Windows PC 直接進(jìn)入BIOS 而不啟動(dòng)操作系統(tǒng)，通常是由於啟動(dòng)配置更改或驅(qū)動(dòng)問題。 1. 首先檢查BIOS 中的啟動(dòng)順序是否改變，確保主硬盤為第一啟動(dòng)設(shè)備；2. 若硬盤被識(shí)別但無法啟動(dòng)，可能是Windows 引導(dǎo)程序損壞，需通過安裝U 盤運(yùn)行bootrec 命令修復(fù)；3. 若BIOS 完全未檢測(cè)到硬盤，可能為連接鬆動(dòng)或硬盤故障，需檢查硬件連接或運(yùn)行診斷工具；4. 此外，關(guān)閉Fast Boot 和Secure Boot 設(shè)置也可能解決問題。多數(shù)情況下，此問題可通過上述步驟逐一排查解決。

If your Windows PC is booting directly into the BIOS instead of loading the operating system, it usually means something has changed or gone wrong with your system's boot configuration. It might be a minor issue like a changed setting, or something more involved like a drive problem. Let's break down what could be happening and how to fix it.

1. Boot Order May Have Changed

One of the most common reasons your PC boots into BIOS is that the boot order has been altered. This can happen after a power outage, a BIOS update, or even if you plugged in a USB drive recently.

• Go into the BIOS (usually by pressing Delete, F2, or F12 during startup).
• Look for the "Boot" tab or similar section.
• Make sure your main hard drive or SSD is selected as the first boot device.
• Save changes and exit.

Sometimes, just reordering the drives fixes the issue immediately.

2. Windows Bootloader Might Be Missing or Corrupted

If your PC recognizes the drive in BIOS but still doesn't load Windows, the bootloader could be corrupted or missing. This often happens after a failed update, improper shutdown, or disk-related issues.

You'll need a Windows installation USB or recovery drive to fix this:

• Insert the USB and boot from it.
• Choose your language and click “Repair your computer.”
• Go to Troubleshoot > Advanced Options > Command Prompt.
• Run these commands one at a time:
  • bootrec /fixmbr
  • bootrec /fixboot
  • bootrec /rebuildbcd

These steps will attempt to repair the boot files so Windows can start normally.

3. Hard Drive Might Be Failing or Disconnected

If the drive isn't detected at all in BIOS, it could be physically disconnected or failing. This is more common in desktops where cables can loosen over time, or laptops that have been moved roughly.

• Shut down the PC and open the case (if comfortable doing so).
• Check SATA or NVMe connections to ensure the drive is properly seated.
• If the drive is old, it may be showing signs of failure — listen for unusual noises or check for slow performance when it does show up.

You can also run hardware diagnostics through your motherboard manufacturer's tools or the drive manufacturer's utility.

4. Fast Boot or Secure Boot Settings Might Be Causing Issues

Windows uses a feature called Fast Boot to speed up the startup process. But sometimes, especially after an update or driver change, it can interfere with the normal boot sequence.

• Enter BIOS and search for “Fast Boot” — disable it temporarily.
• Also, check Secure Boot settings. If it's enabled but your OS doesn't support it (or if it's misconfigured), that could prevent Windows from loading.

Try disabling both options and see if your system boots normally afterward.

It's usually not a major disaster if your PC boots into BIOS — more often than not, it's a simple configuration issue. Start with checking the boot order, then move on to verifying drive health or rebuilding the bootloader if needed.

基本上就這些。
