Maybe you didnt make the usb boot disk properly. the external drive only costs $79 why are you rushing into wanting to take the computer apart and replace its ssd module (at a cost of around 249 to 289) to fix yourself? without trying everything else?

Ive tried linux before on a pc (i think it was the backtrack linux) and by default it put lilo on my main hard disk boot sector and it screwed it and not the sd card that i told linux to install it to. why not at least try to ask the apple store to take care of you? if its a 2011 model like you say it is then it won't do any good to take the computer apart. If its a 2011 model then it gotta still be under warranty. If someone has better ideas I am looking forward to it too.

So, theese are my ideas to reflash the SSD, I hope I can make it without buying a new one. Is it technically possible? Will the system recognise that the SSD was put back? Will it damage the mainboard?

Are the pinouts in the same order as in SATA? Because in this case, I just need 2 connectors and a bunch of wire. Correct me if I am wrong, but the Air's SSD is a SATA, but a smaller one. If there is no reader to that, I can make it.Where can I finde such? I have been looking for it the whole day, but no reader has the same connection that apple does. In order to repair and reflash the SSD from an older backup image that I have, I need an external SSD reader, which I can connect to another computer.The system detects external USB flash drive, but it can't boot from that either. I believe it stuck in the boot process when there are two OS (OSX, SUSE) and no boot records. The laptop is unable to start, unable to run diagnorstics, unable to run boot select, nothing, it just shows the gray background with no apple logo on it, so does not even loads the OSX.

I have made a mistake using my Air, I deleted the boot record on the SSD.
