Hi all, I'm a long time Windows user but Mac noob through and through. My wife's MacBook stopped working properly ages ago so we chalked it up to a mobo issue at the time. Recently I dusted it off and the system turns on properly when plugged in; I think it's just a loose battery connector. Anyways, the bigger issue is one I created. I wanted to revive the laptop with an OS that's newer/better supported than 10.5.8 without having to buy something new. So I performed a time machine backup, but also wanted to manually back up her files in case we jump to a different OS such as Windows or a Linux distro. I read a few posts about this and was lead to believe that I could simply cut/copy and paste the files/folder structure onto external media. I went ahead with this -- I cut and paste, which is where the mistake began. Everything moved over without any warnings. From here, I planned on installing a new OS (Linux Mint at the time). When I rebooted the machine, I realized the error of my ways. I got the dreaded question mark box. I suspect I ruined the OS as well as the HDD bootloader. It gets better: I don't have an OSX recovery disk to fix up my mistake. I've been trying to fix this with other CDs -- Windows repair, Linux, the ultimate boot CD, hiren's boot CD. Nothing works. The closest I got to a fix was installing Windows 10, but it didn't see the HDD at all, nor could I repartition/reformat. I'm stuck. I imagine I need an OSX disc to get anywhere? Very frustrating. My dad found an OS 10.4 set of disks lying around, so one version down. He's shipping them up and I'm hoping I can recover using those. Anyone have any suggestions? If the OSX 10.4 discs won't help me, I'm hoping I'm missing something obvious. Thanks!
