So i started to build a pc about a week ago and i was looking/buying for computer parts and luckily i found a HDD in my old pc and i tried to use it. It worked and i tried to clean some junk files but it was so many and i decided to format the drive. I search google how to format it and i followed the instructions by using the command prompt i dont remember it but it was something like diskpart stuffs and when i finished formatting it i saw in the instructions "youre done! all you have to do is to format it to ntfs or fat32" i dont really got it but i tried to formst it to ntfs (f = ntfs, i dont remember) but the process was too slow so i cancelled it (idk why probably because i dont get it) so i restarted my pc and the "Reboot and select proper boot device or insert boot media in selected" showed up and i tried many things like boot ordering in the bios and i dont know what to do now. please i need help. Thank you
