我的Win PC靴子直接进入BIOS设置实用程序

首先检查BIOS中的启动顺序，确保Windows硬盘被设为第一启动设备；2. 若硬盘未显示，进入BIOS的存储或主界面确认硬盘是否被识别，若未识别则检查SATA/M.2连接、更换数据线或测试硬盘于其他设备；3. 确认启动模式（UEFI/Legacy）与Windows安装模式匹配，建议关闭CSM启用UEFI仅模式；4. 若硬盘被识别但仍无法启动，使用Windows安装U盘进行启动修复，执行bootrec命令修复引导；5. 若BIOS频繁重置，更换主板CMOS电池并恢复BIOS默认设置。问题通常因硬盘未被检测或启动配置错误导致，通过逐一排查硬件连接、BIOS设置和引导修复可解决，最终使系统正常加载操作系统。

If your Windows PC is booting directly into the BIOS setup utility instead of loading the operating system, it usually means the system isn’t detecting a bootable drive. This can be caused by hardware, configuration, or software issues. Here’s how to diagnose and fix it:

? 1. Check Boot Order in BIOS

The most common cause is an incorrect boot order.

• When the PC starts, you’re already in BIOS — look for a tab labeled Boot, Startup, or Boot Priority.
• Make sure your Windows drive (usually an SSD or HDD) is listed as the first boot device.
• If the drive doesn’t appear in the boot list at all, that’s a sign the system isn’t detecting it — skip to section 2.
• Save changes and exit (usually F10).

? Tip: Some systems list drives under UEFI or Legacy mode — ensure you're using the correct mode that matches how Windows was installed.

? 2. Verify the Drive Is Detected

Even if it's not booting, the drive should still appear in BIOS.

• In the BIOS, navigate to the Main or Storage tab.
• Look for a list of connected drives (SATA or NVMe).
• If your drive does not appear, possible causes include:
  • Loose or faulty SATA/M.2 connection
  • Failed drive
  • Disabled SATA port in BIOS
  • M.2 slot powered off or set to wrong mode (e.g., PCIe vs SATA)

? What to do:

• Power off the PC, unplug it, and reseat the drive (especially for M.2 or SATA connections).
• Try a different SATA port or cable (for SATA drives).
• For M.2 drives, ensure the BIOS hasn’t disabled the slot — check under Advanced > Integrated Peripherals or similar.
• If you have another PC, test the drive there.

? 3. Check for Boot Mode Conflicts (UEFI vs Legacy)

Windows usually installs in UEFI mode, but if BIOS is set to Legacy/CSM, it may not recognize the boot drive.

• Go to Boot or Advanced Mode in BIOS.
• Look for Boot Mode or CSM (Compatibility Support Module) settings.
• Set it to UEFI Only (disable CSM if possible).
• Save and exit.

?️ If Windows was installed in UEFI mode but CSM is enabled, or vice versa, the boot loader won’t load.

? 4. Drive Is Detected But Still Won’t Boot?

If the drive shows up in BIOS but the system still skips it and opens BIOS again:

• The bootloader may be corrupted.
• Or the Windows installation is damaged.

?️ Try this:

1. Boot from a Windows installation USB.
2. Choose Repair your computer > Troubleshoot > Advanced Options.
3. Run:
   • Startup Repair
   • Or use Command Prompt:

     bootrec /fixmbr
     bootrec /fixboot
     bootrec /scanos
     bootrec /rebuildbcd

4. Reboot and see if it now boots normally.

? 5. BIOS Keeps Resetting or Auto-Opens Setup

If the system always opens BIOS instead of booting, even after saving settings:

• CMOS battery might be dead (the small coin-cell battery on the motherboard).
  • Replace it (usually a CR2032).
• BIOS settings aren’t saving — reset BIOS to defaults (Load Optimized Defaults), then reconfigure boot order.
• Some motherboards open BIOS if they detect no bootable device — so fixing drive detection usually resolves this.

Summary: Quick Checklist

• ✅ Drive appears in BIOS under storage devices?
• ✅ Correct boot order set (drive is first)?
• ✅ Boot mode matches installation (UEFI vs Legacy)?
• ✅ Drive is properly connected and powered?
• ✅ CMOS battery is good and settings are saving?

If the drive is dead or corrupted, you may need to replace it and reinstall Windows. But in most cases, it’s a simple BIOS configuration or connection issue.

Basically, if the PC boots straight into BIOS, it’s saying: “I don’t see anywhere to boot from.” Your job is to help it find the drive — either physically, electrically, or logically.
