Re-booting to mac osx

I've installed windows 7 and to get my bluetooth keyboard and mouse to work, I had to remove them from bluetooth settings on Mac OSX. Everything is working fine in Win 7, however, I now can't re-boot into mac since the keyboard isn't recognized at start up, so I can't press the option key. Is there another way to bring up my boot options?

I've installed to bootcamp drivers with the Snow Leopard disk, but there is no option to click on start up disk. Did a driver get missed? Should I rerun the bootcamp install with the Snow Leopard disk?

Macbook pro will not boot into Mac OSX

When i got my MacBook Pro it would boot into Mac OSX fine. Now it wont even give me the option and will only let me boot into Windows which i have running through bootcamp. I have tried reinstalling MacOSX but my OSX installion DVD will not get recognised and i cannot boot off it either. I have tried using 2 other discs still with the same issue. The confusing thing is that the CD/DVD drive works fine and the MacOSx discs work fine in other macs as i have tried it in my brothers machine.
Any help appreciated.
Thanks

I don't think that the laptop even has Mac installed anymore becuase in an attempt to reinstall Mac the partition was formatted. And I can't boot of the disc becuase it just ejects by itself after a few seconds in the drive.

Can't boot to Mac osx, Error -2100F

Hi there,
I got a Macbook Pro Retina Late 2012, and I made a dual boot to Windows 7 today.
The problem is when I try to boot to Mac osx it automaticly start up as Windows 7.
I tried to use the Command key to get the Mac osx running and the only boot that I see is Windows 7.
After that i tried using Command + R to recover it and it gave me an error -2100F.
I also tried to use Boot Camp to Boot to Mac but that also goes straight to Windows.
My guess is that I deleted the wrong partition when I installed Windows 7 and that i am unable to boot to Mac osx now.
Can anyone help me fix the problem?
Thanks in Advance

Use your backup(s). Erase and restore.
Also XP is not being actively supported.
With OS X upgrades you always need to check and make sure you have the latest, like Parallels 7, or there is VirtualBox 4.x
Sounds like you simply had a corrupt hard drive.
Lion 10.7 will only support Windows 7 except in a VM.

Booting from Mac OSX Instead of Windows

Hey, I'm wondering if anyone could help me with a very minor but irritating problem I've been having. I installed "Bootcamp" and ran the program to partition my drive and run windows. It worked perfectly, but the only problem is now my iMac boots directly from Windows as soon as I restart or startup my computer. I would much rather it boot straight to OSX so that I could avoid pressing the "option" key continually on startup and restart.
Thanks

In OS X, go to System Preferences > Startup Disk and select Mac OS X.
You can do the same thing in Windows by going to Control Panel > Startup Disk.

Slow boot time Mac Osx when USB external hard drive is connected

I have bought some days ago an external hard drive, the Western Digital 500 GB Elements.
It goes very well by now but I have a problem.
When I turn on my MBP, after the "bong", I have to wait 60 second more than the normal boot time.
The screen stay grey and after 60 second it appears the apple.
It appens only when the external hdd is connected.
Someone has a solution?

Some time ago, I read that the OS has a problem waking from sleep or booting if an external was attached (USB or Firewire), something about it being confused about the startup order. Anyway, since then, I have religiously followed this procedure when I'm done using the external: unmount, unplug, and then turn it off (if necessary). I have never experienced a problem with my Mac not recognizing or not being able to boot because of an external. It certainly doesn't involve more than a second or two to unplug a USB drive.

Imac with 3Gb fusion drive "no bootable device--insert boot disk and press any key. This started over the past 2 weeks, and now occurs every day. Initial boot to MAC OSX is Ok.

I receive the above black screen 'no bootable device' error message daily, after not using my imac for a while. I will note that the computer will boot normally, and after a while, the screen saver initiates. Some time later, I get the black screen error message. I have to hard boot the computer again at this time. Any ideas?
Thanks for your help,
JTH

That message means that your Mac restarted and that no bootable volumes were found. First, open System Preferences > Startup Disk, and choose Macintosh HD. Then, see if the problem appears.
Also, open Disk Utility, choose Macintosh HD in the sidebar and verify it. This may be a sign of a hard drive failure

SYSTEM CRASHED BOOTED INTO MAC OSX BASE SYSTEM WEBKIT HELP!!!!

