If it's under warranty, send it back for a new one. Otherwise, you can have it replaced. Yes your info is gone. You may be able to recover it, but at a cost up to 1K and then they still may not be able too. Same thing happened to me. I now keep an automatic backup at all times so I don't have to go through that again.
If you are computer savvy, you can replace it yourself for under 100.00 depending on what hard drive you want in your computer. Read your manual to see what specs your computer calls for, then get you a hard drive to meet those specs. It may also show you how to replace it, or you can do a search online and you could probably find out how. But again, this is for a techy. You could damage everything if you are not careful and don't read instructions. You will have to have another computer to format the drive bootable.
Otherwise, check and see if you can get the drive and bring it in to be replaced and tell them you will load your programs. You may save some cash. (Reference your manual).

When you start up your computer, hold down the option key. This will bring up the bootable devices menu. Depending on wether or not you have an Operating System installed, you should see either 1 or more icons. Click on the one with the CD icon that should be labeled "Snow Leopard". Once you have clicked on the icon, click the arrow beneath it and your Mac will boot off the OS CD.
do you have the install disk? if so insert and start with "c" key pressed, this should boot off the disk, select language then on the next screen along the top you will see utilities, select this, and in the menu select disk utility, when it opens select the start up drive (main hard drive) and select repair disk, if this goes ok then select repair permissions, these both take a longish time. if they will not work go through the install procedure selecting the archive and install option.
If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.
1. with the DVD in the laptop hold down the option button as the computer is starting this will bring you to a menu where you can your boot device.
2.With the laptop powered off again with the DVD in Press the powerbutton and hold down the "c" key this will boot directly to the DVD
***It sounds like you have your boot device in the system preferences set to your XP disk. You can fix this once you boot the mac partion by selecting System Preferences then selecting Startup Disk and choosing the disk you want to boot the drive with.
IF YOU FOUND MY SOLUTION HELPFUL PLEASE VOTE 4 THUMBS UP (anything less hurts our averages) Thank you and good luck!
Try this. Make sure your boot CD/DVD is in the drive and switch off the computer - hold down the power button until it goes off completely - it takes 7 to 10 seconds.
Then restart the mac but immediately press and hold the alt key (or option key - the one next to the key with the pretzel on it)
After a moment or two you should get a blue screen with the spinning pizza. After about another 10 seconds or so you should get an icon of your HD and an icon for the CD/DVD
If you only get the CD/DVD then your HD has a problem. If your get neither then you had best take it to a service centre as there is something more seriously wrong.
Assuming you get the CD/DVD icon click on it then press the big arrow that should also be there (NOT the bendy arrow - that means Go back)
The computer should then start up from the CD/DVD. Once you get the Install screen come up, go to the menu bar and find 'Disk Utility'.
This will take over and you can run the first aid routine IF the utility can actually see your HD. With luck it will and will sort it out. then quit the utility and restart the computer and see what happens.
If on the other hand you didn't get anywhere, or disk utility gave you a failure message, then you need some more aggressive software like DiskWarrior or Drive Genius. They are both very good at restoring misbehaving or non-mounting HDs.
On the more black side, Apple unfortunately managed to fit a batch of bad HDs to some macbooks. These were made by Seagate. They ran beautifully for about a year and then failed catastrophically. Apple replaced these drive without question but unfortunately the data on them was completely lost. One of my clients send their drive to Ontrack who returned it saying that no recovery was possible.
So be prepard for the worst.
Try to boot from the CD the computer shipped with.
Insert CD and restart the computer holding the "c" key Your computer should boot.
If so run disk utility from the cd and repair the disk as well as permissions. If this is successful your computer "should" be repaired. If it still has problems booting, Use your CD to perform a Archive and install which should keep all your personal settings and installed software intact.
the flashing ? mark means its not seeing any bootable device do you have the original OS disk from apple???? If you do you need to boot with them and test the hard drive to see if its functioning and or there is an OS issue.
