Stick PC需升级64位Windows 10，无法从USB启动反复重启求助

Hey there, let's tackle this frustrating boot issue you're having with your Stick PC. Even though your CPU supports 64-bit, these tiny devices often have quirky BIOS/UEFI limitations that block standard boot media. Let's walk through practical fixes step by step:

• Verify BIOS/UEFI Boot Mode & Secure Boot Settings
  Most Stick PCs default to either Legacy BIOS (MBR) or UEFI (GPT) mode, and mismatches with your USB drive's format can cause instant restarts. Here's what to check:

  1. Reboot your device and hit the BIOS access key (common ones for Stick PCs are F2, Del, Esc, or even a tiny reset button you press with a pin during boot).
  2. Navigate to the Boot section and check if your current boot mode is Legacy or UEFI.
  3. If your USB drive was created for UEFI, try switching to UEFI mode; if it's Legacy, switch to that instead.
  4. Also, disable Secure Boot if it's enabled—even signed Windows media can run into compatibility issues with low-power device BIOSes.

• Recreate the Boot USB with Microsoft's Official Tool
  Generic boot drives sometimes fail on Stick PCs because they don't account for the device's specific hardware quirks. Use the Media Creation Tool for a more compatible drive:

  1. On a working PC, launch the Media Creation Tool.
  2. Select "Create installation media (USB flash drive, DVD, or ISO file) for another PC".
  3. Choose 64-bit Windows 10, then select your USB drive. Let the tool handle partitioning automatically—this creates a drive that works with both Legacy and UEFI modes.

• Check USB Port Compatibility
  Stick PCs often have limited USB 3.0 support in BIOS. If your boot drive is USB 3.0/3.1:

  • Try plugging it into a USB 2.0 port (if available).
  • Or, in BIOS, look for a setting like "USB 3.0 Compatibility Mode" and switch it to USB 2.0 mode to improve compatibility.

• Reset BIOS/UEFI to Defaults
  Custom BIOS settings can sometimes interfere with boot. Find the "Load Defaults" or "Restore Factory Settings" option in your BIOS, apply it, then reconfigure the boot order to prioritize your USB drive.

• Upgrade Directly from Your Current 32-bit System
  Since you can still boot into your existing 32-bit Windows 10, skip the USB boot entirely and upgrade in-place:

  1. Mount your 64-bit Windows 10 ISO file (right-click the ISO and select "Mount").
  2. Open the mounted virtual drive and run setup.exe.
  3. Follow the prompts—you can choose to keep your files/apps or do a clean install. This method bypasses BIOS boot restrictions entirely.

If none of these work, it's possible your Stick PC's BIOS has a hard lock on 64-bit boot (even though the CPU supports it). Check the manufacturer's website for BIOS/firmware updates—sometimes they release patches to unlock this functionality.
