Way to guarantee start-up from main disk?

Using OS 10.6.8 on a MacPro, I use SuperDuper to daily back-up and make a clone of my main Hard Drive to another internal Hard Drive. I also schedule my computer to automatically start up every morning. The problem is nine time out of ten the computer starts up from the main drive but occasionally it will boot from the clone. If I don't catch it, things can get messy real fast as I start altering what are essentially backed-up files.
So, the question: is there a way to insure the computer always, without fail, boots up from the main drive?

The only thing that could explain this behavior then is for some reason the backup is somehow coming on line before you primary drive and being found as the only available drive to boot from at the time it is needed. I would check the drives with Disk Utility and maybe move them to a different bay just to experiment.
By the way, instead of shutting down I recommend you just sleep your machine. That's what I do. Daily it wakes up to do it's backup and then goes back to sleep. Everything is basically off anyhow when the mac pro sleeps. No fans, no drives. And then there is no need to boot when you need the machine.

"You Cannot Install OS X on This Disk. OS X cannot start up from this disk".

Hey, I am running Lion on a Macbook Air 2010 model and i recently bought Mountain Lion through the MAC App Store. ive had problems installing it as i cant install it onto my Macintosh HD (startup Disk). Ive opened the ML installer and its rebooted my mac into the installer Menu, but when it goes to install, it stops and says You Cannot Install OS X on This Disk. OS X cannot start up from this disk." i want to be able to install ML overwriting Lion on my MacintoshHD (startup drive), are there any solutions that can fix this problem?

Glad to hear it!
I ran into another problem: The USB cable I was using for my external backup disk was not reliable. I kept getting "disk ejects" at various points during migration.
I bought a new "2.0 certified" cable and it worked fine. The first two attempts resulted in re-installs.
I'm happy to report that after the 3rd re-install of ML everything appears to be OK.
I disabled TM and keeping my last b/u offline for a few more days to be safe....

Maverick upgrade issue : OS X cannot start up from this disk

Hi all, everytime I try to upgrade to Maverick for my new mackbook air, I got this problem 'OS X cannot start up from this disk' (MACOSX). I tried deleting files to get more space, repairing disk and determine that it is not time machine issue, but to no avail. I have 58 gb free space on my 128 gb SSD. Can anyone help ? It is really frustrating. I am not sure what is the other disk called OS X install ESD which is 5.42 GB total.

I'm trying to upgrade my tiger installation with leopard, but I get the message "Mac os x cannot start up from this volume". It is the internal disk and I have a Linux install too on that disk. Earlier I used Refit but I have removed it. Do I have to repartition? Partiontabel is GUID-partiontable in diskutil.
Removing an app or bootloader like rEFIt or OS such as Linux does not ensure that the drive is back to where it was before you installed these programs.
Even having a partition for TechTools eDrive will cause problems.
First I would run DU and check/repair your HD and then run a file permission verify/repair and zap the PRAM.
I would then suggest backing up Tiger and Linux with clones and completely erasing the HD using the full (not quick) erase and then installing Leopard and migrating your Tiger material back.

Mac os x cannot start up from this disk

I have a 2008 MacBook Air which runs Leopard. I want to upgrade to Snow Leopard and then Lion. I have the Snow Leopard family pack disk and try to do the install but it say 'Mac OS X cannot start up from this disk' and shows a yellow triangle with a !
I went to the genius bar and they told me to put the Snow Leopard disk in the superdrive and restart holding down C and it would then work - but it did not. I also saw on a forum about using disk utility and partion and resizing the partition then putting it back as it was originally and then re trying but I get the same message.
Anybody got any ideas?

Saw an article by Topher Kessler: http://reviews.cnet.com/8301-13727_7-10330520-263.html
The extract from that article below worked for me.
Note when I first resized the partion (comment above) I did not 'apply', this time I did and then resized back to the original full size and hit 'apply' again. Although when the install starts it shows the size of the partion to be the smaller (temporary) size, it is not and the install completes with no issues.
Boot from the Snow Leopard DVD and select your language. Then launch "Disk Utility" from the "Utilities" menu and perform the following steps:
Select your boot device (the device above the boot volume name), and select the "Partition" tab.
Resize the partition by selecting the volume name in the rectangular volume representation and drag the bottom-right corner of it to change its size.
Click "Apply" to change the partition's size.
Revert the change by dragging the same resizing corner back to the bottom, and click "apply."
After this is done, quit out of Disk Utility and try installing Snow Leopard again. Since you are booted from the Snow Leopard DVD you should be able to continue immediately without having to reboot your system.
Hope this helps others. Thanks Topher!

