Prohibitory Sign After Login - Deleted Ubuntu Partitions

I booted into recovery to delete my Ubuntu partitions. After doing that I restarted then went back to go login to OS X but when I login to my account it shows the prohibitory sign and the loading symbol. I tried booting back into recovery to repair the disk, but it wouldn't let me mount the drive to do anything. I never touched my Mac OS X partition so my files should all be there. I booted into Ubuntu through a USB to see if I could repair the disk but it says it's "unknown" and it's not showing it as the primary anymore. Also when I deleted the Ubuntu partitions, "Recovery HD" was made. How can I get back into Mac OS X?

My guess is that you somehow managed to hose the GPT partition scheme info on the drive. Someone else may have a better suggestion but I think you should be able to use Internet Recovery (if you have a broadband Internet connection) to reformat the drive & then reinstall OS X to recover from this. Of course, reformatting the drive will erase everything on it, so I hope you have good backups!
Thanks for the suggestion! I created a new partition with the unallocated space, then installed OS X on it then used disk recovery programs to see if I could recover anything and I couldn't. So now I'm at : How do I repartition my new main volume?

Prohibitory sign after update 10.9.4 from 10.8.5

First I would like to say thank you ahead of time for taking the time out of your day to read this and try to help me.
I really appreciate it.
I have 2012 13" MacBook Pro Intel i5 2.5 4GB 1TB
Was running 10.8.5 flawlessly. I thought update to Mavericks because the update notification was annoying me.
Update completed successfully. Upon reboot i get the Apple logo then few seconds later the Prohibitory sign.
I tried booting to the recovery HD and doing a repair on the Macintosh HD with no avail.This is what it says.
The Macintosh HD is grey and when I click on Verify Disk this is what it says...
Verifing volume "Macintosh HD"
Checking file system
Invalid content in Journal
Checking Journaled HFS Plus volume
Invalid B-tree node size
The volume could not be verified completely
Error: This disk needs to be repaired. Click Repair Disk.
I click repair disk then i get this:

Error:Disk Utility can't repair this disk...disk, and restore your backed-up files.
I also tried to reinstall the OS but the Macintosh HD does not come up when I need to choose the HD to install on. Only the recovery partition comes up.
I tried to pull out the drive and plug it into another mac and recover the data but the drive doesn't mount. I also tried doing to disk utility on that computer and I get the same message as above.
I just want to access the data, and I will do a fresh install.
Any ideas?
All help is appreciated.
Thanks

Let me add that Mac A is the machine I am physically logged in on, and I did the check sshing from B to A in a Remote Desktop session, so the situation is not entirely symmetrical.

Prohibitory sign after repairing privileges from CD

Snow leopard was working. I installed the upgrade on an imac 20 inches.
I started from the CD to verify disk and repair privileges.
When I repaired privileges, one file was bad, i think something related to "core"
I restarted and.... have a prohibitory sign! Imposible to enter the system.
I succeed in entering again my system reinstalling the upgrade of snow leopard
How could it be? What's wrong with my system? Do I have to format the disk and reinstall everything from zero? I'm scared this problm could happen again...

You removed everything from your hardware profile sig that, erroneous I'm sure, said you had a G5, which can't run 10.6.
from the CD to verify disk and repair privileges.
The SL DVD 'ought' to be okay to REPAIR the hard drive, and repair permissions (though ideal is to repair from a 2nd hard drive, such as the one you made with CCC).
Leopard definitely saw changes and doing any type of repair work should be done from the SAME OS version as you are running and not from older versions such as on DVD.
The article on kernel panics recommends some steps, such as clearing NVRAM for when you get a prohibitory sign. And to look at and disconnect everything possible as well - USB and FW devices/cables have been known to cause panics.
Why not repair permissions while booted? won't Disk Utility run, even in SAFE MODE when booted from your clean fresh install? though really shouldn't need to.
As for power failure, I would never run a computer without a UPS (uninterruptable power supply) ....

