One way to reach safe mode is by booting up and pressing the F8 key right after the POST check. In practice this can be tricky to time correctly and all too often you can end up in the regular boot mode. The technique is to repeatedly tap the F8 key until the startup menu appears. Sometimes you will fill up the buffer memory with all the key taps and get an error message or the computer will complain by beeping. Also, the F8 key may not work with a USB keyboard because USB drivers have not yet been loaded. However, newer computers have USB support in the BIOS so this problem should be limited to older machines.
When you successfully initiate the boot options selection, the window shown below will open. The menu provides a number of advanced options. The default selection is "Start Windows Normally" and is highlighted. To open in Safe Mode, use the up arrow key to select it and then press the Enter key.
