Why won't DiskWarrior boot up my mac? (no entry sign when booting from DW)

I get a "no entry" sign (black circle with a diagonal line through it" when I try to boot from the DW dvd. I'm not sure which type of macbook I have but it was bought in January 2007, and before my file system got corrupted my OS was 10.4.11 . I can boot perfectly find from a Data Rescue 3 DVD (and have already used this to backup all my files) and from the OS X install DVD, so why am I getting this error when booting from DiskWarrior? The apple sign appears and the cog spins for a minute or two and then the no entry sign comes up and stays there...
It's DiskWarrior 4.2.

is this a disc which was mailed to you or one you burned? sometimes their downloaded "upgrades" are just for install only, you have to contact them for the disc...
if this is suppose to be a genuine boot disc, it could just be a bad burn. the boot DVDs should be apple partition map.

Why won't my facetime on my mac let me sign in?

My facetime on macbook air won't let me sign in. I keep trying, and I even tried to create a new user id. I have no idea why it won't work. It keeps telling me to check my network connection and try again later. Everything else on my computer is working. I updated everything, and even deleted the app and tried to redownload it.

Why won't macair boot up?

Why won't macair boot up?

I think you may have to give some details in order to get some meaningful answers. Without details, it could be more than a dozen reasons ranging from a dead battery, bad adapter to a software problem.
Is this running Lion? Have you tried booting to the recovery partition? If not Lion, the recovery disk/flash drive?
Are you certain that the unit is powered (by a chaged battery or a working AC adapater)?

Why won't my laptop recognize my iPod nano second generation when I plug it in via USB? It does recognize my ipad mini. I was hoping to transfer music from my iPod to my ipad mini

1. Update iTunes to the latest version. Plug in your iPod. If iTunes still can't recognize it, then in iTunes in the top left corner click help> run diagnostics. On the box that comes up, check the last two things. Click next and it should identify your iPod.

Why won't my quick Silver power mac boot up? Has a gray screen with white circle with slash thru it in the middle of screen!

Gray Screen with white circle with slash thru? Will not boot up! What can I do?
Please help!

The circle with slash means it cannot boot from the drive it thinks it's supposed to boot from.
Hold the Option/alt key at bootup, what shows as boot choices?
Will it boot from your OSX Install Disc?
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at the top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

Why won't iMac boot off external HD?

Hi I need help setting up a computer and when I connect my external hard drive it won't allow me to boot from it when I start it up holding (option). It lets me pick between recovery and the external and built in hard drive?

If the computere you are setting up is a New Mac and the external hard drive you are using is from an older Mac that is why it won't boot off the external. All New Mac's come with Special Builds of the current version of OS X and they will not boot or run off an older version of OS X Even IF that older version is the same Base version, like Mt Lion 10.8.x.
The version of OS X that is installed on newer Mac's have the correct Drive Package for the newer hardware. The external does not have the correct drivers.

You need a minimum 1 GB of RAM. It has to be of high quality*: http://www.macmaps.com/badram.html
You should also look over this FAQ to make sure you didn't miss anything*:

Note, in event you were interested in Lion, that Mac is not compatible with Lion unless you misidentified it. Only MacBooks with machine ID 2,1 or later can upgrade to Lion (1,1 and 1,2 are earlier). The Machine ID is in Apple menu -> About This Mac -> More Info.

Why can I not boot from a disc or drive?

In order to repair my HD, I have tried to start from a DVD (a bootable DiscWarrior 4 disc), but when restarting holding down the c-key, the disc drive is not recognized and the iMac starts up as normal and my log-in icon is shown. I have the latest Lion update.
I have also tried to start up from a bootable memory stick which I made after installing Lion, but this does not work either.
I have also tried to start up from a DVD using the option key, but the drive is not given as an alternative. The same happens if I try to start up from the "Startup drive" preferences from the Apple menu - the disc drive is not shown as an alternative even if it contains a bootable disc.
I try to get booted from another bootdrive in order to repair the Harddisc.

Hi, StenErik. If I were you, I would forget about FireWire Target Disk Mode. I'd start the Powerbook from a retail OS X 10.4 installer DVD, open Disk Utility from the Utilities menu, select the hard drive, reformat it as "Mac OS Extended (Journaled)", check the box for installing OS 9 drivers, and then install Tiger. I can't explain why this should make the resulting installation any different from what you have installed now. But it seems to me there must be some detail you've failed to mention and we've failed to think of, and that detail, whatever it is, is much more significant than it seems: significant enough to prevent your Tibook from booting. Therefore, reverting to the most basic installation procedure possible, with as few external variables as possible, seems a useful thing to try. To minimize variables even further, disconnect all peripherals from the PB while reformatting and installing.
As Hardy has suggested, the size of your drive is not the issue. A 120GB drive should be fine.

Why can't I boot from the OS X DVD on my Intel iMac?

