Index on disk

how does an database implement index to accelerate findings of like where name>"b" and name<"f" and location>"r" and location<"t" in disk files?
e.g I have a file,which can't fit into memory ,contains records of a corporation employee info in fomat like this: name, birth ,location,salary.
I wanna compute sum of salary given any restriction like where name>"b" and name<"f" and location>"r" and location<"t" or where age>25 and age<35 and location>"h" and location<"k"
Any hint would be appreciated.

jame,
Is problem related to grid or spatial indexing?

  • Allow indexing service to index this disk for fast file searching

    Hello,
    I'm using Oracle on Win 2000, I have lately found out that the option "Compress drive to save disk space"
    is not supported in Oracle.
    When I've opened the drive specifications on the properties dialog, I found also another option called "Allow indexing service to index this disk for fast file searching".
    My question are;
    1. Should I turn it off?
    2. Same question when the indexed directories does not include Oracle files?
    3. Same question, when the indexing service is set to off?
    Thanks,
    Tal Olier ([email protected])

    If this is a production machine, I'd definitely turn this off. Hopefully, no one is going to be searching for particular files on a production server-- they'll know where to go. You probably don't want any unnecessary background processes using up CPU or RAM either.
    If this is a development machine, the developer may be searching for files with some frequency. If that's the case, it may be worth it to keep this service enabled.
    I'm not aware of any Oracle issues when this service is running, but I'm paranoid enough not to trust it on a production box. If you're running on a dev box, you shouldn't have problems, particularly if you're not indexing Oracle files.

  • TM on Drobo returns Error "Flushing index to disk returned an error: 0"

    Hi, I'm using a sparse bundle on a Drobo (Drobo with Drobo Share / Drobo Dashboard) to back-up my Mac via TM together with TimeMachineEditor V2.5.3(26) to modify the schedule to only once a day. Since 4 months this just worked fine.
    I'm also using the same Drobo to back-up my wife's Windows PC without problems.
    Since July 1, back-ups of the iMac come back with the following error:

    I still access the Drobo without difficulties, see the old back-ups, there is more than sufficient space, the Windows back-up continues to work ...
    Any idea what might be wrong ??

    Thank you, Pondini, for insisting to go back to the other thread and try everything there. In fact, what I got wrong at first try was that I tried to look into the Sparsebundle (inspect contents) where I couldn't find the .Spotlight-V100 folder. After that I opened the Backup Volume of my iMac with Finder (having switched on hidden files before via TinkerTool) and - voilá - found the .Spotlight folder and canceled it. After that a first backup ran OK in rather short time. Thereafter the next backup took almost 2 days constantly saying: "Indexing Backup", but at the end it terminated successfully. So, everything seems to be alright now. And my old back-ups are still there :-))
    Yay!
    However, to be honest, I still do not understand this behaviour of TM. For me it looks like a bug. If the .Spotlight-V100 folder causes the problem, and you can correct that by simply canceling the folder, why can't TM simply "disregard" the folder, or cancel it automatically ??
    This is quite unusual. Corrupted files can make computers do all sorts of odd things. Clearly there was something very wrong in that index; +*Repair Disk+* can find many things, but not all. It will find problems in the various directories and catalogs that keep track of where files are. It may not find things that are wrong inside a file.

  • Error: Flushing index to disk returned an error: 0

    I just had a full backup of a newly installed drive fail very near the end with this following message:
    9/22/10 9:40:30 AM com.apple.backupd[1069] Error: Flushing index to disk returned an error: 0
    What is error 0?
    (FWIW, Disk Utility says the TM volume is OK.)

