Windows 7 Boot takes 20+ minutes, Help!!!

About two week ago my Samsung All-in-one PC started taking about 20 minutes to boot up from a normal shutdown. The first screen that comes up is the F2/F4 screen which does not change for about 10 minutes. Then the screen goes black and the only thing on the screen is the cursor at the top left of the screen. It stays on that screen for about another 10 minutes, and eventually Windows comes up. After Windows comes up, all processes work fine. I checked the system log and the last entry after the boot started and before Windows came up was an entry for Kernel-General at 11.30.34 with event-ID of 13 and the next log entry was at 11.56.16. This boot took 26 minutes because I pressed the F4 key during the process.

Thanks for the info, Golden. I removed all the startup tasks and still have the same problem. Any ideas????

Disable system restore and retry. Disable System Restore in Windows 7

Long startup time may be either old restore points or driver.

If you have installed a new peripherical recently you can remove it to see if it resolve the problem. If a driver update have been made you could revert back to the old driver using devices manager too.

You should take a look at hard drive health too. Failing hard drive can become very slow. Use Hard Disk Sentinel Pro evaluation to have a quick look at the hdd health. If everything is fine, you could verify system file :

SFC /SCANNOW Command - System File Checker

Also do a disk check :

While you are in Windows, try "System File Checker" see the following link;

SFC /SCANNOW Command - System File Checker
(run it 3 times)

If the problem still exists it may be caused by the firmware or chipset drivers requiring an update.

HTH

Either HDD or SATA controller or even SATA cable might be faulty as well.
If you're sure hdd is fine try another controller and/or different SATA cable.

But first make sure SATA cable is firmly attached to both drive and controller.
It could simply got loose somehow.

Yes, would be a better idea to try a system restore before disabling it altogether