Most efficient way to delete "removed" photos from hard disk?

Hello everyone! Glad to have this great community to come to for help. I searched for this question but came up with no hits. If it's already been discussed, I apologize and would love to be directed to the link.
My wife and I have been using LR for a long time. We're currently on version 4. Unfortunately, she's not as tech-savvy or meticulous as I am, and she has been unknowingly "Removing" photos from the LR catalogues when she really meant to delete them from the hard disk. That means we have hundreds of unwanted raw photo files floating around in our computer and no way to pick them out from the ones we want! As a very organized and space-conscious person, I can't stand the thought. So my question is, what is the most efficient way to permanently delete these unwanted photos from the hard disk
I did fine one suggestion that said to synchronize the parent folder with their respective catalogues, select all the photos in "Previous Import," and delete those, since they will be all of the photos that were previously removed from the catalogue.
This is a great suggestion, but it probably wouldn't work for all of my catalogues since my file structure is organized by date (the default setting for LR). So, two catalogues will share the same "parent folder" in the sense that they both have photos from May 2013, but if I synchronize May 2013 with one, then it will get all the duds PLUS the photos that belong in the other catalogue.
Does anyone have any suggestions? I know there's probably not an easy fix, and I'm willing to put in some time. I just want to know if there is a solution and make sure I'm working as efficiently as possible.
Thank you!
Kenneth

I have to agree with the comment about multiple catalogs referring to images that are mixed in together... and the added difficulty that may have brought here.
My suggestions (assuming you are prepared to combine the current catalogs into one)
in each catalog, put a distinctive keyword onto all the images so that you can later discriminate these images as to which particular catalog they were formerly in (just in case this is useful information later)
as John suggests, use File / "Import from Catalog" to bring all LR images together into one catalog.
then in order to separate out the image files that ARE imported to LR, from those which either never were / have been removed, I would duplicate just the imported ones, to an entirely separate and dedicated disk location. This may require the temporary use of an external drive, with enough space for everything.
to do this, highlight all the images in the whole catalog, then use File / "Export as Catalog" selecting the option "include negatives". Provide a filename and location for the catalog inside your chosen new saving location. All the image files that are imported to the catalog will be selectively copied into this same location alongside the new catalog. The same relative arrangement of subfolders will be created there, for them all to live inside, as is seen currently. But image files that do not feature in LR currently, will be left behind by this operation.
your new catalog is now functional, referring to the copied image files. Making sure you have a full backup first, you can start deleting image files from the original location, that you believe to be unwanted. You can do this safe in the knowledge that anything LR is actively relying on, has already been duplicated elsewhere. So you can be quite aggressive at this, only watching out for image files that are required for other purposes (than as master data for Lightroom) - e.g., the exported JPG files you may have made.
IMO it is a good idea to practice a full separation of image files used in your LR image library, from all other image files. This separation means you know where it is safe to manage images freely using the OS, vs where (what I think of as the LR-managed storage area) you need to bear LR's requirements constantly in mind. Better for discrete backup, too.
In due course, as required, the copied image files plus catalog can be moved bodily to another drive (for example, if they have been temporarily put on an external drive, and you want to store them on your main internal one again). This then just requires a single re-browsing of their parent folder's location, in order to correct LR's records inside this catalog, as to the image files' changed addresses.
If you don't want to combine the catalogs into one, a similar set of operations as above, can be carried out for each separate catalog you have now. This will create a separate folder structure in each case, containing just those duplicated image files. Once this has been done for all catalogs, you can start to clean up the present image files location. IMO this is very much the laborious and inflexible option, so far as future management of the total body of images is concerned... though there may still be some overriding reason for working that way.

