I CANT BOOT MY MAC! D:

Last night i added 2GB of ram to my 2006 first macbook, booted osx10.4 and it worked, ned i booted the mac holding down ALT to get to the boot menue so i could boot from CD so i could install 10.6.3 from a retail disk. (I don't know if it helps but i used a external usb cd drive and the once in the mac is broken).
It got about 10% through in the installation then it failed but i passed the part were i had to format my HDD. So obviously i couldent boot the old osx any more but when i next booted it up, if i held C to boot from cd it crashed and if i held alt to acsess the boot menue i would get a black mouse cursor i could move then a blanc screens so ic could do nothing with it. i f it helps since i have a retail osx disk, would t help if i booted of usb (btw, when i presses nothign and tried to boot it showed a grey logo with a question mark in it and it cant find a boot partition) what is the best way to fix this as i cant boot!
plz help

Boot your Mac while holding down the Alt/Option-key until the Boot Selection screen is shown.
Choose your OSX to boot from.
Once in OSX go to System Preferences - Startup Volume and set your OSX to be the default.
Use Disk Utility in OSX to verify disk and repair permission.

Why did you chmod it? This is not in the instructions.

XDM is also not part of the instructions for testing TWM. If you start doing random other steps, we will not be able to help you as we will not understand what state your machine is in.

Please post the *full* output. The server terminated successfully suggests a problem with your xinitrc, so as ewaller requested, we'll need to see that - after you provided the actual output and error messages you are getting.

I have installed windows on the new NTFS partician and cant boot it back to mac

I have installed windows on the new NTFS partician and cant boot it back to mac. I dont think I loaded the bootcamp for windows properly now it is stuck in Windows with no bootcamp icon

Restart Windows, hold down the option key.
If you have a valid OSX install, the drive should appear. Choose the OSX partition and continue.

I do not know about Disk Warrior but if you have a compatible OSX on an external HDD you certainly can boot the MBP. Use startup manager:

PowerMac G4 doesnt boot with Mac Os 9/Tiger

Hi all, so I have a G3 and a G4. On the G3 I can boot without problems Mac OS 9 Retail, on the G4 instead I cant boot Mac OS 9 or Tiger (always Retail version).
The only boot i can do on the G4 is Ubuntu...
I tried so many ways, c, pram, reset-nvram/-all, installing Mac Os 9 on the hd by G3 but without solution...
Some ideas?

Hi, elect86 -
Re OS 9 -
Your G4 (Gigabit Ethernet) model can not use an OS 9.0 Install CD, nor an OS 9.2.2 Install CD.
It originally came with a model-specific version of OS 9.0.4. It should be able to boot to the Software Install CD that came with it, which uses that OS.
It should also be able to boot to and use a retail OS 9.1 or 9.2.1 Install CD. All retail OS 9 Install CDs have a white label with a large gold 9.
It can not use any OS 9.2.2 Install CD - the only OS 9.2.2 install disks released were ones that shipped with certain Macs, and are model-specific to those machines. There has been no retail OS 9.2.2 Install CD released.
Recommendation - if you do not have the original Software Install CD that came with your G4 (Gigabit Ethernet), obtain a retail OS 9.1 or 9.2.1 Install CD.
Re OSX (Tiger) -
If your disk set for Tiger is a retail set, it would have come on DVDs. If the optical drive on the G4 is not DVD bootable, then the DVD set will not work. There was (may still be) an exchange program for Tiger, to exchange the DVDs for a set of CDs.
Another possibility in that regard is that the firmware on the G4 has not been updated to v. 4.2.8. This can be installed provided the machine has a bootable OS 9.1 (or later, but not OSX) installed on the hard drive.
Article #120068 - G4 Firmware Update 4.2.8
If by chance the Tiger install disk set that you have is one that came with a different model Mac, it will not be usable on your G4 (Gigabit Ethernet) machine.

Cant boot G4 tower

hi
ive been running a G4 tower 800mhz at work from an external lacie firewire drive with the latest tiger without any trouble so far.
however, since i took that drive home and connected it to my cube there to transfer some files, i cant boot from it any more.
the drive is completely fine and all my files are ok. just since i reconnected it at work, it doesnt boot anymore
it gets stuck at a standard blue apple desktop background.
ive done most of the things i could think of, including:
- removing any startup items
- single-user mode with some codes to reset vram etc
- verbose mode doesnt give suspicious messages
- verifying the disk using disk utility doesnt give errors
- no third-party ram
any help? what can i do to make my disk bootable again?
any ideas why it became unbootable just by connecting it to another mac for like an hour or so?
thanks a lot for suggestions
maarten

no i didnt boot the cube from the external firewire drive. just connected it. went into my home folder on there, copied the files over, and disconnected it again
didnt do anything more with it
archive and install. sure a solution, but quite a pain. id prefer to find out whats wrong. i thought it might have to do something with permissions, but i repaired those and it didnt change anything. still stuck on startup....

