Can't boot up or reinstall OS 9

Hello, I wrote in last week and received some help, it did not work. I tried to upgrade from OS 9.0 to OS 9.1 I borrowed a install disk, the same one I originally installed with. This time when I start up holding down the C key I get a message that scrolls up the screen...
It reads:
Default Catch, Code=300 at %SRRO: (this part changes)
%SRR!: 0000b030
This scrolls on forever with the #'s behind the first %SRRO: change they all start out ff8*** and then keep going and going.
Does anyone have any ideas? or can anyone help me?
Thanks,
Tom D. Kerrigan

It's hard to follow a new thread insterad of last week's…
Could you please repeat what you wrote last week, together with what was suggested that didn't help, and whether that made any difference at all?

Inadvertently converted disk to dynamic: can't boot OSX or reinstall

Greetings Folks,
I am on a mid-2012 MacBook Pro 13 that received a few days ago so first ever post on a Mac forum - hope it's as friendly and useful as the one over at Lenovo.
Just came back to Mac. Long story, boring details, but in addressing an 18-month old tantrum and in a Homer moment I was being inattentive and converted my HD to dynamic under Windows 7 while trying to convert a partition to exFAT for sharing files.
Like some noob fool I did not make recovery disks at the get go and the fact that there were no disks shipped with the machine didn't register as it should have (my only complaint regarding the product - the rest is ALL my bad). And no, also like some noob fool I did not, having seen it for the first time, tuck anything into Time Machine either. So it's the short and curlies for me...ah yes, and under Internet Recovery when I tried to access the installation and recovery option in Safari, it told me there is no machine registered under my name, something I thought was addressed when I first accessed updates and etc. from the AppStore.
To get on with it, I can't boot into OSX and I can't erase the HD uneder OSX Disk Utility either - I am in Viet Nam and internet is slow so everytime I resort to CMD R to get Internet Recovery it takes hours to load. Verify says the OSX Base Operating System is ok. Error messages I get:
"Couldn't modify partition map" when trying to erase the OSX partition for a reinstall of ML;
"Couldn't write installion information to disk" when trying to reinstall ML and no disk visible to select
From years dealing with Windoze I know that there's only a clean wipe and reinstall to go back to NTFS from dynamic, so I suspect I will have to completely wipe and reformat the HD. I already tried wiping the original partition under W7 but still can't get Disk Utility to do anything with it. So my question (assuming a fool is correct) is this:
What is the best tool to wipe and reformat the HD to something my MBP will then recognize and I can (go through the days it will likely take to download and) reinstall ML?
Or is there an easier, softer way? My Spidey Sense says no...

Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

I'm getting the grey screen during start up and can't boot the computer. I did a cmnd R but worried it would automatically wipe my hard drive and reinstall OS. Is there a risk at cmnd R will result in wiped HD without me actively making that choice?

I'm getting the grey screen during start up and can't boot the computer - MacBook Pro with lion.
I did a command r after doing some research but got nervous that it would automatically wipe my hard drive and reinstall OS.
I was nervous because it asked me for language for software use before any options were presented (such as repair via disk utility). It looked similar to an OS install.So I powered off....Is there a risk at command r will result in wiped HD without me actively making that choice?

Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless.

Welcome to the Apple Support Communities
Lion uses Recovery to reinstall OS X. Press Command and R keys when your Mac starts, open Disk Utility, erase the drive and reinstall Lion. The other Mac has probably got its hard disk damaged, so take the Mac to an Apple Store

OSX gone, 9.2 boots, can't open CD to reinstall OSX

I've got a G4 Power Mac that comes with the CD drive that can only open from the monitor. Brilliant! I dragged the computer out of storage (worked fine going in) and hooked up the special monitor (more brilliance) and got a question mark. So after a few restarts, connected it via firewire to my Powerbook as a slave. Ran Disk Utilitiy and it said it was fine. It wasn't. Hooked up again and ran DiskWarrior and it bombed on the replace function. Again and again. Started it up separately and it went to OS9.2 with no way, that I could see, to open the CD drive to install OSX again.
How do you get the CD drive to open on this thing? I've been a Mac-only person since 1985 and have never been so frustrated. Did Bill Gates design this Mac?!