    Hi Pondini!
    Thanks for the informative response. Unfortunately, by the time I got it I had already deleted the .inProgress file and started from scratch. Turned out to be the right thing to do. I'm still not 100% sure what happened, but this is the best I can figure:
    1. I bought a new computer and set it up by restoring from my most recent TM backup of my old computer.
    2. I set up a brand new TM volume on an external drive (connected via a Spyderhub, though I don't think that made any difference). TM did a full backup of ~90GB which took about 10 hours.
    3. I then cloned the original hard drive in the new computer using SuperDuper onto an SSD.
    4. I swapped the SSD for the original drive.
    5. In order to be able to plug in the old hard drive as a backup without the system getting confused by having two volumes with the same name, I changed the name of the SSD. In retrospect, I think this was my mistake.
    6. I ran TM and it stared doing a full backup, which ultimately failed. I wasn't tremendously surprised that it was doing a full backup, since I had changed the name of the volume.
    Here's where it really starts to get interesting.
    7. I ran TM again as you suggested. As you predicted it was apparently very slow, taking many many hours to back up a few hundred MB. Before it was done I observed that the .inProgress file had doubled in size. It was now 160GB, but it was only backing up up 90GB. (The whole SSD drive was only 128GB.)
    8. I decided that TM was hopelessly confused and deleted the .inProgress file. It took over an hour to get rid of it. I also renamed the SSD back to the original volume name and started TM again, hoping that it would just do a regular incremental backup.
    9. TM appeared to be doing a full backup. So I stopped it, deleted the new .inProgress file, and renamed the SSD back to the new name. I figured that as long as I was going to have to do a full backup anyway I might as well have the drive named what I wanted it to be named.
    10. I started TM yet again, and again it appeared to be gearing up for a full backup. But it didn't do a full backup, it just did an incremental one. I'm guessing that just having the drive renamed back to its old name for even just the beginning of a backup cycle was enough for TM to figure out that the it was the same volume even after it was re-renamed.
    So I now have a fully synced up time machine again and all is right with the world.

  • Keeping Spotlight from indexing external disks

    Is there a way to exclude ALL external disks from being indexed by Spotlight? I don't need the indexing and it just slows everything down. I know about the list of exclusions, but a disk seems to have to be attached before one can exclude it. Can't one just keep it from indexing anything one might attach?

    Vaughan Schlepp wrote:
    Can't one just keep it from indexing anything one might attach?
    I don't think there is a simple (if any) way to do this, but note that the OS does somehow keep track of excluded disks once they are excluded, even when they don't show up in the list because the drives are not currently mounted.
    Perhaps there is some way to edit that list before mounting new drives, but I don't know where the list is or how to edit it.

  • Indexing of encrypted disk images permanently disabled in 10.8?

    In the past, I've had no trouble forcing Spotlight to index my encrypted disk image, using the command in Terminal:
    sudo mdutil -i on /Volumes/Encrypted_Data
    After entering that command, my encrypted disk image was indexed and searchable using Spotlight.
    A couple weeks ago I updated from Lion to Mountain Lion. Today I noticed Spotlight wasn't showing any results from my encrypted disk image. So went back to Terminal and entered the above command. Instead of successfully activating indexing, Terminal gives me this message:
    /Volumes/Encrypted_Data:
                Indexing disabled.
    Is this procedure now impossible in Mountain Lion?
    Is there any way to enable indexing of this encrypted disk image? I can't get it to work.
    Thanks.

    I appear to have solved the problem to get Spotlight to index a disk image.  My image was an encrypted disk image.  I was able to get spotlight to work when it was new, but now Spotlight won't index it.  Here is the solution that I found:
    After double clicking and mounting disk the image, open Disk Utility, select the disk image file, then click unmount in the Toolbar.  Wait until it is unmounted, then click mount again.   Then go to terminal and try mdutil -sa .  If it is still not enabled, try to sudo mdutil -i on option.  The unmounting and remounting must be done everytime the image is opened.

  • Disk Utility erase tab for hard disk is missing after accidental OS deletion when installing Win 8.1 (BootCamp)

