Sorry about forgetting to post back. I did the whole procedure on the PC again and it turns out I skipped a step so it all worked eventually. Thanks again for all the help. I feel like my youth playing with LEGO Technics has somehow contributed for my success, but this site was wonderful in all its simplicity!
I used a PC to make the usb drive. Downloaded the installer from the App Store and then transferred it to a pic where I extracted the .dmg file from the installer. I used a programme called transmac. I will see if it is possible to make the usb on another Mac. I know the whole process of making the usb drive on a pc was a detour but I didn't really have any other options... Thanks anyway for the help. I'll post back with progress.
That's what I do though. With all the other key combinations I end up with a blinking folder icon with a question mark. i have tried the vpram reset as well so the problem isn't my keyboard. Could it be the usb itself? Or some other problem? If I did something wrong during the hdd replacement I figure I wouldn't have gotten this far, no?
Hi, I made a USB bootable drive with el capitan on it. Everything worked fine. I replaced my old hdd with the guide from this site. My iMac is from 2007. But now when I try to boot my computer with the Usb drive while holding the option key I only get a grey screen with a cursor. Any ideas?