Removing disks:
http://docs.info.apple.com/article.html?artnum=88215
When you stored the G4, did you remove the PRAM battery from the logic board? Leaving it installed means the battery drains to zero in a few weeks and can cause boot problems. One person in another forum found that a dead PRAM battery leaked during storage and the "juice" ate through parts of the logic board. Dead Mac.
Always remove the battery when storing an unpowered Mac for an extended period.

How can I boot to a fakeRAID -Raid0 set drive from a non-raid hdd

Hi all,
First of all, my English is bad and I hope I can explain it what my problem is. Secondly, I need your expert help with my problem right now.
I'll just layout some hardware information and some history before I start. Currently, my motherboard has 3 hdd controllers which are:
1) Intel - 6 ports --> contains 2 sets of RAID drives = 2 x 60gb SSD (boot drive) and 2 x 500gb HDD (data drive) both in RAID 0
2) Jmicron - 2 ports --> 1 port is used by the DVDROM
3) Marvell - 2 ports --> I don't use these ports as they are slow and are so bad - currently disabled in BIOS
HISTORY: Before, my 2 x 60gb SSDs (RAID 0) contained Arch 64 + Windows 7 64 with Grub as the main bootloader. I remembered having a hard time setting up intel fakeraid with Arch linux + Win7 dual boot before, but fortunately, with your help, I found the solution and I've been using it ever since until today.
NOW is kind of a different issue. I bought a new 60gb SSD (just one). I totally reformatted everything with my 2 x 60gb SSD Raid 0 and I decided to just use that exclusively for windows, still in RAID 0. My brand new SSD will ONLY have Arch64 on it. So I installed Windows 7 first on my Raid SSD set. I plugged my new SSD to the Jmicron port so I can take advantage of AHCI. I don't want to mix my new SSD to the Intel Controllers since its not RAID anyway. Anyway, I installed Arch 64 on the new SSD in the JMicron Port fine.
Now here comes the problem, I set the Jmicron port where the Arch is installed to be the primary boot in the BIOS (since GRUB is there) and I can't boot to Windows! It gives me an error that It can't find the target drive (Win7 in the Raid 0 - intel ports). I've tried modifying the menu.lst and trying so many combinations and It still fails. Of course, I can boot to Arch fine since the drive is independent. It looks like grub legacy can't boot to fakeRaid drives if its not installed on that same drive.
Can you give me advice on how to fix this issue?
Also, I was just thinking, is there a 3rd party Windows Bootloader, that can be installed in Raid 0, that can pick up Linux and boot from it. I was thinking of just making the Windows 7 as primary boot in BIOS, with a 3rd party bootloader, then just boot to Arch.
Thank you!

Yes, I have redirected my User folder to the D: drive.
I know that some shared components must reside on the C: drive; that's fine. I just don't have room for the entire installation on there.
The real issue here is that, when a drive other than C: is selected as the destination, the CS6 package installs into a broken state every time, out of the gate, on my system. Some components get installed to D: and some to C:, but the various components of the programs seem confused about what exists where, as shown below:
I select a folder on D: as the destination folder for the install, and here is what I get:
64-bit versions of the package -- Program files are installed to the D: drive as specified, but attempting to start them results in a configuration error message stating that the program must be uninstalled and reinstalled, and lists "Error code: 1".
32-bit versions of the package -- Program files are installed to the C: drive against what I specified. The shortcuts installed in the Start menu for the 32-bit versions point to the locations where these program files SHOULD be, on the D: drive. If the Adobe folder containing the program files is copied over to the correct location on D:, these programs function normally with no errors.
I have the 32-bit versions working by copying the program files from C: to D:. I just want to get the 64-bit versions working as well.
Any help you could give would be greatly appreciated; I'm really looking forward to testing the CS6 suite on my system!

Can't boot up - damaged hard drive?

