Hello, everyone. I recently, out of curiosity, installed kali. I must have done something wrong because i now cant go back on windows--even when the cd where i have kali is removed, i still cant go back on windows, it only appears <<no operating system detected>> or something along these lines. My pc is almost without any memory left therefore i cant download windows into a pen drive and reboot. Tbh i just wanna go back to windows, it clearly was a mistake walking into an unkown land. What can i do
