If you had any USB flash drive plugged in while booting, unplug it. If the bios Boot Order or similar settings are set to boot from a USB or sometimes a removable drive before any hard drive, flash drives are not bootable unless you prepare software on them to make them bootable, and in some cases when the bios is set to certain Boot Order settings the bios WILL NOT try to find another bootable device when it finds a USB flash drive is not bootable.

If your computer has a floppy drive, make sure there is no disk inserted in it while booting.

There must be an operating system installed on at least one partition on one hard drive in order for the bios to be able to find a bootable hard drive partition to boot from.

If all the hard drives have no data on them, or if any do but it has no operating installed on it, none of them will be found to have a bootable partition.

New hard drives have no data on them, so they can't be bootable. If you are trying to install Windows or the original brand name software installation on a new hard drive, or on one that doesn't have an operating system installed on it or has had it's data deleted, if you boot the computer from a Windows CD, or from the first disk in a Recovery disk set meant for your model, you will be able to install Windows or the brand name software installation that includes Windows on the drive, then the drive will be found to be bootable by the bios, one way or another.

When you have two (physical) hard drives or more, the default bios settings, or what they've been custom set to, may not find a bootable partition on the first hard drive the bios detects. The bios WILL NOT try to find a bootable partition on another drive when it doesn't find one on the first hard drive it detects. In that case, there is a list of hard drives in the bios Setup , often near where the Boot Order or similar settings are. The drive that has the bootable partition on it must be made the first one in the list, Save bios settings. Usually they're listed by their model number.
(A quirk is you can't use identical hard drive models with Windows - ones that are detected by the bios as the exact same model number.)
------------

Your Boot Order or similar settings in the bios Setup may be set wrong.

Your problem can be caused by....
- you don't have the network boot option in the correct place in the Boot Order or similar settings in the bios Setup

- you DO have that set correctly but
- the bios is not detecting your hard drive at all
- or - the bios is detecting the hard drive but it's not finding that it's bootable (has an operating system installed on it)
