Try to fix a friends computer, the hard drive is failing on her HP envy m6 and I need to install windows 8.1 OS over to a new drive. The computer will not boot completely and it has bad sectors affecting the c: drive. Windows tries to fix them but it ran for over 24 hours and never finished. I have been able to copy over the recovery partition to a new drive, but an OS transfer using partition software does not work. Is there any way I can recover the OS to the new drive using just the recovery partition?
