Booting to install CD

Disk Utility states I need to rebook into the cd to repair the main internal drive. I placed the Snow Leopard upgrade, Leopard install or application Dvd into the machine. I tried holding down the C or D or the other key combo while either restarting or shutting down and rebooting. it still goes to the normal log fin and then desktop when I input my name and password.
Help please! I tried C or D or the keyboard combo but it will not boot to the DVD.

Try as an alternative to insert DVD an hold the option Key down on reboot

I have a copy of Windows 7, and I am trying to bring up Boot Camp on my MacBook with Snow Leopard. But my Snow Leopard install disk is too old for Windows 7, so attempted Boot Camp install of drivers fails.

I have hand-installed the NVidia graphics driver, and I have keyboard, minimal trackpad, and hardwire to internet all working. So the WIndows machine is usable. But I am hurting for wi-fi, better trackpad, and whatever else is delivered by Boot Camp. I can't use any of the Boot Camp upgrades because I do not have XP or Vista.

While we all have MacBooks in this forum not all of us use Boot Camp. There's a Boot Camp Support Community where everybody uses Boot Camp. You should also post this question there.

New Macbook Pro retina boot camp install issue - Windows 7

Trying to complete a boot camp install but can't get past creating a partition. I am able to download the windows drivers through boot camp, it burns them to a DVD, verifies the DVD (couldn't use CD-R as it kept saying burn failure after verifying files) and then takes me to the make a partition page. When i click install the partition, it pops up saying "can't find the installer disc" and wants me to put one in the super drive. What gives? I have that disc in the drive, also tried the Windows 7 disc and got the same error. So basically I can't create a partition to install windows 7 that I have.
Any thoughts?

The disk was from my other PC system, however it is an OEM upgrade disc. Maybe that is the problem but if that is the case why did it work when I installed it through VMware and it worked fine? The disc can be used as a self full install of windows 7. I have also it on another PC with no issues. Trying to convert to Mac finally but this is causing a hiccup.
The next question then is do I really need to go the boot camp way? I only need it to run quickbooks (need windows version for reasons) and a couple of other programs but thought it may run better as a boot camp install rather than VM plus I couldn't figure out how to reduce the size of the partition that VM installs, it takes too much space from me for no reason (60Gb).
Thanks for any input.

Mac Mini won't boot with install disk

tried booting with install disc in and pushing "c" on keyboard and doesn't work. Using a apple wireless keyboard. Also used the keyboard that came with Mac Pro but didn't work nor did a wired logitech.
any ideas?
Thanks!

+What is the source of the idea that the mac aluminum keyboard won't work with the mini?+
Dozens of reports in this forum over the past year.
Keep in mind that by "not working" what was meant was that the startup keys wouldn't work. The Alu keyboard otherwise works fine with the Mini.
It has also been reported that the Alu Keyboard does work for startup keys if it is plugged into a hub with an external power supply.

Windows 8.1 Pro not booting after install of Hyper V - ASUS z87 + intel 4670K

Hi,
I am running windows 8.1 pro on a intel 4670K 4th Gen Haswell CPU and ASUS z87 plus motherboard. 16gb of kingston hyperx ddr1600 memory.
I have enabled virtualisation technology in the bios. CPU has SLAT.... or Extended Page Table, as intel likes to refer to it.
When I install HyperV platform and management tools the computer configures and reboots
AFter reboot it brings up the blue window image and spinning circle of dots for a while then reboots. It does the same thing again and then reboots and goings into repair mode and asks me to do a system restore. It then restores to before they HyperV install.
I've tried turning off xHCI mode (i.e USB 3.0) in the bios as this seemed to be a known issue with some gigabyte boards. This did not rectify the issue
Updated to latest asus mainboard bios 1405. Same issue still occurs upon install of hyper V.
Automatic repair does not work and I have to restore from system restore point.
I performed a clean boot after installing the feature and it still couldnt boot to windows.. it just sits at windows logo and then restarts a few times and then launches the startup repair. Once the startup repair begins, the only way I can get into windows
is restoring to a system restore point from before the hyperv feature install.

I logged a job with asus support and their response was:
"Clear CMOS and ensure virtualisation technology is turned on in BIOS. If it still doesn't work, seek assistance from Microsoft"
Previously asked this question but took a while to get back to update with the logs and it was listed as Answered.
This issue is still existing and I'd appreciating any assistance.

Will Not Boot from Install Disc & 4SNS/1/40000000: TG0D - Thermal Sensor?

*Will Not Boot from Install Disc*
I used the "option key" approach with the gray start up disk. At first it ejected the start up disk. Then I nudged the disk back in the machine and it showed on the screen as an option. I clicked on the start up disk image and it finally loaded.
But, it won't accept the start up disk when holding down the "C" key at restart.
*4SNS/1/40000000: TG0D*
I did an Apple Hardware Test and received the following diagnostic:
Version: 3A121
Test Suite: Extended Test
Loop Count: 2
Result: Failed
Failure code: 4SNS/1/40000000: TG0D
*Thermal Sensor*
A search for the failure code 4SNS/1/40000000: TG0D brought up an Apple Discussion topic entry stating: That error code indicates a problem with a thermal sensor. It could be not working or possibly not connected. You will need to take it to Apple for repair.
Would a thermal sensor have anything to do with it not starting up when holding down the "C" key at restart? What are thermal sensor problem symptoms?
*User File Folder Opened Up*
The machine also starts up with my user file folder opened up rather than with a blank screen as it normally should
I completed a DiskWarrior rebuild on the disk and verify disk shows it is fine.
Any suggestions on what to do next with these issues?