I'm trying to boot from the Mac OS X Tiger CPU Drop in DVD that came from the Apple Refurb Store with my Intel iMac.
I have tried holding down the C key on start up and it doesn't work. It boots like normal to the hard drive
I have tried using the Start up Manager, but all it can see to boot from is my installed OS X system on the hard drive and my Windows Boot Camp partition.
The CPU Drop in DVD is all that shipped with my machine. Can one even boot with it?
My problem is Photoshop Elements refuses to start up, giving me EXCBADACCESS and KERNINVALIDADDRESS alerts. It crashes every time about half way through starting up. Trashing it's preference folder doesn't fix the problem. In fact, my Preference folder keeps filling up with folders labeled with jibberish names.
I found a discussion thread that I should boot from the original disk that came with the machine and use Disk Utilities, but I can't even boot from the DVD drive.
What step am I missing?
TIA
Kathryn

Hi knittsings!
It's only possible to boot an Intel-based iMac from a grey-labeled DVD, so if you received a black-labeled DVD, someone made a mistake packaging your refurb. The correct DVDs should have been in the smaller box with the User Guide and other small, square documents, along with the mouse and remote. If you find the grey-labeled DVDs in there, just keep the drop-in DVD, they won't need it back since they make them:)
If you don't find them in there, call Apple, or log into your account on the Store page and find your order's link for customer follow-up/issues.

Why can I not boot from my new hard drive?

After replacing my hard drive (40 Gb) with a larger (120 Gb) drive the computer will not boot. I can boot from the 10.4 system CD and have managed to install the system without problems, but after restarting the computer I only get to see a folder with a flashing question mark in it.
My computer is the first of the Titanium series (400 Mhz). The hard drive is a Seagate momentus 5400 rpm. Is there a compatibility issue here? Any input would be greatly appreciated!

Won't even boot from CD?

Hi,
I've got a G4 MMD powermac, and recently is decided to stop booting up. I get a boot beep and it will go to the gray apple screen, but I never get that little grey spinning wheel thing under the Apple. It just sits there forever.
After reading some forums, I found that this may be a problem w/ my hard disk, so I wanted to run Disk Utility to check it. But when I go to boot from the Install CD, (holding down "c" during boot), it goes to the grey Apple screen, the wheel starts spinning, and I can hear the optical drive spinning and accessing the disk... however it just sit there and does that forever. Thinking that maybe it was just slow, I left it for several hours to see what would happen, and it just sits there w/ the infinite spinning wheel...
Anyone seen this before? I'm wondering if it is not a HD problem now... maybe something w/ the on-board IDE controller?
Any help would be greatly appreciated!
Thanks!

Hi
You can connect your Mac to another one via FW and then holding down "T" at startup set it in target mode, and then check your hd from the other Mac.
Or remove the suspect hd and connect it to another Mac, on the internal IDE
or via an external enclosure (FW or USB)
If you remove your hd try to boot without, only from your CD/DVD drive

Why can't I boot from a USB stick Ideapad Laptop?

Hi
I just bought new Lenovo IdeaPad Y510P and i've got a problem with installation an Windows 7 64x from a bootable stick.
The OS on laptop is FreeDOS and from this level a cannot install the windows os. The DOS system won't boot from usb stick and there's no BIOS so i can't set the boot order.
As i try to run setup.exe from d: drive(which is flash drive) i receive message that i cannot open this file in DOS system.
I prepared the USB stick according to this solution:
1) Open a Command Prompt with Administrator privileges in either Windows 7 Pro or Windows 8 Pro.
2) Insert the target USB boot media device into an available USB port.
3) Type "DiskPart" in the command prompt.
4) Type "List Disk” (make note of the disk number of the target USB drive).
5) Type "Select Disk X”, where X is the target USB drive noted in step 4.
6) Type "Clean”.
7) Type "Create Partition Primary”.
8) Type "format FS=fat32 quick”.
9) Type "Active”.
10) Type "Assign".
11) Type "list volume".
12) Type "Exit".
The error still persist and i can't go any further with win installation. I strongly asking for help and advice.
Team please assist.
Solved!
Go to Solution.

Hello and welcome,
Are you booting in UEFI or legacy mode?
IIRC if you want to boot and install in UEFI mode you need to format your USB stick FAT32 (which you did) and enable CSM support in BIOS.
You should also be using SP1 media. If pre-SP1 some additional file manipulation is required to get the installer to boot in UEFI mode.
Installing Windows 7 in native EFI mode from USB
If you're booting and installing in legacy mode (which I suspect you are if running FreeDOS - just a guess on my part) you need to format that USB flash drive NTFS.
(You don't say, but I also assume you've copied the contents of a Win 7 install ISO or DVD to that flash drive...)

Why can't I boot from an external scsi drive?

In a previous post, I mentioned that my hard drive died. While trying to find ways to work around it, I dug out an old 4 GB SCSI drive I used to use with my old Mac, and hooked it up. When I booted from the OS 10.3 install disk, I was aboe to install the OS on the external drive, and choose it as the startup drive before rebooting. When I rebooted, however, the Mac could not see the SCSI drive as a startup drive. I tried it several times, changed the SCSI ID, erased the drive and reloaded the OS, repaired the directory with Disk Warrior, all with the same results.
What am I doing wrong?
Dave

What model SCSI card do you have installed? Some cards are driver-based, like the Adaptec 2906. Its driver is loaded from the boot drive, as the extensions are displayed across the screen during the startup process. As such, drives connected to that type of card can't be designated as the boot device. A newer SCSI card that's firmware-based, like the Adaptec 2930, can be used for booting the computer. If you have a card that's firmware-based, then you may need to update the firmware with a newer (Mac OS X) compatible version.
