Unable to install OS X or boot OX (rMBP A1398)
I changed keyboard from japanese to norwegian and the bottom cover. This went without complications.
When I booted with new hardware - just grey Apple screen and a spinning wheel that stopped. Trying to recover, internet recovery, single mode, securety mode or all other suggested boot methods fails. It will not boot or install OS X. Hardware test simple and extended shows no problem with memory (16bg) and the 500 gb ssd.
I have of course tried reseeting pvram..etc nvram
Using thunderbolt and another mac gives me access to the 500gb disk in my rMBP 15". I can even install Maverick using another MBP, but my rMBP will not boot even when OS X is correctly installed (boot the other MBP via thunderbold and my rMBP is OK).
I can install Windows 7 and 8 without any problems, but I need to have OS X installed. I used Mavericks and Windows 8.1 in bootcam earlier.
Linux rescue disk like Systemrescue boots correct and GPARTED can be used to partitionate the disk and formnat it as GUID disk. But trying to boot from a bootable USB or DVD using SuperDrive always stops after the Apple sign and spinning wheel stops.
Could it be the EFI bios settings? Is it poosible to update EFI without OS X installed? Any suggestions?
Es esta una buena pregunta?
