After doing many disk repair functions (and all the time it says the hard disk is OK) and some NVRAM resets, I was able to get into recovery mode and did a format for the Drive "Macintosh HD" just below Toshiba xxxx and then I headed to the main menu and chose to install el capitan directly from the internet (I could not risk getting back to my usb bootable installer) and from there during the download while watching the log move endlessly, the screen went off, completely and the fans went running again...
If I open the computer now, the grey loading bar comes, and then at 70 percent goes away to give me a no entry sign against a grey screen..
I am pretty sure there is something wrong with the app, its not just hardware because I checked my drive..
Now I cant even access single user mode, because it goes corrupt at the end now (check the image below)
I dont think we have official Apple shops here where I live, we only have resellers and some may have a support and maintenance team. But the way I know it, there is little or no skill or craftsmanship in whatever field or industry here, people here tend to break things more than they fix them, a very unfortunate reality..
Is there a way I can download the last el capitan from somewhere other than the app store? because every time I download it from there something fishy happens, like the file starts halfways (not from zero) and fails to download several times,.. I have a strong feeling this happens because of that file I have, its just mutated or something..
Is there anything I can do on my own from here, before I surrender my machine to strangers who might not know what they are doing??
