MBP won't boot after crashing while installing OSX

Hi
My 2010 15" Macbook Pro crashed while installing Mountian Lion. This was clean install, I had earlier in the process formatted the harddrive.
I have browsed the forum for similar problems, but neither holding down cmd+ctrl+r+p, cmd+r nor just the option key on start-up gives me anything but black screen.
To avoid confusion I am sure that the computer is starting as I can hear the fans starting.
I hope very much to receive input, thank you

Start all over with 10.6, make sure to erase the ENTIRE drive in 10.6's disk utility
use the security option > zero as instructed

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear.

MacBook Pro won't boot after trying to install 10.7.3 update. Start up stalls at Apple logo and spinning gear. Computer won't even start in safe mode.

My daughter's MacBook Pro was doing exactly the same thing. I don't know if it had anything to do with the latest update. She called me about a week ago saying that her MacBook began running slower by the day . She then called me Friday and told me that it wouldn't get past the gray screen and the gear just kept on spinning. I did everything I could over the phone including Safe mode which it wouldn't go into and thought maybe it was the hard drive. She took it to the Apple store. Originally, they also thought it was the hard drive. It ended up being a corrupted operating system (Lion). Apple genius simply re-installed Lion and she's back up and running. Good thing she backed up right before it crapped out. She'll be restoring everything tonight. Don't know if re-installing Lion will help your situation, but it did the trick for my daughter.

Z580 won't boot after Windows 7 Install

Hi,
After a clean install of windows 7 on the hard drive, Lenovo Z580 wont boot up but when hard drive it put into my old Acer laptop, boots fine.
Initially had to remove the hard drive from the Lenovo and put into another laptop to install windows 7 as lenovo wouldnt boot from usb or CD. And then after install tried putting hard drive back into Lenovo and just doesn't boot at all. Just goes to boot manager sceen and then blank in a continous loop.
Please help!
Thanks in advance!

Welcome to the forum!
"remove the hard drive from the Lenovo and put into another laptop to install windows "
You stated the exact reason for your problem. You can't install Windows 7 on one laptop and expect it run on another by swapping the hard drive. It doesn't work. During the installation Windows inventories the installed hardware and configures itself accordingly. Since they are two different machines, Windows won't boot. You are going to have to resolve the USB or Optical drive boot problem on the Lenovo laptop you wish to install Windows on.
During bootup have you tried using the Boot Menu to boot the machine specifically from the optical drive?

MBP won't boot after update!

I've got a late 2006 model. I'm hoping my problem isn't related to a hardware failure. I left it on during the day, came home, the fan was running hard and it was really hot. Performance was slow, but everything worked.
it was asking me to restart for the latest update anyway and I'd been putting it off for a day or two, so I decided to restart and let it go through with that.
But now, it won't boot. It starts up with the grey screen, a bar starts filling at the bottom, gets maybe 1/10th of the way, blinks out then another bar appears, starts filling, gets a little further, then the machine shuts off. Exact same process every time I start it.
I'm not really familiar with what my options are here.

No, that certainly isn't the issue! Just had to make sure.
If it's not a hardware issue which happened to coincide with the update, the update may be corrupted or not completed. If either is the case, and you have another Mac available, you can try downloading the update from Apple Support Downloads, booting the MBP into FireWire Target Disk Mode (if it will cooperate), and trying to install the update that way. I have not tried this method, so cannot say if it will work or not, but I would try it prior to the alternative, which is to reinstall the OS (or, better yet, clone a backup to the MBP).

Windows 7 Won't Boot After Nvidia Driver Installed, MSI Gaming N770

Hi I just bought the MSI Gaming N770 2gb and after installing the nvidia drivers, Windows 7 will not boot after my motherboard POSTs.
I bought this to replace an AMD card. I uninstalled all the AMD drivers before putting in the MSI card. I've also run the Display Driver Uninstaller in Safe Mode and everything.
After a few hours of research, I finally came across a thread about flashing a vbios, and something about these cards not working with motherboards with UEFI bios.
I'm using a P8Z77-I Deluxe mini-itx board, with a Rosewill 630W psu.
I have both 6+2 PCI pins plugged into the two 8pin power ports on the GPU.
Is this an issue that can be fixed with turning off secure boot? or by flashing a vbios onto the card? Or is the card a dud? Or do I have to re-install Windows.
If the vbios is required, are there instructions on how to flash it? I have no idea how to flash a BIOS. Thank you!!