The answer was in your post: "You will need to take it to Apple for repair."

Will not start even in safe boot after installing latest camera update

MacBook Pro will not start even in safe boot after installing latest camera update.
I started my machine and did a software update. Only the camera update needed. So installed and when required I pressed restart. It restarted and did install. Then restarted again. I expected to get to the login screen and it turned itself off. Tried three more times. Each time shutting off. I unplugged everything, and pressed start waiting for log in window. No it shutdown before the log in window. I then tried safe mode and that did not work either on three more occasions.

I have managed to resolve some issues. I can now restart the machine via a CD boot. If I do cmd C into something like tech tool pro, then restart from that disks menu it restarts every time.
If I try a safe start it shuts down. If I try a normal start it shuts down. I have managed to repair permissions and that cleared up some start up permissions but with no improvement to the boot problem. The only way to load is via the cmd-C boot option. Any other ideas?

Macbook pro won't boot after installing update 10.9.3

macbook pro won't boot after installing update 10.9.3

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

How do I boot or install Mac OS X 10.4.11?

I have 10.4.11 on disk and copied it to a flash drive, can someone tell me how to boot or install it on to my old iMac 400MHz PPC less than 512 MB SDRAM Computer? Even Ideas Are Ecepted! Please help. I cant install it to the computwer because the slot dvd reader wont work or i'd be fine. Thnx in advance!

You cannot boot that old computer from a USB port, as I recall. But you can try:
Boot Using OPTION key:
1. Restart the computer.
2. Immediately after the chime press and hold down the
"OPTION" key.
3. Release the key when the boot manager appears.
4. Select the flash drive's disk icon.
5. Click on the arrow button below the icon.

Boot camp install would error out

I had multiple issues as well.
When I first tried to install 8.1 full as a fresh boot camp install it would error out and say that the required files were not there to install.
Then I would try it again and it would then get close to finishing and say it cant change the boot order and fail.
Apple please fix as soon as possible.
<Re-Titled By Host>

What's happening here is that the Windows installation, for whatever reason, is not booting properly. It is also set as your default boot system. To change this, reboot your mac while holding down the Option/Alt key. After awhile you will be presented with two icons, one for OS X and the other for Windows. Select OS X and then press Enter.
OS X will boot. Go to System Preferences >> Startup Disk and then select your OS X partition and this won't happen anymore.

RMBP A1398 - unable to boot and install OS X

I changed keyboard from japanese to norwegian and the bottom cover. This went without complications.
When I booted with new hardware - just grey Apple screen and a spinning wheel that stopped. Trying to recover, internet recovery, single mode, securety mode or all other suggested boot methods fails. It will not boot or install OS X. Hardware test simple and extended shows no problem with memory (16bg) and the 500 gb ssd.
I have of course tried reseeting pvram..etc nvram...
Using thunderbolt and another mac gives me access to the 500gb disk in my rMBP 15". I can even install Maverick using another MBP, but my rMBP will not boot even when OS X is correctly installed (boot the other MBP via thunderbold and my rMBP is OK).
I can install Windows 7 and 8 without any problems, but I need to have OS X installed. I used Mavericks and Windows 8.1 in bootcam earlier.
Linux rescue disk like Systemrescue boots correct and GPARTED can be used to partitionate the disk and formnat it as GUID disk. But trying to boot from a bootable USB or DVD using SuperDrive always stops after the Apple sign and spinning wheel stops.
Could it be the EFI bios settings? Is it poosible to update EFI without OS X installed? Any suggestions?

@killerpollo ,
Hello and thank you for posting on the HP support forum. The first thing I would try in this situation is to download and burn the ISO from another computer.
If you have already set your boot options to boot to CD/DVD and a new dvd is still not reading you may have a hardware issue with your dvd drive.
Does the DVD drive read dvds when you have booted up to windows?
As well I would try putting the image on a USB drive and try that.
I find on occasion when I use the windows software to make an ISO it is hit and miss. There are other software out there that you can try and some are free or what is known as share ware.
Now even if you burn a good image you started with a Windows 7 system. The actual image is more than a UEFI and you will not be able to read it if you system is set as a legacy system.
here are some things you will want to check out.
Boot UEFI or Legacy ---- tips
About UEFI and the Startup Menu
Free Image burn website.
Now if your system came with Windows 7 the product key that you have for your system will not work for Windows 8.1. This is one thing you will want to consider.
Let me know how things go.
Thank you again for posting and have a great day,

Yosemite boot camp install on /separate/ drive?

i have an existing windows 7 boot camp install that resides on a drive in my 2006 mac pro with my LION OS.
i now have a 2012 mac pro.
should i install windows 7 with boot camp on a SEPARATE drive or can i put it on a partition on the same drive as yosemite?
thanks

OK. thank you.
so i /like/ the idea of having an internal CLONE of my OS in bay 1 on the drive in bay 2.
in the past i have set this to happen nightly and i use WinClone (thanks hatter) to create a BACKUP of the Boot Camp install of Windows 7 and i drop this backup on the DESKTOP. this way i have a BACKUP of Windows on my boot OS and i also have one on the CLONE.
just to confirm - no reason as far as you are concerned to change this?

