Leopard install hangs at DVD reboot

I cannot upgrade from OSX Tiger to OSX Leopard on my G4 iMac. I insert the DVD and follow the prompts to do the installation, however when my iMac tries to boot from the installation DVD it just hangs at the grey screen showing the apple logo and sits there indefinitely ( in desperation I have left for over 3 hours!)
My iMac is a 17 inch 1.25 GHz G4 so is fully Leopard compatible. I have used the same (Family pack) media to upgrade my MacBook with no problems. I have tried removing all peripheral devices, including oem memory and still no joy.I have repaired all disk and permissions issues using the Tiger DVD and all firmware is fully up to date.
I am totally at a loss to as to what to do next. Any help would be gratefully received.
Happy New Year

go to apple support and type in" imac and leopard." There's some software or firmware updates you probably need to do.

Snow Leopard install hangs

I tried an upgrade on my iMac6.1 from Leopard OSX 10.5.8 to Snow Leopard 10.6.3 (DVD) and the installation hung. When I inserted the DVD and began the upgrade procedure, the installation appeared to progress normally. The Install Mac OS X screen came us and the progress bar continued for about 10 mins. However, the installation appeared to get stuck after the Install window had gone away and the background and the wait cursor remained on the screen - it got 'stuck' here for about 45 mins and I aborted the install with a reboot. I noticed there was a "Mac OS X Install Data" folder created on the Mac HD, so obviously the installation progressed a certain way. The reboot put me back to by 10.5.8 system without any noticable problems.
I have not been able to find a problem that was described quite like this one so some help would be appreciated. Also, when the system rebooted with the SL DVD in the drive, it of course wanted to proceed with the installation - I was a little leary as I do not want to loose my apps, configuration and data (data is backed-up).
Help?

Rebooting the computer with the SL disc or starting the install by just popping the disc in and clicking install results in the same thing. There are lots of possible explanations for what you experienced. It is possible that the computer gods deemed your day for a crash had arrived. It might be the installation disc is a little dirty. Your hard drive may be barely empty enough for the installation. It may not have actually stalled at all! During the beta period last summer Apple engineers tinkered with the progress bar and timer quite a bit but it still is only (very) roughly accurate.
If you can do so, I strongly recommend you back up your computer and then try installing the OS again.

Leopard Install Hangs because G4-MDD goes to sleep

Computer in question: Power Mac G4, MDD, Dual 867MHz.
Had Leopard running fine, though I remember having a similar issue when doing the original install. The main hard drive crashed (no question - terrible grinding noise). Replaced the hard drive, started Leopard install, selected a recovery from Time Capsule. Started off great, everything seemed fine. When I came back later, I noticed the screen was off (power management) - moved the mouse and it came alive, but I got the 'system busy candy spinner' (not sure what else to call it) and the progress bar had stopped moving.
Tried several more times, and I noticed each time the process seemed to be working fine until I forgot to move the mouse every so often, then once it slept there was no coming back.
I tried installing a bare minimum Leopard install (much faster than a Time Machine recovery) and set the Energy options to "never / never", but the Leopard install DVD seems to have its own settings, and there's no apparent way to change the energy settings after booting the install DVD (no Control Panel access).
Any ideas other than sitting at the workstation for hours, moving the mouse every 10 minutes?
As I said I remember having an issue during the regular Leopard install like this as well - but that was much shorter and easier to sit there moving the mouse while the install completed. The Leopard recovery from Time Capsule is estimating anywhere between 2-8 hours depending on when I look...

Well, I might've found a fix - booted the install DVD and after selecting a language I went to the Utilities menu, picked Terminal. From a terminal session I typed:
pmset -g
Which shows the current power management settings. I could see it was set to sleep the display, disk, and system after 10 minutes. Then I typed:
pmset -a sleep 0 disksleep 0 displaysleep 0 force
Which told it to change these three to NEVER sleep, and "force" makes the command activate the settings even if it can't write the settings to disk (which it can't on a DVD obviously!)
pmset -g
Then told me those three were set to 0 (zero) and I exited the terminal process and continued on with the Time Machine full system restore (also in the Utilities menu) and I think this will do it... I'll update this thread and let you know!

