python
import os
def fix_boot_ini():
# Check if the boot.ini file exists
if not os.path.exists("C:\boot.ini"):
print("Boot.ini file not found!")
return
# Read the contents of the boot.ini file
with open("C:\boot.ini", "r") as boot_ini:
lines = boot_ini.readlines()
# Check if the boot.ini file is invalid
if not any(line.startswith("multi") for line in lines):
print("Boot.ini file is already valid!")
return
# Remove the invalid line(s) from boot.ini
valid_lines = [line for line in lines if not line.startswith("multi")]
# Write the updated boot.ini contents
with open("C:\boot.ini", "w") as boot_ini:
boot_ini.writelines(valid_lines)
print("Boot.ini file has been fixed!")
# Call the function to fix the boot.ini file
fix_boot_ini()
This code checks if the boot.ini file exists, reads its contents, and then removes any invalid lines that start with “multi”. It then writes the updated contents back to the boot.ini file. However, please exercise caution and ensure you understand the risks before using such a tool.
