Change the CHKDSK countdown time
When you schedule CHKDSK to run
at the next boot, the system will prompt you to press a key to cancel the
operation while CHKDSK is running. The system will display a countdown during
that cancel period. The default value is 10 seconds. To Change this open up
Regedit and locate:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\AutoChkTimeOut
You can change the value to
anything from zero to 259,200 seconds (3 days). With a timeout of zero, there
is no countdown and you cannot cancel the operation