I've put all info here so hope it helps - 3 questions at bottom.
My system:
iMac G4 800MHz 80GB HD can't remember how much RAM but I think I'd put the max possible in it.
Mac os: 10.4.11
partitioned for 0SX and classic 9.9.2 (approx split 90%/10%)
The problem and what I've done so far:
The machine was running slow, then kept hanging. I checked and there was only 3GB free space so started to clear out some files (removing document files and Quicktime as I was going to reinstall it due to an error I'd received trying to open a movie file). The machine then either got stuck in a loop or hung trying to empty wastebasket. I moved some files from wastebasket to the desktop and moved a few at a time to wastebasket and emptied. Then it kept freezing, and I kept having to force a shutdown by pressing the power key for a few seconds.
During all of the above there was no (and thinking about it there hasn't been for a while now) startup chime.
I tried normal and safe boots and then reset the PRAM. Then it chimed on startup but wouldn't startup.
I've tried starting up from the original OSX10.2 disks supplied with the mac and a OSX10.4.3 disk. Only the latter will boot but only occasionally when holding down the C key on startup. If it does boot up this way it freezes after I get about 20% of the way through using disk utility or I try to install the system software.
Now either using disk utility or system software install, they do not recognise the disk.
When trying safe, single user and verbose boots, after about (est) 2-3 mins I get after about half a screen of text ending with:
diskOs10: I/O error.
Invalid key length
(4, 16111) -which I assume is the problem location on the disk
** volume check failed
syncing disks... Killing all processes
continuing
done
CPU halted -then the computer turns off.
As I haven't opened the computer up at all, I was hoping that it was a software problem that could ulimately be resolved by reformatting and reinstalling system software but with all the forced shutdowns and restarts (including having to restart with mouse key held down to remove/change installer disks) I fear the worst and think the hard drive is terminal or an outside chance that the superdrive is somehow at fault.
All of the above has happened in the last 24 hours.
I would like to try to at least copy off my email messages (100's) before giving up and replacing the internal hard drive.
Three questions:
1. Is there anything else I can do to try to reinstall system software?
2. I also have a MacBook (OSX 10.5.7) and a couple of LaCie 250GB firewire drives - is there any way I can hook these up or boot from the the MacBook or its DVD drive to see what's on the iMac G4 in it's current state?
3. Is replacing the hard drive straightforward or should it be done by a pro? (back in the day I often switched and replaced internal hard drives in old beige macs 6100's and as recently as tower G3's/G4's but I haven't looked inside a iMac other than to add RAM.)
Please help!!

Success! - this was my solution - it may help someone else avoid the three weeks of trial and error that I've been through.
I tried an older version (3.0.2) of DiskWarrior without success (web info suggests I'd need 3.0.3 or later) but I had managed to create disk images (.dmg) of the old partitions using DiskUtility onto an external firewire drive which I could mount successfully. At this stage I could to see all of my original files so rather than upgrade DiskWarrior on a 'maybe', I bit the bullet and reformatted the disk with the same size partitions and names as before in the hope that I would be able to clone from the dmg files.
I reinstalled OSX 10.3.4 and updated to OSX 10.4.11 to get back to where I'd started. I then tried using Carbon Copy Cloner to clone the disk images onto the new partitions but it kept crashing after a few hours. I also tried cloning to another IDE drive in another G3 (running 10.3.9) which also crashed. This left me thinking that the original problem had been that the hard drive was somehow in a knot and the 'knot' was still contained in the dmg file.
When I reinstalled OSX 10.3.4, I couldn't avoid using the setup assistant but as I didn't know a lot of the settings (I guess there are ways of getting this info from the dmg file but I didn't know how to and also, I wasn't sure if using OSX 10.4.11 settings in OSX 10.3.4 would cause more problems) I just entered basic details, restarted and updated to OSX 10.4.11. I then ran Software Update which updated a number of items.
I then used Migration Assistant to copy all of my settings and applications from the mounted .dmg file and it recovered most of my settings and applications. The applications work pefectly and didn't even ask for serial/validation details. I needed to spend an hour or two comparing two finder windows - one showing the mounted .dmg disk and another my new hard drive replacing newly installed Mail, Address Book and Safari files with the files from the .dmg file (Users, Preference and Application Support files etc), a restart or two later and it all appears to be working perfectly including all of my mailboxes, messages, contacts safari favourites etc .
Amazingly, it's a 80GB hard drive that I know was pretty full (showing only 3GB free) when I had the crash, the .dmg file is 67GB but now only 43GB disk space is used! As far as I know I haven't left anything out that I had on the disk before but as it all appears to be working well I really don't care!
I've already made new disk images!

