Hello, I have an Acer Extensa 4620z, the hdd went out on it, i replaced it and tried installing xp on it cuz i dont have the vista
recovery disks but I get a "setup did not find any hard disks drives installed in your computer" message. I also tried windows 7 as well but I get a "no os found" message. My understanding is that this laptop was designed only for vista and not xp, so I'm thinking I need storage drivers for it. Any help with this would be greatly appreciated.
I know this is a couple of years late but I've just come across the same thing.
In the BIOS set the SATA type to IDE (not ACHI) - Hope this can help someone else.
