[computernoobz]

Hello,
How to fix the error above
You see It started with AVAST Anti virus it expired so then I unistalled it then Downloaded and installed AVG Internet security then i made some registry tweaks then rebooted my laptop then when I rebooted my laptop errors started to occur so I decided to run startup repair and system restore , no luck it both failed then i tried going to safe mode and last known good configuration but then it just directed me to a blue screen with errors and stuff and reboots again and again then i turned my laptop off . I turned it on again then tried formatting my hard drive with command prompt but I formatted the wrong one then the error on the title occured What can I do to Fix This?.

I'm Using HP laptop

It sounds like your only option at this point is to reload the OS.

Your laptop most likely came with software to create a restore disk. This should be the 1st option to use when purchasing a laptop. The laptop manufacturer may provide you with a restore disk for a slight fee.

Don't mess with the registry unless you know what you are doing. The system restore put your registry back to the way it was - the problem being that you uninstalled avast and now the registry once again contains keys for avast. The second mistake was formatting the wrong disk and it most likely contained the boot loader, thus the error message you are now getting.

The Restore Disk Was for Windows XP lolz.

 

[computernoobz]

I only have two laptops One is Windows XP and the other one is Windows 7 the one I broke. So I don't think any of the solutions will work , will it?

That would be your best bet. Learn and live next time you will be better prepared. Always have a way to restore the OS before you do anything else. It is a hard lesson but happens to the best of us at one time or another.
