If u install partially of ur hewlett packard recovery disks?

will everyting b erased? wat can i get bak?

Answers:

If you started the destructive recovery and quit - everything is lost - it does a format (erase) until that time it starts to reinstall the operating system again.
Professional equipment might be able to retrieve some files (doubtful because of individual wrote over) - and a high cost.
Your one and only choice might be to finish the destructive recovery.
