Software :: Unable To Boot From CD / Reinstall Everything
Apr 29, 2008It's an iMac G5 on OS X v10.4
Here's the problem:
When booting up normally it goes to a screen with an apple in the middle, and then some kernal panic code comes up:
panic(cpu 0 caller 0x002E1904) unable to find driver for this platform: "PowerMac12,1"
That's the first line of the code.
Anyway, i want to simply format the whole system and start from scratch with the system disk supplied with the imac. However, when i put it into the machine and press C at start up, it goes to an apple screen and hangs on that apple screen and does nothing else.
I've tried pressing the alt key and going into the boot options and booting from the CD there. However, that goes to the apple screen, then a little ajax style loading thing comes up. That sits there for a while until the apple turns to a "stop" style sign. This continues to hang.
I've tried resetting the PRAM and NVRAM by holding the Command, Option, P, and R buttons. Holding theses makes the computer reboot a few times until i let go. Once thats done, nothing changes.
I've tried holding X while loading up, this just goes back to the panic code.
I've tried holding shift while loading up, this again just goes back to the panic code.
I've cleaned the system CD and it makes no difference.
Mac Mini :: Server Won't Boot After Reinstall
Mar 22, 2012I had to reinstall Snow Leopard Server on my Mac Mini Server. I did it via a firewire connection to my MBP. Everything runs fine when I boot in target disk mode from my MBP. Problem is when I disconnect the MBP and boot just mini it gives me an error message that says I need to restart the computer. I have the two 500gb drives on the mini configured in a raid array.

Oct 7, 2010My HDD is split to 3 partitions at the moment:

Is it possible to reinstall Mac OS X without formatting storage nor Windows partitions?
Mac Pro :: Reinstall Boot Drive - Backup From Time Machine?
Oct 25, 2010I got the fatal folder with with question mark and grinding sound of the hard drive when starting my 2008 Mac Pro this weekend. After some diagnostics it was obvious the Hard Drive is dead, of course its the main drive that runs the OS and all my apps. I am picking up a new drive today and was wondering the best approach to get it up and running again. Everying it is backed-up on my external drive through Time Machine. Since the drive is dead I can't use a copy cloner to the new drive. Would I install the the hardrive and start the Mac Pro to boot off the Leopard CD, intall that and then try to run the backup from Time Machine?

View 7 Replies View RelatedOS X :: Cannot Reinstall The Snow Leopard Nor Install Windows With Boot Camp
Feb 13, 2010I've been having big problems trying to solve my problem. I've checked all the posts related, tried all the solutions and still I didn't get anything, so I'm sharing my problem and hope for someone to have the solution.
I installed Windows XP with BootCamp and it was working fine.
But then the HD space of the windows partition was too small and I needed more space. So what I did was erase the partition with the Disc Utility.
But before that I wanted to test the Parallels to see if the windows 7 would work fine with it. It installed easily but I didn't like the performance of it, so I just erased it with the AppCleaner. Then I erased the BootCamp partition with Disc Utility.
But when I tried to use the Boot Camp Assistant again, it only gave me the message: "The Disk Cannot Be Partitioned Because Some Files Cannot Be Moved"I've checked the forums and it was said that probably if I use iDefrag, it would solve my problem.Once I did it, I still got the same message.Then I decided to repair the dic, so I did the verification and clicked on Repair Disc Permitions and I've got this message:
-The file SUID "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" was modified and cannot be repaired.
Then I decided to reboot the whole system inserting the installation disc and pressing the C button, but all I get is a white screen and no response. And sometimes the Macbook not even start properly (also having only the white screen and no response), so I need to press the Option button till the Mac HD icon appears and I can access the computer.
And now I really without any option and I wanted to install the windows.
Software :: Boot / Reinstall System From External Hard Drive
Aug 16, 2010I'm selling my old Powerbook G4. Before I let it go, I want to wipe the hard drive and reinstall OS 10.4. I also would like to run disk first aid because I suspect there may be some corruption. The problem: I still have the original system install DVDs that came with the laptop, but the DVD drive no longer works. It just spins the disks for a bit then spits them back out. I do have an external USB hard drive with plenty of free space. Is there a way I can copy the install DVDs (there's a Disc 1 and Disc 2) to the external hard drive, then boot from that drive and treat it like I'm installing from the DVDs? I also have my new MacBook Pro with a working DVD drive. Can I make my Powerbook boot from a CD in the MacBook's drive? If not, how else can I wipe my system and reinstall the OS without a working DVD drive?
View 3 Replies View RelatedIMac :: Strange I5 - Reinstall Snow Leopard - Utilize Boot Camp
Dec 16, 2009I had a 2008 24 inch imac (3.06ghz C2D) and had some issues with it. First the hard drive failed, upon bringing it into the Apple store, they told me that they replaced the hard drive and screen (due to dust under it), however, this was not the case. What they had actually done is replace the entire unit and gave me a refurb which was previously registered to someone else (as evidenced by the registration info). A few months later, I had another issue, this time the logic board had failed and I once again had to lug this 20 pound beast through the largest mall in the city in order to get it to the Apple store (for the second time). I politely explained my discontent with this whole process, they did not inform me that the unit was a refurb and now it had failed yet again. Much to my surprise they offered me a replacement in the form of the i5 with a 1tb drive, 4 gigs of ram, the works. Now here is the problem: I was not given any of the included dvds as they do a "like-for-like" swap only. This is now an issue because I can not install Snow Leopard from the retail dvd, nor can I install Leopard from my previous iMac disks. In addition to this, I do not have the correct drivers for a boot camp install. Thus I am stuck if I ever need to reinstall Snow Leopard or if I need to utilize boot camp (which I do).

