How to recover accidentally deleted startup disk on Mac?

Hi everyone, I need urgent help! I accidentally deleted my startup disk on my Mac while trying to clear some space. Now my Mac won’t boot up. Has anyone faced this issue before? What can I do to recover the startup disk and get my Mac working again? Any advice or step-by-step guide would be greatly appreciated. Thanks in advance!

Oh no, sounds like you’re in a tricky spot. Don’t worry, it is possible to recover your startup disk. Let’s start with a few steps you can follow.

First, you need to enter Recovery Mode:

  1. Shut down your Mac completely.
  2. Turn it back on and immediately hold down Command (⌘) + R. Keep holding these keys until you see the Apple logo or a spinning globe. This will boot you into the macOS Recovery Mode.

Once you’re in Recovery Mode, use Disk Utility to check if the disk is still there:

  1. Select Disk Utility and click Continue.
  2. Locate your startup disk in the Disk Utility sidebar.
  3. If the startup disk appears there but is grayed out, select it and click Mount to see if you can access it.

If you can’t see the startup disk or it’s corrupted, you might need more advanced recovery tools. One option is Disk Drill, a powerful data recovery software that works on Mac. Here’s what to do:

  1. Download Disk Drill for Mac users here: Disk Drill. Since your system won’t boot, you can use another Mac or create a bootable USB drive with Disk Drill installed on it.
  2. Follow Disk Drill’s instructions to create a recovery drive.
  3. Plug the recovery drive into your Mac and boot into Recovery Mode again.
  4. Run Disk Drill from the recovery drive. Disk Drill can scan your startup disk for lost data and may help you recover it.

If this doesn’t work, you might need to reinstall macOS:

  1. In Recovery Mode, choose the Reinstall macOS option and follow the prompts.
  2. Make sure you’re connected to the internet as this process will download the necessary files from Apple’s servers.

After reinstalling macOS, you can restore your data from a backup if you have one. Use Time Machine if you’ve been backing up your system regularly.

Hope that helps! Let us know how it goes or if you have any questions along the way.

Have you really deleted the entire startup disk or just the files? If you’ve wiped the whole thing, reinstalling macOS seems like your only shot. Boot into Recovery Mode (Cmd+R during startup), use Disk Utility to see if you can reformat and reinstall macOS. If that doesn’t work, you might want to look into data recovery software like Disk Drill for Mac. It’s not perfect – it can be slow and doesn’t guarantee a full recovery – but it might help get some of your important files back.

Accidentally deleting the startup disk on a Mac is a serious, but not uncommon issue. Here are a few steps you can try:

  1. Recovery Mode: Boot into Recovery Mode. Restart your Mac and hold down Command (⌘) + R until the Apple logo appears. This gives you access to Disk Utility.

  2. Disk Utility: Once in Disk Utility, check if you can see the deleted startup volume and attempt to restore it. If you can’t find it, try to reinstall macOS from the Recovery Mode.

  3. Reinstall macOS: In the macOS Utilities window, choose ‘Reinstall macOS’. This should not affect your data, but since your startup disk is deleted, it’s worth trying.

  4. Data Recovery Software: If you’re worried about data loss, consider using a tool like Disk Drill. It has saved many in similar situations. You can check an Independent Disk Drill Review to see if it fits your needs. This might help in recovering files before you attempt any further steps.

  5. External Boot Drive: If nothing works, use another Mac to create a bootable external drive. Then, boot your affected Mac from this external drive and attempt to recover or reinstall the OS.

Oh man, I’ve been there and it sucks. First off, yes, it’s a huge mess when you delete the startup disk. Try booting into macOS Recovery Mode (Cmd + R during startup). If you have a Time Machine backup, you could restore from there. But if you don’t? You might be SOL. Tools like Disk Drill can help, but honestly, I’ve had issues with it being unreliable and slow as heck. Your best shot might be Apple Support or a local repair shop. Good luck, dude!
