I followed a video and reached the step where you put linux mint in pendrive then boot using the pendrive to install the OS. I did not turn off the bitlocker so i could not install it at that time. I removed the pendrive. Then i turned off device encryption hoping it would solve the bitlocker problem. Then i deleted everything from the pendrive to have a fresh start. Then i followed same steps and when i tried to boot my pc this error showed up. Please help me i really wanna switch to linux. Pc is lenovo ideapad slim 5