Had to update BIOS. All fixed!!!!

Computer won't boot after windows 7 install.... :( [Solved]

I have 2 hard drives. The first drive is my main arch linux install. The second drive I use to install various operating systems. My school was selling windows7 for $30...I couldn't resist the cheap price...now I'm paying for it ><
I unplugged the hard drive with my arch linux install from my computer. (sda) Then installed windows 7 on the second hard drive. I reattached the first hard drive to my computer. (this was so i could avoid having to re-install grub)
My computer would not boot. I decided to install linux mint -- something I was going to do anyway -- that way I could boot into arch linux and fix things. Mint installed fine. But my computer STILL won't boot. I get grub error 22. What's up with that? Is this something to do with windows7?
Hard Drives:
/dev/sda1 ext2 /boot 100 MB
/dev/sda2 extended
/dev/sda5 ext3 arch / 130 GB
/dev/sda3 ext3 arch /home 166 GB
/dev/sda4 swap 1.72 GB
/dev/sdb1 ntfs windows7 65 GB
/dev/sdb4 ext3 mint / 19GB
/dev/sdb2 swap 1GB
/dev/sdb3 ext3 media 900 GB
Should I install grub to the MBR?
I checked to make sure that nothing in my arch linux install was erased using the arch install cd... I really need to get this fixed before classes on monday so any help would be appreciated.

I was going to say, even at $30 you still managed to get the full windows experience at first boot!
Meskarune wrote:PS. I heard that windows will override the MBR when it updates... so consequently it is bad to install grub to the MBR in a dual boot system. Will I have to be reinstalling grub all the time?
God i hope not. just stay away from windows if that happens
just thinking about tihs is giving me headaches.

Jaguar won't boot after iPod updater install

Greetings,
My Jaguar (10.2.8) will not boot after I installed (via Software Updater) the iPod Updater 2005-11-17 on my iMac.
I've run Repair Permissions and Repair Disk using Disk Utilities (from both a Jaguar and Panther install CD) and zapped PRAM (3x). No problems show up on Repair Disk. I get the start up chime and a gray screen with the gray Apple logo, but no spinning circle. That's as far as it goes. I cannot boot to Safe or Single-user mode (not sure what I can run except fsck -y).
I can, however, boot to OS 9.1.x on the hard disk; I'm hoping to copy/recover files over the newtwork.
Any ideas (short of erase/partitioning drive and reinstall OS)?
(Don't know if this has anything to do with my post- iPod Update 2005-11-17 problems, but. . . My original iMac drive was 4Gb. I Carbon Copy Cloned the whole disk to a formatted 30Gb hard drive mounted in an external USB drive enclosure, removed the larger drive from the enclosure and installed it in the iMac. Worked like a charm. I've used it this way for almost a year, enduring several application updates, e.g. security updates, QuickTime, iTunes, even one iPod updater. I have noticed, however, that I cannot reinstall Jaguar or install Panther to this HD because the system is not in the first 8Gb of the hard drive. Apparently, I need to create a partition on this 30Gb drive that is < 8Gb in size before I can proceed with the install/reinstall. I thought this limitation was corrected with Panther, but not so?)
Thanks,
Richard

Figured it out.
I couldn't boot to OS X because, it seems, the iPod updated caused Jaguar to behave in it's predictable pattern of not booting properly from a partition > 8Gb in size on this iMac (a 233Mh model that Apple says is affected in this way, http://docs.info.apple.com/article.html?artnum=106235). In my case, I had Carbon Copy Cloned my 10.2.8 to a 18Gb drive. No problems occurred with running it. However, this was the first set of updaters I've installed on that OS since that cloning operation. And it simply wouldn't boot.
I booted to OS 9, copied files to a laptop over the network, pulled out the Jaguar install disks and repartitioned the drive to include one partition <8Gb in size, installed the OS there. All's fine now, just have to hassle with moving all those files back and testing.
I could have used a repartitioner (FWB Partitioner Tool for OS 9, <a class="jive-link-external-small" href="http://">http://www.publishingperfection.com/fwb-software/fwb201/, other dynamic partitioners are available for OS X) to make the < 8Gb partition within my OS 9 boot and avoid deleting everything on the drive in the process. But I didn't figure this out until I'd already backed everything up. Plus, I didn't want to pay the extra bucks and wait for shipping. So I used Disk Utility on my Jaguar install disk to create my < 8Gb partition for Jaguar. Now I have a fresh install. But I'd rather not have had to spend the time figuring all this out!!