Mac Pro :: Unable To Boot / Kernel Panic At Boot And Graphics Card Failure
Mar 9, 2008Yesterday my screen (30" Apple Cinema) started showing symptoms of graphics card failure, jagged lines across the screen. I rebooted my Mac Pro and it was gone. Then it happened again an hour later, this time the machine didn't boot, I get the Apple logo, and then it hangs up and the screen is shifted to left (I get apple logo on left side of the monitor instead of the middle) and jagged lines all over.
So the first thing I tested was using Target Disk Mode, it works. I can access my Mac Pro's internal HD's by TDM from my MacBook Pro. Then I tested single user mode, it does boot, I can't read what's written since the screen is shifted to left, but if I type (without seeing) reboot and hit enter, it reboots. So I assume the single user mode is working.
What else can I try to 100% make sure it's my graphics card that failed and everything else is ok with Mac Pro? I already ordered a graphics card replacement but I wouldn't like to be surprised if the Mac Pro still doesn't boot when the card arrives. It won't boot from Apple Startup DVD either. Same thing happens, gray logo then kernel panic with jagged lines all across the shifted screen.
IMac :: 27" Wont's Boot Up / Takes A Very Long Time To Boot?
May 15, 2010I have a 2 week old iMac 27", i7, 2tb Hard Drive, 16gb RM
In the second week the boot up times became very slow.
I would turn the machine on and get the chime within 5 seconds or so.
Then just a black/blank screen.
Eventually after about 10mins I would get a white screen then it would boot up normally.
Now the machine just doesn't get to the white screen. So I get the chime and then just darkness. It does sound like the machine is on (usual quiet imac whirring).
I've tried various key commands when I turn the machine on including pressing C with the install disk in the dvd drive and the alt, control, P, R pram reset.
I've also tried unplugging all the cables, leaving the machine for a minute and switching back on. I did manage to perform the PRAM reset once. I reset the machine and it booted fine.
But now when I switch it on just darkness.
I've called after sales and will try to get the machine replaced but in the meantime is there anything I could try that might make the machine work? I need to do a remix this weekend (deadline Monday) so really need to get it working.

View 14 Replies View RelatedMacBook :: It Won't Boot After Trying To Repair With Disk Utility, Cannot Boot In Safe Mode
Jun 11, 2012I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.

Intel Mac :: Boot Partition Error Message - Mid 2010 I7 Will Not Boot Past The Apple Logo
Apr 8, 2012My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

Power Mac G5 :: Cannot Boot From DVDs - Defaults To External FW Boot Drive With 10.3.x
Dec 20, 2007This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.

MacBook Pro :: Boot From External Firewire DVD / Optibay-Boot Camp?
Oct 13, 2010Is it possible to boot from an external Firewire DVD Drive? It certainly isnt from an external USB DVD. Real answers only please, not "I think so" ones based on HDDs or rumours you may have heard!...
Background:
I've got an MCE Optibay in my Mid-2010 i7 MBP. When installing Bootcamp it refuses to install from the external USB DVD drive. In the end I pulled the 2nd HDD out and reconnected the internal DVD. It then worked fine without a hitch. Then I reinstalled the 2nd HDD and all was fine for a few days.
Now I want to resize my Win7 partition (bigger, as MS Visual Studio's bigger than I thought, and I might stick some games on). I can shrink the OSX partition fine with Disk Utility, but windows won't grow the Win7 one because the empty space is before the Win7 partition, not after it. Apparently this can be done with GParted. Guess what? I can't boot the Linux based GParted CDROM from the external USB DVD drive! So, will a Firewire one work where USB fails, and solve my alternative OS booting issues? If I buy one I can then either use GParted, or delete the Win7 partition and start again without having to pull the laptop to bits all over again, only to put it back once I'm done, and possibly have the same issues in the future. Obviously I don't want to blow extra money getting a Firewire DVD drive though if it's a waste of money...
PowerPC :: IBook G4 Won't Boot Past Apple Screen & No CD Boot
Jun 11, 2007I have an iBook G4 1.07 GHz 30 gb 256 RAM with Panther. It was working fine until my HD got close to being full. Now I can't get it to boot past the Apple screen. It will either freeze there, or move on to the blue screen and freeze before the progress bar enters. I want to re-install Panther but I can't get any CD to boot during startup by holding "C", including the Panther OS CD, the Hardware Test CD, or the Tech Tool CD. I am able to boot to single user mode, where I type fsck -fy, and I recieve no errors with the hardware. I had this issue beore and my HD had to be replaced by Apple.

