Go to solution Solved by Decon,

i have a macbook air and no CD, how do you create a bootable usb drive, i know how to do it for windows but Mac is a whole new world

any live USB all work fine; just create it like you were going to use it on a PC.  as for re-installing OS your best bet it buying a USB CD drive and using an OSX upgrade CD (assuming you have one)

try booting using USB media and transferring the files from there.  OSX also has an OS recovery mode on boot if you hold certain keys...

sounds like you may have bricked the UEFI; what is the internal storage like?  (M.2 SSD, Sata, HDD...)

 

the recovery mode doesnt work.

SSD SM128c

remove the drive from the laptop and plug it into your PC, laptop is basically bricked until you can get someone to repair the UEFI (sounds like you force quit/shut down when flashing a firmware update)   

 

Can you access safe mode on boot? (CMD + S hold after power on)

try holding CMD + S until the text appears and then let go.  If you get to a root terminal you laptop UEFI is not bricked AFAIK

i can access the terminal if thats what you mean

ok you just have a corrupted OS then not a bricked UEFI BIOS.  Try re-installing OSX from CD, but before you do that remove the drive and copy any data; re-installing can delete existing files.  You could also boot from a live linux USB and mount the HDD from there to view/copy data.  Hold alt on boot and select the live USB media