Mavericks won't install after accidentally deleting recovery partition on 10.6.8

I have been searching for hours for a solution and found none.
Essentially, I was running 10.8 on my MBA which originally came with 10.6. Wishing to perform a clean install of Mavericks, I accidentally deleted the recovery partition. Installing Mavericks would then always crash midway; so eventually I reinstalled my original OS from the bootable disc from apple. Then I figure I had to create a bootable disc for Mavericks, which I did, and the result is the same, the installation crashes midway.
Any other way I could install 10.9?
Thanks

Mavericks creates a recovery partition while installing.
So, no previous recovery partition needed.
But playing whith partitions could be a mess.
Try a clean reinstall.

Cannot resize "Macintosh HD" after deleting second partition: OS 10.9.4

I have partitioned my Macbook Pro in order to see if I could install Snow Leopard on one of the partitions, the main HD running Mavericks.
Sadly, my late 2013 Mackbook Pro is not compatible with Snow Leopard (or at least I was unable to determine how to prepare the partition in order that the snow leopard install disc would run successfully). At any rate, after this failed experiment, I deleted the partition I created for snow lion using disc utilities. The problem I am having now is that I am unable to resize the single "partition" to the full size of the drive. I read this thread, Unable to delete second partition, and it suggests booting the mac in recovery mode in order to restore to a backed up version of the HD, however this is suggested as a work around for not being able to delete a partition, which is not my case. Again, my problem is simply that once I have deleted the second partition, I am unable to have the single partition assume the full space of the drive. Any suggestions short of a complete re-install?

Here's the disc utilities snapshot after I deleted the partition that took up the space in the lower part of the quadrant. I'd like the MacIntosh HD to subsume the space leftover by the deleted partition.

Can't boot anything after deleting C partition in order to install Windows 8.1

I have a ASUS X55VD notebook, wich had a Windows 7 64-bit (and a dual booted Ubuntu, but with Windows bootloader). Yesterday I tried to install a Windows 8.1, so I inserted a disc and restarted.
The window to manually select the partition, on wich it will be installed, came up so I formated C partition where Windows 7 was installed. It did not allow me to install to that partition because, a new format (GPT) had to be used. So i chose to delete the
partition. Deleting was quite long, after wich the computer restated, and after that it only showed black screen.
The Windows DVD is still spinning, but nothing shows. Can't acces the BIOS (none of the keys work).
Tried:
- Hardware reset (battery out>hold power button fro 10-20 sec>put battery inside>start) - No change
- Put a Live Linux DVD to boot from it - No change
- Put a hirens boot cd - No change
- USB boot - No change
- Connect a external keyboard and tried accessing BIOS - Nothing happened
I would suffice with just gettng some of my data from him, and sending him to repair Can't tinker with harware, or it will void my varrancy
Please help. The problem is really urgent.

Hi,
It seems a hardware issue, you can first try to reset the CMOS - remove the cell battery from the motherboard for at least half hour, re-insert it, boot up. The BIOS settings should be reset to defaults. But for better solution, I
suggest you contact the manufacture.

My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
Unable to bootstrap transaction group 2517: inconsistent crosscheck
No valid commit checkpoint found
The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
Problems were encountered during repair of the partition map
Error: Storage system verify or repair failed.
(the same with 2518, 2519 and 2520 transaction group)
I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

Can't boot from Ubuntu partition after upgrading to Yosemite

When i go to Disk Utility the Ubuntu partition appears as it always have, i had installed since Mavericks refind to boot from any partition. Now refind doesn't work and the alt/option key doesn't work either. Does anyone know a way to fix this?

