Hard drive not show on boot sequence menue and got NTLDR doesn't exist

[franky santa]

Hi,
I've using my desktop for a couple of years. Last night I installed software downloaded from cnet.com. I don't think there softwares would have viruses.

Anyway, this morning I started my PC and got the "NTLDR is missing".
I have a raid system FYI.
Here is what I've done so far.
Check bios and saw that HD is not in boot sequence. However, the drives are detected under the drives secton in bios.
Ran my win XP cd to do repairs such as:
copy NTLDR, fixboot, chkdsk. I did this on the C prompt.
None of them worked as my HD aren't recognize

I check to see if any of the cables were loose and reseated them. None were loose.

Now after this, the win xp when pressing R for repair doesn't go t c:\ and says in can't find HD.

I've put the HD as a slave disk and connect to another PC and I'm able to see all files, access them, and open them.

I've connected another HD (IDE) (current HD are SATA) to the problem PC. The boot sequence in bios sees IDE HD but still can't boot.
Any suggestions that I've done yet would be appreciated.

I think your motherboards battery needs to be replaced. You shouldn't be able to see the drives in the bios as you would need to enter the raid menu to see them with your ports in raid mode.

When your battery gets too weak it resets the bios when you turn it off and would revert you back to default which is probably compatibility or ide mode.

Hi Popatim,
Before everything went wacky, I see the raid menu. Although I don't know if the SATA drives where ever seen in the bios menu. So I don't have a reference. I'll try to change the battery. However, would a weak battery cause and "NTLDR is missing". This was the first error I saw.

BIOS resetting should not have caused NTLDR missing error. It does not seem logical. How many drives do you have in RAID configuration pl?
