Hey guys today i open my pc to put a hard drive in because i had came loosen. Then i plug my pc back up and it says NTLR missing press ATL+Crl+del to restart so i did that and it came back up it. I am on my labtop know. SO what should i do? PLease help me. It keeps saying NTLDR missing

did you put a new hard drive in our just plugged the old one back in?

But i plug it back in

if it is still unplugged you have to plug it back in!

i did i plug everything i unplug back in and i did not put a new hard drive

OK you need to go back in there and make sure evryting is plugges in! That is pretty much your problem.. Your hard drive cable must have came loose. It can't find the hard drive... Or the boot order got messed around.. Do you have your boot order like this Hard Drive/CD/dvd/rom/Floppy Drive

let me check how do i check? all the wires are plug in that i can see. It was very drusty in there i might need to dust it out