Leopard install hangs up

Around 3pm today, I inserted the Leopard OS X 10.5 disc and double-clicked "Install Mac OS X". In the following window I clicked "Restart" and now my computer has "hung up" with the colored spinning wheel and has not restarted. It's now been seven hours.
One possible issue is that the computer goes to sleep during this process. Will that stop the restart from proceeding? Is there a way for me to change the Energy Saver settings now that it has reached this point? If I simply shut down and restart my computer is there any danger that I might lose information or corrupt my hard drive (80GB internal). Also, I have a 500GB external FireWire drive connected to the computer. Should I remove the FireWire connection before proceeding with the Leopard installation?

If you never got to the DVD self-check stage, which occurs first, then nothing should have changed and your system should still be Tiger.
The system should have immediately proceeded with the 10 minute DVD self-check.
See if you can eject the DVD with the keyboard. If not turn it off and restart it and hold down the left mouse button or the touchpad bar.
Check the DVD very carefully for scratches or that thin oily film found on some disks. If it has that file, clean it with a damp soft cloth, wiping radially center out. Do not wipe in a circular motion!
You should then be able to boot into the safe mode by holding down the shift key. After the system boots, restart it back to normal. Since you got to the first part of the install already, simply reinsert the DVD and shut off the computer.
Restart holding down the "C" key and you should boot into the DVD from which you can continue the install.
Be sure that you have done the normal preparations first: use the Tiger DU to check/repair the HD and file permissions. Do this before rebooting the system if you have not already done so. These two operations are very important for a smooth install.

Macbook Leopard Install Hanging

Help,
I have bought a retail version of Leopard 10.5.1 but every time I try and install it it just hangs there for ever doing nothing. Am I doing something wrong? I have trawled the groups and cannot find anyone else who has the same problem.
I have erased the HD repartitioned it and i still get the same result. Here is the log file showing the point that it gets to everytime before it just hangs.
Any advice greatly appreciated.
Thanks

I did the erase zero out data using DU, and I still get stuck at "extracting", It has been mentioned to me that the optical drive may be getting to hot, but the same thing happens even if i do it from an image off the hdd.
I have used 3 different leopard retail disks so i cannot believe that all 3 are bad dvds.
Maybe it is a problem with the optical drive, maybe it is something to do with the hdd / firmware or systems management. Who knows. It seems that apple care have no idea either.
I can install windows XP on it for heavans sake!! It's ridiculous that an apple os product will not install on native apple hardware.
Like I said earlier I will never buy an Apple computer again based on this experience. Windows Vista people moan about that OS but as far as I can see its streets ahead. To think I was almost an apple convert
One bricked macbook for sale spares or repair buyer collects and glues back together!

Can't finish snow leopard install, hangs at apple logo?

Everytime I run my install it will get to 45 minutes and then be stuck at the apple logo with the spinning wheel. When I try to boot from the disk also this happens. I'm pretty sure my drive is working as it can read other discs. This is also the retail disc with the snow leopard, 10.6. Disc utility tells me everything is verified, and I have also run applejack. I'm currently at 10.5.8 on a late 2006 macbook a1181. Intel Core 2 Duo with 2 gb. I know my laptop can run this but I keep getting stuck at this screen.

Thanks for your help!
I will try my Tiger Install Disk (4x CDs) to see if they work. I am able to play / burn CDs and play DVDs fine so this problem sounds fishy. I will try to clean the lens as suggested. If its of any relevance, i cant boot into by Carbon Copy Clone on my external HD either! (its formatted in APM and everything!) over FireWire. Bhaaa...
Oh well, at best i will re-install Tiger and head off to my local Apple Store and see whats up...

2011 27" iMac cannot boot from a slow leopard install DVD

I just got a new iMac 27". It came with Lion preinstalled. I wanted to install Snow Leopard on the 2nd hard drive and it wont let me boot from the DVD or run the Snow Leopard install from the DVD when running under lion. When I try to boot from the DVD I get a kernel panic. I am also having problems with computer not waking from sleep. I think I should return this computer as defective. Anyone else have this kernel panic problem?

As stated, you can't use SL on the Mac, so the kernel panics should subside if you're not trying to boot from SL. However, there are plenty of other posts re. freezing/not waking after sleep.
So, if you do want to run SL, you could try to find one that still has SL installed (and you'd get the free upgrade to Lion) - there are quite a few refurbished units at the Apple Store. If you're within the 14 days and purchased it at an Apple store, you can return it and could order a refurb with SL (or find a new one at a reseller who bought up the left over stock). That's what I've usually done.