MY SYSTEM CRASHED AFTER AN UPDATE. RAN A BACK TRACE LOG BECAUSE A GREY SCREEN BOOTED UP WITH ONLY SAFARI INSIDE. BACK TRACE LOG SHOWED A WEBKIT SAFARI OS X INSTALLED AND HAVE PERMISSIONS OVER MY STARTUP DISK REPLACING IT WITH THEIR "MAC BASE OS X SYSTEM" AS WELL AS MY RECOVERY HD TOO. HOWEVER I AM ABLE TO GET INTO DISK UTIL AND REPAIRED MY HD AND RECOVERY HD HOWEVER THE OTHER IS STILL THERE AND WILL NOT LET ME ERASE IT. IT STATES IN INFO OF THE DRIVE "NOT ALLOW OWNERS TO TURN OFF...YES". I AM IN THE SAFARI BROWSER NOW AFTER LEAVING DISK UTIL. DISK UTIL READ MY HD IS FIXED AND OK AND WILL BOOT HOWEVER I AM SCARED IT WILL ONLY BOOT INTO WHATEVER THIS WEBKIT MAC OS X BASE IS.

That's Mt. Lion's Recovery volume which you could have used to erase the working volume and do a clean install of Mt. LIon. To get rid of it you may have to try to repartition the entire drive with Disk Utility.
Otherwise, reboot with the Command+R keys held down to boot into the Recovery volume. Once there run Disk Utility to again erase the working volume and then do an install of Mt. Lion. This method is much easier and quicker than doing it from the USB device.

Cannot access boot from Mac OSX install Disc-frozen cursor

Twice a month I do some housekeeping and clean up my Mac--run scripts, verify preferences, repair permissions, etc. Quarterly I boot from the installation disc to renew any start up info that may have become corrupted.
My IMACG5 won't allow me to do this now. I put the disc in, and shut down the machine. I start it up again while holding down the C key but when it is finished booting from the disc my mouse cursor is frozen on the screen and I cannot acess anything. I have a battery operated mouse and I always check to make sure there is sufficient battery life.
Does anyone have any suggestions as to what is up and how I resolve this issue? At this point I won't be able to wipe my hard drive and re-boot everything fresh from my installaion discs because the cursor is frozen.
IMACG5 Mac OS X (10.3.9) wireless keyboard and mouse

Hello jaqueline & Welcome to Apple discussions
I put the disc in, and shut down the machine.I start it up again while holding down the C key but when it is finished booting from the disc my mouse cursor is frozen on the screen and I cannot acess anything.
I hope you mean Restart and not Shut Down.
Insert CD, under Apple drop down menu -> restart after/ at the chime hold the c key dowm till the gear/ wheel stops spinning .

Can't boot from Mac OSX CD.

Hi, i wanted to do a fresh install of snow leopard on my MBP, but when i try to boot from the snow leopard disk, it just hangs at a white screen with a grey apple logo on it. Ive tried install it from my desktop, it finished but absolutely nothing happened. Ive also tried booting while pressing option, and while pressing c.
I also want to use disk utility from the installation disk to repair my Macintosh HD. But i cant get into the cd..
oh yeah and while i tried to install it from my desktop, there was this button on the left bottom corner called Utilities. I pressed it thinking that disk utility was there and it told me to boot into the disk. I pressed restart and the same thing happened. it just hangs at the white screen with the grey apple logo. nothing else. and i also hear the disk stop spinning.
any ideas???

Maybe you killed your boot drive.
Normally you should of course be able to boot from SL DVD and instead of INSTALL go to menu bar and UTILITIES and select DISK UTILITY.
ZAP the PRAM will result in the "?" because the boot volume setting is no longer present. You can reset that also from SL DVD Utility / Startup Disk
My methods:
Clone and have a bootable backup first, DU Restore; or SuperDuper
Run utilities from there, like Disk Warrior
Even though you are suppose to be able to install from desktop, SL also needs to "prepare disk" (update partition table) and it is safer and really really adviseable to do repair from the DVD, as with any upgrade have a couple backups in place first.

Why is my mac always booting into Mac OSX Utilities?

Then I have to restart and then it boots normally.
thanks

I checked. Yes, Resume will cause Disk Utility to start upon restart under the condition I mention above. if you don't want windows open when shutting down to reopen upon restart, then uncheck the "Reopen windows when logging back in" box that appears after you chose to shut down.

Macbook won't boot to Mac OSX but will boot to Win XP after crash

My Macbook froze this afternoon so I held down the power button for 10 seconds and it went off. I turned it on and I get the gray screen of death (power off and restart, etc.). I did many times and nothing happened. I also, did the PRAM reset and NRAM reset, etc. . . I tried to boot from the install cd and I get the same gray screen after 2 mins or so (pressing command-c).
It will boot fine into Win XP via bootcamp so it appears that the hardware is fine?
Help!

Nope - doesn't work. I even can hold the option key down to see all my boot options - MacOS, WinXP, and Install CD. I select the cd and it runs for 2-3 minutes and then crashes with the same error screen.

PCI-Express Card for SSD that boots Mac OSX?

I'm thinking about upgrading my 2008 Mac Pro with an SSD boot drive, but I want to get the maximum speed out of the SSD. Since many of the SSDs have a SATA III interface capable of 6Gb/s, I'd also like to get an internal controller that will allow me to boot into Mac OSX. Which card do you reccommend?
Also, is there anyway to place the SSD in the lower optical drive bay of the Mac Pro? If so, what will I need to do that?
Thanks!