A extensive report already written is in the Ubuntu stacks as
Dual boot Linux and Yosemite
Basically you need to follow http://www.rodsbooks.com/refind/yosemite.html
wherein it explains that Yosemite is using a new LVM bootup from within the Recovery Partitions 10.10.
This messes up REFIT/REFIND tools which have previously installed Partition 1.S
See my current Table below , wherein << are my comments
Current GPT partition table:
#      Start LBA      End LBA Type
1             40       409639 EFI System (FAT)    << old preferred site for REFIT/REFIND tools
2         409640    154061023 Mac OS X HFS+ << main Mac partition
3      154061024    155330559 Mac OS X Boot << Recovery 10.10 , installed by Yosemite update, used to start MAC boot. BUT is not shown by Disk Utility, to prevent its naive deletion which would kill the MAC boot.
4      155330560    156598271 Mac OS X HFS+ << old Recovery 10.9, simply retained
5      157869786    228772129 Unknown << My Ubuntu partition
6      228772130    236765969 Linux Swap << which was shortened by 200 MB to make room for 7)
7      236765970    236974814 Mac OS X HFS+ << installation site of REFIND. Though 4) could have been used, there is a possibility that Apple might have future plans for this small 4) partition.
With 7) created (see detail below), my REFIND install command under MAC, within Downloads/refind-bin-0.8.3/ was:
sudo ./install.sh --alldrivers --ownhfs /dev/disk0s7
There was still required the edit if refind.conf.sample specified in Yosemite.html, which I named refind.conf.edit1
This was copied with:
sudo cp refind.conf.edit1 /Volumes/macefi/System/Library/CoreServices/refind.conf
macefi is my name for the MAC /dev/disk0s7 mount point, equivalent to /dev/sda7 under Linux
CAREFULLY do read Yosemite.html, as the instructions here are too terse by themselves!!!!
There are 2 routes to boot Ubuntu, and then creat 7) with GPARTED
a) If you can access the GRUB shell under an old REFIT/REFIND installation, partitions will be shown by:
grub> ls
Presence of a Linux file system can be confirmed by a command like:
grub> ls (hd0,gpt5)/
Output of
grub > ls (hd0,gpt5)/boot/grub/
should include a grub.cfg file. Then you can boot as usual with
grub > configfile (hd0,gpt5)/boot/grub/grub.cfg
After boot up, start GPARTED
b) Alternatively boot with the Ubuntu install disk, and choose the Demo option
Open a text console, and get admin proviledge with:
$ sudo su
# gparted
Using GPARTED, unmount if necessary any terminal SWAP partition, such as my 6) above
Then shrink the SWAP partition end by a trivial 200 MB,
Create a HFS+ partition in like my 7) for a coming REFIND installation
Note, that a file /etc/fstab contains a SWAP partition specification, which should be edited for automated SWAP start.
# sudo blkid /dev/sda7
will report the SWAP space specs LONG uuid code. This can be copied into memory by dragging the mouse over the uuid
Then SHIFT-CONTROL-C will copy it into memory.   Start an edit with:
$ sudo nano /etc/fstab
delete the old swap uuid, and paste in the replacement with
SHIFT-CONTROl-V
and swap should mount upon reboot, or with:
$ sudo swapon -a
Check with:
$ free
which should report none-zero swap space.

Disk utility does not allow to restore Macintosh HD after I deleted a small size (1GB) partition

Hi, when I tried to create a new 1GB partition (on my Mac mini 2011, using Mac OS X 10.7.3) and then to delete it I could not restore (increase) Macintosh HD size using Disk utility (diskutil list shows the same value for Macitosh HD (498,17GB) partition before and after I deleted a new created 1GB partition).
Please help, how I can restore the original size of Macintosh HD when Disk utility does not allow to restore Macintosh HD after I deleted a small size (1GB) partition?
Thank you.

The bottom right corner dragging does not help in my case, because it shows that Macintosh HD partition size is maximal, but its real size did not change after I removed 1GB partition.
Maybe any other idea can help me, for example some built-in tool like diskutil which allows to view and manage unused partitions in terminal?
Thank you.