Cant boot HELP

cant boot after i ran out of battery during update later when i recharged it i left macbook on for 12hours without moving off the boot screen (the grey apple with the circle loading thing) i tried repairing it with mac install disk but nothing. not sure what operating system i got it end of 2010

You will need to do the following:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
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. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. 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 Options 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.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.
BTW, your profile says Mac Pro, but you have a MacBook Pro, so you should change it to reflect what you are using.

can any one help me out here, tomorrow I am going to boot it into target disk mode and install from a G5 onto the powerbooks HD doing a CLEAN install and then I am going to try booting it from a DVD and doing another CLEAN intstall just cause I dont trust a firewire install for some reason. I would like to avoid all this mess if possible. ANY HELP PLEASE, either respond or email me tend0 at mac dot com. thanks

haha oh man thanks for startin slow with me, but we are passed that tested RAM, start up items, prefs, tried makin a new user account, as I stated before I can not boot from a DVD/CD.. that was one of the problems so I cant run anything that involves tageting the main HDD while its mounted. I have also repaired perms, ran fsck, tried booting up DiskWarrior(didnt boot from the CD), etc. if any one knows this perticular kernel panic string and can point out what the conflict is I can resolve it but other than that I have ran the run of the mill check to see if everything is in order procedure again and again.

Onyx Maintenance tool - Cant boot back into Startup drive

Hi, my hard drive was fine. But I wanted to run the Onyx Maintenance. The mac restarted and booted into the Onyx osx mount, I than ran a disk permissions. But now I can't seem to restart back into the startup dive. I can see the hard drive and I done a disk report and all is fine. But I can't seem to reboot backplease can anyone help..
OSX Mav
Mac Pro

I held down the option key and the drive was an option as well as the partition. I slected the startup drive and as it started a circle with an angled line appeared and then it jumped back to the OSX Utilities (Options: Restore, Re-istall OSX, Get Help, Disk Utility).
Onyx seems to have screwd up my startup drive, I can see it but just cant boot from it..
Thanks for all the help so far

CDBOOT: Cant boot from CD - Code 5 (Windows 7)

Hey gang,
I been searching for the past 2 days for my answer but unable to find it. Maybe you guys can help me which is VERY VERY VERY important that I get Windows 7 on my Macbook Pro!
I have a Windows 7 ISO which I obtain leggaly. When I turn off my Mac and when it boots back up I keep getting:
CDBOOT: Cant boot from CD - Code 5
I have a "early" 2011 Macbook pro, I made 6 diffrent versions of the ISO (which none work), and Im stuck on what to do next.
I have tried to mount then burn, creat new ISO then burn, and I even tried to change the buring speed to x2. I even tried 3 diffrent types of media too...
I been using the Disc Utility which came with my Mac which is ran by Lion 10.7.2
Any ideas on what to do?

This may be the answer. https://discussions.apple.com/message/10499544#10499544
However, if that doesn't work, why bother with bootcamp? Use a virtual drive via Parallels or Fusion, and run both simultaneously. Rebooting is a pain.