    Hi there everyone,
    This is my first post and I hope I can get this issue resolved with your help .
    So the issue that I am having is that my Disk Utility is not showing giving me the option to reformat my entire hard drive.
    The reason I want to this is because my Boot Camp Assistant won't partition my drive. This error comes up:
    So after looking through the internet and forums i couldn't resolve this Boot Camp issue. So I decided to try and just wipe out my whole disk but as you can see I am unable to do that.
    Prior to this issue, I had tried to download Windows 8.1 using a bootable USB stick and have accidentally deleted my Macintosh HD partition from the Windows install menu by opening up a terminal (fn+option+F10 was the key used to open up this terminal if I remember correctly).  I was pretty upset about that, thankfully I have a backup around. Not knowing what to do I proceeded to installing Windows 8.1 anyway. Half way through the installation there was an error which I did not record. I simply exited the installer and proceeded to the Recovery System start up menu and it installed a version of OS X Lion from the internet. Then I installed Yosemite thinking everything is OK.
    I decided to try to install Windows 7 now and the issue mentioned at the beginning ensued. Previously there was a disk0s1 and disk0s2 that can be seen from the Disk Utility but I could delete one of them. The other one I could only erase but could not delete the partition itself. From terminal i determined these two partitions were from the previous Windows installation attempt. The size was relatively small for both.
    I ran a disk repair for the Macintosh HD volume and this error pops up:
    I am using MacBook Pro (15-inch, early 2011) with:
    2.2 GHz Intel Core i7

    Please boot into Internet Recovery (Command+Opt+R) and ensure you see the spinning globe. If you do, you can use diskutil cs commands to initialize your disk and re-install/restore from a TM backup.

  • After performing a clean install, is my startup disk correct for apple stock 1TB fusion hard drive?  I think I may have to reformat.

    After performing a clean install on a stock apple 1TB fusion Hard Drive it appears as things got reversed and showing my startup as not using the SSD portion.  The SSD portion of the fusion drive used to be on top in disk utility, now its on the bottom.  It also appears that I have to many partitions.  Im thinking i need to reformat my Hard Drive again.  I can't seem to find any answers.

    Hi,
    According to your descriptioin, I don't think this is system problem, it should be Intel driver problem. It would be contact Intel to confirm this issue whether this is their driver problem.

    It appears as if my startup disk has been reversed and not using the fusion ssd portion as it should.  At least its now reversed as to what it used to be originally before.  the 128gb ssd used to be on top.  Is my mac booting fusion correctly?  Thank you for responding as I was about to reformat.

  • Lost the ability to Spotlight Index my Time Machine drive

    I have an external, Firewire Time Machine drive which has been working without problems up to now. This evening I had a backup which hung up in the "preparing" stage (no file transfers begun yet). When I went to look in the console, there was a device error apparently related to trying to detect the powered-on state of my Time Machine drive. Apparently Time Machine did not handle this gracefully. In the course of trying to clear that I got into a state where I had to force shutdown of the system (holding the power button). (I accidentally clicked on the Time Machine icon which got hung up trying to display the histories, and left me with no access to the Desktop....)
    Things appeared to check out fine when I brought the machine back up (including Verify Disk of both the main and Time Machine drives and Repair Permissions of the main drive), and I finally did a Back Up Now in Time Machine. Due to the forced shut down, this became a "Deep Traversal" "preparing"stage. We'll I've seen those before, so no worries. However it lasted quite a bit longer than it should, at which point I noticed that Spotlight was indexing the Time Machine drive.
