New build desktop unable to boot from CD/DVD

[Valorus]

I have a Gigabyte series 5 desktop w/4 GB memory, 500GB HDD that is completely clean, Dban, etc. BIOS is set to run USB KB, BIOS reset, battery removed and
replaced. The problem I'm having is that when I try to boot to from a legal CD, the "boot from CD" option doesn't do anything. The no boot info box comes up
and I have to reboot with the same result. I've tried different usb ports, regular and USB keyboards and nothing seems to allow me to boot from the DVD.
It seems that the KB just doesn't work when Boot from CD/DVD: option comes up.
Of course I can't run any scanners, etc until an operating system is installed. I don't know if this is caused by malware, damage from malware, or a computer
problem.
Any ideas will be greatly appreciated.

You will need to set your BIOS so that the CDROM is the first boot drive.

Hi Dave. I've done that.
The problem is that the Boot option,"CD/DVD: doesn't respond to any input, keyboard (reg or USB).

Thanks for the prompt reply.

I'm going to move this thread to the Hardware forum. I'm sure someone there will help you.

If this keyboard is a USB Keyboard, it might not be mounted yet for the motherboard to see keystrokes. Have you tried a PS2 keyboard instead?  Using PS2 keyboard you should have immediate access to getting into the bios as well as chosing the F key command for boot selection if this motherboard has one such as F9 etc. Different motherboard bios's use different keys, but on my one system its F9

If the keyboard works fine and the optical drive is not booting. Move the SATA cable on the DVD ROM to SATA 0 or SATA 1 so it is recognized by system as a bootable device attached to this port. Seen before where a DVD ROM at say SATA 4 wont boot a bootable disc.

If the cable is already attached to SATA 0 or SATA 1, then I'd try a different SATA Cable and see if it begins to work. You can swap SATA cables between the HDD and the DVD ROM first to see if it fixes the issue, but be sure the Hard Drive to boot from is on SATA 0 or SATA 1 as well as the DVD ROM is in the other of the SATA 0 or SATA 1, with non-bootable drives using SATA 2, 3,4...

If it still doesnt work, then I'd try a different optical drive if a spare is available or exchange it for a new drive as for it may be defective.

When you set it to boot from CD 1st are you pressing F10 to "save changes and exit" ? ?

[Valorus]

Yes, but keep thinking.

I've even set all devices to boot from CD. Its normal now with CD as first boot device.
What happens is that we get all the way to: Verifing pool data, then a line comes up with "Boot from CD/DVD:" then nothing works, PS2 KB, USB KB,
and then a dialogue box says: Boot MGR Missing, Press Cont, Alt, Delete to restart, and around we go. All KB work on other computers and on the
splash screen here.

This a 3yr old Gigabyte 5 series that was originally set up as a gaming machine. The CDs are IDE, although I tried SATA drives earlier, the HDD is a SATA drive.

This computer quit a year ago with malware. I was busy and replaced this MB with a 77 and i7.  I have time now, and I'd like to repair this one.

I think the keyboard is somehow being disabled when given the option to Boot from CD. Just a theory.

Is your "legal CD" a DVD?
Is your drive a CD drive & not a DVD drive?

[Valorus]

It's a legal MS disk. I don't even get that far!
I have a bunch of CD and DVD drives and tried every combination I can think of, IDE,and SATA.
We've been assembling computers since the early 80s and I never seem to throw anything away.
MY biggest trouble is age. I've got CRS!

The first computer was a1979 Pixie, machine language and 1k memory, they're more complicated now.  I still have the Mag if anyone wants to see it.
Parts no longer available tho.

Please confirm your optical drive is a CD/DVD drive and not just a CD drive.

[Valorus]

It's a Phillips DVD player.

Although this MB was designed to boot from an IDE device, after putting a SATA DVD drive and changing ALL devices in bios to boot, the
Boot from CD/DVD: option brought up three boot options,  and allowed it to boot. I upgraded the bios and all is well.

Thanks for all your help and for making me begin to think again.

I use this computer for ham radio and need a USB-serial controller, (software, not an adapter) if anyone knows where to find one, Gigabyte doesn't have it anymore.
