0xc000000f故障：三星SSD未在启动优先级列表中显示，无法自动引导系统

Hey there, let's tackle this frustrating boot issue with your Samsung 860 EVO SSD together. First, I'll recap what you've already tried to avoid repeating steps:

• Created a bootable USB drive and ran fixmbr, fixboot, scanos, rebuildbcd via Command Prompt
• Manually booted from the SSD and attempted to adjust boot order using EasyUEFI
• Confirmed the SSD shows up in BIOS Boot Override but not in the regular Boot Priority list

Let's go through some targeted troubleshooting steps that might resolve this:

1. Double-check BIOS storage settings #

Head back into your BIOS and navigate to the SATA/Storage Configuration section:

• Make sure the SATA mode is set to AHCI (this is the standard for SSDs; switching from IDE might help the BIOS properly recognize the drive)
• Verify that the Samsung SSD is listed under connected storage devices here. If it's missing here entirely, the issue is likely physical or hardware-related (skip to step 3). If it shows up here but not in Boot Priority, move to step 2.

2. Force the BIOS to recognize the SSD as a bootable device #

Some motherboards require you to explicitly mark a drive as bootable or add it to the priority list manually:

• Look for an option like Add Boot Option or Create Custom Boot Entry in the Boot section of your BIOS
• When prompted, select the Samsung SSD and point it to the EFI boot file (usually located at \EFI\Microsoft\Boot\bootmgfw.efi for Windows systems)
• Save the changes and restart to see if the SSD now appears in the regular Boot Priority list

3. Check physical connections (don't overlook this!) #

Even though the drive worked fine for a year, loose connections can creep in over time:

• Power off your PC, unplug it, and open the case
• Disconnect the SATA data cable and power cable from the Samsung SSD, then reconnect them firmly
• Try swapping the SATA data cable with a different one (if you have a spare) or plugging it into a different SATA port on your motherboard
• Power the PC back on and check if the SSD shows up in Boot Priority now

4. Verify the SSD's partition structure with DiskPart #

Your EFI system partition might be corrupted or misconfigured, which could prevent the BIOS from listing it as a boot device:

• Boot from your USB recovery drive and open Command Prompt
• Run the following commands one by one:

  diskpart
  list disk
  select disk X  (replace X with the number corresponding to your Samsung SSD)
  list partition
  

• Look for a small (100MB-500MB) partition marked as EFI or System. If it doesn't exist, you'll need to recreate it. If it does exist, check that it's formatted as FAT32 and marked as active. You can repair it with:

  select partition Y  (replace Y with the EFI partition number)
  assign letter=Z:
  format fs=fat32 quick
  bcdboot C:\Windows /s Z: /f UEFI
  

  (Note: Replace C:\Windows with your actual Windows installation drive letter if it's different)

5. Share your SMART scan details #

You mentioned SMART1 and SMART2—could you share the full data from those scans? SMART stats can tell us if the SSD has developed bad sectors, read/write errors, or other health issues that might be causing recognition problems. If the SMART status shows "Failed" or critical warnings, the drive might be failing and need replacement.

6. Update your motherboard BIOS (advanced step) #

Outdated BIOS firmware can sometimes cause compatibility issues with SSDs. Before attempting this:

• Visit your motherboard manufacturer's website to find the latest BIOS version for your specific model
• Follow their instructions carefully (incorrect BIOS updates can brick your system)
• After updating, check if the SSD appears in Boot Priority

If none of these steps work, feel free to share your motherboard model, BIOS version, or screenshots of the BIOS storage/boot sections—this will help narrow down the issue further.
