I accidently erased VOLUME GROUP instead of just the Mac HD- Data, so what do I do?

I have a Mac 21 inch with an HD drive . Since I deleted the volume group , so I don’t know what to do next . Shall I put it on Internet recovery , will I get my data still ? Can you help me with the software . My main thing is the photos about 300 gb of photos . Are the software’s free ? Can you suggest me a step by step procedure ?

TimeMachine is designed to run all day in the background even during heavy activity with little impact on your work. If a file is busy during one attempt to backup, it will eventually be available for backup.

I was working on Catalina . I

sont have a back up . Plus I deleted volume groups . Can I still recover data .... and what is the procedure , what I can see after I press alt key , is on end drive and below it a network to choose from , after I choose the network I see only a suitcase with a question mark ?

my loss is the data loss of my pictures , my I cloud couldn’t back up as many puctures , there are about 59,000 picture and videos & iCloud has only 35,000 . PLWASE HELP REQIRED URGENTLY . Thanks

Hmm . That’s a sad state I am in . Will it give me good hope if I say I don’t have an ssd, but an HD . And can I do it at home after I buy a software ? And what’s the process now , such that I don’t over write and delete my HD ?

plus , can you explain what aise external Mac OS drive ?? Plus if I need to erase the whole external drive , so which external drive are we talking about ? And since the whole globe is in lockdown , can I do it at home ??

You do not mention where you are. In the US, OWC (macsales.com) sells external enclosures and external-open-connectors (plugs that do not encase the drive bust just attach to). They sell good drives as well. Other countries have access to other online sources. While I do not usually recommend all-in-ones from Western-Digital because of long-term reliability, anything that connects to a data port is usable. Best Buy (in the US), OWC, other online providers still send to you.

As long as you have available ports, you can connect several external drives.

But that is if you do it yourself instead of sending the drive to a service provider.

i have the same problem i couldn't install the mac os because there isn't a hard disc to pick.

i don't have the view tab nor the option to view all devices..

all i have is apple hdd media and os c base system

I did this too. But not when I go to reinstall Catalina, at 3 minutes remaining, it says, "Could not create a preboot volume for APFS install." Anyone have any suggestions? Thanks in Advance.

Thanks. I did that too. I shut it off and then did CMD R again and it instantly went to starting recovery from the internet?

I can confirm HerrNobel’s detailed steps saved the day for me. Thank you so much.

Thankyou so much! I did try this once and it didn’t work but did a restart and then it worked ❤️ Saved me.

thank you! it worked

You're welcome.

my dialogue box doesn’t have a “view all” option 😭

Yeah, I fumbled through it. I had to delete the _data volume, delete the contents of the Macintosh hard drive, leave the options at default settings (the options on the online articles don't match what I was seeing) and restart a time or two. I really wanted to use Catalina but there doesn't seem to be a way if I want to keep it ready for a new user to do the initial setup. It either makes a redundant _data volume or complains that it's not a complete drive if you remove the data volume.

Were you ever able to fix this?