IMac G4 will not start up from OS disk to upgrade

I am trying to upgrade the OS in a G4 iMac, the OS disk is recognized, am asked to restart, but it will not restart from the OS 10.5 disk.

Will it boot from the install disc that came with the G4? If so, run
Disk Utility
   1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
   3. Click the First Aid tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Click Repair. Disk Utility checks and repairs the disk.
After that, reset the PRAM and see if that helps.
Please post back with results,

Start-Up from Install Disk with Complications

Originally I had start-up problems (flashing folders with question marks), so after troubleshooting, I started up from the install disk. After going through Disk Utility, nothing appeared in the First Aid for me to Repair the Disk. So the next step would be to delete the disk, and reinstall completely using the cds. However, I cannot find advice on how to do this, and don't see my hard drive on the Disk Utility bar to delete. When I try reinstalling the disk, it asks me where I would like to put the hard drive, and nothing comes up. I love my computer and am desperate - please HELP!

To start up from your OS installer disk 1 insert it in the Mac. When it appears on the desktop restart and hold down the 'c' key. If that fails there may be a problem with the disk or you are using the wrong disk. Until you get a new disk you can do repairs by restarting and holding down the command-s keys until you see the white scrolling text on a black background. Then at the prompt type:
fsck -fy
hit return. If it repairs something do it again until there are no repairs needed. Then type"
reboot mac
hit return

Can't start up from Install disk

I'm using a MacBook purchased 3/07. System 10.4.11
I can't start up from the Install Disk for Leopard. I only get a screen with the apple logo and the spinning thing. I wait 10 minutes. Nothing happens. I've tried both using the Disk for the start up and clicking on Install icons but when it shuts down to restart....nothing.
Can anyone help me?
Thanks. Lois

Hi Josef,
I left it on for over an hour and nothing happened. Finally called Apple and after an hour and a half of all kinds of testing, restarts, zapping and I don't know what else, the nice man there talked to his supervisor and then had me test the hardware (hold down D when starting). Turns out there is a problem with my ram so now I have to take it to a local technician and if he can't fix it, it'll have to go back to Apple for repairs. Ho hum. I just hope it finally gets working to make all this worthwhile.
Thanks again for your interest and help.

Why won't my iMac start up from install disk?

I get a gray screen, apple logo in the center with a spinning gear underneath it. I have started my computer holding the c key, the option key selecting the install disk and startup disk in system preferences. The iMac hangs every time. The hard drive is in need of repair.
thanks in advance
bradley

Funny you should mention that, as that happened a few months ago. When it did, I could still start up from the install disk, there was just no destination for the software to be installed. I am currently running the iMac off an external drive via firewire. Disk utility informs me that disk is now in need of repair, even though it seems to be functioning fine, I can't start my machine from the install disk without it hanging up.

Start up From Install Disk

I can't start up from my Mac OS X 10.4 install disk. I need to to do some possible disk repairs. When I follow the directions for starting form another disk, I fail to get the DVD as a start-up option. It only shows me the MacHD, which is my computer. One set of directions says hold down the option key, the other says hold down the C key. I've tried both.
Is there something I don't know about that could be interfering with the other start up option.

Best way to move redo log from one disk group to another in ASM?

Hi All,
Our db is 10.2.0.3 RAC db. And database servers are window 2003 server.
We need to move more than 50 redo logs (some are regular and some are standby) which are not redundant from one disk group to another. Say we need to move from disk group 1 to 2. Here are the options we are thinking about but not sure which one is the best from easiness and safety prospective.
Thank you very much for your help in advance.
Shirley
Option 1:
1)     shutdown immediate
2)     copy log files from disk group 1 to disk group2 using RMAN (need to research on this)
3)     startup mount
4)     alter database rename file ….
5)     Open database open
6)     delete the redo files from disk group 1 in ASM (how?)
Option 2:
1)     create a set of redo log groups in disk group 2
2)     drop the redo log groups in disk group 1 when they are inactive and have been archived
3)     delete the redo files associated with those dropped groups from disk group 1 (how?) (According to Oracle menu: when you drop the redo log group the operating system files are not deleted and you need to manually delete those files)
Option 3:
1)     create a set of redo members in disk group 2 for each redo log group in disk group 1
2)     drop the redo log memebers in disk group 1
3)     delete the redo files from disk group 1 associated with the dropped members

