«The computer is running correctly» or «it Seems that Windows did not load properly»

Logo appears Windows 10 and the computer turns off

Unfortunately, in this situation we are not able to get into the Windows recovery environment 10 present on the hard disk, and therefore we will need either the recovery disc or bootable flash drive (or disk) with Windows 10, which will have to do on any other computer (if you have such a drive missing).

Details on how to boot into recovery environment using the installation disc or stick in the guide Disk recovery Windows 10. Once booted into the recovery environment try the methods in the section about «running correctly».

The Boot Failure and error An operating system wasn’t found

Another common variant of the problem with the launch of Windows 10 — the black screen with the error message Boot failure. Reboot and Select Proper Boot device or insert boot media in selected boot device, or An operating system wasn’t found. Try disconnecting any drives that don t contain an operating system. Press Ctrl+Alt+Del to restart.

Black screen when launching Windows 10

The problem is, when Windows 10 does not start, and instead of your desktop you see a black screen, has a few options:

  • When apparently (for example, a sound of welcome OS), in reality, it starts, but you see only a black screen. In this case, use the manual Black screen Windows 10.
  • When after some action with the drives (partitions) or abnormal you see first the logo and then black screen and nothing else happens. As a rule, the reasons for this are the same as in the case INACCESSIBLE_BOOT_DEVICE, try to use the methods from there (the instruction pointed out above).
  • Black screen, but the mouse — try the suggestions from the article does Not load the desktop.
  • If after switching on does not appear in either of Windows logo 10 or even the BIOS screen or the manufacturer logo, especially if you otherwise had trouble starting the computer the first time, you will need the following two instructions: the Computer will not turn on, will Not turn on the monitor — I wrote them quite a long time, but in General they are still relevant now and will help to understand what exactly the case (and it, probably, not in Windows).

It’s still all I’ve managed to systematize most common user problems with the launch of Windows 10 at the current time. Additionally I recommend to pay attention to the article Restore Windows 10 — perhaps it can also help in solving the described problems.
