Kernel Panic, but I can still boot into windows? :(

Hi folks,
2007?'ish MBP 2.2
machine (normally) boots right in to SL (latest rev).
holding option, I can choose SL or Windows XP.
I have a firmware password set up (i know the password if i need it)
the problem: when i turn my mac on, it will not boot into Mac right away. I get an error that it's "unable to find driver for this platform: \ "ACPI\".\n"@/SourceCache/xnu/xnu-1486.2.11/iokit/Kernel/IOPlatformExpert.cpp.:1 389
there's more, but I won't type it just yet b/c I just thought of a possible reason:
I was reviewing photos with a client for a slideshow (everything is backed up..no worries) and she had a thumb drive with more photos. I plugged it in the USB, but it wouldn't read or open in finder.
No worries - I ran downstairs to my mac pro, it worked. Dragged the pics off.
Shut down my macbook pro b/c I wasn't using it and when I tried to turn it on later, this problem is there.
What I've tried:
resetting SMC
resetting PRAM
can't do the TDM - read the article about needing to install the software to open passwords, but hard to do if the computer is down (unless they mean installing it on the machine from which I'm trying to access it?)
i tried holding option to key in my firmware password, but the same thing happens - can't access the Mac side of things. I can access the Windows section and as I'm typing this, it looks like I'm able to access the install disc
Just thought I would post this for 2 reasons:
1. to see if there's anything else I can do (I am going to try disk utilities to repair the disc)
and 2. to help anyone else out in case they have the same issue.
Cheers,
Keebler

Backup what you can, boot from a compatible installer DVD, erase the hard drive, then reinstall OS X.
Alternatively, you can try the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
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 Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

  • Pavilion G6-1203ey: Hard Disk Test FAILED, but can still boot into Windows

    Hello
    I have HP Pavilion G6-1203ey laptop. After installing Windows (7 ultimate, 64 bit) and some drivers on it and after several restarts, it hanged at Windows logo and I had to turn it off with power button. Then after turning it on, it gave me the option to repair problems which are preventing it from starting up, from there I let it to restore the computer to an earlier restore point and after a restart the Windows was working again. After that I decided to do a hard disk check just in case.
    The Hard Disk Self Test ended up with a message: Hard Disk 1 Full (305). Then I installed HP Unified Extensible Firmware Interface (UEFI) Support Environment and did hard disk from there. I chose the comprehensive test from the options, but it finished fairly quickly (in ~1 minute) with the following output:
    Testing Drive: 1
    Hard Disk SMART Check : PASSED
    Hard Disk Short DST : FAILED
    FAILURE ID : PTTU22-5T774L-MFPV4K-60S003
    PRODUCT ID : A5Q15EA#B1R
    Hard Disk 1
    Hard Disk Test : FAILED
    A bit more background:
    The previous owner told me that the original HDD was faulty which is why he replaced it with this one last year. He said that other than that there has been no problems with the laptop. The Windows is working right now and this HDD is quite new so I would not have expected any problems with it, but the results from the previously mentioned tests seem troubling. Is there a reason to worry?
    Thanks

    I read your post and looked into the failure ID that you posted regarding the failed Short DST test. That error is indicating a hard disk failure meaning that if it hasn't failed it might soon. If everything is working I would considering backing up your data on a regular basis just to be safe. You could have a local technician take a look at the hard drive to see how close it is to full failure.

  • Can't boot into Windows 8.1 partition after apple store repair

    Can't boot into Windows 8.1 partition after apple store repair
    I went to the apple store about a week ago to get my screen fixed, and when I get it back I don't have an option to boot into my windows partition. The bootcamp partition is still there, but I can't boot into it. I can still see all of the files on the drive. When I try to boot into windows from the startup disc setting I get "no bootable device — insert boot disk and press any key” on a black screen. I went in for a dead pixel, and the guy at the genius bar ran something on my computer and went into disk utility application. I’m not sure what he was doing, but obviously that’s what messed up my windows partition. How can I be able to boot back into windows? Here's what disk utility looks like on my computer.

    Here's the output

    Here's a better screenshot.