MBP won't boot after failed 10.4.9 install (stalls at grey screen)

MBP intel CD2 2.33 2GB RAM previous 10.4.8. attempted install of 10.4.9 Received an error stating 10.4.9 could not be installed. Restarted and now the grey screen with the small apple symbol and spinning wheel at startup just keeps going. It never reached the blue screen. I let it sit for at least an hour and still the same. Reboot and it does the same... stalls at the grey screen with apple symbol.
Any help or suggestions would be greatly appreciated. I looked through the support files and threads but could not find anything about this.
I don't have a backup (ouch) but will be doing that immediatley if I can get this fixed.
BTW.. I did attempt to boot from the install disk and it does show the boot folder on the HD as 10.4.9 although it said the install failed.
Thanks again
Chris

Thanks guys. I need to get a firewire>firewire cable. I'll boot into target mode and backup my home folder.
What about re-installing the OS with the option of preserving the previous settings and user account. Would I be able to access my old applications or just the files? I was considering reformatting anyway because of all the "crap" I've loaded on over the year.
Rregardless I will try target mode first and let you know.
Thanks!

Ultra 5 won't boot after Solaris 8 install

Hello. After installing Solaris 8 on an ultra 5, the system won't reboot. After trying many permutations of the install, including a bare minimum and the whole shebang, it became clear that the system always hung at the same spot in the boot process (from a boot -v), immediately following the line:
cpu0: SUNW, UltraSPARC IIi (upaid 0 impl 0x12 ver 0x13 clock 270 MHz)
Has anyone seen this problem before? We reset the boot PROM with set-defaults from the ok prompt and that made no difference. This machine ran fine under Solaris 7, so I don't think it's a hardware failure. Any suggestions would be greatly appreciated. Thanks!
--jenny

Can't be the OS if the disk doesn't show any activity.
I can't tell from your post if you're using a screen/keyboard or a serial console? Have you removed the keyboard and attached a serial terminal to serial port A? Several types of hardware failure will output errors there even if the failure occurs before the framebuffer is initialized (memory errors are common).

MBP Won't Boot After Upgraded to EFI 2.2

Hi,
I upgraded to the latest EFI 2.2 firmware yesterday. After the reboot, the computer hangs on a black screen with a fan noisy. I have tried to reset SMC and PRAM & NVRAM, but there is no luck. I even couldn't hear the startup sound. Does anyone have experienced the same issue? Is my motherboard broken? It would be very appreciated if someone could help me out. I'm really frustrated now.
Thank you.
Kai.

Server 8 Won't Boot After Hyper-V Install

I recently downloaded the Windows Server 8 beta, I wanted to play with Hyper-V. I setup a second partition on my i7 at home and loaded it up. The installation was clean without any issues. After starting up the server (in both full GUI
and a reload in Core) I am unable to get Hyper-V to work. I will complete the full Hyper-V role installation and the system will reboot, and then hang. I have tried this from full GUI and from a Core installation. I have verified that my
i7 has EPT (SLAT) and I have all the virtualization enabled in the BIOS. I have tried to do a bit of recovery on my install but I never am able to get very far. I have wiped the drive, and reloaded a total of 3 times and had the exact same outcome
every time; lock up on reboot after installation. I thought maybe it just needed some extra time to sort out the added role and just let it go overnight. In the morning it was still locked up on the reboot. To be more specific, it is at the
point where I have the fish on the screen and the dots going around in a circle (until it freezes).
I want to add that I have also tried a 'pure' beta without updates and also tried updating before hand. Same results. I have done a bit of research on this issue and I am confident my machine meets the minimum requirements. i7-950 with
12GB of RAM.
Has anyone else experienced this?

