperFilters.bak then please do not delete this.If there is no UpperFilters entry then proceed to delete the LowerFilters entry.Close regedit & reboot your PC.If this doesn’t work try this fix by Kapil Arya:Try these steps: 1. Open the Command Prompt with administrative privileges. 2. Type the following command and hit Enter key: reg.exe add “HKLM\System\CurrentControlSet\Services\atapi\Controller0” /f /v EnumDevice1 /t REG_DWORD /d 0x00000001 3. Exit the Command Prompt and reboot. Insert a disk to test and the optical or DVD drive should be visible now.

As mentioned in my first post, the DVD writer is seen by Windows 10, and I can run/play disks within the drive.

The Microsoft help relates to drive not seen by the operating system. But as my drive is seen and runs under my operating system, that help page is not applicable.

I had a look under regedit for the applicable entries, but couldn't find any UpperFilters nor LowerFilters entries.

The DVD writer is seen by the operating system, so the mentioned fixes do not appear to be applicable.

The only issue is that the DVD writer no longer appears as a boot device option within BIOS, despite being detected and connected to a SATA port as shown under BIOS SATA configuration.

You need to look in the Bios not just the Boot menu.
The Bios is where you decide what to show in the Boot menu.

On several computers, I've had a Bios that not only set my boot order but also allowed me to remove entries from the list so that only options I might routinely want to choose got listed in the Boot menu.
- It also allowed me to re-add options to the Boot menu.
- I used to remove my optical drive from that list because it used to take such a long time to check it to see if there was a bootable disk in it every time I booted.
- I only re-added it to the Boot menu on those rare occasions when I wanted to boot from a CD/DVD.


Because of what I had set up in the Bios, if I used F12 to bring up the Boot menu only the HDD & the USB would be listed.

Here's another example -

For this computer, I only allowed routine booting from its HDD.
I could always return to the Bios to add other options if I ever needed to.


Perhaps you have set up a similar capability in your Bios.


Best of luck,
Denis

Yes, I have looked just about everywhere within BIOS to see if there is some means of adding or restoring a boot device (to the boot menu). Unfortunately there doesn't seem to be a way of adding nor restoring boot devices (to the boot menu) within my BIOS!!??

As mentioned in a recent reply, the DVD writer boot option may have been accidentally disabled or deleted somehow within BIOS boot settings when the drive was selected/highlighted and the "Disabled" button was somehow accidentally pressed?? The Disabled button appears at the bottom of the list of bootable devices.

If this was the case, then how to restore the disabled drive?

Was this post about the Boot menu or the Bios?

?

This post relates to the disappearance of the DVD writer as a bootable device under Boot Settings within BIOS.

The DVD writer was initially listed as a bootable device and the system did actually boot from a bootable disk within the DVD writer. However, and maybe it is coincidental, after updating Windows 10 for awhile, I noticed that the DVD writer had subsequently disappeared from the list of bootable devices with BIOS Boot Settings.

Maybe the Windows updates caused the DVD writer to disappear from the list of bootable devices under BIOS Boot Settings somehow? Or, I might have somehow accidentally "Disabled" the DVD writer within BIOS Boot Settings by accidentally pressing the Disabled button at the bottom of the list of bootable devices within the Boot Settings menu?

Yes, the system no longer boots with a bootable disk within the DVD writer.

But the DVD writer is recognized by Windows 10 and I can run and play disks within the DVD writer as usual.