  • Can I boot into Windows XP from a firewire enclosed Hard Drive? Boot Camp

    I understand you can install XP (as long as it has service pack 2 or 3) on an Intel Mac using Boot Camp, but I was wondering if it would be possible to take a HD from a PC computer which already has XP installed, and, using an firewire HD enclosure, boot the Mac into XP from that. Would this be feasible?

    Yes, but not exactly. The page says:
    "Can I install Windows on an external drive?
    No. Installing Boot Camp on an external hard drive is not supported."
    But I don't want to install Windows, I want to boot my computer into it.
    It also says:
    "External FireWire disks are not recognized by the Startup Disk control panel in Microsoft Windows. To start up from a bootable external drive, press and hold the Option (Alt) key while the computer starts up, then select the external disk."
    I don't mind if external disks won't appear under Windows, as long as I can still boot into it.
    I found another helpful post:bootcamp windows 7 Firewire external drive NTFS?
    Here someone writes:
    "I still use Windows XP with my Mac but still never had such a problem with my two Firewire external HDs (one FW400 and one FW800).
    And I did a lot of things with these
    Partioned one for use with OSX and Windows (one HFS+ partition; one NTFS partition); copied my complete MP3-collection (180GB) from one external HD to the other; etc.
    All without any kind of glitch or slowdown."
    So it seems this person was successful in booting XP from an external drive. Windows 7 or Vista on the other hand will encounter problems booting, which that tread explains.
    In another thread (Boot camp on an external hard drive) someone wrote:
    "I believe there might be a way, I just haven't gotten around to trying this out.
    1) use disk utility to partition the external drive to ntfs (i think)
    2) attach this disk to a pc and install the OS
    3) install refit onto your mac
    4) attach the drive via fw800, or even better yet esata, to you mac.
    5) Start up your mac
    6) choose the win xp option from the boot menu
    7) install bootcamp drivers
    this seems, in theory, that it should work."
    So from what I gather, I think this method would probably work, I just want to know if anyone had any specific knowledge regarding this subject.
    From here I only have two questions:
    Is it possible to take a working drive from a PC which already has XP installed, and change the format to ntfs under OSX without damaging the drive or OS?
    And, would I need a version of XP with service pack 2 or 3, or will anything do, since we are not installing it with Bootcamp, we are only running it under Bootcamp at this point.
    Thanks for any help!

  • Hi, can anyone help with the problem I am having with pro book 4440s? I can't boot into windows 7.

    Hi,
    If you don't already have one, use another PC to create a Windows 7 Rescue CD.  Download the relevant ISO from the links below.
    Windows 7 32bit
    Windows 7 64bit
    You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here.  Once created, or if you already have this, tap away at the esc key as you start the notebook to enter the Start-up Menu.  Insert the Rescue CD.  Select Boot options ( usually f9 ), use the arrow keys to select the CD/DVD drive and hit enter.  You may also get a prompt to 'Press any key to continue' - do this if asked.
    When loaded, select Repair Your Computer and choose the Command Prompt.  When this loads, enter the following commands and hit enter after each one - include spaces as shown.
    Bootrec.exe
    bcdedit /export C:\BCD_Backup
    c:
    cd boot
    attrib bcd -s -h -r
    ren c:\boot\bcd bcd.old
    bootrec /RebuildBcd
    bootrec /fixmbr
    bootrec /fixboot
    Remove the Rescue CD and try rebooting the notebook.

  • Can't boot into windows 7 anymore......

    Hi all, I have a Mac mini late 2012 with windows7 installed through bootcamp5. It has worked flawless until recently, now I can't boot into windows anymore. I've checked in finder and the bootcamp partition is present and also all the files. Before that, I did have some trouble with my LaCie 2big thunderbolt hdd, it kept on saying I had to reformat one of the discs in the drive, but only when used in windows, in OSX there was/are no problems reading the hdd .......
    Any idea of how I can make windows bootable again?, do I really have to make a fresh install of windows to make it work??
    Any help is very much appreciated
    Kindly

  • Can only boot into Windows 7. Can't even boot from Snow Leopard DVD.