The only way to get greater than effective speed on the sata2 connection is to raid the ssd's. Otherwise you are stuck with sata2 speeds.
Here's a thread on sata3 pci cards in these disccussions:
PCIe card to enable bootable SATA3 SSD on early 2008 mac pro?
If you want to do some research in other places there are many hits on this topic when you google "sata3 pci card for mac pro".
Also, I just recently became aware of a new pci card that OWC announced which they call Accelsior™. It's not cheap, even for a 120GB drive.
OWC 120GB Mercury Accelsior™
Here's MacPerformanceGuilds' review of it.
Basically it's a ssd on a pci card thus limited to the pci speed and not the sata speed. Looks cool.

Mac OSx Imaging questions

Hello everyone,
I have a couple of questions I'm sort of confused on. What I want to do is basically create an entire image of a hard drive and then deploy it later if the hard disk starts to fail. I've read the forums suggesting CCC and Superduper to clone hard disks using firewire. I have two Mac G5 and two intel macbooks. Unfortunately, the macbooks do not have a firewire port. One of myMac G5 10.5 is setup with a Raid 1 (mirrored) which I would like to use as a backup server for images. Is there an application similar to Ghost that can just create images of a macbook, macbook pro, mac pro or G5 in a compressed format to a server (G5 Mirrored)? I've notice a video of where a guy has several dmg files on his external hard drive, but then he restores them by booting the Mac OSx DVD on the destination mac and then restoring them through disk utility. First, how would I go about creating those bootable images to my G5 raided 1 (mirrored)?
Reference Link: http://www.youtube.com/watch?v=5iWYBv5L_oY
Notice at 3:17 that he has multiple dmg. How would I go about creating several dmg for a macbook, macbook pro, mac mini for later restoration. I can actually just back those up on my G5 PC for backup, but later restore them if I need to.
Thanks for all the help.

Please do not use disc images for backups. They are a poor choice for backup. Better to clone your boot drives to an external using the Restore option in Disk Utility. For your MacBooks without Firewire use USB instead. Your Intel Macs require different drive partitioning than your PPC drives, so you need separate backup drives - two USB for the MacBooks and two Firewire for the G5s.
The Intel drives must be partitioned using GUID, while the G5s' drives are partitioned using APM. All are formatted Mac OS Extended, Journaled.
Once you make the bootable clone with Disk Utility you can maintain them by incrementally backing up changes using a utility like Carbon Copy Cloner or the licensed version of SuperDuper!.

Mac OSX will not boot, when I log in, it shuts down after grey screen and grey loading bar show up: PLEASE HELP (:

So here is a lowdown on my problem.
I start my mac OSX, I hold down the alt/option key and load my MAC osx drive (which is the only drive available; however, when i do not hold down the alt/option key it will go to a black screen that says "no bootable device, press a key when device inserted"). Continuing, it then goes to my login screen where I have my username, and I can enter my password like usual. I enter my password, hit the enter button (like I always do), and this is where my problem begins.
After I enter my login and hit enter, the screen goes grey, with a little apple symbol in the middle and a different shade of grey loading bar underneath. This grey loading bar shows up for about 10 seconds, fills up about 10-20 percent, and then shuts my computer down.
No matter what I do, this process repeats over and over, and heres where the problem gets worse, and this part is VERY IMPORTANT and is the most depressing, stressful part of the process.
NONE of the startup/boot commands work except holding the alt/option key. I can't hold: Command plus r; command pr to reset PRAM; shift to enter safe mode.
I really dont know what to do here :/. I have files that I want on the hard drive, that are pretty important but not critical. I gave up on wanting the files back but now I want to simply WIPE my computer and re-install a clean version of OSX onto the computer, but I CANNOT GET TO THE REINSTALLER :(.
More information that may be helpful:
          I do have a partition on the HDD that I was going to use for Bootcamp, but it does not have anything installed on it (thus causing the "no bootable device" screen to load, and probably causing the boot commands not to work).
          My version of Mac OSX is 10.8.4. "MBP 15.4/2.8/16GB/768 flash"
          The last time I restarted my computer, my mac OSX RAM was down to 1.75 GB, with nothing open. Usually when nothing is open the free RAM is around 10-13 GB (I know this because I have the activity monitor always open, and I use my computer a lot).
          Again, boot commands will not work, except for holding the alt/option key.
So if anyone can help me fix my problem(s), which are:
1: using boot commands; 2: reinstalling mac OSX; or 3: getting my files,
I would love you forever. I would really prefer 1 or 2. Thanks for reading this.

Oh and one more thing, I do not have a disc drive in the mac osx. The version I have comes without one.
I am very puzzled about what to do right now.
