MacBook air stuck on grey screen/apple logo/loading wheel

[Tagnco]

Hi-
I'm new to Macs- just purchased this 13" Air off of eBay in March. It's been running great. Today when I started it up, it wouldn't go past the grey screen, apple logo/ spinning loading wheel.
I went to apple's website and tried the different troubleshooting tips and also removed the battery, etc. Still the same.
I looked through the posts here and am in the process of trying the Safe Mode boot. At the end of the Fsck -fy it says:
** The volume Macintosh HD could not be repaired after 3 attempts.
*****FILE SYSTEM WAS MODIFIED*****

Any suggestions?
Thanks.

Now it's backto the grey screen/logo/wheel thing "/

Edit: I typed reboot
Now I am getting a bar below the wheel which is loading as I type...

Try those steps. If those don't help and you're still inside warranty, take it to Apple.

Thank you for the reply

Just an update: I did the Fsck -fy again and very quickly it checked an said the Macintosh HD was good.
So I'm rebooting, but have the same grey screen.

I'm going to follow the steps in your post's link.
Thanks again.

I would skip the hassle and just take it to the Apple Store. Either they tell you that the OS installation got corrupted and needs to be reinstalled (which you can do yourself) or the SSD is busted and needs to be replaced.

I suppose I will have to take it in bc I didn't receive any reinstall CDs with the Mac.