    I have no idea what prompted this. I don't recall installing any OS updates recently, other than some Windows Live apps in Windows 7.
    I have an early 2009 Mac Mini with Snow Leopard, and have Windows 7 64-bit installed in a Boot Camp partition. When I installed Windows 7, I couldn't get the Boot Camp utility to install within Windows (I guess because it's 64-bit) so to switch back and forth between OSes, I just shut down the Mac and restart it with the Option key pressed, and select Mac OS X when I want to return to Mac. This has worked for about a month and a half now (ever since I got Windows 7). Suddenly I have problems.
    I first had problems booting into Windows or Mac. I got to the grey screen with the Apple logo, with that spinning "progress" thing going for a while, then it would freeze up and get stuck on the grey screen with the Apple logo. I zapped the PRAM. No help. Then, after disconnecting all external drives (I have several) and extra USB devices, I was able to boot from the DVD install disk and reinstall Snow Leopard on my internal drive. Joy, or so I thought. Then I booted into Windows 7, and after some weirdness getting it to start, it did successfully start and ran just peachy.
    Then I turned off the Mac and held down the option key (as usual) to return to Mac OS. But now all that happens is that I get a grey screen for a few seconds, then the Mac boots back into Windows 7, which seems to work fine. (I'm in Windows 7 right now.) I turned on one my external drives (Snow Leopard installed, connected via Firewire 800) in hopes that the Mac would boot into that, but same thing. Ignored and back to Windows 7.
    Then I thought I'd boot from the install DVD again by putting it in the drive and holding down the C key as I restart, but the same thing--a grey screen for a few seconds, and then booting right into Windows 7. I can't seem to escape Windows 7! It's a bit disturbing when it won't even recognize the install DVD.
    I tried to call Apple Care since I'm within my 90 day support window, but of course they are closed. I'm figuring that I'm going to have to take this into an Apple Store, but thought I'd see if anyone has any ideas. Any advice will be appreciated. Thanks.

    According to Apple, Win 7 64bit is supported with Bootcamp 3.0. If bootcamp 3.0 is available; I could not find it anywhere on Apple's website. It appears the most recent version is 2.2. The only place I could find 3.0 is not on Apples website and it's a questionable source so I won't post it here.
    It may just be a matter of time before Apple makes it available. I'm not suggesting you wait, however if the install disk can't be used, I'm not too sure where u could go from there. Calling Applecare might work.
    If you do a simple google search using the terms 'download bootcamp drivers windows 7' u will see what I was referring too.
    Here's what I found from Apple (It doesn't specifically mention 64bit however just win7): http://support.apple.com/kb/HT3920
    This is not from Apple, but specifically addresses whether they support win7 64bit: http://www.macnn.com/articles/09/08/31/boot.camp.win.7.64.support/
    Here is more info about bootcamp 3.0 and win7: http://www.apple.com/support/bootcamp/

  • Can't boot into Windows??

    Hi!! This is my theory about not being able to boot into windows. If you have made a system repair disc like you should have made on day one; and your PC will not boot with the system repair CD, you probably have some serious hardware problems.
    I'm going to steal this reply from cee64 again. A system repair CD can be made from any PC that is running W7 ect.
    Hi I'm going to steal this reply from cee64. I'm sure he won't mind!
    "It is quite possibly the hard drive is failing or has failed.  The reason you can't get into the bios or boot from a CD/DVD is because the bios it hanging trying to recognize the hard drive.  Try removing the hard drive and see if it will allow you into the bios or boot to a CD/DVD.  If it does, go the hard drive manufacturer's support site, downlod their hard drive diagnostic ISO image, then use the burn from image option to create the self booting cd, then boot to it and run the most exhaustive diagnosis on it if it will boot.  If you can't get it to boot to the diagnostic disk while the hard drive is installed you'll more than likely need to replace the hard drive. 
    If it won't get you into the bios or boot to a CD/DVD with the hard drive out of the system you need to try reseating the ram.  If that doesn't help you probably have a bad motherboard.  In this case it would more than likely be cheaper to just replace the laptop than fix it."
    http://www.dummies.com/how-to/content/how-to-use-a-system-repair-disc-to-restore-windows.html
    If Seatools found your HD good, then you have a good chance of using the recovery disks or the recovery partion to restore you back to factory setting. If that fails, you may be down to a bad motherboard. I know of no program to test the MB. You can use memtest 86 to test your Ram. I think it tests some parts of your MB, but can't say that for sure.

