MacBook Air 2011 release , OS recovery I formatted my hard disk in internet recovery (disk utility) but it had a partition so I can't boot into the main disk all I see is APPLE SSD HTA..e.t.c which is 60 gb   and I can't see the main partition in disk utility plus I have no startup disk. Terminal's sudo command is also not working, is there anything I can do to gain root and erase all partitions?..it is still in recovery mode
Used Internet Recovery ⌘ Command⌥ OptionR and it worked fine. If you're interested you can buy a Apple technician's disk and boot from it  or buy a new Mac or do something simpler like installing Deb on a Mac with a damaged boot partition.
