Ubuntu Has Created A Boot Problem
I've been using Ubuntu on my mobile machine for a while, and have been really liking it for "work" stuff, so I decided to bite the bullet and install it on my iMac. Right off the bat, I made a huge mistake. I didn't read the Ubuntu FAQ that explicitly states Ubuntu cannot be installed on an external drive, so I tried to put it on an external 1TB My Book drive that I have plugged in. My second error was forgetting to specify the partition that GRUB was to be installed to. Default option is installing to the internal drive, which is where I have OS X installed.
When I tried to boot, my Mac gave me a white screen and a flashing folder, which I assume meant something along the lines of "no bootloader." I was able to boot from my OS X install CD and copy my entire internal drive to a second external drive that I have, so I wouldn't lose any data. On the ensuing reboot, holding down the Option key seems to allow me to boot from the external drive! This isn't what I was anticipating, so I've been running off the external drive while I look for a solution to repair my internal drive's boot situation.
Do any of you know how to restore Mac OS X's default bootloader from my Snow Leopard CD? I'd also be content with restoring GRUB, even though it would only have one option (boot to OS X).
Thanks for any help you might be able to give.
I attach links to suggestions to repair mbr and remove grub using the fdisk command.I make no comment on how successful they might be.Do at your own risk.

Z68a-G43 (g3) overclocking has failed message/boot problems
Mobo- z68a-G43 (g3)
Cpu- Intel Core i5 2400 3.10ghz
Memory- Kingston 4gb (2 sticks)
VGA- NVIDIA GeForce GTX 460
PSU- Thermaltake TR2 600w
Windows 7 Ultimate 64bit Service Pack 1
I just built this computer two months ago and it was running perfect. Then I started getting a black BIOS screen when ever I turned the computer on. It said "Warning! Previous overclocking has failed. Press F1 to go to set up. F2 to reset settings and continue." This confused me because I have never put it into overclock. Soon after when I tried to turn my computer back on it would not boot. It tries to boot up several times and only the fans spin. The only way to stop it is to turn the power switch on the psu off. After all this occurred my psu would no longer work either. I sent both my mobo and psu in for warranty and just now got the new ones back. I put it all together and it was working perfectly. A few days later the same message came up again "Warning! The previous overclocking has failed. Press F1 to go to set up. F2 to reset settings and continue." I reset it to the defaults and all the BIOS are updated but it has happened again. My computer will no longer start up but my psu is still functioning at least this time. I have reset the CMOS, tried one stick of RAM, took the comp apart made sure everything was firmly in place and put it back together, and tried unplugging everything but the basics but still the same issue fans run and it keeps trying to start up over and over and never boots. I refuse to believe that this mobo is broken because it is brand new. I was wondering if there is some sort of compatibility issue or voltage problem but I can't figure out what to do. Please someone give me some help. It is very much appreciated.Thanks but I finally figured out the problem. The socket is set to 1333MHz and I have my RAM at 1600MHz. I just had to manually clock it higher becasue that is overclocked.

Hello,
Recently, I had a task where I needed to install a custom non-signed driver onto my Windows 8 64-bit setup. As it is known, Windows has driver enforcement policies that, as a security measure, do not allow you to install non-signed drivers.
I did not want to alter my current boot configuration so I decided to create a separate boot entry that would have driver signing policies disabled. For some reason I did not find any good source that would contain a step-by-step instruction on completing
this task, so I decided that I'd better share my experience here.
Lastly, there are multiple ways how you could turn off driver enforcement policies, but I find the way to do this via boot manager.
Here's how you can do that.
1. Press WindowsKey and type 'cmd' (without quotes) to find Command prompt, then click Command prompt icon. If you have User Account Control turned on, hold Ctrl+Shift keys pressed when clicking the icon.
This will force Windows to ask you for elevation of command prompt. Elevation is necessary for editing Boot Configuration Database (BCD), the database used by Windows boot manager to store boot settings.
2. In the User Account Control window click Yes to confirm elevation of command shell.
3. At the command prompt type
bcdedit
to list your BCD entries.
This will give you an output like:

The section that starts with Windows Boot Manager lists current settings for the boot menu. Here you find what boot entry is chosen by default, this is the one what you will boot into if you do not select any boot entry in the
boot menu.
The following record
default {current}
indicates that by default my Windows boots into configuration which I use at the moment (currently booted Windows configuration).
To find out what exactly is current configuration, look into the list of boot entries, records that contain boot loader configuration and are titled as Windows Boot Loader in the bcdedit output.
For example, the entry shown above is one of my boot configurations. This is one of the boot entries listed on the boot manager screen when I start my PC and it looks like:
Windows Boot Loader
identifier {a329b5d0-fb29-11e1-a74d-f2c962d62240}

systemroot \Windows
resumeobject {a329b5cf-fb29-11e1-a74d-f2c962d62240}
nx OptIn
bootmenupolicy Standard
This record has a unique GUID identifier that can be used to reference this boot entry, which is:
identifier {a329b5d0-fb29-11e1-a74d-f2c962d62240}
If we look at the Windows Boot Manager settings, we'll see this entry is the first in order to be displayed in the boot menu on OS start (I marked the unique bits):
displayorder {a329b5d0-fb29-11e1-a74d-f2c962d62240}
{a329b5cc-fb29-11e1-a74d-f2c962d62240}
It references my VHD drive, a virtual hard drive where my Windwos 8 setup is residing:
device vhd=[D:]\win8prowmc01.vhdx
And it also specifies that the boot manager must use UEFI BIOS extension code to access my Windows boot partition:
path \EFI\Microsoft\Boot\bootmgfw.efi
3. Now locate the current boot entry.
Current boot entry contains boot settings used to boot into Windows configuration to which you are currently booted. It is referenced in the list of boot entries as a Windows Boot Loader record that has the {current} keyword inside and may
look like:
Windows Boot Loader
identifier {current}
device vhd=[D:]\win8rtm.vhdx

Because we are more than happy with current configuration and want to base our new boot configuration on these settings, we need to copy this boot entry ({current}) to a new boot entry.
This is done by running the following command:
C:\Windows\system32>bcdedit /copy {current} /d "No Driver Signature Check"
Parameter /d here indicates that the following sequence of characters specifies the display name for the new boot entry that we are creating. The name inside the double quotes will be displayed in the boot menu when you boot your Windows.
In other words, if you know restart your system, you'll see the new No Driver Signature Check in the boot menu.
When copied, the entry is automatically given a new GUID identifier, so upon running the command above, you'll see the following line returned (you'll have an other GUID since these are unique identifiers):
The entry was successfully copied to {a329b5d8-fb29-11e1-a74d-f2c962d62240}.
4. Make sure the entry has been successfully created.
Run the same bcdedit. (You may specify /enum or /v, or both /enum /v parameters at the prompt to get more detail about boot entries, but simple bcdedit is just enough to see the new entry):
C:\Windows\system32>bcdedit

The entry has been created and given a unique a329b5d8-fb29-11e1-a74d-f2c962d62240 ID. It now has exactly same boot settings as the boot entry we used to boot into current configuration of Windows.
5. Modify created No Driver Signature Check entry and specify that Windows must have driver integrity checks disabled when booted using this boot entry.
Any modifications to boot entries are made using /set parameter. To indicate that we modify a specific boot entry, we must specify the GUID for the No Driver Signature Check record, which is:
identifier {a329b5d8-fb29-11e1-a74d-f2c962d62240}
In other words, to edit (add or change) an option for the boot entry, we need to use the following command syntax:
C:\Windows\system32>bcdedit /set GUID <boot_option> [<option_value>]
First, we must specify that we don't want integrity checks be made. This is done by adding the loadoptions option and setting it to DISABLE_INTEGRITY_CHECKS value:
C:\Windows\system32>bcdedit /set {a329b5d8-fb29-11e1-a74d-f2c962d62240} loadopti
ons DISABLE_INTEGRITY_CHECKS
The operation completed successfully.
6. Verify that load option has been added.
Run the bcdedit command:
Windows Boot Loader

7. Add the option that turns on test signing mode and disables checks of driver signature.
Adding the testsigning option and setting it to ON does the trick for us:
C:\Windows\system32>bcdedit /set {a329b5d8-fb29-11e1-a74d-f2c962d62240} TESTSIGNING ON
8. Now we have a boot entry that enables Windows not to do integrity checks and digital signature validation.
We check it by running bcdedit:
Windows Boot Loader
identifier {a329b5d8-fb29-11e1-a74d-f2c962d62240}
device vhd=[D:]\win8rtm.vhdx

nx OptIn

9. Type 'exit' without quotes to exit from command prompt, and restart Windows.
Upon booting you will be present with a new boot option to start Windows in configuration that allows you to install custom non-signed drivers.
Hope this will help anybody to create their own custom boot configurations.

