Question

I copied all the contents of a hard drive to another. It wont boot of it though. I need it to. I deleted a partition and used a data recovery, The files i copied were the recovered ones. It recovered EVERY file.

Answer 1

You will find (possibly among other problems) that it did not reinstall the boot sector, which is not a file, but the bit at the very beginning of the disk which tells the system how to boot. You will, at minimum, need to restore the boot loader (ie MBR). You did not advise an OS, so its difficult to provide more accurate information, but you should be able to Google "install bootloader [OS]" in Google to get the answer on how to do this for your OS.