Windows 7 install hangs at "Windows is loading files ..." on MBA

I have been trying to install Windows 7 Ultimate but each time the install hangs at "Windows is loading files ..." on reboot. I am using a Windows install DVD using an external drive. When the install hangs, the DVD is not being accessed. I have tried several times and it leads to the same result. I have tried different partition sizes (20 GB - 50 GB), no luck.
Any help would be greatly appreciated.

Solution
I have a macmini bought in mid2011 with OS Lion on it. AS it doesnot come with an optical drive, I bought an LG DVD drive and used the windows 7 (64bit) installation DVD. It stopped at windows is loading files....
I tired couple of other options like using flash dirve but it dint work.
The I went to Apple's Genius Bar, and they put the installation dvd into their dvd drive (by Apple). Then the windows installed perfectly fine.
When asked they said it must be the problem of DVD and I found out that it actually is the cause. Apple products require dual layer optical drives but in general the optical drives we buy can only read single layer dvds. So I got to fix the problem by borrowing their dvd drive in genius bar and now i m good to go.....
Hope this helps

How to install Leopard from an external DVD reader?

Hi,
I've bought Leopard today. unfortunately, it's not yet installed on my PowerBook. As my SuperDrive is dead, I use now an external DVD (Lacie Portable DVD-RW), but it doesn't work. I can read the Leopard install DVD, but when it reboot, it reboot on my current installation.
I've tried the following during the boot sequence:
- alt pressed, but I can only see my main HDD
- c pressed, but I boot on my current installation
Can you tell me if it is possible to install Leopard from an external DVD, and how can I do that ?
Thanks in advance.
Regards,
Emmanuel Di Pretoro

Can you tell me if the same problem occur with a FireWire external DVD ?
It does not occur on your model of Mac.

Backlight shuts off when booted on Leopard Install DVD

Booting my macbook pro on the optical drive (by holding the "C" key at power up),with the Leopard install DVD causes the backlight on the display to shut off. Reboot with the OS on the hard disk (OS 10.4) and the display works fine. Playing with the screen brightness keys has no effect on the backlight when booted on the DVD. I also did a pmu reset (remove battery and hold the power button for 5 seconds) The display functions normally during regular use, It only happened when booted on the leopard install DVD. I was able to complete the install with a 2nd display connected to the dvi port and the display now works properly when booted under 10.5. Just wondering if anyone has seen this behavior or has an idea of the cause.

I have the same issue. Can some one please help? Thanks

Computer locks up, so I want to reinstall the OS. I had upgraded to Snow Leopard.
Tried to do an archive and install from the DVD that came with the computer, but that failed.
Tried to do an erase and install, but the install stops somewhere near the end, 13 minutes to go. Tried several times, same result.
Can't reboot from the install disk, it just ejects the disk and I get the flashing question mark.
Any suggestions will be appreciated.

I think my hard drive is toast. When I boot in single user mode, I get the following text:

Cannot boot from Leopard Install DVD

Now that I know I have to archive and install (based on a previous post), I'm trying to boot off of my Leopard Install DVD. I put it in the drive when starting up, hold down "C", and nothing happens. I end up booting from the hard drive and getting stuck again. I reboot the computer, try again, and again, nothing. Finally, I pressed "option" on boot-up, got the boot menu, the DVD appeared after a moment, and I clicked on it. I could hear the drive spin-up, then nothing happened. It went to the hard drive again and got stuck in its reboot loop.
The drive should be fine, as I've been using it for normal purposes lately (including ripping music off of my CDs yesterday). Is there any other reason that an OS X Leopard Install DVD wouldn't boot properly? Is it the DVD itself? Or might there be another reason?
Thank you,
Joel

If the MacBook Pro was released on or after October 26, 2007, it can't use the 10.5.0 retail installer.
If the MacBook Pro was released on or after November 15, 2007, it can't use the 10.5.1 retail installer.
If the MacBook Pro was released on or after June 30, 2008, it can't use the 10.5.4 retail installer.
If the MacBook Pro was released on or after January 2009, it can't use the 10.5.6 retail installer.
If the MacBook Pro was released before October 26, 2007, it must use the retail 10.5 installers to install 10.5.
Otherwise it can only use the installer discs which shipped with it to install 10.5.
* is the retail installer disc label, which in fine print will say the update version of 10.5 included with that disc.
If you are missing the discs that came with the machine, and you bought the machine from an authorized service center contact AppleCare for replacement discs at a nominal fee.
Otherwise contact the seller, who should have given you the discs when he sold you the machine.
The discs include iLife, and a hardware test that you can't otherwise get with the retail installer discs for Leopard alone. A bundled iLife/Leopard 10.5.6 exists today called the Mac Box Set.