A few days ago I tried to e-mail a friend, when I started A box came up and it required me to add a plugin..Java. I contacted my e-mail courier and microsoft, they told me that is was a plugin from Mozilla Firefox. Since then I must go through Java to send or open an e-mail... this is NOT to my satisfaction, it takes too long for all of this to open and if it is not cleared , I am dropping Mozilla and going elsewhere. Why has this occurred? Is this a result of the last update? If so can I delete the last update and continue on the other version?
== This happened ==
Every time Firefox opened
== last weekSorry, I have no idea what you mean by '''"The Java plugin has created a time unfriendly issue with my e-mail account, I can not open or send any e-mail without using this plugin,"'''.
If you think your problem is caused by the Java plugin, you should visit the Java support forum for assistance.
http://forum.java.sun.com/index.jspa
If you could explain what you mean by '''"time unfriendly''' issue with my e-mail account", maybe we'll be able to help you solve that issue.
It might be helpful for us if we knew exactly which web-mail provider you are using. It seems strange to me that viewing or sending web-mail would actually "need" Java for operation, its more likely that some other item on the web page needs Java to run some advertising or other garbage that isn't a necessary part of the web-mail functionality you want to use. -
Hi, I have an early 2008 Mac Pro which has re-booting problems.
Processor speed is: 2.8
Memory: 2GB 800 MHz DDR2 FB-DIMM
2 x 28GHz Quad Core Intel Xeon
I am running OSX Yosemite Version 10.10
My Mac Pro keeps re-booting. Last year I had to replace my graphics card. My original card was the ATI Radeon HD 2600 XT 255MB, and that is what I have now. At this precise moment my Mac Pro is running perfectly, except that it is slow and the spinning beach-ball keeps appearing. I have managed to do some work with the disk utilities, verifying, cleaning and partitioning. Some errors were found and when it was cleaned this seemed to help my Mac Pro to function properly. Although I am able to use my Mac Pro now, from day to day I still experience re-boot problems. Also quite unexpectedly my mac dictionary has an error, it closed itself down and will not open at all, I had the message to say that a report will be sent to Apple.
I have tried starting my computer with an external hard drive fitted via a USB cable, I use for back-ups. This worked and I was able to wipe my hard drive clear and replace all info from the back up I had done only a few days ago.
This worked for a few days and then the same problem started again.
I am beginning to wonder if I need to buy a new hard drive.
If there is anyone who has some answers to help me solve my problem, I would be most grateful.

Hello al!
I created a website with iWeb but use GoDady for hosting it rather than MobileMe. The images on my Gallery page do not show at all on the external domain but they DO show when seen on MobileMe. Has anyone encountered this problem before? Many thanks!Just create a new page (or use the existing photo page) on your external site and use html to add an iframe sized to the page and link it to the mobilme gallery page. Works for me just fine when showing my gallery from a yahoo site.

I want to reinstall CS4 as it has been doing some strange things regarding printing, etc. However, when I did this before, it created a major problem and I ended up buying a new computer because no one could figure out why it kept hanging up during the installation. Hours on the phone, no results. I'm scared to do it on this computer. Should I try? Not even the Adobe support could get it resolved. I believe it was somehow reading a product number that could not be deleted or something, and nothing worked.
Message was edited by: Doug DougHello, as an addition:
In your case I would download a really new trial version of your program(s) in question and change it/them into a "real" version later, BUT because you said, that you "re-installed" already, so it will become a little bit more complicated. It would be necessary that you have to use "Adobe Creative Suite Cleaner Tool" as Keith wrote.
Here an advice for that (The order varies depending on your individual needs. Please read all my proposals first, so you can better choose the first step:)
1. Maybe you have to activate/deactivate, so please have a look there:
http://helpx.adobe.com/x-productkb/policy-pricing/activation-deactivation-products.html
2. Sometimes, we know in the meantime, the "opm.db file" is the culprit. In this case you should delete it.
3. Be careful with (de)installing aso. by (de)installing by your own resources. As much as I regret it and as strange as it may seem I fear it's a challenge for Adobe's Creative Cloud Cleaner Tool. Sometimes - for whatever reasons - CC doesn't "want" to work. In this case you should CC completely delete and reinstall by help of Adobe Creative Cloud Cleaner Tool. (A try to uninstall by own resources is not enough!)
I quote: Adobe Creative Suite Cleaner Tool helps resolve installation problems for Adobe Creative Cloud and Adobe Creative Suite (CS3-CS6) applications. The tool removes installation records for prerelease installations of Creative Cloud or Creative Suite applications. It does not affect existing installations of previous versions of Creative Cloud or Creative Suite applications.
Please use: http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html and follow the prescribed sequence of operations
4. If necessary and for further questions click through http://helpx.adobe.com/contact.html and if "open" please use the chat, I for may part - as it seems unlike you - had the best experiences. I quote from Adobe's employee Preran: The chat button is activated as soon as there is an agent available to help.

