• Unused Index Entries: What causes them?

  - by Bart Silverstrim

  I was running chkdsk on one of our servers and it fixed 800 unused index entries (minor inconsistencies) on the drive. I also see these on lab machines running Deep Freeze, where most drive changes are supposed to be prevented although I'm not sure of the mechanism through which it does this. The thing that got me more curious than usual is that this server does very little. Very little activity, it remotely serves out a web app with little use so it's rarely ever touched at the console...so what is it on NTFS drives that causes this? It seems to be treated as if it's nothing, but should this be happening on a barely used filesystem? Is it a sign of corruption? I would think it's something if a disk repair utility sees fit to report it and repair it. Maybe this is more curiosity while doing some routine maintenance on servers, but I'd like to know what this is doing and why it happens, if anyone can give insight on this phenomena.

• Windows undetectable after interrupted chkdsk

  - by Felthragar

  I have a computer that is running Windows XP. For some reason, the other day it wouldn't start giving me the following message: "ntoskrnl.exe is missing or corrupt" So I put the XP disc in the tray and fired up the repair console and ran the following: chkdsk /r It was on for about eight hours and it got to about 52% I believe. Then there was a power outage and the computer shut down (obviously). Today when I was booting it, it isn't even detecting there's an OS anymore. If I boot the computer with no cd in the tray it says: "Reboot and select a proper Boot device or Insert Boot Media in selected Boot device and press a key" If I run the repair console, or the xp installation program it isn't finding any OS installations. Any ideas on what to do next? Any help is appreciated. Thanks! Update: After turning boot-time diagnostics on, I got this message when booting without cd (instead of the previous one): "Couldn't open drive multi(0)disk(0)rdisk(0)partition(2)"

• outlook freezes on splash screen - loading profile

  - by sammarcow

  I have a user with a frustrating application crash issue without Outlook: Windows 7 x64 Outlook 2010 crashes on the splash screen with the message "loading profile." I have deleted the users .ost file in "..\AppData\Local\Microsoft\Outlook\" and this crash occurs for multiple users including those with administrator privileges. I have also tried running outlook at the command prompt as an admin with the /safe command-line switch. I tried the repair utility in "programs and features by clicking Change after selecting Microsoft Office:" ~~ Microsoft office failed to successfully repair your product . I tried to uninstall Microsoft Office ~~ Microsoft Office failed to successfully uninstall this product. I am trying to avoid reimaging the machine for obvious reasons. Is there anything else I can try or insight any one has on this issue?

• Requiring mulitple group membership in order to access folder

  - by David

  How would I go about creating a file or folder that requires a user to be a member of two or more different groups in order to read/write to the folder? For example, say I run an auto repair shop, and I have a folder called "Repair History" and I only want people to access it if they are members of BOTH the "Mechanics" and "Cashiers" group? This would be an AND requirment instead of an OR requirement which seems to be the norm. I know we can create a separate group that is needed to access the folder, but this is more of an academic question, since it pertains to a different security structure that we are creating. I'm not sure if MS security handles it, but I'm wondering how it would be done either way.

• WD Passport Won't Mount

  - by Scott7278

  My WD Passport won't mount. However, it turns on when plugged into my macbook and doesn't make any strange noises. It took a small fall (just a few inches and it was on my couch) and I'm very concerned about physical damage. When I open up disk utility it shows the root 500 GB WD My Passport drive which seems to be OK when I verify it and repair it. However, the "External Hard Drive", the directory underneath the "500 GB WD My Passport drive" is grayed out. When I verify the External Hard Drive it says it needs to be rapaired. When I try and repair it it gives me the following message and does not seem to progress: "Updating boot support partitions for the volume as required." Is there hope for me recovering my data? I stupidly have important data on it that I don't have anywhere else.

• dd cloned win2003 std ntfs partition, "no operating system found".

