![]() ![]() Nothing is seemingly restoring the EFI and boot manager, and I don't understand what the hell is going on at this point. I have tried both 2g RAM modules individually - both boot fine in Ubuntu, and both test as good in Ubuntu and Mac hardware test mode. I have hard reset the NVRAM/PRAM even with the memory removed as instructed on some Apple troubleshooting pages. ![]() (Ubuntu live still works, and will still verify RAM and drive as good.) On reboot, I still can't boot to target install disk without RAM error beep code. (And I have recovery disks anyway what the hell, Apple.) I cannot actually install the OS from App Store because I don't have a working App Store account or Apple ID. I can recover, erase and rewrite the partition for OS X and write the tables out. Hardware test mode (Boot + D key) can check out and verify the RAM, no beep codes. ![]() Installing Ubuntu throws the same disk error and dump, even after just checking the drive and telling me it was fine. Meanwhile I can still boot to Ubuntu from USB and the RAM checks out just fine. ![]() Apple's support says this is a RAM error. The stand alone 10.6 show the apple and pinwheel, but then gives the BIOS beep code of three beeps separated by about 4-5 seconds, continuously. (Have let this ride for 30+ minutes, it's not an update.) Reboots to installation media now do nothing for two of the disks (original and the Air USB stick.) No activity pinwheel comes up at all, just the apple logo. Live session works fine, go to install, it forces UEFI boot mode (overriding and overwriting rEFIt and Bootcamp and wiping the whole drive - in theory.Įxcept it throws an error on installing to the drive and aborts back to Ubuntu live desktop session, and now everything is totally screwed up.Īfter this first "force UEFI" install option: I'm trying to use to set up Ubuntu Studio (17.10). rEFInd also works and allows boot device selection. (Original 10.6 DVDs, 10.6.3 standalone DVD, and a Macbook Air 10.6 USB key.)īootcamp works fine. Also, the OS installation media I have checks out. Hardware checks all came back clean, including RAM and HDD. The stock OS (10.6) was snappy and just fine, aside from the fact that it has sadly walled itself into its own garden where apparently I can't even get a modern browser installed or even a package manager, but I digress. ![]()
