so my situation is i have a laptop that is in a continuous boot cycle once i restart this laptop it automatically goes to the gateway screen telling me it is attempting automatic repairs so this is not allowing me to enter the bios to change the boot manager so i can reboot a new version of windows on the comp also i have been trying to use the keystroke shift F8 to enter advanced options(safe mode) but i think it has to be used very early in the restart and im not getting any restart it automatically goes to my gateway symbol and thats it ... what canm i do to fix this
