My step dad has dropped his laptop round and asked if I could fix it. Basically it won't boot and gets stuck in a loop restarting every time it tries to load vista. He dosen't have a recovery dvd so i have been trying to install my old copy of vista on. However when trying to install vista the installation cant see the hard drive and therefore won't install.
My Acer Aspire 5535 has a Hitachi drive click here I had a similar problem with mine it also would not recognise the drive I managed to save data using Ubuntu live CD then the Hitachi tool to repair sector.