  - by 3molo

  I cloned an existing ntfs partition on faulty hardware using dd and gzip. The copied partition was then written to a newly created ntfs partition on a new disk (on another server) and the bootable flag was set. However, the "Operating system not found" (or is it No operating system found?) is what happens when I try to boot it.The faulty server is part of the AD domain, but I do not have the local administrator password, so I couldn't use the repair console of windows 2003 to fixmbr. I did try to do a normal repair during win2003 installation menu, but with no success. Both windows installation and Linux recognizes it as a ntfs partition of its true size, and files can be seen and read. I've done this a couple of times before, but I didn't encounter this problem. Of course I encountered other problems, like BSDO due to lack of hw drivers etc - but that was pretty easily fixed. Why am I failing to get the copied partition to even be recognized as a bootable disk on the new server?

• PowerPoint 2010 won't open any files.

  - by Samwho

  Recently I installed Office 2010 BETA on my friend's laptop after recommending it to her. The problem is, whenever she tries to open files in powerpoint it claims that there is a problem with them and it can attempt to repair them, when you click repair it just says there was a problem with the file and it can't open it. The exact same .ppt files work fine on my copy of PowerPoint 2010 (we sent the file from her laptop to mine via MSN) so I'm confused as to why they won't work just on her laptop. Any insight into this would be fantastic :) Thanks.

  - by user266969

  I have not found a fix. After running the Windows 8.1 Update from the store my computer will not boot unless In insert my recovery USB drive and try to repair. (The repair fails.) However after I power of the PC and remove the USB drive. The PC will boot correctly once. I would leave the PC on but it shuts it self off at night. (And yes I have checked my power profile, it is set to never.) The only thing I have found online is a possibly corrupt video driver. I uninstalled the video driver reboot and it did not fix the issue. Anybody have any suggestions? The PC is a HP EliteBook 8730w laptop. I had no issues with Windows 8 or the Windows 8.1 preview.

• A Windows Update Prevented Live Discs From Working?

  - by user88311

  First off I'll state my system specs. Acer Aspire M1100 Windows Vista Home Basic 32bit OEM 2 Gigs of DDR2 ram 160Gig hard drive 2.7Ghz AMD Athlon 64 processor ATI Radeon X1250 Graphics card A few days ago my computer did automatic updates and updated windows defender to KB915597 (Definition 1.135.415.0), After which when shutting down and starting up I would receive BSOD with the information BUGCODE_USE_DRIVER and 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x877330000) upon where my computer would not start up with any USB devices plugged in and it always require me to run startup repair before it started. Upon when I first started it up and was able to fully boot windows, I had no use of the mouse so I was unable to install the fix that the windows solutions center brought up on my screen, so I restarted again and installed the fix hoping it would cease the problem, it did not. Upoon starting up after installing the fix and restarting I was confronted with the BSOD 0x000000FE (0x00000008, 0x00000006, 0x00000006, 0x83291000) at which I found the startup repair could not fix the problem and I restored, as I most like should have in the first place. After going through that I read that simply installing the latest defender version from the microsoft site had fixed this problem for others, so I did that, to find I still received the BSOD's. So in a attempt to find a fix to the problem I went to the microsoft answers site to try to find a way to fix the problem, there I was told to simply disable defender and reboot to see if that fixed the problem, upon doing this my computer would no longer even startup, when I boot normally I get to just when the loading screen finishes and then my computer restarts and when I run startup repair, it runs for about 15 seconds and then my computer restarts as well. I have tried running ubuntu live discs in order to simply access the drive and simply copy and paste the 2 month old physical backup I have of my C drive to the C drive, but whenever I run the live OS when it gets to the end of the load screen and is about to boot, the computer again restarts, yet if I put in a gparted disc, I am able to boot it fully, although it does not give me access to the file system just partition managing and when I attempt to access the internet through it, the computer once again restarts. So my question is, how could the update and what has happened prevent me from running the live OS's properly?

• How to prevent boot manager missing after cloning a win764 image using Ghost 2003?