If you have the Z68MA-D2H-B3 board, go here and get the UEFI update.
http://www.gigabyte.us/products/product-page.aspx?pid=3975#bios
UEFI is the BIOS replacement. Once that is done you can use USB 3.0 with Win8 and Hyper-V. Oh, and the computer boots about twice as fast. At least that was my experience. There is a list of Gigabyte utilities that need to be removed first, so read
the instructions well.
"(Note) Some GIGABYTE utilities are not supported under UEFI BIOS architecture. Please remove Smart6, Dynamic Energy Saver, Smart TPM, and Touch BIOS utilities before updating the BIOS."
I used a FreeDOS bootable USB to apply the update, since you can't do it from inside Windows or through the BIOS updater.
http://rufus.akeo.ie/
You may need a clean re-install Win8 afterwards. I did it out of habit, so I don't know if it will pick up the changes and work without it. Back your stuff up first just in case you do.

MBP won't boot after resetting SMC for being stuck in sleep.

Last night I closed the lid and put my mbp into sleep. Today my mbp was stuck in sleep with the light stuck on and the battery indicators were not functional so I reset the smc. This fixed the stuck in sleep problem but now it will not boot at all.
Any help is appreciated.

Win 7 won't boot after successful (?) install

Hi Group,
Tried searching the forums for this problem and found similar postings but I think my problem is different...
I've successfuly installed Win 7 Ultimate x86 in that I get to the point of entering product key, etc. but when it does the final reboot I just get a blank screen with a blinking cursor. Tried some of the workarounds like clearing the pram/smc, deleting the ati driver .sys file (which doesn't seem to exist actually) and also using the driver autounattend from the usb drive. I'm running the latest version of boot camp.
Not sure what to try next. I've been successful installing this version of windows in VMWare and on a fujitsu-siemens laptop without any issues. I've also been successful at installing Xp via bootcamp. Really at a loss as to what to try next. Any help would be greatly appreciated.
Cheers,
Jeff

*Take an iMac and Windows 7 Blue screen fun*
the final part of the Win 7 install and Mr Blue screen due to the Nividia driver supplied on Win 7 DVD kills iMac GT7300
1. Install... and Blue screen!
2.Re-boot but from the Win 7 install disk – seems to work if you hold alt on boot up and select the disk to boot from!
3.When you get into the Windows installer, click past the language selection. Then click "Repair your computer".
4.Windows will scan for installations and prompt you with a list. Select your "C" drive and click Next.
5.You should be presented with a windows titled *System Recovery Options*.
At the bottom of this list you should see +Command Prompt+.
Select the command prompt.
6.When the console opens, you can delete the offending driver using the following command:
DEL C:\WINDOWS\SYSTEM32\DRIVERS\NVLDDMKM.SYS
7.Close the command prompt window and click the Restart button.
This time, boot from your hard disk.
You will complete the install with no Blue screen.
Having done this go to the Nivida web site and download the GT 7 series drivers for Windows 7.
Install, re-boot and ...
+*... install Bootcamp drivers and right off your back to Blue Screen...*+
Repeat 1-7 and install newly downloaded drivers and off you go

MBP won't boot - "GRUB_" - tried installing ubuntu on an external drive

so i tried installing ubuntu netbook remix onto an external drive, and upon restarting my MBP won't boot to my internal HDD, once it displayed "GRUB_" with a blinking cursor, but is otherwise unresponsive.
now i just get the folder with the ? on it.
I've run disk util, repair permission, repair disk and still no luck.
i can boot the MBP into target disk mode and see the HDD on my other system and all appears to be good, and if i boot to the install dvd, the HDD shows up under the "startup disk" menu, but it just doesn't boot.
any thoughts on how to fix this?

So I have an imac that I have had for about 3yrs. About several months ago, it started acting a little strange, it wouldnt pick up the mouse or the keyboard at times even thought they were plugged in properly to the usb port, sometimes both would work sometimes one or the other would work and other times they worked fine. About a month or 2 ago, I went to turn my imac on and it got to the screen where the little circular icon pops up implying it is loading, stayed that way for 2-3min then turned of and turned itself back on and did the same thing, made the apple sound got to the load screen turned of after 2-3min then turned back on, it has been doing that for the past month. What do I do?
