I use this batch file to do a file system check with reboot:

@python -x "%~f0" "-*- Python -*-" & goto :EOF

# Initiate an immediate reboot which will check all local drives

import win32api
import win32con
import win32file

value = []
drives = win32file.GetLogicalDrives()
for drive in range(26):
	if drives & (1 << drive):
		letter = chr(65 + drive)
		if win32file.GetDriveType(letter + ":\\") == win32file.DRIVE_FIXED:
			value.append("autocheck autochk /p \\??\\" + letter + ":\0")
value.append("autocheck autochk *\0")
value.append("\0")
key = win32api.RegCreateKey(win32con.HKEY_LOCAL_MACHINE, "SYSTEM")
key = win32api.RegCreateKey(key, "CurrentControlSet")
key = win32api.RegCreateKey(key, "Control")
key = win32api.RegCreateKey(key, "Session Manager")
win32api.RegSetValueEx(key, "BootExecute", 0, win32con.REG_MULTI_SZ, value)

from ntsecuritycon import *
import win32security

def AdjustPrivilege(priv, enable = 1):
	# Get the process token.
	flags = TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY
	htoken = win32security.OpenProcessToken(win32api.GetCurrentProcess(), flags)
	# Get the ID for the system shutdown privilege.
	id = win32security.LookupPrivilegeValue(None, priv)
	# Now obtain the privilege for this process.
	# Create a list of the privileges to be added.
	if enable:
		newPrivileges = [(id, SE_PRIVILEGE_ENABLED)]
	else:
		newPrivileges = [(id, 0)]
	# and make the adjustment.
	win32security.AdjustTokenPrivileges(htoken, 0, newPrivileges)

def Reboot(message = "Rebooting", timeout = 30, bForce = 0, bReboot = 1):
	AdjustPrivilege(SE_SHUTDOWN_NAME)
	win32api.InitiateSystemShutdown(None, message, timeout, bForce, bReboot)

Reboot(timeout = 0)
