Alt boot up is gone. MacPro 2012
Hi !
I´m on a Mac Pro with 2 harddrives (each 1TB) and one PCIe SSD 240GB. I was running Snow Leopard on HD in rack 1 and had Boot Camp on the HD in rack 2 (Win7). I made a clean install of Mavericks on the PCIe drive.
Everything was going great untill I was trying to boot with "alt key" down. Then came the "white screen of death". Nothing happens. No pictures of bootable disks.
I can change the boot disk and go to Windows via diskutility. I can re-boot back to Snow Leopard from Win 7 (not Mavericks). And then I can change the boot disk once more and be back in Mavericks.
Why? What happened with the Alt-key boot up screen? Is this due to the fact that Apple does not support PCIe disks? Should I reinstall the drive in rack3? Or is there an incompatibility here?
Anyone?

Hello Ice44,
I would be concerned too if I was unable to access the Startup Manager anymore. I recommend resetting PRAM for the issue you described:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys 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.
You can find the full article here:

Dear Sir or Madam,
I have been experimenting with the evaluation version of WS2012e trying to get the installation and subsequent build into an optimal set up, and once I have everything I want it to do mapped out, I'll set it up with the full version with using the key that
I bought.
However, I've noticed that the server seems to experience a delay during cold boot - it sits with a Please Wait screen for about 60-90 seconds before it presents the screen with an option to Log on. I have also discovered from running Health
Report, that there are some entries in the event logs which appear to coincide with start up times, and which seem to be interconnected to each other in the issues they are describing, and I have copied an example of one of those health reports below.
I assume that everything sorts itself out in due course, because the events say the process will be re-attempted and these errors don't repeat again after the system has booted up. I also have the server set to suspend when not in use with the Lights
Out add in, so it shouldn't need to cold boot often - but I wondered if there's a way to correct these errors so that they don't hold up the boot up process? I'm also concerned that these errors will cause me later problems with storage pools and
the like at a later date - the disk replication one seems particularly worrying. Alternatively, are these errors just a normal part of the start up process - the timing of when different processes start relative to each other - and can be safely ignored?
In trying to understand what the events describe, I thought that WE2012e acted as its own Domain Controller, and yet it seems from the event log entries that it is waiting for another server to respond to AD / DC requests (but there isn't another server
on my home network). The other thing I remember from when I first tried out WS2012e, is that it took control of DHCP or DNS from the router, and I found that frustrating when waking up my laptop and it wouldn't connect to the internet until the server
had fully booted up and re-asserted its network settings. Is this another symptom of the same problem? I remember seeing a posting at the SBS Diva's site about how to update the server so that it gave connected PCs a backup option for connecting
to the internet when the server wasn't available, and was going to try to find that again to see if that helped.
By way of background - there isn't another server in my home network. This is an attempt to do a clean install onto the same hardware that I ran the initial trial of WS2012e, now that the trial has expired, so I'm not trying to migrate from an existing
server. I moved all the data on the trial server off onto an external disk, with the intention of importing it back once I had the Storage Pools set up the way I wanted on the new build, and since I didn't want to keep anything else about the server
trial. Am I correct in thinking that I don't need to go down the Migration route during installation, and can go through a Clean install in this circumstance?
I'm running on an Asus P8-H77-i motherboard, with an i5-3470s CPU and 16MB RAM, and I have WS2012e installed on 256Mb SSD formatted under GPT with uEFI boot - the latter being the main reason for the reinstall, instead of just giving the Evaluation
version the new key on the original MBR set up. I've also enabled Intel Rapid Storage and Rapid Start - and successfully set aside the hibernate partition on the SSD - but discovered that this is about forcing a hibernate after suspend, allowing
the system to power down until its needed again, and then resuming from hibernate on the SSD rather than cold boot each time. That seems to work, but doesn't improve the cold boot times at all, which was what I was hoping for - ideally the way my
laptop will boot from cold in a few seconds into Windows 8.
Yours faithfully,
Avon

The security of this directory server can be significantly enhanced by configuring the server to reject SASL (Negotiate,
Kerberos, NTLM, or Digest) LDAP binds that do not request signing (integrity verification) and LDAP simple binds that
are performed on a cleartext (non-SSL/TLS-encrypted) connection. Even if no clients are using such binds,
configuring the server to reject them will improve the security of this server.
Some clients may currently be relying on unsigned SASL binds or LDAP simple binds over a non-SSL/TLS connection,
and will stop working if this configuration change is made. To assist in identifying these clients, if such binds occur this
directory server will log a summary event once every 24 hours indicating how many such binds
occurred. You are encouraged to configure those clients to not use such binds. Once no such events are observed
for an extended period, it is recommended that you configure the server to reject such binds.
For more details and information on how to make this configuration change to the server, please see http://go.microsoft.com/fwlink/?LinkID=87923.
You can enable additional logging to log an event each time a client makes such a bind, including

