[QUOTE="42liberty, post: 1327998, member: 224070"] The main issues is a snow leopard install disk that is stuck in a recently erased (zero'd out) leopard iMac, it keeps booting from the cd and I can't eject it. [SIZE="2"]Here's my situation:[/SIZE] I work for a college and we bought 2 new iMac's with Lion, for a total of 4 iMacs. 1 iMac Leopard 10.5.4 1 iMac Leopard 10.5.8 I have an iMac at home running Snow Leopard 10.6.2 updated to 6.8 I only have 2 installation disk sets: 10.5.4 & my own 10.6.2 disks The other 10.5.8 disks seemed to be lost by the person working here before me. All the students work is backed up but I don't use time machine. I have 2 external hard drives with plenty of free space. But I think for this problem I may have to use time machine for the first time, but I've already told time machine not to use these 2 external drives. There's also a MacBook running Snow Leopard 6.8, no problems there, just want to upgrade to Lion [SIZE="2"]Here's what I wanted to do:[/SIZE] Update everything to Lion, including my personal computer I know you need Snow Leopard to jump to Lion But I would settle for at least getting the 2 work iMacs updated to Snow Leopard Or even less, I would be happy with just reformatting with them Leopard so they're clean for the next semester, but I'm missing 1 set of install disks, 10.5.8. So I'm only focused on fixing the 2 iMacs running Leopard. [SIZE="2"]Here's what happened: [/SIZE] So I tried my Snow leopard disks and they didn't work [I]"Mac OS X can't be installed on this computer"[/I] I tried my 10.5.4 disks on the 10.5.8 iMac, and it didn't work The 10.5.4 disk not working on a higher version makes sense to me, but why can't I upgrade from Leopard to Snow Leopard with the cd Without the 10.5.8 disks I decided to leave that machine alone, before I did more harm then good. So now I'm only working on the 10.5.4 iMac because I have the original install disks. I used disk utility during another failed snow leopard install. I erased not only the "macintosh" partition but also the entire hard drive. I also zero'd out all the data in an attempt to get snow leopard to work. At this point the snow leopard disk is in the machine and I restarted it hoping that Snow Leopard would install but nope [I]"Mac OS X can't be installed on this computer"[/I]. [SIZE="2"]Here's the problems:[/SIZE] 1) Why won't a snow leopard disk work on a leopard machine even after I formatted the drive? If I could install snow leopard using the disk that is stuck in the machine then it would just eject itself during the intsall, problem solved. 2)How do I eject a disk that is being used as a boot disk? The snow leopard install cd stuck in the zero'd out leopard iMac, if I could get the cd to eject then I could reinstall leopard and forget about this mess. 3) Could I use time machine to back up the 10.5.8 iMac and use that as a start up/back up disk for the zero'd out 10.5.4? Because if that was the case then I would be able to get the snow leopard disk out, I hope. 4) Do I have to format one of my hard drives so that I can use it as a time machine and does it still work as a normal external hard drive. I keep one of my back up drives formatted as a windows drive because a lot of my students use windows laptops. I run MacFUSE & Tuxera NTFS on all my Macs. Any help would be greatly appreciated! I'm new to this forum, but I'm looking forward to being a part of this community and hopefully one day I'll be able to help someone else out. [/QUOTE]
