Hello,

I deleted my ssd trying to solve an efi partition error.

I have a Macbook air 13 late 2010 that had Mac Os Sierra and wanted the High Sierra, but the efi partition wouldn’t mount neither through disk utility nor through terminal, so i tried formatting the drive but somehow i only ended up with os x base system, nothing else, the macintosh is now os x base system of 256 GB even though i only had 121 gb, now i cannot boot into recovery mode anymore, the bar in the loading screen fills up but nothing else happens, cant access internet recovery mode or the normal mode, the only one i can use is the single user mode, i tried mounting a bootable usb from there and even though it shows it is mounted, it wont appear at start up when i press Option key, i already reseted the nvram and smc nothing works, can someone please help me as i am about to lose my mind, i was that stupid to not create a back up. In single user mode when typing ls -l /dev/disk* the following appear: disk0, disk0s1(msdos) disk0s2 that cannot be mounted or anything

I cannot use anything besides single user mode, in start up manager only os x base system shows up and that doesn’t load, even if the bootable usb is connected and mounted it won’t show up as boot option

Do you have a secondary Mac? If so, you can put the MBA into Target Disk Mode and do everything from the secondary Mac operating on the MBA as if it were just an external SSD

If there's Thunderbolt passthrough, probably

Well i don’t how to add a thunderbolt passthrough,however, the laptop that runs windows has usb c, i dont know if it’s relevant but i’m trying to get my hands on a usb c cable to see if i can connect the mac as drive to the laptop, if this doesn’t work, what are my other options?I cannot afford a new one thus the endless struggle

Target Disk Mode only works over Thunderbolt or FireWire.
Thunderbolt passthrough means the host passes the direct signal to the VM.

Your other options are finding someone else who has a Mac. I can't really think of anything else with he described circumstances.

You should be able to use Internet recovery to get this going.

Try holding command-option-r (all three at once) at boot. Select your wifi then you should see a spinning globe while the recovery utility downloads. Once the recovery screen comes up format the internal drive with Disk Utility then reinstall the OS.

If you don't get the spinning grey globe, you are not in Internet recovery, and this won't work.

It doesn’t work, i know how to boot in internet recovery mode, but it won’t boot, it just loads forever, the only mode it accepted was single user

You are kind on in a tough spot here then. Can you access a friends Mac to make yourself a bootable USB key installer?

I'm wondering if you have some other underlying problem beyond the OS not being on the drive. What lead up to all this... symptoms?

Corrupt efi partition that wouldnt mount nor repair, and i followed apple cs advice but i might have did something wrong when erasing the drive and i ended up with just os x base system, when i press option key at booting, the base system appears and the option to connect to the internet but it still won’t do anything, i am trying to create a bootable sd card( the only one large enough i have) on Vmware from the windows operating laptop. So at the moment the macbook has no OS installed.

Glad you've got it working now. Really strange that Internet Recovery didn't work though.