That's nice. Tomorrow you will have 28 days.
What kind of ACC do you have? Nobody that reads posts is omnipotent or has ESP or can read your mind.
Also if you want to converse in English then you need to learn English to the point that you can actually write constructive sentences and paragraphs in English including the proper use of Upper Case, Lower Case and punctuation to some degree.
Otherwise write in your own language on a translator like google translate and paste the translation into your post.
Also you would notice that this forum was supposed to be retired 8/22/2008 if you'd read the stickies in it before posting to it. Which I would suppose is why almost all questions in it go unanswered.

Any Help or Direction would be Greatly Appreciated ,,, Thank You,,, Brian : )
If the memory is low, double click the home button to bring up the multitask bar, tap on one of the apps shown until they start to shake, then hit the little red minus to close them. After all apps are closed that way, press the home button again and see if it works now.
Maybe you'll reset the device as well by pressing the home and sleep button for about 10sec, until the Apple logo comes back again. You will not lose data doing this, but it can clear some glitches as well. -
My MacBook Pro has booting Problems, Light keeps on Blinking. What to do?
My MACBOOK PRO (Early 2011) is having booting problems. It doesnt want to be shut off. If I do shut it off it would take an hour for it to boot. The light keeps on blinking when i push the on button. After a few times of pushing the button and the blinking light the light keeps steady and the MACBOOK PRO seems to be turning on . A Whirring noise/ sound can be heard. I then turn it off and push the ON Button again and the MACBOOK PRO finally boots. The problem repeats again when i turn the unit off.
I already had it checked by APPLE but they said they cannot find anything wrong with it!! Any help will be highly appreciated.Shut the machine down by holding the power button until the computer is off.
Release the power button.
Reset the parameter RAM by powering up the machine then holding the key combination:
<COMMAND> + <OPTION> + p + r until you hear the restart chime three times
Then perform a SMC Reset by following this procedure from Apple:

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.
As Shootist pointed out, the system uses more power.
However, initially it will reindex the hard drive for spotlight, which will slow things down temporarily.
It also must rebuild caches that eventually will speed things up.
If it has completed indexing the hard drive (no dot pulsing in the spyglass), then there might be something wrong.
Start by booting into the Recovery HD (a partition created with Lion that has Disk Utility and reinstallation options) by holding down cmd-r when you restart. You can let go when the gray screen appears.
When it boots, select Disk Utility and Repair the drive.
If that doesn't speed things up, try re-installing the OS from the same Recovery HD. It won't delete any of your files, but it has helped some people whose Macs ran slow after installing Lion.
Also, how much memory do you have? Lion needs RAM so maxing your Mac out might also help. -
hello,
I've an air late 2011. I'm trying to create a bootable SD or USB of a linux distribution without luck, I'm using an EFI ubuntu livecd to do the tests, eventually I found this link
http://studyblast.wordpress.com/2011/08/14/guide-mac-os-x-lion-how-to-boot-a-lin ux-live-system-from-a-usb-drive-how-to-update-any-ocz-ssds-firmware/
tried this procedure on an old white mackbook and worked like a charm but not on my macbook AIR (the boot process stops after few seconds)! At last I decided to give up and bought an external DVD reader, I tried it on my old mackbook and worked as usual (booted all the distributions I had) , tried it on AIR and you know what? DOESN'T WORK.. the boot process starts and then freezes!
I start thinking there's something wrong on my machine, I did a reset of the pram but nothing changed. Can anyone try the link I posted and let me know how the air behaves? I really need to solve this problem
ps please don't tell me to use virtualization
thanksjust to be complete these are the tests I did

Hello everyone!
I've got a PXE boot server running and I can boot my EEE 701 from it without issue, it gets to the installer but then I get asked for the source of the packages. Now, I don't have an Internet connection to the boot server, so that's not an option. I know I can mount something to /src to have the packages show up, but what am I supposed to mount, and where?
Thanks in advance!
P.S: If you're considering "rtfm" or "Google" as a response as some did on the IRC, don't bother wasting your time to type
I mounted a USB stick with all the packages on to /src (I knew that had to be done) but I thought perhaps the installer would have mounted the packages from the tftp server to /src automatically. So now I don't understand the point of the separate installer CD?

