MacBook Pro :: Can't Boot From Snow Leopard DVD?
Sep 5, 2010
I need your help diagnosing this early 2007 Macbook Pro running the latest version of Snow Leopard. It isn't mine, rather my sister's, so I don't know the full details of everything as I don't see her all the time. Last December, I swapped in my 160gb 5400RPM SATA drive from my late 2006 MBP into her MBP as I had just bought and installed a 500gb 7200RPM drive into my MBP. I installed a fresh copy of Snow Leopard onto her machine, patched it up, and sent her on her way.
A few weeks ago, she came to me saying she was having trouble booting into OS X and was just having trouble using her laptop in general. The hard drive wasn't making any erratic noises, so I figured the system install had corrupted itself. The problem was I wasn't able to boot to the Snow Leopard DVD. The DVD would show up at boot when holding down the Option key to show boot devices, but when clicked, it would show the Apple logo, then the "prohibitory" symbol and the fans would spin up on full blast, with no further progress.
Booting into Single User mode, I was able to run disk repair and after running it over a few times, I was told the drive was without errors, the laptop booted fine (minus the booting to Snow Leopard DVD) and I gave the MBP back to her.
Fast forward to today, she's having issues booting in to OS X again. It'll show the Apple boot logo, but the small spinning circle will freeze, and the whole laptop will come to a halt. I still can't boot to the DVD either, with the same symptoms as above. I'm sure I can boot into Single User mode, run Disk Repair, and probably be good, but I want to attack this issue at the source.
Is the hard drive I've got in her MBP going bad (I can't hear any of the erratic noises you hear when you know a drive is going bad)? What else could it be? What about the inability to boot to the Snow Leopard DVD? What is the problem and how can I fix it? Thanks, and sorry for the long winded post.

I want to reformat my hdd and split it on few partitions but i get following problems
- Disk utility doesn't allow to split it, i check it in single user mode, nothing works
- Doesn't want to boot, I tried to boot it from external hdd, usb, cd, dvd, nothing works, I just see Grey apple and that's it,nothing happends
I left it even like that for whole night and nothing happened..I did scan disk, check blocks etc. no errors :/ it give me some filesystem error (which i googled and it sayd you need to boot from different partition so it will work) c, cmd r, doesnt work..starting with opt key gives me list of devices but it freezes after My macbook pro is from mid 2010, 8 gb of ram (i did change it by myself, but works perfectly)The os snow leopard works perfectly, but I need to split the partition..Tried to reinstall os but it stops after restart (in middle of instalation) , it gives me grey apple and thats it.I don't have original dvd, lost it some time ago, can't get new one since I moved to middle of nowhere(no apple shops or anything)single user mode commands would be most helpful, id just format the hdd and split/reinstall the os from zero..Is there any chance to reformat/partition hdd from single user mode? or any software that I can boot from ?

I was planning to get Snowey and a SSD at the same time, but the latter had to wait. So far, I�m seeing at least a ten seconds improvement in boot time with Snow Leopard:
17" Macbook pro unibody 2.93 Ghz, 4 GB ram 7200rpm HD
before SL: boot up from 39 to 55 seconds
after SL: boot up time from 30 to 39 seconds
Ok, so there is no interest in this topic.
For me boot time is a rather important criterium.
And I think the fact that SL reduce this with almost 10 seconds is AMAZING.

It just hangs at the spinning pinwheel. I shut the machine off and booted it into Verbose-mode (Command-V) and it stops at "Initializing Power Manager" or something very early on. I pulled the battery and unplugged the machine, am letting it cool off (not that there's a point) -- it's one of the original MacBooks that had that "shutoff" problem with the wire that'd melt and short to the heatsink but mine never had the issue because I wasn't using it very often at the time. Any ideas? The drive does show up when I hold down Option.

I have been trying to boot into 64-bit kernel in Snow Leopard on my Late 2008 Aluminum MacBook (2.4 GHz), but it is not working. It is running the 64-bit EFI firmware and is updated to 10.6.1.

My leopard installation was giving me a lot of headache so I thought of doing a clean install. Now that Snow Leopard had been out for quite sometime and many issues solved; I thought of installing it instead of Leopard. All I did was follow the instructions to install Snow Leopard [the only option with Snow Leopard was that it did an "Archive and Install" kind of thing by default]. It did take a lot of time [1 hour?] and I was finally taken to my desktop. I looked to check if everything was okay. Though there was nothing spectacular about Snow Leopard. I shut the computer down. Today morning I get this and I can't boot.

After dropping my macbook I had a black screen with just a cursor that would move though could not perform any actions. After reseting pram and smc, i now get to the screen with the stars and what looks like the aurora borealis or whatever. The cursor is there though nothing is happening when trying to click and when i press any keys, i gent that *dunt* noise indicating i have tried an invalid action. Does anyone know what might be the problem? I m hoping i wont need a new hd or mobo. This is my first time on the apple forums.

I couldn't find my problem between discussed Issues in the forum.
when i insert my DVD into my ROM, i doesn't boot from it, and it ejects automatically, i can boot other OS, Like WIndows or Linux, if i take to service somewhere it costs alot, the boot page (White page, by holding "Alt Option Key") doesn't recognize the DVD, and it does other OS DVDs.

