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.
Here's my situation:
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
Here's what I wanted to do:
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.
Here's what happened:
So I tried my Snow leopard disks and they didn't work
"Mac OS X can't be installed on this computer"
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 "Mac OS X can't be installed on this computer"
Here's the problems:
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.