    So at this point I dragged the Time Machine into the Spotlight Privacy list. Rather than going away completely as I expected, the indexing of the Time Machine drive apparently went into some sort of clean-up phase that said it was still indexing for another 5 minutes (where it had, just prior, said it was going to be indexing for another 2 hours). The progress bar advanced normally as if it really did do 5 minutes more of indexing of the Time Machine drive. I've not seen this before
    When that finished, the backup which had been "preparing" during all of this also finished "preparing", transferred the several MB of files I expected, and finished normally. There were no errors in the console related to any of this.
    I rebooted, and once again did a pair of Disk Verifies and a Repair Permissions without problems. Opened up the console to track things, and poked around in the Time Machine. All was normal as far as I can tell. I also explored the Time Machine drive via the Finder. No problems.
    So I now went into Spotlight Privacy and removed the Time Machine drive from the privacy list expecting it to do the re-indexing I had stopped above. Spotlight started indexing the drive and a couple seconds later it stopped. I tried again -- into and out of privacy -- same result, a couple seconds of indexing and then it stopped.
    At this point I noticed the console was saying I had some bus errors in the I/O system, and that's what was terminating the md worker process and stopping the indexing.
    So I shut down, unplugged the Time Machine drive, and went through my maintenance ritual.
    I reset the PMU (this is a powerbook), reset PRAM, booted once in Safe Mode, booted normally, and ran Disk Utility again to Verify and Repair Permissions on the main hard drive. All of that went without a hitch. No failures, faults or funnies.
    I ran through the list of Applications I use, keeping an eye on the console. Again no problems.
    So I shut down, plugged the Time Machine drive back in and booted back up. I put the drive into Spotlight Privacy and turned off Time Machine backups. I then did a Verify Disk on that drive. No problems. I went into the Time Machine history display. No problems. And no problems looking at it in the Finder either. In particular, no bus errors or anything else funny in the console.
    I rebooted and did a new Back Up Now. It completed without problems. It was another Deep Traversal backup due to the Safe Mode Boot, but it went without a hitch. I rebooted and did another Back Up Now and got a normal speed incremental backup again without a hitch. The bottom line is that as far as I can see that Time Machine drive is working just fine.
    So I went into Spotlight Privacy and removed it from the list. Once again it started to index and stopped in a couple seconds. But this time there were NO Console error messages.
    I moved my main hard drive into Spotlight Privacy and removed it and it re-indexed from scratch just fine. Tried again with the Time Machine drive -- indexing stopped in a couple of seconds with no message in the Console. Spotlight searches find all the right stuff in the main drive. Spotlight and finder searches find only the top level Time Machine folders in the Time Machine drive.
    I also tried removing the Spotlight plist from my account's Library / Preferences. Spotlight created a new plist as expected but it still won't index that darned Time Machine drive.
    Apparently there is something left over from when I originally aborted the Spotlight indexing of that drive which is causing Spotlight to think it has no work to do. I'm not seeing any I/O errors of any sort any more (I think my maintenance pass took care of that) and Time Machine backups and history access continue to work just fine. And again, the Time Machine disk Verifies just fine.
    So I've run out of things to try.
    Is there a hidden file that I need to remove from that drive so that Spotlight no longer thinks it already has it indexed?
    --Bob