    Hi! I stole this reply from Jerry Edited One link, because it failed to open
    Let's start here. The spec above says your machine came with 32-bit Windows Vista. Have you changed it?
    We need to reach the recovery environment. Can you do it this way?

    If not, burn a system repair disc from this download (assuming 32-bit Windows).
       Download Windows Vista Recovery Environment ISO X86 version (32 bit)

  • Can I boot into Windows if it is partitioned on a second hard drive?

    I want to put my 2009 MBP hard drive into a 2012 MBP by replacing the optical drive with the 2009 hard drive in a caddy. The 2009 has Windows partitioned on it already through bootcamp.
    Will I be able to boot into windows through the second drive or will I have to bootcamp the new 2012 drive with Windows?

    OK Cool.   I think I will try that.   Thanks for the tip.  I appreciate it.

  • Can't boot into Windows after splitting Mac partition with Disk Utility

    Hi everyone,
    I installed Windows 8 with BOOTCAMP, creating a large 871 GB partition with a smaller 127 GB partition for Windows. After installing Windows, I then went back to Disk Utility to shrink the Mac partition and add two new partitions, one for storage and another blank, hoping to use it to install Linux into one day.
    I did that, and now Windows doesn't boot. A Windows blue screen tells me I need to use the Windows DVD to repair it.
    I tried to use Disk Utility to delete the two new partitions I made and grow the Mac partition back to the max size of 871 GB. But it doesn't let me do this. The Disk Utility log doesn't report an error and thinks it worked but the partition stays the same size. However if I make the partition a little smaller, like 870 GB then it works. I'm wondering if the Recovery partition is hiding there and preventing me from fully expanding the Mac partition.
    What can I do?

    Kappy,
    I can boot into OS X just fine so if possible, I'd like to avoid reformatting everything. If you know of a way I can add more than 2 partitions with OS X and Boot Camp, please let me know. As far as I know, rEFInd can recognize more than two partitions, but I don't think it can edit partitions on a GPT / hybrid MBR system. Or am I wrong?

  • Can't boot into Windows 8 Single Language 64 bit or access the BIOS screen with the F1 key

    I have in my possession right now a Lenovo E49, Model name: 3464
    I am unable to access the BIOS settings at POST by pressing the F1 key.  Neither does it respond to the Enter key when it displays the message "To interrupt normal startup, Press Enter".  I am also unable to boot into the installed OS Windows 8 Single Language 64 bit.
    For your informtion, these are the events that led to this issue.
    I accessed the BIOS settings at startup using the CHANGE PC SETTINGS option in the CHARMS menu in Windows 8 Single Languge 64 bit followed by GENERAL and ADVANCED STARTUP.  Then I chose Restart Now.  Windows restarted to produce the startup screen where I chose Troubleshoot, followed by Advanced Options and UEFI Firmware Settings, followed by Restart.  This took me to the BIOS settings screen. Once there I changed the boot settings in BIOS so that SECURE BOOT was turnned OFF.  It was in ON state prior to that.  I also changed the BOOT MODE to LEGACY ONLY.  I also changed the BOOT ORDER to boot from DVD drive first followed by the Hard Disk and USB Hard Disk.  I saved the changes by pressing F10.
    Now the computer is able to boot from the DVD Drive.  I tested this by inserting a Windows 7 Repair DVD and also a Linux Live DVD.  Mind you, I didn't mke any changes to the Hard Drive.  I'm also able to boot from a USB Hard Disk.  This too was tested by inserting a bootable USB HD that had both Windows 7 and Windows 8 OS installers.  I used only the command prompt feature in the Repair option on the Windows 8 installer to ensure that I could access the partitions on the HD.  I did not in any way install Windows 7 or 8 on the HD.
    If there is no bootable DVD or USB HD inserted, the laptop is involved in a loop that restarts followed by a message that says the following:
    "Intel Undi, PXE-2.1 (build 083)
    Copyright (C) 1997-2000 Intel Corporation
    This product is covered by one or more of the following patents:
    US5, 307, 459,  US5, 434, 872,  US5, 732, 094,  US6, 570, 884,  US6, 115, 776 and US6, 327, 625
    Realtek PCIe GBE Family Controller Series v2.41 (06/08/11)
    PXE-E61: Media test failure, check cable
    PXE-M0F: Exiting PXE ROM."
    I am positive that the current state of the BIOS is such that it does not accept any input keys like F1 and F12 at POST so that the BIOS can only be accessed through Change PC Settings in Windows 8 as I had done prior to the occurence of the issue.  Since I cannot boot up Windows 8 I cannot use this method to access the BIOS.  And since it is not possible at this stage to access the BIOS settings through the F1 key, I believe Lenovo must have surely provided another alternative to enter the BIOS.  Can you kindly tell me what other way is there to do this.  In earlier days, one could reset the BIOS by shorting the BIOS through pins on the motherboard.  Is that possible now?  Or is there some Lenovo BIOS utilily that enables me to change the BIOS setting to boot with Legacy and UEFI?  Or do I have to install Windows 8.1 64 bit in Legacy mode?