Can't boot G5 even from OS install disk. Help?

I've trolled the message boards 25 pages deep and searched all the "Can't boot my G5" threads and still haven't found anyone describing what my machine is doing so thought I'd start a new thread in the hopes someone can help me out.
Ok I have a G5 dual processor machine. (Power PC chip, not Intel) Things went bad when I tried to do an Archive and Install of Leopard (OS 10.5) The install looked as normal until I got to one minute left on the install. At that point the install never progressed. I thought maybe it was doing some behind the scenes processing and decided to leave it over night. The next day my machine was still hung on that One minute left. So obviously it was a failure. Of course now the problem is I have an install that never completed of the OS and so that partition is, I assume, unbootable. Wiped away the Tiger OS and did a 99% install of Leopard. So I had to shut down by holding the power button.
I think to myself, "No worries I can just boot from my 2nd partition holding down the Option key to select it on the boot up screen". I always keep a partition with an OS on it for times like these. So I reboot, hold option key, select my other partition, things look OK. I get the grey screen with the Apple logo and I get the wheel animation turning. (Not beachball of death but the typical circular, almost sun ray configuration thing) At this point, usually the screen will go black for a moment before the desktop loads. However, in my case once the screen goes black after the load screen, it stays black. Now let me say the monitor does NOT turn off. There is a definite difference when I manually turn the monitor off. When off it's truly black. But this is like a power on black, not true black. (If you need me to explain this better feel free to ask me to clarify)
So the untouched, pristine Tiger partition boot is a No Go. I figured I'd then give up on trying to put Leopard on my desktop machine (I use it on my laptop) and reinstall the original OS and system software from the system disk that came with my G5. I boot machine holding down eject button, place the disk in, close the drive door and shut down again by holding power button. Reboot holding C key and the same routine happens with booting from the disk. Gray Apple logo screen, sun ray circle moving, screen goes black on the attempted transition to desktop .. but stays black. I also tried booting with my Disk Warrior disk to no avail. Same thing happens. (Also tried booting from disks by selecting them manually from booting with Option key down) At first I wondered if it was a monitor issue. That maybe my desktop was up but there was an issue with the signal being passed to the monitor on the resolution jump. Thought perhaps hitting the Eject key on the keyboard when I had attempted to boot from the partition (not from disk on this test) would tell me if it was a monitor issue. If it was a monitor issue, the disk tray should open. But alas, no.
So since I cannot boot normally from any partition or disk I decided to boot into single-user mode.
I did the fsck -fy thing and it told me everything was ok. I had also previously installed applejack and I ran that and short of correcting a few permissions and dumping some unneeded caches it came back with a system OK.
At my wits end I booted into target disk mode and ran Disk Warrior on both the original half installed OS partition and the back up emergency boot up partition from my laptop. Again, everything OK. Hoped against hope that I could actually install an OS onto my G5 from my laptop but I was only given the option of being able to do it from my laptop with the Leopard disk and it would only allow me to do it if I used Disk Utility to completely format that drive first. No, thanks.
Re-attempt to boot G5. Failure. So now I turn to hardware. Disconnected everything beside the keyboard and mouse. Try again. Fail. Pulled a couple sticks of Crucial memory out of the machine and left the stock RAM. No dice. Pressed the small power unit reset button under the RAM slots. No change. Zapped the PRAM. Still nothing. Try to boot in Safe mode holding down shift key. Doesn't work.
It seems to me if I can't even get the machine to boot from the Install disk that there is something going on that is much more major than software issues.
Bad motherboard? Any ideas? Because I'm all out of ideas.

