I own a reliable HP Pavilion dv5 Notebook that served me well for 9 years. The past four days I've been working on it unstalling/reinstalling programs, and running diagonostics. The forth day I decided to shut it down for 2 hours, until I decided to power it on. Once I powered it on, I was met with this error: 0xc000000e The boot selection failed because a required device is inaccessible. Out of curiosity, I ran a quick primary hard drive scan - once it hit 98% another error read: Replace Hard Disk 1. Obviously I must replace the HDD, but once I do that must I start from scratch? Tried booting up windows from a USB and that didn't work as well.