Dec 25, 2008This is the 1st time i got a Mac , i bought a black Macbook 2.4GHz some days ago .
I installed Windows Vista Ultimate using Boot Camp , and all went smoothly .
Only 1 prob is when restarting , i have to wait too long for the Windows to log on , i think about 1min with the black screen.
And if i want to boot in Mac OS , i have to push down the D button or the Alt, it takes quite a long time too .
So do you guys have any solution to this problem ? I want to get rid of the waiting time, way too much.
And do you know how to make my Macbook jump right in the choosing section when it starts ? ( so that i dont have to push down any button when it starts )
OS X :: How To Make Boot Camp OS Selection Default Boot Screen?
Sep 17, 2009Is there a way to make the Boot Camp menu the default boot screen, as opposed to holding Alt? This is the latest SL release, if that matters.
I know this is possible in some manner, our networked iMacs all do it; they start up and give the option to boot OS X or Windows, with a countdown to boot the default OS. I'd just like the same thing to happen on my MBP.

Software :: PowerBook Refuses To Boot And Ignores Boot Keys?
Sep 13, 2009I have OSX installed on a very old Powerbook. Well it was working and then I left it for awhile and now it is giving me the good old folder to question mark screen (maybe someone dropped it?). Well I'm not much of a mac user so I looked up all of the different boot key commands and tried to boot from my OSX CD. Holding down C did nothing, and neither did ANY of the other commands except holding down option and that key command that restarts the computer (apple, option, shift, esc?). Anyway, I got into the screen that shows your hard drive and all other devices and it actually listed the CD drive so I clicked it and clicked the next arrow. I waited for awhile and then the screen reloaded (as if it was rescanning for removable devices) and then stopped and only displayed the local disk. What is going on?! It only sometimes displays the CD in this screen and the next arrow never does anything regardless!!
I really don't know any of the computers stats but if I were to guess they're pretty bad. All I know is it used to run OSX just fine and then other people used it and now it doesn't do anything.
OS X V10.7 Lion :: 10.7 Won't Boot Unless Hold Option Key And Select Boot Drive
Apr 27, 2012Last week I finally upgraded from 10.6 to 10.7, but now my Mac Pro (2008) won't boot properly. It'll start to boot with the gray screen and the Apple logo, but then the entire screen goes gray and it just locks up there. However, if I reboot and hold down the Option key to bring up the list of bootable drives that works fine. I've checked my Startup Drive settings and the proper drive is selected. why it won't boot on it's own anymore? Holding down the Option key is getting old.

OS X :: Does Boot Camp 3.0 Support A Triple Boot System?
Sep 21, 2009I have done some research on triple boot systems, and it appears that a third OS must be run virtually, but all the information I came across was a few years old. Microsoft is running a deal right now on Windows 7 for students so I would like to pick up a copy and try it out.
Is it possible to run 3 operating systems through Boot Camp 3.0? I am not interested in running a virtual OS.

Mac Pro :: Best Setup For Dedicated Boot Drive? - Possible To Boot From RAID 0?
Jan 25, 2009I decided that I couldn't wait for Gainestown and ordered a 2.8x8 MP today. I'm going to get another 8GB of RAM (I assume 10GB in matched pairs will still perform at full speed). My real dilemma is a Boot/Storage solution-I'm moving from a Dual 867 G4, so all my current drives, both internal and external are IDE, which basically means I'm starting over as far as internal drives goes. The G4 power supply gave out so I'm getting this external enclosure to put my old drives into for file recovery. As far as new drives go, I can't figure out what to do. I'll spare you my million iterations of drive configs I've sketched over the past two days.

Mar 28, 2010I run SSD/HDD, my HDD in the optibay is broken, I stuck it in a external and it makes finder freeze, it got bumped around too much so I want to put a new one back in the 'correct place' for a spinner, and stick the SSD in the optibay.(I figure the extra 2% of shock protection offered by the orange rubber circle things is worth the trouble of moving everything).
I am also going to buy a WD 3 platter 1TB laptop drive, and I read that they fit fine in the regular spot in MBP's (I'm going to open and measure in a min.)Anyways, there's no BIOS, only EFI, so how to I pick what drive to boot from? with 10.6 is it as simple as holding option down on boot, and picking my 'OSX' HDD, and then it will auto boot from that until I specify otherwise? (I ask because before 10.6 people on here were always talking about how to switch boot drives.)