  - by hirogen

  I am running ghost 2003 command -fdsp, but once we have cloned the image and restored it onto exactly the same make and model machine, we are force to run win7 setup and run a repair which fixes the boot menu, I want to prevent this requirement to fix the problem, any suggestions besides the obvious of using Windows AIK tools, new versions of ghost/clonzilla. I want to prevent the problem in the first place, it's 1 partition only, on a levano workstation m82 with UEFI and a 100mb system reserved partition. Windows Boot Manager screen and states: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1.Insert your Windows installation disc and restart your computer. 2.Choose your language settings, and then click "Next." 3.Click "Repair you computer."

• Ubuntu 13.10 installed and worked, but now not working

  - by San

  I have a HP G7000 laptop. I updated/upgraded from 13.04 to 13.10, after the software updater recommended I upgrade. I have duel booting system with Windows Vista. The system was working for the past two days, but I start getting the errors below, after selecting Ubuntu in Grub Menu on startup and at the splash screen it says "Press S to Skip or M for manual configuration" Pressing S gives a black screen and m takes you the errors below. Windows boots and works fine after selection in the Grub Menu. [ 15.235703] EXT3-fs (sda5): error: unrecognized mount option "discard" or missing value.

(you can view the boot-repair log here http://paste.ubuntu.com/6287287) When I use the liveCD for 13.04 or 13.10 however, my hard disk is recognized and I can read the files. Why is it that the installation on the hard disk has stopped working and does not recognize my / ? What do the above errors mean and how can i solve them? There was no power failure before, during or after the update/upgrade process from 13.04 to 13.10. I now would like to go back to 13.04 without reinstalling afresh? Any help will be appreciated. Thanks.

• Are there Know issues with Ubuntu 11 and socket 1155? acpi=off

  - by James

  Since building my new system I cant get Ubuntu (or any other flavor of Linux) to "run" properly. To boot the live cd I have to "F6" and turn off acpi or the screen halts at a black screen with "boot stuff" written above the blinking curser. When installed I can only boot if I enter repair mode from Grub menu then once in repair mode I choose Boot Normally and it boots to the desktop. Once on the desktop I can "click" (with the mouse) only on one thing...like firefox or "desktop appearance" and the mouse no longer "clicks" on anything else ...its like the computer freezes but the mouse still moves. I end up using the reset button to restart the computer. I was able to update when prompted to do so....but at the end of the update I could not "click" the "finish" and had to use the manual reset button. I have run Ubuntu since v 8... My system specs are: intel i7 2600k ...Graphics disabled in bios... Asus p8z68-v pro.... 16G Kingston HyperX.... 2 EVGA GTX 570 in SLI.... Mouse is a simple Logitech usb Wireless. Ubuntu installed on secondary sata drive.

• Oracle Flashback Technology - Webcast 9th June 2010

  - by Alex Blyth

  Hi All Here are the details for webcast on Oracle Flashback Technologies on Wednesday (9th June 2010) beginning at 1.30pm (Sydney, Australia Time). The Oracle Database architecture leverages the unique technological advances in the area of database recovery due to human errors. Oracle Flashback Technology provides a set of new features to view and rewind data back and forth in time. The Flashback features offer the capability to query historical data, perform change analysis, and perform self-service repair to recover from logical corruptions while the database is online. With Oracle Flashback Technology, you can indeed undo the past! Oracle9i introduced Flashback Query to provide a simple, powerful and completely non-disruptive mechanism for recovering from human errors. It allows users to view the state of data at a point in time in the past without requiring any structural changes to the database. Oracle Database 10g extended the Flashback Technology to provide fast and easy recovery at the database, table, row, and transaction level. Flashback Technology revolutionizes recovery by operating just on the changed data. The time it takes to recover the error is now equal to the same amount of time it took to make the mistake. Oracle 10g Flashback Technologies includes Flashback Database, Flashback Table, Flashback Drop, Flashback Versions Query, and Flashback Transaction Query. Flashback technology can just as easily be utilized for non-repair purposes, such as historical auditing with Flashback Query and undoing test changes with Flashback Database. Oracle Database 11g introduces an innovative method to manage and query long-term historical data with Flashback Data Archive. This release also provides an easy, one-step transaction backout operation, with the new Flashback Transaction capability.

