DQACP is missing press Ctrl+alt+del to restart

Error Description:

Windows Server 2008 R2 operating system,

Desktop ThinkCentre m8400t

Today the boot suddenly prompts the following two lines:

DQACP is missing

Press Ctrl+alt+del to restart

It means: DQACP file is missing, restart by Ctrl+alt+del

Solution Idea:

First search, to see if others can not meet this problem;

Search results are very disappointing, it seems that the search engine is not omnipotent!

Reboot press F1 to enter BIOS, load default settings, save reboot, problem still;

Reboot press F12, select boot from hard drive, problem still;

Open the box test hardware, keep good habits, first to wash hands with tap water,

Remove the body of static electricity (it is said that the body's static electricity can reach thousands of volts);

Unplug the power cord, open the chassis, unplug all the memory, plug in the power, boot, there is no memory can not find the beep;

Shutdown, unplug the power cord, plug in memory, unplug the hard drive power cable and data cable, plug in the power, boot, error information changes;

Basically determine the problem and the hard drive, but still can't determine what exactly is the problem;

Unplug the power cord, plug in the hard drive power cable and data cable, plug in the power, boot;

Change the idea, since the hint file is lost, then use cabbage to do a U disk Startup disk, into the WinPE,

Create a file "DQACP" under the system's packing directory, unsure which directory the file should be in.

It is also copied to the Windows directory and the System32 directory, the boot, the problem is still;

Find Lenovo's technical support phone, 400-100-3000, customer service staff to determine the number of the factory, press F1 key can enter the BIOS, press F12 can display the boot device selection list, as well as prompted the error message to determine the system is a problem, recommend repair or reinstall the system.

Repairing the installation of the operating system is too long, and there are too many things to reinstall, too cumbersome to consider other solutions.

Final Solution:

Chinese cabbage u disk boot disk, into the WinPE,
