I have a Dell Precision 360 desktop. It works just fine in every way, except that at the beginning of the boot process, right after the bios screen, I get a message that says:

"Primary drive 0 not found. Strike the F1 key to continue, F2 to run the setup utility."

If I hit F1 it boots up just fine. Perhaps I should just be happy with that, but it's getting annoying since I always have to hit that key during the boot process.

If I hit F2 it takes me into the setup process. What's interesting here is that if I go to change the Primary Master Drive settings it is set to "auto" but then it says "Unknown Device." However, it recognizes the CD-ROM drive just fine.

I don't believe it is a dead bios battery because the settings are saved. It just appears that my hard drive isn't being recognized as the primary master for some reason and I'm not sure why.

The jumper is set to "master" on the hard drive currently, but I have tried it in other spots to no avail.

A few practical checks and safe fixes that build on and ’s points. The symptom is a BIOS failure to identify the hard disk at POST while Windows still boots after pressing F1 — that usually means the drive is present but not responding in time or not being seen on the expected IDE connector. Common, non-destructive causes are cable/jumper placement, a marginal power connection, or the BIOS timing/auto-detect failing.

  • Power down and unplug, then reseat the 40‑pin IDE ribbon and the drive Molex power plug. Put the HDD on the end connector (the “master” position of the cable) and the optical drive (if present) in the middle. Swap the ribbon with a known-good cable if available. Inspect the motherboard header and cable for bent pins or damage.
  • Verify jumpers for master/slave/cable-select. If only one drive is on a cable, use the drive’s “master” or single-drive position per the label. If two devices share a cable, set one master and the other slave (or both cable-select when the cable supports CS).
  • In BIOS, set IDE detection to Auto (or re-run Auto-Detect). Look for options like “Delay for HDD spin‑up” or change “Halt On” so the system doesn’t stop for a non-fatal drive detect message while troubleshooting.
  • Boot into Windows and immediately back up critical data. Run a SMART check and the drive manufacturer’s diagnostics (bootable tool) to rule out intermittent hardware failure. Swap the drive to a different IDE channel or try a known-good drive to isolate whether the motherboard channel is flaky.
  • If the drive and connections test good but the message persists, consider a BIOS update from Dell (follow their instructions exactly) or a replacement IDE cable/power lead. Updating BIOS is a last step and requires a verified BIOS file and backups.

These steps expand on ’s cable advice and ’s drive-order suggestion while emphasizing data backup and diagnostics before replacing parts or flashing firmware.

what does the bios show for the secondary ide,have you made any changes inside with the drives ribbon cableperhaps plugging it into the secondary ide plug by mistake .

Do you have more that one hard drive? If so, Then perhaps the one attached to the Drive 0 cable is not the one with the main windows install. F1 may be telling the bios to look on the next drive Drive 1,2,etc.

I once had four hard drives and the main boot was on Drive 3. I swapped the physical drive to the Drive 0 cable and all was good.