Brother, Sound74, I thought I was the only one pulling the hair out of my chest one by one the past two days. Your situation is very similar to mine, and I'm just as clueless as you are. I started getting kernel panic screens, then nothing on boot, until finally I brought it to the local genius bar. They ran all the usual software/hardware tests, updated Tiger to 10.4.11, recommended I buy Leopard and do an erase-install. My computer, of course, was working absolutely fine by this point. I bought Leopard, came home, backed everything up, then tried to install the new OS. Like in your case, it just up and quit half-way through. Screen went black and a "No DVI Signal" message came on my display (it does this when I turn it on without first turning on the computer).
So I thought, well, maybe it takes a really long time to erase-install, and the monitor is just waiting for things to kick back in. I've always upgrade-installed before, so I couldn't tell if this was normal or not. But about half an hour later, my fans kicked in so fast I thought I had a P-51 Mustang taking off in my studio. I waited a bit more and finally force-shut-down my system. Not knowing what to expect, I nervously tried to re-boot.
Nothing. Zip. I can't safe boot, I can't boot from the installer disc, etc. The only thing I can do is the option-key thing whereby you choose the startup disc. And of course, it only gives the Leopard install disc as an option, because now the entire HD has been erased! But when I choose the Leopard disc, of course it doesn't work.
So I have a nice $3000 paperweight sitting in my studio. I guess I'll have to bring it back to the Mac store, where if it costs more than $300 to fix, I'm going to say screw it and put that dough toward a new iMac.
Sorry I couldn't provide any helpful info, but I just wanted you to know you're not alone in suffering the slings and arrows of outrageous technology.
Keep me posted on any solutions you discover, and I'll do the same.

I tried to reinstall the machine, but during the install process the installer isn't able to create a swap partition. Later, I got the error message "stale NFS file handle" at the console (I don't do anything with nfs here). Same errors with kvm-87 and 88.
I tried to install other distros, but any of them failed to install on the virtio disk one way or another.
Everything works with kvm-84. With kvm-85 libvirt (which I am using) wasn't able to boot from a virtio disk. Note that libvirt has nothing to do with the error/bug described above. This happens since kvm-86 with plain kvm started from the command line, too.
I am switching back to kvm-84 for now.
To reproduce:
Get a Debian Lenny qemu/KVM image and virtio disk and try to boot it. Or try to install Debian Lenny on a virtio disk. There were other errors with other Distros, so I suspect that there is somesthing wrong with kvm since 86.

I am also having the same problem, the host is Archlinux with kvm-88 on 64bit, I am going to try aur and see how it goes when I get home.
There is no updated aur package so downgrade it is.
KVM 84 didn't work YES!!!

Can't boot from cd

Just replaced a hard drive in my old G4 titanium laptop and it worked fine until I did the OS update. The first time i did the update and clicked restart, it would only go to a black screen. I reformatted and thought I would just say to he'll with the update and leave well enough alone. My wife used it for a few days and said it was really slow, so I did the update again. I selected one update at a time and when I did the Security Update 2009-005, it gave an error and said try the install again. I rebooted and now my dock has dissapeared and when I try and reboot, it does nothing. I tried to run disk utilities and the program will not open. I tried to reformat the hard drive, but when I hold the C key down to select the DVD to boot and install from, it goes back to my hard drive and just boots to the installed OS. I then tried to select the DVD from my preference start up disk option and there is no CD/DVD option to select as boot drive. I see the mounted DVD disk on my desk top and can access the files on it, but can't boot from it to reinstall. My install was Tiger full retail. The laptop came with an install disk that had Panther. Any ideas would be appreciated.

Thanks for your reply and yes I did try option as well, with no luck. I finally reformatted through FireWire and another laptop. I am now installing from the disk that came with the G4. So I will try Panther to Tiger even though my Tiger is a full retail disk. I am not sure why Apples up dates to 10.4.11 crash this g4, but I'll try for the third time and see what happens.