Slow reboot after deleting bootcamp partition

Hello,
I was just told by a tech store that my bootcamp partition was slowing down my computer incredibly. I no longer need this partition so I went into Disk Utility, clicked the partition, and deleted it. I also had my RAM updated from 4GB to 8GB. I have an Early 2011 Macbook Pro, operating on Yosemite.
The only question I have is, when I rebooted my computer for the first time after deleting the partition, the restarting process took much longer than normal. Without the bootcamp startup, I figured the startup time would be less, when in reality, it was longer. Is there something I missed while deleting my partition, and is there a way to fix this and speed up the reboot time? If not, will this slow reboot be a one time issue?
Any comments would be appreciated!
Thanks,
Rachel

There is a hidden Recovery HD between the OS X and the deleted BC partition, which you can verify using
sudo gpt -vv -r show /dev/disk0
in OSX Terminal.
BCA does a better job by also relocating the Recovery HD appropriately and giving you a contiguous partition.
The only other method is to subsume Recovery HD in OS X partition and then re-install OS X which will rebuild Recovery HD. This does not modify any of you files, but just the OS.
You will also need to clean the Hybrid MBR which is now dangling and inappropriate for your case.

Error 0x80070057 After Deleting Bitlocker Partitions

I'm in the process of configuring OSD through SCCM 2012 R2 U1 and am having issues getting the task sequence to format the drive again after the drive was encrypted with BitLocker.
I've read on multiple sites that Windows is able to install right over a BitLocker'd drive through PE without needing to disable BL through windows first if the partitions are gone. As such, I've setup the following to run in diskpart prior to the Partition
Disk 0 - BIOS step:
select disk 0
select partition 1
delete partition override
select partition 2
delete partition override
exit
This works, however the Partition Disk 0 - BIOS step fails at formatting C: with
Error 0x80070057 The parameter is incorrect.
It formats the system reserved partition just fine, but leaves the remainder of the drive as "raw" and usually unreadable by diskpart which requires me to boot to gparted to delete the partitions on the drive to do anything with it again.
I've:
verified SCCM boundaries
tried assigning a variable to save the drive letter to
disabled quick format
disabled all Bitlocker steps
disabled the diskpart steps I added
format the drives prior to the task sequence with:
Select Disk 0
Clean
Create Partition Primary Size=350
Active
Format FS=NTFS Label="System Reserved" Quick Override
Assign Letter=S
Create Partition Primary
Format FS=NTFS Label=OS Quick Override
Assign Letter=C
Nothing will get the SCCM task sequence past this. This happens for both Windows 7 and 8.1 task sequences.
What's interesting is, if I load up the Windows 7 media via flash drive and install through that, Windows installs without issue. I've then been able to bitlocker the drive and unencrypt it as expected. Attempting to run the task sequence after this results
in the same error.
My question is, what is different between the default windows installer and the windows install through SCCM when it comes to partitioning the drive and how do I get the SCCM task sequence to match the default Windows install process so this will install?

I've tried with that and numerous other labels and it still fails.
If I've gotten Win7 / 8 installed through the default media, it seems like the drive can be partitioned correctly and working fine. When the "Partition Disk 0 - BIOS" task runs, SCCM doesn't give me the ability to specify the exact diskpart commands; it
sorts that out on its own. The diskpart commands above were my troubleshooting steps. SCCM wipes them away once the Task Sequence runs.
There's something that SCCM doesn't like about drives that have been bitlocker'd and not properly unencryped through the OS prior to wiping the drive.
Does the default Windows 7/8 media run different diskpart commands during install than SCCM would run for install? One works - the other doesn't.
Below are the settings that are configured for this step - which I believe are default for an auto generated task sequence.

Prohibitory Sign, Can't sign in to computer after software update

I have a MacBook Pro 13" inch, mid 2012. I updated some of my software, (I believe it was Safari, maybe a security update, and maybe a startup update?) I can't really remember, but they were all relatively small and I figured they would be quick updates. Once it updated and told me to restart, my computer will not properly start up at all. I get to the user login screen, type the password, then the apple logo shows up for a few seconds then goes to the prohibatory sign on the gray screen with the spinning gear. I left my computer plugged into the power cord all night and when I woke up it was still doing the same thing. I've held down the power button to hard restart it multiple times, tried to restart in SafeMode, but nothing changes when I hold down "shift" or "shift-command-V"
I CANNOT lose my files.I have so many documents from my entire 4 years of college on there that I've spent countless hours working on and perfecting.
PLEASE Tell me this can be an easy fix?!?!

