When you are facing a computer that just won't boot, you have three options, listed in order of easiness.
Option 1: Startup Repair
Running Startup Repair solves nearly all of your problems. To run Startup Repair, tap the F8 key continuously until you see a screen with a list of boot options. Highlight 'Repair Your Computer' and hit 'Enter'. Once you're in Startup Repair, simply follow the onscreen instructions and you'll be back in your PC in a few minutes! However Startup Repair may not work, in that case, follow the instructions in Option 2.
We recommend booting from a Windows PE DVD/CD when your system doesn't boot and Startup Repair fails. Simply download the ISO, burn it to a disc and boot from it. Then you can explore the contents of your C drive and copy those files in to an external medium such as a 1TB HDD.
A link to a website which tells you how to download the ISO is available here.
If you have any questions about this process, don't hesitate to contact us. Once again, sharing is caring.
