Hey guys, I am having some issues with my PC. My main drive with my OS is SATA, as well as my DVD-RW. As of this morning, I received a "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" message when trying to turn on my computer. I checked my BIOS and the drive is not visible. I then tried to install the OS again on a new drive temporarily but my DVD-RW is not registering either. It is almost as if both SATA devices are not responding. I am using a Gigabyte motherboard with a Seagate 500GB hard drive and Lite-On DVD-RW. Please help.

When a SATA system drive and a SATA optical drive both disappear from BIOS at once, the most useful approach is to isolate power, controller, and device faults rather than guessing. The suggestions from , and cover basic resets and connection checks; the checklist below expands those ideas into a short, ordered diagnostic sequence and explains what each result means.

  1. Minimal-boot isolation

    • Remove everything nonessential. Connect only the Seagate 500GB to the motherboard port the manual marks as primary (SATA0/SATA1). Use a known-good SATA data cable and a direct SATA power plug (no splitters). Power on and note whether the drive spins and whether the BIOS lists it.

  2. Power-rail verification (safe methods)

    • If the drive does not spin, the power feed is suspect. Either swap in a known-good PSU or use a PSU tester/multimeter to check SATA-power pins: 12V ≈ 12.0V (acceptable ~11.4–12.6V), 5V ≈ 5.0V (~4.75–5.25V), 3.3V ≈ 3.3V if present. Use a meter only if comfortable with live measurements; otherwise swap the PSU.

  3. Device health check off-board

    • If the drive spins but BIOS still won’t see it, connect the drive to another working PC using a USB-to-SATA adapter or docking station and run a SMART check (CrystalDiskInfo/smartctl or dmesg/lsblk on Linux). A healthy SMART report points to a motherboard/controller issue.

  4. Motherboard/controller checks

    • Consult the Gigabyte manual to try ports tied to the primary chipset (some boards have additional controllers). Inspect the board for burnt marks or bulging caps and watch for POST codes or debug LEDs that indicate chipset faults.

  5. Workarounds and next steps

    • If drives are good but the on‑board controller is dead, a low-cost PCIe SATA controller will restore access. If the board is under warranty or shows physical failure, pursue RMA. If the drive itself is dead and data is critical, stop further testing and consider professional data recovery.

Safety/caution: observe anti-static precautions and avoid flashing BIOS or power probing unless comfortable doing so.

first thing i would try is set bios /setup to defaults and unplugging and reconnecting the sata cables ,

Firstly you just check your power supply.your system power create fluctuation then your Operating system automatically corrupt. just check your SMPS.

This is only happen when your SATA port is misplaced.

1. if your SATA cable damaged or breaked.
2. SATA port not detect by your BIOS/Motherboard.
3. Check your connection of both SATA wire ended are connected correctly.
4. Reset yout BIOS with Jumper setting.