Hmm, do you mean the one from here? If so, it says "ftp-installation only", but I maybe should have made that more clear. I planned support for mounting packages from the tftp-server later (you need to set up nfs for that), but never picked it up again.
It is stitched together rather imperfectly, I just made it because there was no other way of getting an install on an old laptop.
I've totally gone around the houses
yeah, you could just have booted from an usb-stick, right?
Actually no! I had problems with that (although I've done it before) I got an error: "Boot device didn't show up after 30 seconds" and the workaround(s) at http://bbs.archlinux.org/viewtopic.php?id=77815 didn't help, so I figured I'd try the PXE boot.
Look, I'll be straight, I use Arch on an old box as a testing / development server for odd jobs. I left Arch as a desktop user a long time ago for Ubuntu where things "just work" - I don't have time to fix things constantly breaking on my main desktop. I thought I'd give Arch another go as a desktop OS on my EEE but I don't have the time (or inclination) to mess around with it anymore.
Ubuntu is installing from a USB stick as we speak.
Don't get me wrong: I LOVE Arch, as a headless, non-important playing around OS, I don't think I'll be using it as a desktop
P.S: Using Ubuntu has NOTHING to do with the skill level of anyone who chooses to use it. I HATE elitism! (rant over!)

I'm trying to create MDT boot images using MDT 2012 U1 on CM 2012 R2 but I keep getting this error message as desribed by this entry on
James Bannan's blog
The suggested fix/workaround is to launch the CM console as administrator. I've tried that with no success and wondered if anyone else has seen this and perhaps knows what the problem is? Any help would be appreciated. Merry Christmas!Thanks, is 2013 required or recommended? The guys running the server re-installed WAIK and the process completed successfully.

Help creating a boot disk for ailing powerbook (and journalist!)
Hello, I'm a journalist with a desperate need to recover my Mac.
My Powerbook G4 (operating 10.4.8 I believe) was working fine until I did the latest suggested Mac software upgrade of Safari. Immediately Safari stopped responding hanging up or quitting. So I tried the next recommended update, thinking perhaps the two went together: Security 2008-009 I believe. It required a restart, which I did. (Note: I didn't do the recommended Java or Quicktime update at the same time because I'm currently working in Sierra Leone with terribly slow internet and figured I'd get to it later).
Now, however, the computer won't boot up. I hear the tone, I get the gray screen with the apple, I get the blue screen, I get the opening OS X screen and the blue progress bar, which then quits early on. Then I get a blue screen of alternating hues, which continues infinitely.
I tried all the Apple and web-suggested fixes. I cannot enter safe mode and can only perform functions with the single user mode. I've tried fsck and it said my HD is fine. The problem, I suspect, would be easy enough to fix if I could just reinstall OS X with my CD. However I am currently 7000 miles from home and CD, and in desperate need of my laptop in order to continue my volunteer work.
I do have access to a friend's MacBook Pro 10.4.9 and the internet. I have downloaded Carbon Copy Cloner... however I don't know which files I need to copy in order to create a boot disk. Nor do I know how to create a boot disk to actually put into my computer. I have also been scared by the CCC literature that says I need to erase the target volume... which in this case is my external hard drive containing all of our video footage from the last 8 months!
I use my computer every day, however I am a newbie at using things like Terminal and higher order functions that these occasions seem to require. CCC's Help manual, for me, might as well have been written in hieroglyphs (which, come to think of it, would have been easier as I seem to understand pictures well enough).
I would be eternally grateful for any simple or step-by-step advice which might help me get back to work. I'm training African journalists, and without my computer to edit, we cannot do a thing!
Thanks,
KimHere's some trouble shooting methods that I've copied from Apple KB articles:
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time. Release the keys.
If zapping the PRAM doesn't work, try resetting the PMU.
Warning: Resetting the power manager also resets date and time settings. Performing a PMU reset returns the iBook and PowerBook hardware, including NVRAM, to default settings and forces the computer to shut down.
PowerBook G4 (DVI) and PowerBook G4 (1 GHz/867 MHz)
If the computer is on, turn it off.
Disengage the two keyboard latches located between the Esc and F1 keys, and the F11 and
F12 keys. (You may also need to disengage the keyboard locking screw located between the
F5 and F6 keys.)
Lift the keyboard. To ensure no harmful static electricity is transferred to the computer,
properly ground yourself before performing this procedure.
Press and release the reset button located on the upper right side of the logic board near the power button, shown here. Wait 5 seconds.
Press the power button to restart the computer.
PowerBook G4 and PowerBook G4 (Gigabit Ethernet)
If the computer is on, turn it off.
Press and release the reset button located on the rear panel of the computer between the
external video and modem ports. Wait 5 seconds.
Press the Power button to restart the computer.
HTH!