• Cannot see boot options after editing grub background

  - by cipricus

  After solving this problem I managed to get myself into truble again out of nothing by trying to change the display of the dual boot option page in Boot Customizer. I have changed the background, the fonts size (I have increased them) and font style (I have chosen UnDotum). But Boot Customizer gave me an error (I mean a message that the application was closed unexpectedly or smth). I have restarted BootCustomizer and the settings were there. When I rebooted, instead of the normal boot options list, just the background image that I had selected and nothing else. I used Boot Repair to repair grub, it says it did it successfully, but I still get the background image when I try to boot. Any ideas? (Could it be the matter that I chose UnDotum font style? That was installed in Lubuntu - but how could it be accessible in displaying boot options?) The contents of etc/default/grub are: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" I have tried to modify etc/default/grub: GRUB_HIDDEN_TIMEOUT=0 to 10 GRUB_HIDDEN_TIMEOUT_QUIET=true to false and GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "" but it doesn't help Also, using Shift doesn't make the list visible.

• Grub does not show a Windows 8 option after dual boot

  - by skytreader

  So, I've successfully dual-booted my Windows 8 machine with Ubuntu 12.04 . However, I still don't have a convenient method of choosing what OS to load at boot time. After installing Ubuntu, my computer still loads Windows 8 directly. I then added grubx64.efi to the white list of my boot loader. But after that, my machine loads Ubuntu directly without even a shadow of GRUB showing up! I used boot-repair and I got this paste.ubuntu URL: paste.ubuntu.com/1326074. After running boot-repair (and re-white listing the grubx64.efi file), GRUB now shows up but without any Windows 8 option! Lastly, I ran sudo fdisk -l and it gave me this: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 750.2 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x6396389f Device Boot Start End Blocks Id System /dev/sda1 1 1465149167 732574583+ ee GPT Partition 1 does not start on physical sector boundary. I'm guessing my problem has something to do with the warning from fdisk above but I don't know what to do with it. How do I proceed now?

• Cannot Create Bootable USB Drive from .iso file

• Windows 8.1 - unfixable grub

  - by Nick

  I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx

• "Misaligned partition" - Should I do repartition (how?)

  - by RndmUbuntuAmateur

  Tried to install Ubuntu 12.04 from USB-stick alongside the existing Win7 OS 64bit, and now I'm not sure if install was completely successful: Disk Utility tool claims that the Extended partition (which contains Ubuntu partition and Swap) is "misaligned" and recommends repartition. What should I do, and if should I do this repartition, how to do it (especially if I would like not to lose the data on Win7 partition)? Background info: A considerably new Thinkpad laptop (UEFI BIOS, if that matters). Before install there were already a "SYSTEM_DRV" partition, the main Windows partition and a Lenovo recovery partition (all NTFS). Now the table looks like this: SYSTEM_DRV (sda1), Windows (sda2), Extended (sda4) (which contains Linux (sda5; ext4) and Swap (sda6)) and Recovery (sda3). Disk Utility Tool gives a message as follows when I select Ext: "The partition is misaligned by 1024 bytes. This may result in very poor performance. Repartitioning is suggested." There were couple of problems during the install, which I describe below, in the case they happen to be relevant. Installer claimed that it recognized existing OS'es fine, so I checked the corresponding option during the install. Next, when it asked me how to allocate the disk space, the first weird thing happened: the installer give me a graphical "slide" allocate disk space for pre-existing Win7 OS and new Ubuntu... but it did not inform me which partition would be for Ubuntu and which for Windows. ..well, I decided to go with the setting installer proposed. (not sure if this is relevant, but I guess I'd better mention it anyway - the previous partition tools have been more self-explanatory...) After the install (which reported no errors), GRUB/Ubuntu refused to boot. Luckily this problem was quite straightforwardly resolved with live-Ubuntu-USB and Boot-Repair ("Recommended repair" worked just fine). After all this hassle I decided to check the partition table "just to be sure"- and the disk utility gives the warning message I described.

