|The bios not detecting a BOOTABLE hard drive is a separate thing from the bios not detecting a hard drive !|
The motherboard's bios DOES NOT require that drivers be installed in order for it to detect a SATA hard drive !
If the bios is NOT detecting the SATA hard drive at all, of course the bios can't find it and it can't find a bootable hard drive !
Go into the bios Setup. Is the SATA hard drive being detected there ?
If the bios is NOT detecting it there....
- Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)
The same thing applies for the SATA power connection.
- the hard drive must be spinning.
Some power supplys have more than one +12 v output section.
In rare cases we HAVE heard of, one of those +12 v sections has failed. If the hard drive is getting no +12v power, it won't spin, and the bios cannot detect it.
- The bios must be set so that all drive connections are set to Auto detect drives by the Auto (or LBA for hard drives) method, or similar.
It's set that way by default.
If it's possible someone has set bios settings wrong, load bios defaults, save bios settings, then look in the bios again to see if the SATA drive is being detected
If the bios IS detecting the SATA hard drive....
The bios not detecting a BOOTABLE hard drive is a separate thing from the bios not detecting a hard drive !
The bios checks the FIRST hard it detects to see if it is bootable (has a bootable partition).
The hard drive will NOT be found to be bootable
- if it has no operating system installed on it - e.g. a new hard drive has no data on it - a hard drive that has had it's operating system deleted will not be bootable
- if it does have an operating system installed on it but the data on it is corrupted enough such that it's not found to be bootable.
- if you have the Boot Order or similar set so CD drive or similar is before hard drive or similar, if the bios does NOT detect that the first hard drive it detects is bootable, if you have a Windows CD or DVD in a drive, you WILL NOT see a line "Press any key to boot from CD" or similar while booting - the initial files will start loading from the Windows CD or DVD automatically !
If you have more than one hard drive installed, at least one is bootable, at least one is NOT bootable........
The first hard drive the bios detects by default, or that it is custom set to detect first, may NOT be bootable.
The bios WILL NOT try to boot from another hard drive if the first one it detects is NOT bootable.
In that case, you need to
- go into the bios and find the list of hard drives. The hard drive that has a bootable partition must be made to be first in the list, Save bios settings.
- or - in some bioses, the Boot Order or similar list has more than one hard drive listed. The hard drive that has a bootable partition must be made to be first in the list, Save bios settings.
- or - you must change which data header the drive that has the bootable partition is connected to so the bios detects it first. If it's an IDE drive you may need to change a jumper setting on the back of the drive.
There are TWO ways you can get around XP not having any SATA drive controller drivers built into the contents of the Windows CD, and because of that, the intial files loaded from the CD not detecting any SATA drives.
Provide the SATA drive controller drivers to it,
OR change a setting in the Bios Setup.
Installing XP and SATA drive controllers, SATA drives; the SATA drive controller bios settings.

Some mboards have a main chipset that supports only the original SATA drive specs - max 1.5 gbits/sec. In that case, when you have a SATA II drive, max 3.0 gbits/sec, sometimes you need to install a jumper on the back of the drive in order for the drive to have a max speed of 1.5 gbits/sec, otherwise the main chipset won't detect the SATA II drive at all.
That DOES NOT apply to your main chipset.

"Sorry... had to edit this, I never noticed that you have no diskette drive."
Your computer case has no floppy drive installed in it, but your mboard has the floppy data header on it.
If you borrow a floppy drive and a floppy data cable from another computer, you can install the SATA drive controller drivers from a prepared floppy disk after pressing F6 near the beginning of loading files from the XP CD.
Or for that matter, you can buy a new floppy drive and floppy data cable cheaply, probably for under $20.