    Well unfortunately the command
    sudo mdutil -E /Volumes/MyDiskName
    didn't help.
    The command itself echoed the name of the volume and then said "Indexing Enabled", which looked good. But the Spotlight indexing stopped after a couple seconds. The Console reported the Terminal sudo command and nothing else.
    I tried moving the Time Machine drive in and out of Spotlight privacy and once again the indexing started and stopped a couple seconds later with no Console messages.
    I then tried another trick I've learned to make Spotlight indexing happen which is to do a Finder search for, say, all folders (limited to the one drive) via Command-f and while Including both System Files and files both Visible and Invisible. And indeed Spotlight indexing started but again stopped a few seconds later.
    However, this time there were console messages and a crash report.
    The Console shows (with personal information x'ed out):

    Apparently the mdutil command didn't actually delete the Spotlight index file which is causing the problem, or at least didn't leave the indexing files in a consistent, empty state to start indexing over again. I may have to Erase this Time Machine disk and start over.
    I should point out that except for Spotlight indexing this disk is otherwise working just fine. It passes Verify Disk with no errors and both new Time Machine backups and viewing and restoring via Time Machine and Finder work without problem.
    Any suggestions before I just Erase the disk and start over with a new backup?

  • Disk space used much larger than actual files

    I noticed this morning that Terminal was giving a warning about running out of swap space, which I thought was odd, as /var/vm was only at around ~10GB, but later when I tried to install some updates, I noticed that it said I only had 1.8MB free on my hard drive. I ran a df -h and it showed %iused at 100%. I immediately deleted some logs to free up a few megabytes of space and started hunting for what could have been hogging all my disk space, I seem to remember having 60GB free last time I checked. I was deleting a few small files, when I noticed this
    bash-4.2# du -h -d 1
    6.2M          ./.DocumentRevisions-V100
    584K          ./.fseventsd
    583M          ./.Spotlight-V100
      0B          ./.Trashes
    31G          ./Applications
    2.1M          ./bin
    20K          ./cache
    3.8G          ./data
    5.0K          ./dev
    34M          ./Developer
    1.3M          ./EFI
    1.0K          ./home
    8.9G          ./Library
    1.0K          ./net
      0B          ./Network
    185M          ./opt
    12G          ./private
    1.5M          ./sbin
      0B          ./Shared Items
    4.1G          ./System
    52G          ./Users
    4.9G          ./usr
    4.0K          ./Volumes
    117G
    So apparently, according to du, I am only using 117GB of my hard drive. I immediately ran this
    bash-4.2# df -h
    Filesystem      Size   Used  Avail Capacity  iused   ifree %iused  Mounted on
    /dev/disk1     297Gi  283Gi   14Gi    96% 74220526 3630455   95%   /
    devfs          200Ki  200Ki    0Bi   100%      692       0  100%   /dev
    map -hosts       0Bi    0Bi    0Bi   100%        0       0  100%   /net
    map auto_home    0Bi    0Bi    0Bi   100%        0       0  100%   /home
    So my question is how is it that all of my files combined are using 117GB, including swap, but according to df, Disk Utility and Finder I am using 283GB? I am using FileVault 2, if that helps
    Here's some more data

    The 300GB partition is the partition I am booting off of, and the one I was writing about. Disk0s1 is the EFI partition, 210MB. The other Internal hard drive is the core storage physical volume, already mounted, mounted in the image. Recovery HD is the 650MB system recovery partition.
    I rebooted to the recovery partition and used Disk Utility to verify the volume, it said everything checked out alright.
    In disk utility, the top entry has this data
         Name :     Internal Hard Drive     Capacity :     319.21 GB (319,213,174,784 Bytes)
         Type :     Logical Volume Group     Available :     16.8 MB (16,777,216 Bytes)
         Disk Status :     Online     Used :     319.2 GB (319,196,397,568 Bytes)
    However the other entry, right below it has this

    So I guess the reboot fixed my problem, df -h now shows 37% used, but the logical vomume group still shows only 16MB free. Anyways, things seem to be working now.

  • "No bootable device --- insert boot disk and press any key" after setting up Bootcamp

    Hi guys,
    I am trying to install Windows 7 via Bootcamp but after setting up Bootcamp and restarting the computer I get the error message "No bootable device --- insert boot disk and press any key".
    I use an iMac with a DIY Fusion Drive consisting of a 120 GB SSD and a 1 TB HDD.
    Since Bootcamp can only be installed on the HDD I believe disk1 is the interesting one. Here is the output of sudo gpt -r -vv show disk1:

    I have gdisk installed and am ready to mess around. Any help would be greatly appreciated!

    So, when I started my iMac yesterday morning it couldn't boot into OS X anymore either. Several hours of restoring later I am back to square one. I tried installing Windows 7 via Bootcamp again but got the same error message. This time I noticed though that Bootcamp asked me to remove the bootable option from the USB drive with the support drivers in order to install from DVD. Does that ring any bells? I am building another USB drive right now, hoping it would ask me again but this I will decline and try to boot from it.
    When you restored, was a Time Machine restore used? TM does not backup Bootcamp and does an erase of the partition. It may also erase the entire disk (including the Fusion drive) if the specific backup of the volume layout of the disks indicates a pre-Bootcamp layout.
    My MacBook Pro is a 2009 model and also once had a built-in optical drive. I have no idea why it would work on there but not on the iMac.
    You also wrote
    When I plug the external DVD drive in, the boot manager recognizes a "Windows" disc and an "EFI Boot" disc. If I select the "Windows" disc I get a black screen with a blinking dash.
    The blinking dash indicates that it is working, but does not have the requisite drivers to enable the GPU/Mouse/Keyboard on the media being used.
    In the MBP case, did you have two drives installed in the MBP, a Fusion configuration, and then were able to successfully install Bootcamp?
    For example on a Mac mini I have a DIY Fusion drive, but the sequence was done differently. Bootcamp was installed using a USB stick+Windows 7 ISO.
    1. The two disks are not in a CoreStorage set up initially.
    2. The second disk is partitioned (64Gb) and a Bootcamp W7 install completed via USB (this is different HW as compared to IMac, because it has no Optical drive).
    3. After the HDD is partitioned, the first partition and the SSD are then used to create a CoreStorage volume.
    4. Here is the working version and disk layout. (I plan to erase both disks, put W7 on a partition on the SSD, and make the non-Bootcamp+entire HDD in a CoreStorage volume).