• Cannot boot after installing ubuntu on lenovo x120e

  - by tutysara

  I have installed ubuntu 11.10 on my x120e using amd64 alternate iso image. The installation went fine, but it is having issues while booting after a successful installation, it says - "No Operating System Found". I followed the instruction at - help.ubuntu.com/community/X120e#Installation to purge grub-efi and installed grub-pc, even then I couldn't boot into ubuntu.(got the same "No Operating System Found") This is the file from boot-repair with this setup - http://pastebin.ubuntu.com/926556/ Then I asked in #ubuntu and they suggested me to create a bios-boot partition, I was not very comfortable with the solution they had suggested but gave it a try anyhow. I re-sized my initial partition and made 4 MB free space in the beginning of the partition and had set the flag bios_grub. Re-installed ubuntu 11.10 this time using amd64 desktop iso image file. Installation went fine as before but finally this time also the system didn't boot, it gave the same - "No Operating System Found" message. In BIOS I have the settings as to use both (Legacy and UEFI) and with UEFI tried first. This is the boot-repair file from my latest setup - http://pastebin.ubuntu.com/926761 Any help/suggestions are appreciated.

• WUBI installation can no longer boot, UUID disk not found

  - by Joel Heenan

  Yesterday my Wubi/Vista installation was working fine. I shut it down at the train station, all good then when I attempted to boot ubuntu at home I got a message saying the UUID for root could not be found. By booting with the Ubuntu live CD I found that the C:\ubuntu\disks folder stat structure was broken, reported as "??? ??? ??" kinda thing. I booted into Windows, scheduled a CHKDSK, ran that on boot which found some errors and rebooted. Still no dice. I am not stressed because it appears my home directory is still there with all my content so I don't mind re-installing the OS (probably will clean it up some). What is the best path from here to repair the WUBI installation? Is there anything else I should do to repair it? I'm looking at whether the drive is dying now to work out why this occured. Possibly I moved the laptop before shutdown had completed.

  im facing a problem. after installing Ubuntu 12.04 LTS using boot from CD, when reboot there is no boot option to choose the OS. i directly log in to my Windows 7. before this im having an issue with the 'nomodeset' if not mistaken. after tick [x] on the nomodeset, i can install my Ubuntu, and stuck again at choosing the partition. so i had done 2 partitions for ubuntu, 1 partition for ubuntu ( ext3, mount /) and the other 1 for swap. then i can proceed until finished the installation. and after the system want to reboot. it take some times and just stuck at the screen doing nothing. not rebooting at all. i force to shutdown then restart again then directly go into windows 7 without boot option. in win7 the partitions for ubuntu is gone. i had tried the boot-repair thing and still doesn't help. it just show up the _ (terminal thing i guess). i typed boot repair and still the same. im using acer aspire 4736z. please anybody help me with this issue.

  I am facing a problem. After installing Ubuntu 12.04 LTS using Live CD, at the reboot there is no boot option to choose the OS. I directly get logged into my Windows 7. Before that i was having an issue with the 'nomodeset' if not mistaken .After ticking [x] on the nomodeset, i can install my Ubuntu, but got stucked again at choosing the partition option. So i did 2 partitions for Ubuntu, 1 partition as ext3 for / and the other 1 for swap. Which enabled to proceed until the finished installation dialogue, and after that system wants to reboot .It takes some time and gets stuck at the screen doing nothing, doesn't reboot at all. I did forced shutdown then rebooted again which directly logs me in windows 7 without boot option. In win7 the partitions for Ubuntu is gone. I tried the boot-repair thing and it doesn't help .It just shows up the _ Blank Cursor (terminal thing i guess). I typed boot repair but still the same result. I am using Acer Aspire 4736z. Please somebody help me with this issue.
