Q: Deleted Mac startupdisk accidentally

So I was having problems with my macbook pro and I came here to apple and chatted with a person from support. I tried what they said to do but instead of fixing my problem I now have an even worse problem.

 

I think that I accidentally deleted my startup disk.

 

I was in interent recovery mode and it had a toshiba disk and an untitled now both of them are gone and I only have disk0 and mac os x base system.

 

This would not be a problem if I were able to choose a way to restart my macbook (Which I can not because I have no startup disks to choose from) and I can not reinstall os x lion because once again I have no startup disk to choose from.

 

does anyone know how to fix this or has anyone had this happen to them as well? If so how did you fix it?

MacBook Pro

    This is a User-to-User forum. No Apple representatives read these forums, and none responds here unless your post goes unanswered for days. If you want official Apple support, you need to call them back and someone can help you pick up where you left off.

     

    It is really hard to delete your startup disk. Almost impossible to do by accident.

     

    "Mac OS X Base System" is an Installer image. If you can start from that, it may update your existing system and get you out of trouble.

    I've already talked to an apple support person (not on the forum, by contacting support and chatting online) and I am not able to to start from Mac os x base system, I can't choose from anything to start my macbook up with.

    What YEAR is your MacBook?

     

    after about 2011, Internet recovery may be available in its firmware. Older than that you would need to use a DVD or a thumb drive Installer or take it to the store to have them start the re-Install for you. You need an appointment, but there is generally no charge unless parts are needed.

    Do you have another Mac? you may be able to get your MacBook Pro going using another Mac.

    I am able to go into internet recovery mode but it will not let me install a new os x because I have no startup disks. I just recently tried to start my macbook pro up and it is now showing a flashing folder that has a question mark on it.

    You have no startup disks, or you have no disks at all?

     

    You can use recovery to run Disk Utility (Repair Disk) .Sometimes it will fix things up enough. if not, you may need a new Drive.

     

    If you need a new Drive, you may be better off with an external enclosure as well. Then you can Install on the new Drive in an external, boot from it, and use it to reduce anything you can from the old drive. Once it is working as well as its going to, THEN do the surgery to place the drive inside the chassis.