    I'll see if another member of the team can jump in here and offer more help...
    What I might imagine is that you can only access BIOS from a cold boot. Windows 8/8.1 have hybrid shutdown and don't completely shut down the machine normally, so even when it powers off, it isn't fully off and the next boot is not really a cold boot.
    Please see this KB.  I realize this assumes you can get into windows.
    As you suggest, it also seems as though you have set legacy vs UEFI and that may be why your drive is not currently booting.   Can you remove the battery on your system?  If not, is there a reset hole on the bottom?  Removing battery and AC and pressing and holding the power button several times, then re-attach AC and Battery and try to restart and press F1 to get into BIOS.  (Not familiar with models that use enter for BIOS).

  • Kernel Panic/Trap error, can't boot up?

    I was installing the 10.6.8 update combo, and it completed and I restarted.  About 10 minutes later, a gray screen came up and a box that said "You need to restart your computer.  Hold down..."  with the four other languages. 
    I tried to restart, but instead of bringing me to the log-in screen, a gray screen came up with the error "panic(cpu 0 caller 0x2abf6a): Kernel trap at 0x0029a4b6, type 14=page fault, registers:"  and then it goes on to list a bunch of things that I'd rather not type, but will if necessary.
    I tried restarting by way of the power button a few times with no luck.  I then tried holding option+command+p+r until I heard the start up chimes three times, but that didn't make it work either.  It did, however, make it so that every attempt at booting was much slower.  It now stays on the gray screen for at least 5 minutes before the little Apple logo appears and it begins to load.  I also held down shift while booting, and put in my osx disk and held down D.  Nothing has brought me to even a different screen.
    What else can I try?  I'm leaving for college in less than two weeks, and it's essential that I get this repaired as fast as possible.
    This is a 13 inch aluminum unibody MacBook running Snow Leopard 10.6.8.  It has 4 gb of RAM and a 500 gb hard drive.  It runs an Intel Core 2 Duo Processor (2 ghz).  And has an NVIDIA GeForce 9400M graphics card.  This is from memory so I'm hoping it's right. 
    Any advice? 

    Hi Frank
    Reset the SMC exactly as described in the article:
    http://support.apple.com/kb/HT1543
    It could be that the cord or surge protector was damaged, try using a different power cord and a different surge protector.

  • Can't boot into Windows 7 after using Boot Camp

    So I installed Windows 7 on a separate 70GB partition using Boot Camp. Everything seems fine, but once installation finished and the computer restarted for the final time, the computer shows the blinking "_" on the black screen and then promptly reboots and this cycle continues without end.

    Sounds stuck at the Windows bootloader. It's not clear why. I would zap PRAM by holding command-option-p-r at the startup chime until you hear a 2nd startup chime. Let it boot back into Mac OS. Insert the Windows 7 install disk and reboot, holding down 'c'.
    Read this, in particular the 3rd option below the screen shot To open the System Recovery Options menu using the Windows 7 installation disc or a USB flash drive, or a system repair disc