Hi Justin,
I'm reading through the links you referred me to but it's taking a while. In the meantime I tried running BPA as you suggested. I'm sure when I ran it before, it didn't say much beyond 81 checks completed, and I couldn't find a way to get any
more detail.
Now it says
Problem:
The DNS client is not configured to point only to the internal IP address of the server.
Impact:
If the DNS client is not configured to point only to the internal IP address of the server, DNS name resolution can fail.
Resolution:
To resolve this problem:
1. From the client computer, open the Properties page for the network connection.

I am new to Gen2 Hyper-V and so far I simply can't use it, because I am unable to install any (supported) guest OS from an ISO ...
So far I tried that on:
1. my HP Z230/i4770 workstation (Secure Boot disabled) host running Windows 8.1 Pro x64 (with Hyper-V feature enabled), can't boot any VM with supported OS ISO.
2. my home desktop/i3770K (secure Boot enabled) host running Windows 8.1 Pro x64, same result, error during VM boot from ISO, quoted below.
Synthetic SCSI controller (instance blah blah) Failed to Power on with Error 'The version does not support this version of file format'
Gen1 guests of course work perfectly fine with those ISOs, because emulated DVD IDE picks up the official Enterprise Evaluation ISO of either Windows Server 2012 R2 or Windows 8.1 x64 Enterprise, perfectly fine and all works OK in Legacy boot mode.
When I create a new guest and select Gen2, then no matter if I check or uncheck the Secure Boot in virtual Boot Order options for the guest (while setting the SCSI DVD at top of course), it simply doesn't work, always same error. I tried first connecting
to VM to see if it prompts for key press, but it doesn't, the error is instant on Power on when (supported) ISO image is selected to be booted.
I verified that both of official Enterprise Evaluation ISO's of either WS2012r2 and W8.1x64 are bootable in both the UEFI mode (Secure Boot enabled) and Legacy BIOS mode using a physical computer.
What am I missing here???FYI, above is wrong! it's not about linking ISO to virtual DVD or selecting "Install OS later", it's all about the location of the ISO file and share permissions on parent folder!
I was actually suspecting several issues, but haven't had time to test it, was thinking about issues like assigning (or not) some of initial settings during Gen2 VM creation, e.g.:
-Network connection through virtual switch or Not Connected (make no different if assigned or not)
-Memory above 4096MB (makes no difference if < or > 4096MB)
-ISO file location (makes huge difference!)
The ISO file CANNOT be placed on network share OR in shared folder on same local drive as the VHDX file (works fine if parent folder is not shared).
I can now replicate the issue easily every time and it always fails with file format unsupported message whenever I have the ISO file located either on remote network share, or (fails the same way too) when I have the ISO file placed locally (on host drive)
when simply a parent folder is shared... must be some permissions issue... and a pretty dumb one considering that in production environments nearly everything is placed on remote file servers ...
... so the moral of the story is, if you want to install Gen2 VM in win8/2012 hyper-V then you must copy the ISO file to Hyper-V host drive AND make sure the parent folder is not shared. works every time now! :) -
Samsung SSD 840EVO not booting from macbook pro mid 2012 after cloning
Hello there,
I guess i'm so stuck with the SSD that i have purchased.
Here is the details:
SSD - Samsung SSD 840 Evo 250GB
MacBook Pro - 13-inch, Mid 2012
Model Identifier: MacBookPro9,2
Processor 2.5 GHz Intel Core i5
Memory 16 GB 1600 MHz DDR3
Graphics Intel HD Graphics 4000 1024 MB
Software OS X 10.9.1 (13B42)
Boot ROM Version: MBP91.00D3.B08
SMC Version (system): 2.2f44
I was running with the factory HDD (toshiba 500gb) and thought of replacing it with an SSD . Tried a clean installation of mavericks at first using Bootable USB drive having mavericks. So i went on and installed the ssd replacing the HDD i had and went on to boot up from the USB, prior the installtion i tired to partition it first with single partition MAC os extended journaled with GUID table. But then it did partition but after that it says trying to reinitialize the drive and it never came back although i tried more than five times. So then i went back to my HDD and tired cloning it to SSD using Carbon Copy Cloner, but even for that i had to do the partitioning which failed. Finally i had to go and return back that peice and they gave me another one convincing me that it might a defective peice.
Now, with the second one, at first i booted up my HDD normally and connected the new SSD the USB/sata converter and i successfully partitioned and using carbon copy cloner, i have cloned as well. Now to make sure if its all ok, before replacing the HDD in the main compartment, i just selected the startup disk as the new SSD and restarted the system... it booted up fine like a cheetah... was all gud... i thought everything is pretty fine. Then ofcourse i went ahead and replaced the HDD and powered up the system again, but then it's not booting up... it gives you that folder with ? mark and that's all...
And then i tried some other ways too... i even checked the firmware versions and i guess they are upto date as well. I just dont get the reason why it's not working.
Please help me.
Anjillanyea... i have tried all those...
can you confirm if this is ok to buy:

Can't Dual Boot 8.1 and Server 2012
Hello folks; I hope someone has a solution to this issue. Right now, I'm stumped; and, I can't seem to find an answer on the net.
I have a crash-and-burn system, an HP Envy 700-400z, with an 256m SSD that came partitioned into Windows & Recovery at the factory; and, a 1T HDD drive. I want to load this machine with a couple of OSs; but I can't.
My first try was with Win2012; and, one of two things happens. If I try to install Win2012 to the HDD, the installation hangs; and, I have to back out the installation.
I then shrunk the partition on which Windows 8.1 sits; and created another partition for Win2012 to see what would happen. I mounted the new partition from an Empty folder in the now shrunk partition. I did get a message when I installed 2012
that the partitions are not in the correct order; but, I went ahead anyway with the installation just to see what would happen. This seems to work for awhile; and I can boot to either 8.1 or 2012; but at some point, I lose network access. I get
a message that the controller has an invalid IP configuration; and, nothing works but restoring the disk image to factory setting.
If it did work, it, obviously, won't work long term; because, I can't keep shrinking the one partition on the SSD to load SUSE Linux and other OSs that I want to use for my studies. I know I can use Hyper-V as a resolution for multiple OSs; but at
the moment, I want to understand what the deal is with GPT and the installation problems I'm having.
I suspected GPT has something to do with my problem; but am not sure. I read up on UEFI; but, both the SSD and the HDD are GPT drives. I've looked elsewhere on-line; but I come up with nothing that addresses the issue except for general discussions
on GPT. Ideally; I'd like to restore the original boot partition on the SSD to its factory setting, and carve up the 1T HDD for all the other OSs before I tackle doing the same thing with Hyper-V.
At this point, there's nothing on the machine but two OSs and SQL Server 2012; and I have the recovery disks if I happen to shoot myself in the foot; so, it doesn't matter what I do to the disk configuration. GPT is new territory for me; so, any help
with this problem is greatly appreciated.Hi,
According to your description, my understanding is that you want to deploy dual Boot Windows 8.1 and Windows Server 2012 on VHD.
I recommend you to confirm that if your device meets the requirement:

Selecting a boot drive for Hyper-V 2012 server - is a boot drive performance important?
I'm setting up a new Hyper-V 2012 server dedicated to virtualization and I'm trying to determine the best choice for the boot drive.
I have 2x250gb SSD drives i'm considering for storage pools for VM's
I have an old 80GB SATA drive
I'm wondering how important the primary boot drive is in a Win 2012 Hyper-V setup. I can partition one of the SSD's to provide a boot partition, or I can just dedicate the 80GB SATA.
What do you think would be a better choice?
Edit: A more precise question, why not partition the SSD for boot? Is there any benefit for separating the disks for boot vs just the partition?
Thanks,
DecoHello,
I hope you are having a great day!
What resources are available to you? If you have hardware RAID, it would be best to configure the SSD drives for RAID 1 (mirrored) and run everything from that. This will provide you fault tolerance in the case of a drive failure.
If hardware RAID is not available to you, then definitely use the 80GB SATA drive as the OS Boot Drive, without a hardware RAID for the OS disks you will have a single point of failure no matter what disks you use. Yes with SATA drive the system will boot
up slower :-( , but that is about the only negative.
This will also enable you to leave the SSD's as RAW un-formatted disks which can then be configured in a Storage Pool with mirroring if you wish and then have the VHD's reside there.
Absolutely, dedicate the SSD's for the placement of the Virtual Machines Config and Vhd/Vhdx Files.
For absolute best performance results use VHDX Fixed disks for maximum performance.
Dynamically expanding VHDX will have a minor almost unnoticeable performance hit (depending on the purpose of the VM) and help ensure that the amount of hard disk space the VHDX file is occupying is kept to a minimum. An example of degradation in performance
would become noticeable if for instance, the VM is being used as a file repository and users are constantly uploading files.
The bottom line is, if you don't have hardware RAID for the OS you always have a single point of failure, so hope for the best and keep great backups. -
Ubuntu CD showing up as Windows in alt boot screen
Hi everyone,
The problem began when I tried installing Windows 8 Release Preview using bootcamp assistant on my 2012 MacBook Pro 13. First, bootcamp assistant couldn't create a bootable USB stick; I tried it numerous times and it kept giving me the same error (something like 'the windows installation fle could not be copied'). After a couple of hours and three different USB sticks, I burned the ISO file onto a DVD. With this DVD inserted, I used bootcamp assistant again, only this time I didn't check the first option that creates a bootable USB stick. I assumed bootcamp will create a partition and install windows from the DVD. The partition was created and bootcamp assistant rebooted the computer, presumably to install Windows 8 from the DVD (i'm assuming everything was fine till then because I didn't get any kind of error message). But instead of starting the installation, the screen turned black, and a white cursor began to blink incessantly. Worried about terminating the process I let this go on for hours. Finally, losing patience I shut down the computer by holding down the power key. I turned it on later and after this happened a couple of time (the DVD was still inside) I held down option key while booting and booted into macintosh HD. There was no problem after that.
I now want to install Ubuntu. But strangely, if I boot from the Ubuntu CD, the same ominous black-with-white-cursor screen is showing up, and if I hold option to show booting options the Ubuntu CD is showing up as Windows! (on the desktop it shows as Ubuntu).
I have no idea what's going on! Help.I believe I've made my intentions quite clear. Let me repeat: I want to install Ubuntu on my mac as an alternate operating system. But I am unable to do so because everytime I insert the bootable Ubuntu CD, and try booting from it, the Ubuntu CD shows up in the boot menu as Windows. When I select it the same blank screen appears that appeared while I was trying to install Windows. Why is the system reading the Ubuntu disk as a Windows disk and how do I repair this?
And I really don't know what you mean when you say:
First, bootcamp assistant couldn't create a bootable USB stick
Windows will only install on an Internal drive, I believe this is a Windows limitation.
The whole point of bootcamp assistant is, apart from making a partition, to help you create a bootable USB stick and then install it from there. -

Crippled from loss of displays upon restarting from alt boot drive
HI,
I Selected for restart an alt internal drive startup disk (previously tested and confirmed working) that I had cloned for a backup.
upon restarting my dual displays do not respond at all under any circumstances so I find myself crippled. They don't even flash anything. Same if I try just running one display.
I've tried every startup key command in the book including holding option, shift, C with snow leopard DVD inserted, and still nothing. I reset PRAM and my startup sound is now louder so I know that worked, also at one point I ejected a. DVD with command E, so it seems it's booting, but where did the graphics card/displays go, and how to get them back?
2008 Mac Pro, OS 10.9.2.
thanksUpdate from jeebs 2:
Next morning I try just plain old booting again for the heck of it, and it......worked...(?!). HAPPY.
It went ahead and booted from the original drive I had been using before the crisis (YAY), and now I'm very hesitant to try booting again from the backup (which is sporting an OS version I was considering reverting back to), although that backup drive has mounted and is looking fine...... -
Can't boot Win 7 on my 2012 iMac anymore
Hi all,
I needed windows recently so installed it. The installation was from a windows 7 dvd i always used, and it went fine. But when it came to setting up the windows to run for the first time after the installation, the computer just rebooted. And when i tried to boot into windows it just shows the black screen with blinking dash and nothing else happens.
Something is changed and I don't know what. Maybe just the updated Mac OS X Yosemite? But i tried Mavericks also and snow leopard... I also tried to do bootcamp install and directly booting from the cd... It always installs fine but when it comes to starting it up, windows just stays on black screen. Also tried to instal windows 8. Same thing, installs fine and then when it needs to run - nothing.
What's the reason for this?This is very confusing 2012 iMacs are

