Avast, ESET, Symantec anti-virus products were noticed as the cause of the error, but it may well occur with other programs. After removing the antivirus, be sure to restart the computer. Attention: The same effect can have utilities for cleaning a computer and registry operating in automatic mode, remove them too.
- Disconnect all external drives from the computer and all that are not required to operate the device connected via USB (including card reader, printers, gamepads, USB hubs and the like).
- Perform clean Windows loading and try updating in this mode. Read more: Net loading of Windows 10 (the instruction is suitable for clean downloads of Windows 7 and 8).
- Check if there is enough free space on the hard disk system section (disk C). Ideally, have 20-30 GB free. See How to Clean the C disk from unnecessary files, how to enlarge the disk C due to the disk D.
- If the error appears in the update center, then try to update to Windows 10 using the update tool to Windows 10 from the Microsoft site (though, it can issue the same error if the problem is in drivers, disks or programs on the computer). More This method is described in the update to Windows 10 instructions.
If nothing has done from the specified one, go to more time-consuming methods (while not in a hurry to install the previously remote antivirus and connect external drives).

Additional ways to correct the problem
If nothing of the described above helps, try the following options, perhaps, they will be in your particular situation.
- Remove the video card drivers and the accompanying software video card using Display Driver Uninstaller (see how to delete video card drivers).
- If the information about SAFE_OS is present in the error text during BOOT operation, then try to disable Secure Boot in UEFI (BIOS). Also, the cause of this error can be enabled encryption of BitLocker discs or otherwise.
- Check the hard disk using CHKDSK.
- Press Win + R and enter diskmgmt.msc - see if your system disk is a dynamic disk? This can call the specified error. However, if the system disk is dynamic, it will not be possible to convert it to the basic data without loss. Accordingly, the solution here is a clean installation of Windows 10 from the distribution.
- If third-party disk encryption tools or a program like crypto pro are installed on your computer, they can cause this error, in particular, with the code 0x40017 Second_Boot. Disable third-party encryption, remove this kind of utility. For crypto, it may not be deleted, but a simple update of the program.
- For some old motherboards, equipped with the FireWire IEEE 1394 controller helps its shutdown to the BIOS.
- In some cases, correct the error helps to disconnect the Intel VT-X / VT-D or AMD-V technologies in the BIOS.
- If you have Windows 8 or 8.1, you can try the following actions (after saving important data): Go to update and restore settings and run Windows 8 (8.1) reset after the procedure is completed without installing any programs and drivers, try trying Run the update.