  • Time Machine does not cope well with nearly-full disk

    Although Time Machine is supposed to delete old backups when the disk fills up, under some circumstances it does not cope well with a disk-full condition.
    Hardware: iMac (mid 2007)
    OS: Mac OS X version 10.6.8 (Snow Leopard)
    Processor: 2.8 GHz Intel Core 2 Duo
    Memory: 2 GB 667 MHz DDR2 SDRAM
    The other day I noticed that I had not had a successful Time Machine backup in over a day. Backups were taking a long time to run (4 hours or more), during which time the backup disk was chattering constantly and the disk showed "Estimating index time" in the Spotlight menu (even though I had excluded the disk from Spotlight indexing). When the disk finally stopped chattering, the backup finished with no visible errors but Time Machine continued to state that the last successful backup was yesterday. The backup disk was nearly full, but I had assumed that Time Machine was designed to cope with this situation by deleting old backups.
    A complete annotated log file of the incident and my observations can be found here: http://bentopress.com/backup.log.zip
    Here are some of the interesting entries from the system.log file:

    Sep  7 16:26:15 Bento-iMac com.apple.backupd[56515]: Backup canceled.
    Note the "error: 0". Error code zero normally indicates success.
    There were also many, many, many copies of the following message, which occurred while Spotlight was trying to index the backup disk:
    Sep  7 17:28:40 Bento-iMac com.apple.backupd[58064]: Waiting for index to be ready (100)
    Here's what I think is happening: at the very end of the backup, after the files have been copied to the backup disk, mds resets indexing because the disk is now full. backupd's attempt to flush the index to disk then fails because indexing is suspended (error zero), so the backup is canceled. I suspect that this may occur when the new backup and the old one(s) being deleted are both small enough that the disk "packs" tightly, leaving no room for the index. If a large (>500MB) old backup had been deleted to make room for a small (<100MB) new one, the problem would not have occurred.
    I worked around the problem by switching Time Machine from the full disk to my Time Capsule. (I did not have this system backing up to the Time Capsule originally because I purchased the Time Capsule later for a different system.) The downside of this is that I lost access to older backups (though they are still accessible by right-clicking on Time Machine in the dock and selecting "Browse other Time Machine disks..."—however, I have not actually tried this). I'm also not completely happy having both my main systems backing up to the same hardware, but everything seems to be working well at this point and I do have a secondary backup system, using SuperDuper to clone the systems' disks to an external HD, which I do about once a month.
    Although I have worked around the problem, I am posting this in the hope that it will be useful to someone else, in the hope that someone at Apple will notice and perhaps improve the performance of Time Machine in this situation, and also in the hope that someone can suggest a solution that does not involve throwing a bigger disk at the problem. Is there any way to free up space on Time Machine's backup disk, for example by manually pruning older backups, either through Time Machine itself or via the Finder or command line?

    If you suspect that the disk being full is the problem, have you tried deleting some of the old backup data on the TM disk?
    When in TM, go back to the past a long way, right click on a file/directory and select "delete backup". Do this on some big files you have (so that you get more space per removal) that you change all the time (so you'll still have recent backups).

