Windows Vista SP2 and Win7:

After the BIOS gets done posting, CHKNTFS checks the NTFS file system before proceeding to login. I would like to disable CHKNTFS, as this makes the boot process very long.

Simply you have to do CHKNTFS /X Your_Drive in command prompt, on next boot it won't check.

The X tells Windows to NOT check that particular drive on the next reboot.

That works fine for NTFS un-hidden partitions with logical drive designations, however virtually all laptop's like mine have a hidden OEM partition, (PQSERVICE for Acer's), which is used for Recovery and CHKNTFS doesn't support these with the /X option. So, I had to tweak a registry value to work around this limitation (See my answer below). – Frank R. Aug 6 '12 at 20:25

I had no problem disabling CHKNTFS for Drive C: with the /X option, however, CHKNTFS was still checking a hidden OEM partition with no visible DRIVE or volume name, so I wasn't able to disable it with /X.

Therefore, I had to modify the BootExecute registry value to autocheck autochk /k:* in order to disable all partitions, including the hidden one (see image below).

BTW, this tweak is done the same way for Win7.

BTW, if any of the partitions has problems, Windows will trap this exception and execute CHKNTFS to attempt to repair them. My laptop now gets to the login screen within 9 seconds from the time I power it up. You can manually run CHKNTFS whenever you choose to do so. – Frank R. Aug 6 '12 at 20:47