Downgrade using Snow Leopard install DVD does not work on iMac 27"

I have an iMac 27" (SMC version 1.54f36) that I wish to downgrade. I bought a 5-user Snow Leopard license. Now I'm trying to re-install from the DVD, but the computer won't boot on the DVD.
If I run the installer from the desktop, the installation starts, but when the computer reboots, it gets stuck. No alterations is done on the system disk, so I can hold down the Alt key and choose to boot from the system disk and I'm still on 10.6.5. For the moment I cannot find the discs supplied with the iMac, but surely the SL install DVD should work?? I've used it once before to do a clean SL install (I believe the iMac I have came with Leopard).
The version on the SL install DVD is 10.6 (2Z691-6558-A)
The reason for downgrading is that my Pro Apps (DVDSP and FCP) got a bit shaky when I updated to 10.6.5.

If you have a 27" iMac, it had to ship with Snow Leopard installed. See Mac OS X versions (builds) included with Intel-based Macs to confirm this, & Don't install a version of Mac OS X earlier than what came with your Mac for why you should not try to downgrade to an earlier version.
If the version on your SL install DVD is 10.6, then it is an early version & will not work with your iMac. The current retail product version installs 10.6.4 & should work if your iMac is the "Late 2009" model. It probably will not work if your iMac is the "Mid 2010" model.
You need your grey system discs. They should be kept accessible wherever you use your iMac. If you have lost them, contact Apple about getting a replacement set.

Can't install Snow Leopard on MacBook Pro - DVD won't mount

I am unable to install Snow Leopard on my MacBook Pro as the DVD won't mount. This is an early 2008 vintage MacBook Pro, intel core duo...
I'm using a OS X Snow Leopard install DVD (family licensed). This DVD has been used to install 3 other Macs in my house without a problem (about a year ago), but cannot be used to upgrade my MBP. Actually, this disk mounted on the MBP exactly once - inserted with system up, the disk mounted. Upon running the installed (a year ago), the computer restarted but hung in boot. After getting the disk ejected and the computer restarted, the disk would never mount again. I've defered upgrade for a year but at this point need to upgrade my MBP at least to Snow Leopard and possibly Lion.
The problem doesn't seem to be with the DVD, since it continues to mount fine in other computers, and in fact a borrowed Snow Leopard DVD also will not mount on the MBP.
BUT ... the problem also does not seem to be with the optical drive in my computer, as it can read & mount the install/restore disks that came with the computer as well as other CDs and DVD ROMs. Only the Snow Leopard install DVDs fail to mount.
I've also tried mounting the 10.6 install DVD on my Mac Pro desktop, making it available over the network (ethernet) with DVD/CD sharing. I can mount the remote disk from my MBP that way, but when I launch the installer, the application launches (its own menus are displayed, I can quit from menu, for example) but does nothing -- no windows open, nothing.
I've also tried "Remote Install" (again with the DVD made available with the Remote Install MacOS X application on my desktop), but when I boot the MBP with option held down, the remote disk is not available as a startup disk.
Zapping the PRAM did not help.
Am off to the store to get an optical drive cleaning kit and a blank DVD big enough to burn a new disk image, but would appreciate any further ideas at this point....

Solution that worked: Copy the Install DVD to a USB flash drive and boot from that.

Is it possible to make a copy of the Leopard install DVD?

Is it possible to make a copy of the Leopard install DVD? If so, is there a special way this has to be done? I just found out that we needed to use the Leopard install DVD to recover a complete backup from Time Machine after a recent hard drive failure. We have the family pack of Leopard, so I would like to keep the original at home and send a copy when my daughter goes off to college in case she needs to recover again. Her machine was originally a Tiger MacBook, so those install disks will not work. If it is not possible to copy the DVD, is there a way to create a bootable utility to do a time machine recovery?

This half-solved my problem. I have had no problems creating a backup copy for my intel based computers, but non-intel based computers are problematic; a G5 powermac tower and a G4 Powerbook. Both with super drives for single density burning. Both have Leopard running, installed from an install disc purchased from Apple. However, neither will mount the copy, but intel based computers will. have burnt/burned with both toast 9 and Disc Utility. Discs won't mount and are "spit out" by the drive.