Ibook g4 won't boot from install disks

Got an ibook g4 1.33 ghz combo drive from original owner w/install disks. I want to reinstall original system but it won't boot from install disk 1. Tried starting holding down c but ignores disk. Holding down option just gives me the HD. Install disk shows up on desktop and opens. Tried disk utility from install disk but it doesn't allow me to erase the hd. Is there anything else I can do? Thanks.

OK, so let us suppose that you have the correct disk, the possibilities are:
• the optical drive is not functioning properly. However, since the disk shows up on the desktop the drive is apparently reading it.
• the disk itself is the issue. It could the wrong disk, but let us assume it is not. It could be damaged so that it is no longer bootable, or it could dirty. I would begin by giving the disk a good buffing and see if that will encourage it to boot the computer.
Good luck.

IMac OS 8.5 Boot Issues - Install/Format HD/Select Startup Disc?

Hello,
I have a used iMac that had OS 8.5 installed. When I first booted, it appeared there was no OS installed (flashing icon - folder with "?" and Folder with OS icon). Attempted to install OS 8.5, but get the same error after reboot.
Tried to use 'Initialize Disk' to reformat the hard drive, then installed OS 8.5. Same error on reboot. Have tried using the Startup Disk (?) option to select the hard drive, but there appears to be no option save to click.
I don't know about Mac and Master Boot Records or if there is a Mac CMOS. Any ideas on what I am doing wrong?
Thanks,
Dave

Just might be a hardware issue. Here is what I tried this morning:
Reblessed system, booting from install CD.
System Error on reboot - address
* Occasionally on this error, the system will not reboot then the "reboot" button is pressed. Power button non-responsive. Have to shut down the old fashioned way - yank the power cord.
Startup from Install CD with no extentions.
Initiated HD, 1 partition, Mac Standard.
Rebooted system.
Began Installation with "recommended installation" for all items.
Reboot - same flashing icon.
Boot from install CD, address error.
Reboot with no extentions.
Erased HD (Selected HD Icon | Special -> Erase Disc)
Reboot with install CD
Ran Disk First Aid on HD - checked out fine.
Initialized with 2 partitions:
- 3GB MacOS Standard
- 3GB MacOS Extended
Ran disk First Aid - no problems.
* On a lark, I ran Disk First Aid on the Install CD and got the following:
Problem: Custom icon is missing,452,328
Problem: Custom icon is missing,453,327
Volume iMac Install needs to be repaired.
Began Installation again anyway...
Selected Clean Install from Select Destinations | Options
Recommended install.
Reboot. Address error. Same problem...

New iMAC. TRIED TO INSTALL LEOPARD. EJECTS CD. WON'T BOOT OFF INSTALL CD

WHAT A NIGHTMARE!New iMac came today-- with antique software. Tiger installed from factory-- and way out of date. Leopard DVD included in box-- tried to install- just keeps ejecting the CD when trying to do the reboot. 2.5 hours on the phone with overseas Apple support (ha!)-- machine will not boot from install CD's (either Leopard or Tiger). Keeps ejecting the cd.
What crap. ANybody else have this problem? I bought a mac because I didn't want to fight sw issues. Boy was this a mistake.
Any advice appreciated, or I'm sending the POS back to Apple get a refund and buy a Dell.

what would you think of ordering a machine based on seeing it demoed with Leopard-- only to have it shipped from the factory in China with Tiger-- and first thing it does is look for softwre updates-- and find over 150MB of updates it wants to install-- -within its first 15 minutes of being powered up????
If that's not shipping a machine with old software- I don't know what is.
What's the fuss about apple anyway? Shipping machines that don't have current sw loaded, won't boot from install DVDs, and then tell the customer that it will take two weeks to replace the unit-- or I can drive to an APple store (with gas at 3.25 a gallon which is an hour away) and maybe they can fix it, but not sure if the parts are available?
Has anybody else had this problem?
I would ask for a new machine with Leopard pre-installed which is what you expected to get and paid for. I can only assume it's an older machine since the new ones do come with Leopard installed.
My opinion, for what it's worth is to return it and ask for the new Leopard version.

Very slow boot after installing 10.10.3

insanely slow boot after installing 10.10.3, it takes 10times longer compare to 10.10.2, using MBA 2014

Open System Preferences, select Startup Disk, and make sure your internal drive is selected as the startup disk. Then click restart!
This worked for me, personally with the same issue.
Good luck!