Need to boot broken Mac-Mini using retail Snow Leopard 10.6 DVD

Hi,
In Summary:
==========
I have Mac Mini (late 2009) which does not boot anymore and I need to install Snow Leopard using retail DVD (version 10.6). The OS/installer from the DVD does not seem to boot either. I always very much appreciate the efforts of true geeks. So please, any casual beginner, please do not demoralize with something like "cannot be done" etc.
The complete story:
==================
The start of the problem:
1. All of a sudden, one fine day, on start up, my Mac Mini strated to shut itself down without no apparent reason to me. When trying to boot, it would show a progress bar for about 5 minutes - I am assuming that was disk-consistency check being performed. My best guess is that right after the use of Carbon-Copy Cloner (but I am not 100% sure) it all strated to happen.
2. Performed Mac's Disk-Util check and [Verify Volume] used to display "invalid directory item count, should be 31 instead of 29". Surface scan said disk hardware is 100% fine. Volume Repair never worked, since OS X was installed on the primary disk. I lost the DVDs that came with this Mac Mini, so the option to boot from that DVD and launch Disk Util etc. was not possible.
TechTool Pro - No Help:
3. Started googling and had to choose between [TechTool Pro] and [Disk Warrior], opted for TechTool Pro. Tried its bootable DVD only to learn that TechTool Pro cannot fix it. Again, it's surface scan suggested disk hardware is 100% fine. Sent the details to TechTool Pro support team, they couldn't help either after a couple of e-mails+data exchange. (How do I claim my lost money with TechTool Pro - suggestions appreciated as well).
Googling / Mac Forums:
4. Started looking into forums, learnt that someone had successfully repaired this problem using Ubuntu 11.04 install DVD (i.e., without installing the Ubuntu, but just using its 'try from DVD' feature). I had that handy, but forgot to disable HFS+ journaling before attempting to fix the problem. Anyway, attempting volume repair that way couldn't fix the problem as well. However this step took away my ability to boot from Mac.
5. However using Ubuntu's bootable disk, I could access Mac-HDDs contents - and was able to successfully back-up *all* my important data.
6. Googled and learnt that just attempting to boot using Ubuntu DVD can take away ability to boot using Mac bootable media - possibly due to EFI internals. Suspecting EFI is now corrupt, I tried other 'hacks' like:
6.1 eEFIt Boot Disk - which does not work at all,
6.2 Empire EFI w/ Chameleon - not sure how to proceed with options presented - trying either does not work,
6.3 Super GRUB2 - boots fine, but attempting to boot from Mac-HDD fails after a couple of seconds,
6.4 Boot-132 - boots fine, prompt asks for input, but then I cannot eject/replace the DVD due to Mac-Mini (lack of) design,
6.5 Ubuntu 11.04 / 11.10 - still boots fine - just that I cannot go into Mac-OS-X from here,
6.6 TechTool Pro bootable DVD - which used to boot fine earlier stopped to boot.
As you can see, none worked successfully. So I didn't yet try other popular rescue media - as I suspect that is not the direction I need to go into.
>> Looks like most of my problems are due to the fact that I have Mac-Mini which does not allow eject/replace of DVD from command prompt / out side of Mac-OS-X.
7. Tried emptying EFI partition, playing with EFI/Mac-OS partitions boot flags, Zapping the PRAM, nothing still allows me to boot either from Mac-HDD or any Mac-Bootable-DVD.
Current State:
8. Now while boot time, Mac displays a gray screen for a few seconds, and then a blinking prompt on black background. That's it!
Snow Leopard 10.6 Retail Install DVD:
9. Went to Mac store and bought this DVD only to witness that I can't boot from it as well. (This is a huge shocker, how is Apple able to sell these DVDs if these don't work on genuine MacMini itself. After all we are able to boot from and install Windows/Linux on a variety of Machines).
I am hoping for a very small step/fix that I am missing, since I can still see and access all Mac-HDD contents after booting from Ubuntu bootable DVD. However I am prepared for a good amount of exercise as well - assuming someone posts a valid/verified fix.
Things available right now:
==========================
A. Genuine Mac-Mini (Late 2009) who lost it's ability to boot either from its HDD or Mac-bootable DVDs (TechTools Pro, Mac OS X retail DVD)
B. Mac OS X 10.6 Retail DVD
C. NOT AVAILABLE - DVD that came with this Mac-Mini
D. Variety of rescue DVDs, listed in section 6 above
E. Another machine/PC with Ubuntu 11.04 - giving me ability to access internet
Thanks for reading.

I had a similar discussion recently with another user.
Your Mac mini (late 2009) originally came with Mac OS X 10.6.2 build 10A432 or build 10C2234 see http://support.apple.com/kb/HT1159 it would have come with an original install disc specific to your model of Mac which you could use to run Disk Utility from or to do a complete reinstall.
The retail boxed copy of Mac OS X 10.6 (Snow Leopard) was originally intended for older Macs which had previously come with Mac OS X 10.5 or 10.4. It would have on it a version of Mac OS X 10.6 or 10.6.1 which would be able to boot these older Macs, but had no need to boot newer Macs which were released after the launch of Mac OS X 10.6 since all those newer Macs already shipped with their own discs.
So it is normal that the retail boxed Snow Leopard installer does not work on your model Mac mini. You should be using the one that shipped with your Mac mini instead. I am guessing you have lost it.
Assuming you have lost the Mac mini original disc, I can suggest the following options to try and workaround this.
If you have another Mac, an older Mac, one that will be bootable using the retail Snow Leopard install disc you have, you could do either of the following.
Connect an empty external GUID partitioned hard disk to this other Mac
Boot from the retail Snow Leopard installer
Install on to the external disk
Once the install is complete, update it using the combo update not the one via Software Update to Mac OS X 10.6.8. This will add all the newer drivers needed to allow it to work on your newer Mac mini. You can download this combo update from here http://support.apple.com/kb/DL1399
You can now disconnect the external drive and connect it to your Mac mini and boot from it by holding down the Option key when you turn the Mac mini on
or a similar process if you want to wipe the Mac mini and reinstall directly on to it
Boot the Mac mini in FireWire Target Disk Mode (see http://support.apple.com/kb/ht1661 )
Connect the Mac mini as an external hard disk to the other older Mac
Boot from the retail Snow Leopard installer
Install on to the external disk
Once the install is complete, update it using the combo update not the one via Software Update to Mac OS X 10.6.8. This will add all the newer drivers needed to allow it to work on your newer Mac mini. You can download this combo update from here http://support.apple.com/kb/DL1399
You can now disconnect the Mac mini and boot from it as normal
Note: While the Mac mini is connected in FireWire Target Disk mode to the second Mac, you could backup (if you don't already have a backup) any files you need to retrieve.
If you don't have a suitable second Mac you may have to either borrow someone else's, or get the help of an Apple Store if one is in your area.

How can I set to boot from MAC OS by default after I installed Windows?

How can I choose to boot from MAC OS by default after I installed Windows? I have a MacBook Pro Leo 10.6.8. I used bootcamp to install Windows XP SP2, but now if I don't press the option key it will start up with Windows, and I don't want that. Thanks for any help.

Select it in the Startup Disk pane of System Preferences.