Can't boot into Mac OS after Windows install via Bootcamp

Hello.
Last night I installed Windows 7 on my Macbook Pro early 2011 via Bootcamp.After some major complications I was able to finally install Windows 7 and boot into it. Now I can't boot back into my "Macintosh HD" partition, it shows a no entry sign.
Hard Disk : 320GB Internal Sata
Partitions : 3 -> Mac, Bootcamp and 10.8 Recovery Partition
The good part is that I can still access the Mac OS partition in Windows and Windows is working perfectly fine. As a matter of fact right now I'm on the bootcamped windows.
I have a full time machine backup but still I am looking for a way to solve this without formatting the HDD.
Things I have tried:
1. Resetting NVRAM and PRAM
2. Booting into 10.8 recovery partition and running DU.
SMART Status : Verified
"Macintosh HD" grayed and Not Mounted
Successful Verify Permissions (Twice)
Is there a way to solve this? Though the Mountain Lion partition shows when I press the Alt/option key on startup but I can't somehow boot into it.
Thanks

Your problem is OS X is refusing to boot.
There is still a bootable volume on the Macintosh HD partition, it's just not working.
You can #8 Reinstall Just OS X while command r booted from the Recovery partition, as long as you don't use Disk Utility to erase the Macintosh HD partition, your files and programs remain.
Hook the computer via Ethernet cable to a router (or modem, power reset required) with a fast relaible internet connection, you will need your AppleID and password to reinstall OS X.

Snow Leopard corrupted main Mac HD,..can't boot to it HELP Please!

Boy did I have a day today!!
A couple of days ago, I achieved and re-installed OSX 10.5. Upgraded to 10.5.8. Then, I installed Snow Lep and upgraded to 10.6.2. Now, I did all of this in safe boot since at the time, my graphics card was broken. I got a new one today and everything was fine. After I installed all the OSX stuff, some of the programs did not work, such as iCal (said this version does not work with the current OSX version) Spotlight (no response) and Preview (no pictures, just a blank screen).
I called Apple and they told me to re-install SL. I re-started from the CD and the install started. BUT, then a window came on saying the installation failed. So, I restarted again, and same thing. Then, I decided I just leave it for now and just restart and log back in. WRONG! No more Mac HD icon. I now was only able to boot from the CD (no Mac HD icon). I then partitioned part of my other internal HD and tried to install SL on that. It failed on that one as well.
THEN I tried to install 10.5 AND, it worked. Sorry for that long explanation.
Now, I don't think I can get back into my main Mac HD( Can't boot from it). I can get into it from this partitioned one to get files. What are my options now? Can I try to do a repair? If not, I guess I have to do a clean install of 10.5? If that's what I have to do, how would I go about that? Disk Utility, select Mac HD and erase? If yes, which erase? Don't erase Data? Zero out Data? Or is there anything I can do to fix my main drive from the internal Im currently on so I can boot back in?
Thanks in advance for help! Greatly appreciated!!
I get the feeling that I got a corrupt SL install CD.

In a situation that complex I can tell you what I would do (after roughly 25 years doing tech support). I would get all the data files off the drive to another hard drive. I would then back them all up to a second hard drive and I would verify that they are there and that each of those data drives was "good" using Disk Utility and Disk Warrior. Once I had all the data, including email, desktop files, documents, music, pics etc etc and I knew they were backed up independent of the problem drive I would wipe the drive entirely - partition it. Then I would erase it with zeros - a potentially long process but worth the effort IMHO here. Then I'd reinstall 10.5, update fully and go to snow leopard if that's what you want to do. In that process I'd search on any hardware that could be problematic as well as third party software that could have issues. Whether it's 10.5 or 6, I'd update fully and then connect one of the external data drives and copy back documents and other data after all your applications were installed and updated and known to be working. That is a long, obnoxious process. I keep my own "time machine" by having an external boot backup that I only overwrite every once in a while when all is acting solid. A second boot drive backup is made regularly before any major app installation or before any OS update. That way can easily roll back to a recent state or if needed roll back a bit further. All my data are backed up to external drives with the critical stuff backed up twice. It's easier than it sounds with CCC or SuperDuper and in the long run can save hours upon hours. I've been in your shoes and I wish you the best of luck. As long as your data is intact, everything else is just a time consuming pain in the butt.
your SL install should do a thorough checksum verification before it installs. it's not impossible it's still corrupt but unlikely ...assuming you let it do the entire verification.

