So the problems arose when I kept getting an error when I tried to start my computer. The error read No bootable device when I had a hard drive with an OS that previously worked. The error would occur 50/50 the other times it would start windows. Windows was very slow and kept on giving me the blue screen of death, so I decided to reset my windows. Each time I tried to reset windows it wouldn't let me reset it kept giving me an error. Then I decided to just put the windows installer on a flash drive and format the drive. It gives me an error about no partition or something, but I fixed that and I proceeded to install windows. During the installation, an error came up that took me to the installation screen again and it said windows cannot be installed on this partition. Does anyone know how to fix it? Is there a problem in the BIOS or is there a problem in the physical hard drive?