Trouble Booting from External Drives - MBA 2012
Hello,
I have a brand new 13" MBA which I'm working on building an image to use for deployment using Carbon Copy Cloner 3.4.5. For whatever reason, I can't boot the new 2012 MBA from an external LaCie FW800 or Thunderbolt 1TB Little Big Disk that is running either 10.7.2 or 10.7.4. As soon as I select the drive to boot from when holding the Options key or from selecting the partition from Startup Disk in System Preferences, I get the do not enter icon(circle with the diagonal slash). I tried both plugged in through a Cinema Display and plugging the Thunderbolt drive directly to the laptop. I confirmed both LaCie drives boot properly on an iMac and the last gen MBP/MBA.
Laptop Specs:
13"
1.8GHz Dual-core i5
8GB
128 SSD
10.7.4
Curious if anyone has run into any problems booting from external drives on the new 2012 MBA.
Thanks,
PaoloPlease be sure you have prepped these external drives correctly:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

My suggestion for cloning is to use Disk Utility. This will also automatically clone the Recovery HD, as well:
Clone Lion using Restore Option of Disk Utility
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Select Disk Utility from the main menu then press the Continue button.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive. -
I have an IMac which won't boot up and when I tried the restore function the Hard Drive next to the Main Hard Drive says it is "locked" when I tried to use it to restore my system. I have Mountain Lion which was working fine until recently. Now I can sit LITERALLY for an hour waiting for the gear to stop spinning but not results for loading the program. HELP!!!
As of 10.8.4, the volume must be unlocked first.
Here’s how the unlock procedure works for Disk Utility:
Boot your Mac and hold down ⌘-R (Command –R) to boot from the Recovery HD partition.
Open Disk Utility.
Select your locked hard drive.
Under the File menu, select Unlock “Drive Name”
When prompted for a password, enter the password of the authorized account on the drive.
Once you unlock the disk, hold down the Option key on your keyboard and click on the File menu.
Under the File menu, select Turn Off Encryption… with the Option key held down, it is no longer grayed-out.
When prompted for a password, enter the password of the authorized account on the drive.
Disk Utility should display a progress window labeled Starting conversion to JHFS+
Your drive should now be unlocked. -
Partition is there, but Windows boot option is gone?
Hey folks, I'm having a small issue with bootcamp.
Not too long ago did I have Windows running just fine on my Mac; everything was up to date, I managed to install 7 and upgrade to 8.1 just fine. Everything was good until one evening I open my Mac up, there is a command line that states "no bootable device." I don't believe I had installed Yosemite because last time I shut the Mac it was in Windows. I found a thread from another user here, and followed LonerT's suggestions and managed to get Windows back as a boot option, but the command line still pops up with "non-system disk."
The bootcamp partition is still on my HD with everything installed, so if there's some way I could get this back to how it was without having to go through the hassle of erasing the partition and starting anew I would be greatly appreciative.
Thanks!Whoa, LonerT!?

I thought the corestorage command was a bit odd so I looked around the web to find out what it means. It doesn't sound promising.
As for you question on "what modifications were made to get [the drive] bootable again:"
I followed these instructions you gave in that thread listed above...
Here is an example.

Saying the Windows is bootable may be a bit subjective; the option appeared after this example you gave, but it won't boot into Windows. -
IMac won't boot, startup disk gone?
Hello, my name is Jesse. English isn't my main language so I'm sorry for grammar mistakes!
I didn't use my iMac much last week. A few days ago I checked my email or something and left it on for about 30 minutes.
When I tried to start up the computer in the evening it went to a grey screen and there were 4 option I could do:
- use a backup
- reinstall mac os x lion
- use safari for help
- something else I forgot
Every time I try to boot the computer it goes to this window so I cant use the computer anymore.
I think the StartUp Disk is broken.
I am pretty sure I didn't do anything bad with the computer to cause this.
Maybe because of the high temperatures lately it broke??
There are files for work etc on the computer that I NEED. So I don't want to reinstall the computer and lose all the files.
My questions are:
- What might of caused this?
- Do I lose all the files on my iMac?
- Can this be fixed easily or is it very expensive?
I tried starting up holding Shift/Option key but both times I ended up at the grey screen with the 4 options.....
Thank you so much if you can help me!
- Jesse.Have you tried booting into Recovery Mode (see OS X: About OS X Recovery - Support - Apple) ?
What version of the OS did the system have on it when you bought it?
As for what caused this, there are a lot of things that can cause a disk drive to fail, age, temperature, shock can all make a disk fail. How old is the iMac?
Maybe you are looking for