Mac OS X- Gray screen or prohibitory sign appears during startup

Prohibitory sign during boot, after update 20.03.2015

System Yosemite last Version, HW MacPro 3.1.
After the in AppStore recomendet update yesterday (20.03.2015) the boot stops with a gray prohibitory sign.
All by Apple described help did not help.
The last option would be re-install. But then how install donloaded Yosemite - will be an other question.

Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

Mysterious disk with the same name and a prohibitory sign

I installed a hard drive named "Storage" at the optical drive of my MacBook Pro as a data drive (startup drive is "MBP2012"). Sometimes when I login the disk becomes "Storage 1" (although it shows up as "Storage"), and all the applications that automatically access data on Storage won't be able to find them. I go to /Volumes/ and find that there is a "Storage" disk already mounted before my real Storage disk, with a prohibitory sign:
Deleting the "Storage" with the prohibitory sign would bring my mac back to normal, but it happens again after a few days.
Anyone can help? Much appreciated.

A schema is just a collection of objects owned by a particular user. So you don't need to create a separate schema-- the schema is automatically created when you create the user.
In order to log in to the database, a user needs the CREATE SESSION privilege. In order to create a table, the user needs the CREATE TABLE privilege and needs to be granted enough quota on whatever tablespace the table will be created in. If you don't care about managing quota or restricting the tablespaces that a user can create tables in, you can grant the user the UNLIMITED TABLESPACE privilege. If you do care about managing quota, you'd need to run commands like
ALTER USER <<user name>>
QUOTA <<quota amount>>
ON <<tablespace name>>for each tablespace you want the user to be able to use.

Disk utility wont resize/add/delete a partition (HD is part of a raid)

I have two SSD set in a raid 0 in my MBP 15" late 2011 (Mountain Lion 10.8.2)
256gb Samsung
120gb Vertex 3
My Vertex 3 is partitioned into 2 parts
1. 70gb set in raid 0 with another 70gb partition in the Samsung
2. 50gb dedicated to Windows 7
My Samsung is partitioned in to 2 parts
1. 70gb set in raid 0 with the other 70gb partition in the Vertex 3
2. The rest of the space in this SSD is just for data storage.
The reason why I did it this way is a long story since it deals with issues in the optical bay SATA speed limitations so that's a different topic.
So here is my problem:
I have two 70gb partitions set in raid 0 between the two SSD's, the 50gb partition that was in the Vertex 3 dedicated to Windows. After a while I realized I dont use windows that much and wanted to erase that partition. Erasing it was easy, but now with the 50gb space left over I try to use disk utiility to divide the 50gb partition into 2 parts and it wont let me. The satus bar says "preparing to partition disk" for 30 minutes and it doesnt budge.
To make matters worse, I deleted that partition by clicking the minus sign on the lower right corner, and now that partition is completely greyed out. When I try to press the plus sign to add in the remaining free space in my Vertex 3, it wont let me. The satus bar says "preparing to partition disk" for 30 minutes again and it doesnt budge.
Does the 70gb raid partition in the Vertex 3 prevent disk utility from making further changes to the Vertex SSD? I am pretty familiar with disk utility and know my way around it but I have my hands tied in this situation. Please help!

Things I've tried:
1. Booting from an extenral HD with Moutain Lion and trying to use DIsk Utility to make changes to the Vertex 3 partition, same thing occurs (it hangs for 30 minutes with no progress).
2. After I deleted the 50gb partition from the Vertex 3, it is now greyed out. Now when I try to press the add sign in disk utility to add back that 50gb empty greyed out space to make it for free storage (choosing Mac OS Extended, journaled), SAME THING HAPPENS.
It seems as though once I deleted that partition from the Vertex 3, that 50gb space is now totally unuseable!
By the way, I dont have filevault activated if that info helps at all to diagnose it.
