查明系统 (Windows) 是使用 BIOS 启动还是使用 Python 3 启动 UEFI

Question

如何确定 Windows 是使用 UEFI 启动的，还是使用 Python 启动的 BIOS？

Answer 1

根据this website，你可以这样做：

• 备选方案 1： 读取命令输出

import subprocess

out = subprocess.check_output(['bcdedit']).decode('utf-8')

is_loader = False
for line in out.split('\n'):
    # Ignore lines until the Windows Boot Loader section
    if not is_loader and 'Windows Boot Loader' in line:
        is_loader = True

    if not is_loader:
        continue

    # Ignore lines until the path subsection
    if not line.startswith('path'):
        continue
    
    # Receives 'EXE' (BIOS) or 'EFI' (UIEF)
    boot_type = line[-3:].upper()
    
    # You can also use an if-else expression
    # Receives 'BIOS' or 'UIEF'
    # boot_type = 'BIOS' if line[-3:] == 'exe' else 'UIEF'

• 备选方案 2：读取日志文件

import re

with open(r'C:\Windows\Panther\setupact.log') as f:
    pattern = re.compile(r'Detected boot environment: (\w+)')

    # Iterate over every line of file until finds a match
    for line in f:
        match = pattern.search(line)
        if match:
            # Receives 'BIOS' or 'UEFI'
            boot_type = match.group(1).upper()
            break
