The 0xc0000185 error typically occurs after a system restart as a blue screen of death, indicating that normal system entry is not possible.

2. How to use Renee PassNow to transfer or recover data?

When your computer cannot start normally due to a blue screen failure, you can create a startup disk through Renee PassNow. Then use the functions provided by the software to transfer or restore data. Specific steps are as follows:
Step 1: Download and install Renee PassNow on other computers that can log in and run normally, connect the USB disk to the PC, run Renee PassNow, and select “Create a Live USB” in “Step 1: Select the creation method”. (Note: Ensure important files in the USB disk are saved in other locations before proceeding, as this operation will delete all data in the USB disk.)
Step 2: Select (x64) or (x86) based on system type, click (Download Now) to download the ISO file, then click (Create USB) and (Eject USB) after download.

III. How to fix 0xc0000185 error code?

1. With the help of the computer's startup repair function

The built-in startup repair function in the Windows system recovery environment can solve the problem of the computer not entering the system normally. Let’s learn the method below:
Step 1: Insert the Windows installation disk and set the first boot sequence in BIOS to start the computer from the installation disk. Select “Repair your computer” on the Windows Installer screen to enter the recovery environment.

2. Use the Bootrec command to repair BCD

BCD (Boot Configuration Data) contains essential information for Windows to boot. If damaged or missing, it can prevent proper loading. The Bootrec command can repair damaged master boot records or BCD files, requiring entry into the recovery environment to operate. Follow these steps:
Step 1: Insert the Windows installation disk into the computer and set it as the first boot sequence in BIOS settings. Save the settings and start the computer from the installation disk to install Windows. Select the “Repair your computer” option on the “Install Now” interface to enter the recovery environment.

3. Use Chkdsk to check system hard disk errors

Chkdsk is a practical tool for Windows to check the disk status, memory status, and specified files in a specified path. It can also repair disk errors and help resolve blue screen errors related to the hard disk.
Step 1: Connect the Windows installation disk to the computer and change the boot sequence preference in the BIOS settings to the Windows installation disk.
Step 2: After successfully booting the computer from the Windows installation disk, select the “Repair your computer” option in the lower left corner of the installation interface to enter the recovery environment.