Absolutely not, they are not even remotely similar concepts.
OMF: Oracle Managed Files. It is an RDMBS feature, no matter what your storage technology is, Oracle will take care of file naming and location, you only have to define the size of a file, and in the case of a tablespace on an OMF DB Configuration you only need to issue a command similar to this:
CREATE TABLESPACE <TSName>; So the OMF environment creates an autoextensible datafile at the predefined location with 100M by default as its initial size.
On ASM it should only be required to specify '+DGroupName' as the datafile or redo log file argument so it can be fully managed by ASM.

[SOLVED] Is there a way to download package sources from main repos?

From AUR I can just do:
yaourt -G <PACKAGE> && makepkg -o
How do I download the sources from main repositories though?
Last edited by choosegoose (2015-02-08 08:42:02)

yaourt -G <PACKAGE> && makepkg -o (you need to cd into the downloaded directory first, but this is true with AUR packages too)
Or extra/abs.

Pass on Guarantee Start Date from manufacturer to repairer

Dear Sap Gurs,
My Client has requirement that after expiration of manufacturer's guarantee, the repairer guarantee start and end dates should be updated in equipment master data.
In this case how to track both manufacturer's guarantee and repairer's guarantee .
Please suggest solution to map this process.
Regards
Kiran Ambi

Hi Kiran
As a standard, you can assign two warranties to an equipment:
Vendor Warranty and
Customer Warranty
So you can use Customer Warranty as Repair Warranty.

Finder crashing constantly - cannot start up from install disk

Looks like I have a conflict between spotlight and the finder. The spotlight icon is missing from the menu bar and whenever I try to launch an application etc. from the finder it freezes & I get the spinning beach ball. The screen refreshes but the dock remains
I have done all the usual tasks like repairing permissions,repair the disk, rebuilding the memory with DiskWarrior, Mainmenu tasks , Applejack, restarting, Tech Tool Pro etc.
I have tried using the install dvd but I get to the restart page and it reverts back to where I was before and does not read from the DVD so I can't get to the installer. Have tried the disk in the internal and external optical drives without success.
I also can't seem to restore the system with Time Machine because it says to use the install disk which
my computer will not read from the disk.
Short of doing a complete erase, is there any else I can do.
The console is recording both Spotlight crashes and the Finder crashes every few seconds.
Anyone with some suggestions, please.
Alan

Because you have known good backups, I'd try to get the disks working and Restore from Backup via Installer as you were trying. Reseting the PRAM and NVRAM can help with startup issues (power down, wait 10 seconds, turn the computer back on and hold down commandoption+pr until you've finished hearing the second startup chime).
Let the computer startup. Power down and try to boot to the install disk.
If you still cannot boot to your install disk, try resetting your SMC by turning the computer off, disconnecting it from AC, removing its battery, pressing and holding the power button for 5 - 7 seconds, then letting go. Reconnect battery and AC, try booting to the disk again.
If both these steps fail, verify the disk with another computer - can another computer boot to it? If not, call AppleCare for replacement disks. If so, book a Genius Bar appointment, there is a hardware issue.

Adminstator password fails, can't start up from the Disk, etc.

I can not update any software or even make use of disk utilities. My password isn't accepted, even after starting in the safe mode and changing the password. My Administrator name doesn't appear as well. There is no start up ping. This all happened 5 days ago when I went to update the operating system. I have only been able to reboot from the startup disk once. The computer won't let me start up this way again.
Any ideas would be helpful.
I have removed all documents that must be saved onto an external hard drive. But, I can't even load a new system. I have tried various versions with no luck.

Thank you for your assistance.
I have tried this except for the last two steps. I left the start up disk stay in the computer and let it start up without holding down the "c" key. Ever since then I don't get the start up ping.
My son things there might be something wrong with the BIOS, but that is just more computer words to me.
I'm wondering if buying a new hard drive and loading the system in might be the easier and less frustrating way to go. I've also thought about loading the operating system on an external hard drive and start up with that hard drive to see what takes place.
Again, thanks for your assistance.
