A few quick questions that I hope someone with a little more experience can help with. Well I booted up my Macbook this morning after a crash last night, and a folder qith a question mark icon appeared. After doing some research and attempting to run disk utility, it appears my harddrive has unfortunately died, as it refuses to show up even after a PRAM reset . I dont have a back up of the drive, and really dont want to lose the stuff on it. As I have an external drive, I was wondering if its possible to install OS X this, and boot from there? Ive tried inserting the install disc, however the installer tells me ''You cannot install mac OS X on this volume. Mac OS X cannot start up from this volume", along with a red exclamation mark next to the drive icon. If its not possible to install, is there anything else I can try? Or is it a case of accepting the loss (sniff sniff) and moving on? Im pretty sure its still under warranty, which is something at least. However, Ive upgraded to 2GB ram, and im not sure whether I have the original sticks to replace. Would I lose this if it was sent back to apple for repair/replacement. Thanks in advance guys, hope this isnt too unclear/messy. If i need to clarify something, just let me know! I realise theres a lot of questions here, but hopefully someone will be able to help me out with at least some of them.
