How to start your PC in Safe Mode: Windows 7
The easiest way to start Windows 7 in safe mode consists in turning on the computer and, immediately after the appearance of the logo or the initial message of the BIOS, repeatedly press the key F8 on the keyboard until the screen dedicated to advanced boot options appears.
Again, you can use multiple variations of Safe Mode - that one classical, the one equipped with network support (the drivers for the network cards on the computer are loaded) and the one with Command Prompt, which allows you to use only the latter utility.
Having made your choice, move to the option you want using the arrow keys on the keyboard and, to start it, press the key Submit.
If you are unable to enter Safe Mode this way and your computer successfully starts Windows 7, you can achieve the same result by acting from the Command Prompt, as I will explain in one of the later sections of this guide.
How to start your PC in safe mode from the BIOS
You need boot the PC in safe mode from the BIOS, as you are unable to log into Windows normally and are unable to act from within the operating system? In this case, you will be happy to know that Windows 8.1 and Windows 10, following two consecutive failed boot attempts, automatically carry out a series of preliminary checks immediately after the BIOS; when finished, both operating systems show a console containing recovery options, which you can use to boot into safe mode.
So all you have to do is wait for it Windows tries to boot (and fails) two times in a rowuntil you see the wording appear on the screen Preparing for automatic recovery; if this does not happen, you can "cause" a failure to boot the operating system by cutting off the power when the Windows logo appears. This last path, however, is quite risky and should not be followed except in cases of extreme necessity.
Immediately after starting the automatic recovery, a series of diagnostic checks will be carried out, after which the recovery console should appear: then press the buttons Advanced options e Troubleshooting, then access the safe mode by acting in a similar way to what I indicated above.
Su Windows 7instead, the problem does not arise, as it is possible to access the safe mode by repeatedly pressing the key F8 of the keyboard immediately after the appearance of the BIOS POST message, as I explained to you in the dedicated chapter of this guide.
How to start your PC in Safe Mode with Command Prompt
Another good way to quickly start your computer in safe mode involves using the Command Prompt (or of PowerShell): by giving a specific instruction, in fact, it is possible to directly access the computer diagnostic options.
How? I'll explain it to you right away. To get started, open the Command Prompt calling it from the folder Windows system / Accessories visible in the Start menu, type the command shutdown -r -o in it and press the key Submit keypad to confirm.
Following this operation, the computer will restart and will offer you the boot options screen: therefore, if you use Windows 10 o Windows 8.1, you will need to click on the button first Troubleshooting, Then Advanced options and, in no time, his Startup Settings e restarting. On the next reboot, press the key 4 on the keyboard, to activate the safe mode, or the key 5, to enter Safe Mode with Networking.

In case of problems
How do you say? You managed to get into safe mode but the problem you encountered is still there, or worse still, your copy of Windows is completely corrupt and you can't activate the aforementioned mode, even after following all the instructions I have given you ?
In this case, you may have to go down a more drastic route and restore or format your computer: fortunately, Windows 10 allows you to do this in a fairly "painless" way, by intervening only on the details relating to the operating system (installed programs and settings system) and leaving your personal files untouched. If yours is a notebook, however, there may be manufacturer recovery software available, which allows you to restore your computer to its factory state in just a couple of clicks.
