My friend was attempting to go back to his original OS from WIN10 and the laptop died during the process. After booting we recieved error code 0xc00000605 upon start telling us a component is missing and we needed to repair. i got us a windows recovery disk and tried to boot it from the bios but i am unable to do anything in the bios except change the system date and time. If i could just boot it from the dvd i would be okay, any suggestions? laymans terms please!
