Mnie się nie udało uruchomić w ten sposób trybu awaryjnego choć mam stosunkowo wolny sprzęt.
"What About F8 and SHIFT+F8?
If you're familiar with previous versions of Windows like Windows 7, Windows Vista, or Windows XP, you may remember that you could force the loading of what was then called the Advanced Boot Options menu by pressing F8. This is no longer possible in Windows 8.
In fact, even the widely publicized SHIFT+F8 option, which supposedly works to force Advanced Startup Options to appear (and ultimately Startup Settings and Safe Mode), only works on very slow computers. The amount of time that Windows 8 looks for SHIFT+F8 is so small on most Windows 8 devices and PCs that it borders on impossible to get it to work."