I have lost my cd's and screen became gray i can not boot what should i do?

Hi all
i have lost my cd's and screen became gray i can not boot what should i do?
i have tried to reset Vram
tried to run safe boot
but nothing happends
i have a macbook pro core 2 duo 2GB ram 160 gb hard disk

Use the computer your on now to download and burn a ISO of PartedMagic to a cd.
In Windows 7 you can right click on the downloaded ISO and click burn to disk, other Windows versions use the free ImgBurn software.
In OS X you can burn the ISO using Disk Utility.
Hook up a external drive to the target Mac.
Stick the PartedMagic disk into the Mac and reboot holding option and c keys (I forget which one works)
Use the first option (default) to load PartedMagic into memory (watch out the disk will eject!)
Once in PartedMagic there is a Mount Drive icon on the right, doubleclick it twice to open two windows (three total) you can now transfer your files after mounting the disks/partitions using the two open file windows.
Unmount the drives before using the "Start" like menu in the lower left corner to quit PartedMagic.
If your Mac works with all this then your in good shape, you just have a hosed operating system and a $29 Snow Leopard install disk (c boot off of it) and a Disk Utility Erase (with Zero Erase preferred) and a reinstall of OSX Snow leopard will do the trick.
If your computer boots off the PartedMagic cd, but you can't find/access the internal drive, then your boot drive is dead and you need to replace it or have someone replace it for you.
If your computer doesn't boot off the PartedMagic cd, then it's likely a serious hardware issue.

Can not boot from OSX disc

I recently partitioned my internal drive with an 80 gig partition to run Ubuntu , removed Ubuntu and now can not resize hd to recover the 80 gig that I used , there was a program with this Ubuntu install called rEFIt that was installed for the dual boot , My problem is that Itunes keeps crashing and I have spent somewhere around 8 hours trying to fix this issue and in the process I discovered that I now can not boot from the osx disc but I can boot from the Ubuntu disc , what can I do to correct this issue or is there anything that I can do to correct this and recover the 80 gig that I used ?

The only solution was to erase hd and restore from time machine backup......
According to everything that I have seen , read and tried when you partition the mac hd the way that mac is designed it will lock the hd thus preventing any access even using the startup disc to repair. As far as restoring everything after the erase and reinstall of the OSX that was easy and painless. FOR ANYONE WHO DOES NOT BACKUP THEIR DATA THIS IS WHY YOU SHOULD!!!!
Once OSX is reinstalled the migration assistant will ask if you want to restore from a backup , if you have time machine or any other sort of backup simply choose the one you wish to restore from and continue , must admit I was a bit hesitant at first , I must say that everything restored with the exception of some settings that I have had to restore but they were not major settings , after the backup is restored simply run update check and reinstall all updates , may need to do this a couple of times.
Depending on the amount of data you have will determine the length of time for restore (500 gigs about 6 hrs.) but it will restore user account settings , connection settings and network settings.
Hope this will help if anyone has experienced the same problem.

Can't boot after system update: unknown filesystem type

After running a system update, including updating the kernel, I can't boot to the new kernel.
On booting, grub loads the kernel image, runs/loads udev, but then fails to mount the root partition with error:
mount: unknown filesystem type 'ext4'
I have tried reinstalling the 'linux' package via packman several times, also trying the --recursive argument to make sure all my dependencies were there, and after days of googling and tweaking my system, I'm at a loss.
Thank goodness I happened to keep a spare kernel laying around in /boot.
Thanks in advance.

The OP can read their partition initially though, it's only after udev that they can't.
Also, try adding "rootfstype=ext4" to your grub kernel line. Is your /boot on a separate partition or part of your / partition?