I have a Macbook Pro 17" with 10.6.8 installed but won't bootup. It stays on the logo and spinning gear screen and won't proceed from there. I have tried to reboot from a Snow Leopard install disk but it won't recognize it and haven't been able to startup from another computer using firewire connection.

I got a used MacBook Pro 2.53 GHz 17" (Mid-2010 - MC024LL/A - MacBookPro6,1 - A1297) running Lion only.Â
I want to put Snow Leopard on one of the partitions, because I still need to use Rosetta from time to time. The computer didn't come with any installer disks... "no problem," I thought, because I own a Snow Leopard installer DVD (which says "Version 10.6" on it).Â
But it won't boot from that DVD.  The Apple logo stayed on the screen for seven minutes before I gave up.Â
Is that because this computer requires a later version of Snow Leopard?Â
What are my options for getting Snow Leopard onto this thing?Â

I have a MacBook 13" 2.0 GHz with 1 GB Ram and a 80GB harddrive 2006 model. This machine recognizes all ram, DVD, Hard Drive and ng usb etc. seems to work perfectly. BUT, it will only startup if I HOLD the PowerButton down all the way down until I see the the Apple Logo. If I just hit the powerbutton and go, it will t reboot over and over and over. I have bought new ram, nope. I tried a different HD, nope. I disconnected the DVD, nope. It simply won't boot properly. Once I HOLD down the power button to get it running it works fine, sees the camera, BT, WIFI, clock is at right time, all keys on KB work, and usb peripherials. I cannot reset the pram or vram at all, even while holding the power button down to boot. If I just hit the button and quickly press Command option p r it just reboots like always. Does anyone have any ideas??? I'm at a loss as it works fine once booted. While holding the power button to boot it I see my front led flashing and then hear the several beeps and it starts up just fine.
I have pulled the battery, removed the PSU, held the power button for a whole minute battery or power and let it sit overnight like this but nada, still does this.

All I get is the grey screen and the little circle with the rotating fan blades. Then they stop spinning and it just hangs.
I cannot boot up. Is this a bad hard drive? Â Are there other keys I could hit to make something work?

My hard drive recently crashed. I just bought a new one and installed it myself. Now it's simply a matter of reinstalling the operating system, which is where I'm having trouble. I insert the Snow Leopard Install DVD into the drive. I power on the computer and hold 'C' (I've tried Option too) to boot from the disc, but it doesn't work. It spits out the disc after a few seconds, whether I hold 'C' or not, and then it gives me a folder icon with a question mark in it in the center of the screen, the same thing it showed when my hard drive first crashed.

I was just about to order Snow Leopard, but then it hit me. Could it screw up rEFIt and my triple booting-ness? I asked my friend who is also using rEFIt and they think it could mess things up. What's your opinion, will it do no harm, or will it? And if it does, should I still get Snow Leopard? It was a bit of a pain installing everything, and I've just finished installing 80GB of games onto my Windows partition, so obviously I don't want that getting wiped or unable to boot!

I bought a Mac OSX 10.6.3 Snow Leopard CD (Family Pack) to upgrade on my Macbook Pro, but it won't boot. There are sound like it was running but it reject in the end. My Macbook Pro is Intel Core Duo 2GHz with 2GB Ram. It is currently running OSX 10.5.8. I tried the disc on other Macbook running 10.6.6 purchased 2-3 years ago and it work. So I don't really know what happen with mine. My DVD drive work fine though.

I have a tower Mac Pro with Snow Leopard running on it.Unfortunately one of the software that I use doesn't have yet a Snow Leopard update. So I am thinking maybe I can install older version of Leopard on one of the internal drives (i have 3 additional internal drives), so I can boot my computer from either Leopard or Snow Leopard, depending on needs (i don't want to get rid of Snow Leopard).
I never installed OS X system before, so I am a bit scared.The internal drive is ready, I have the old Leopard on disks, what are the next steps to take?

I've seen something about com.apple.boot.plist, but I need a little more further information. After type: Code:
ioreg -p IODeviceTree -w0 -l | grep firmware-abi
I receive the following from terminal:
Code:
|| "firmware-abi" = <"EFI64">
Looks that I am able to run 64-bit kernel.

Brought snow Leopard from Apple, and got it yesterday. I installed it today, and whilst it seems faster I have a few problems. Mainly that it doesn't seem to boot into 64-bit mode, neither from an app changing it to boot into 64 bit or by pressing the 6 and 4 keys down.
Also, does anyone know why a plugin to make Quicklook have a list view for Folders won't work anymore?

I set up windows xp on my imac using boot camp and then used the snow leopard disc to install drivers etc. I then tried to install a game (GTA IV) but setup.exe immediately crashed to desktop. I tried with another game (Fallout 3), same thing. Today I tried re-installing xp without installing the drivers etc from the snow leopard disc. This time, both games installed fine. But without the extras from the snow leopard disc, I can't play them.

I ran the 'Software Update' on her machine and it had several (6+) updates including the updates for the EFI bootloader; I clicked 'Okay' to reboot and apply the updates and after the 'chime' the machine hangs in the 'grey-screen' with the Apple logo and a progress indicator. After a period of a few minutes it appears the machine turns itself off (or at least the screen goes dark)
[code]...
Also understand that my wife doesn't have Applejack, DiskWarrior, or any other type of utilities installed, *sigh* nor does she know where her installation disks are... so I think I may be at a loss until I can get the machine to the local Applestore and schedule a time?