  • "Non-system disk Press any key to reboot"- Trying to install Win 7 on Mac Mini

    Hello. I'm trying to install Windows 7 on a new-model Mac Mini ('Late 2012'), which I just bought from Apple. [Specs: 1 TB Fusion drive, 2.6 GHz intel Core i7, 16 GB RAM, OS X Mavericks (latest), Graphics: Intel HD graphics 4000, Screen: LG Flatron 24"].
    After following instructions on Bootcamp, I tried installing it through my external USB Apple Superdrive (DVD), but for some reason as soon as the system finishes getting things ready and reboots to begin installing Windows 7, I get a black screen with an error message as follows: "No bootable device -- insert boot disk and press any key". Pressing the keys on my keyboard does nothing (even though it's a wired model, not a wireless one.) I'm forced to do a hard shutdown using the power button and hold down the Option key in order to get the system to show the Mac HD where OS X is. It also shows the Windows DVD as another option, but when I select it and the system boots, I just get the same error message again. So I go back to a hard shutdown and reboot to go into OS X again.
    Not sure what to do, I did some online research and in one post in the Frequently Asked Questions for Bootcamp, it says for installing Win 7 and Win 8, the computer won't work with external USB drives (*totally nuts in my opinion - Apple has to fix this stuff if they want to entice Windows users into buying their sleek, quiet hardware). Instead, the post recommends creating a Windows 7 ISO file from my Windows 7 DVD and putting it on a USB thumbdrive that Bootcamp is going to use to put all the Apple/Windows drivers on for the installation process. I'm also told I have to unplug my Superdrive (no explanation given for why). So I do all this and get Bootcamp Assistant running again. Unfortunately, as soon as the system reboots after going through all the usual preparation steps, I get another black screen with a new error message: "Non-system disk Press any key to reboot". So I'm at a loss for what to do next.
    (I've also have an iMac that I bought more than a year ago that I also put Windows 7 on, with no problems that time. Go figure.)
    If anyone here has an good answer for how to proceed, I need to know. Thanks in advance!

  • "Non-System Disk" Boot Camp Windows 7 on 5K iMac

    I've been trying to install Windows 7 as a Boot Camp partition on my 5K iMac for a few days now. It's driving me crazy.
    I've tried:
    Installing from multiple different USB devices – all USB 2.0, 16gb or 32gb. I've tried 4 different sticks now. I just tried a Sandisk 16gb as someone here pointed out none of theirs worked except their Sandisk drive, but no luck with that either.
    Using multiple different ISO's, all x64 – all Windows 7 but different versions (Home Premium, Professional, Ultimate). These are all downloaded from the Digital River sources.
    I contacted Apple Support and they advised attempting the Boot Camp setup while in Safe Mode. With this method, I was unable to even begin the process as the error message 'Must be Windows 7 or higher' comes up instead. I'm pretty sure this is just because I can't mount drives in Safe Mode.
    Here's what happens:
    Format the USB drive with 1 partition, set it to Master Boot Record, FAT32.
    Run Boot Camp Assistant.
    I leave all three options selected: create USB, download Windows software from Apple, and then create the partition.
    Select the x64 Windows ISO.
    Select the USB drive. Actually, there are no other drives connected, so it just auto-selects.
    Hit 'go'. Let it do its thing. It asks for a password twice during the process, and takes about 20 minutes.
    I then create a partition. I've been using 96gb, but have tried going up to 128gb to see if that makes any difference. Nope.
    iMac reboots when that's done. It sits there for a little while with the backlight on and a black screen, then shows "Non-system disk. Press any key to restart.".
    I hit my head on the desk a few times.
    I try restarting the iMac and bringing up the boot manager to see what disks are available. There's only one: Macintosh HD. No recovery HD, and no 'Windows' drive I've seen on some other posts.
    I restart the iMac and let it try booting normally again. This time, and all subsequent attempts, I get a "No bootable disk" error.
    At this point I find some sorta-relevant post that recommends trying something else, so I remove the partition and try that – a different USB, a different ISO (of the same thing). I do not have a disk drive of any kind and cannot use Windows that way.
    I've updated to the latest version of Yosemite, but that changed nothing. I've also tried inserting the bootable USB in my rMBP 13", but that doesn't show it as a boot disk either.
    Not sure if maybe I'm missing a step? I've been following Apple's step-by-step guide in their Support pages.
    If anyone has any experience with this problem, any advice would be greatly appreciated.

    Ok. I've created a Boot Camp partition, and WININSTALL is the USB drive I've created via Boot Camp Assistant.

    Thanks for taking a look at this. I haven't been able to find a Windows 8.1 ISO to try as I don't have a license for that, only Windows 7.
    Also, the USB stick I'm using now is a Sandisk Cruzer. I've seen it used elsewhere here with success, so figured it must be a suitable device.
    Any ideas of what else to try?
