• Grub loading. The symbol ' ' not found. Aborted. Press any key...

  - by John

  Hi there, I have a dual boot system on dell xps 9000 with windows 7 and ubuntu. But after I performed system backup on it as requested by windows 7 I am no longer able to boot into the computer, instead at the beginning after bios I get the following message: Grub loading. The symbol ' ' not found. Aborted. Press any key... I tried to change bios booting config to starting with harddrive and it still returned the same message. Using windows boot disk only asks me to do another system backup or threatens to delete my harddrive completely. The only solution I have so far is to reinstall ubuntu, but that leaves 2 additional copies of ubuntu on my computer. Is there a simpler way to fix the situation so I can actually boot into windows? Thanks so much.

• Prevent EC2 machine from halt, poweroff, shutdown

  - by Adam Matan

  Hi, EC2 Ubuntu servers erase all disk contents when being shut down. Following an unfortunate accident, I have decided to prevent the command-live halt, poweroff and shutdown. What's the best way to do it? I thought about renaming these commands (at /sbin) to something like HALT_RENAMED___ERASES_ALL_DISK_CONTENTS. Are there any files, other than the three listed above, that needs to be handled? I've noticed that halt and poweroff are merely links to reboot. Should reboot be renamed, too? Adam

• forced reformat without login / and bootcamp

  - by debug

  ok.. im pretty good with stuff like this, but I have a question. I have mac mini with 10.5.(x) on one partition, and bootcamp (windows) on the other. My boss wants me to reformat the whole mac (10.6 (x)), which is usually easy. He does not remember his password to login, which means I cannot log in and allocate the bootcamp back to one partition using Disk Utility, then reformat the whole drive. When I insert the Snow leopard CD, I can only wipe out one partition, my question is: Is there a way to force a wipe out of both drives in the boot sequence? Any help to wipe out this whole drive and do a clean install would be helpful.. Thanks superusers!

• Cloning a USB flash drive to another larger one, is it safe to do so?

  - by Rob Kam

  I used Acronis True Image Home 2010 to clone a Dane-Elec zLight 8Gb pen drive/USB flash drive to a PNY Attaché 16Gb USB flash drive. Now WinXP shows the drive in device manager as USB DISK 2.0 USB DEVICE but doesn't have it in My Computer/doesn't assign it a drive letter. What is it that has messed up the PNY Attaché and is there some way to repair it so that it can be used as a regular USB flash drive again? Is there a safe way to clone a USB flash drive to another larger one? How safe is it to backup and restore a USB flash drive to/from a drive-image?

• Netboot Intel Macs without BSDP

  - by notpeter

  I have a netboot setup with DeployStudio that works great in my lab, but doesn't work on our main network. After some digging, I believe it's because our network admins are filtering BSDP (Boot Service Discovery Protocol) on our subnet at the switch level. Is it possible to hard code which server my clients (early 2007 iMac Core2Duos) should boot from without relying on BSDP? Perhaps relevant details: I do not have control over switch configs or DHCP settings. Client and server are running 10.6 Snow Leopard. The clients see the netboot server advertising itself in the 'Startup Disk' system preferences pane, but when I go to netboot it just leaves me with a flashing globe.

• Scheduled service/script/batch file to move files on condition of other files with similar filenames in same directory on windows

  - by ilasno

  On Windows Server (Data Center? 2008?), i'm trying to set up a scheduled task that will: Within a particular directory For every file in it If there exists (in the same directory) 2 files with similar names (actually the same name with extra extensions tagged on, ie. 'file1.mov' would need both 'file1.mov.flv' AND 'file1.mov.mpg' to exist), then move the file to another directory on a different disk. Following is what i have so far for a batch file, but i'm struggling. I'm also open to another technique/mechanism. @setlocal enableextensions enabledelayedexpansion @echo off SET MoveToDirectory=M:\_SourceVideosFromProduction ECHO MoveToDirectory=%MoveToDirectory% pause for /r %%i in (*) do ( REM ECHO %%i REM ECHO %%~nxi REM ECHO %%~ni REM ECHO filename=%filename% REM SET CurrentFilename=%%~ni REM ECHO CurrentFilename=%CurrentFilename% IF NOT %%~ni==__MoveSourceFiles ( IF NOT x%%%~ni:\.=%==x%%%~ni% DO ( REM SET HasDot=0 REM FOR /F %%g IN %filename% do ( REM IF %%g==. ( ECHO %filename% REM ) ) ) ) pause

• iSCSI: LUNs per target?

  - by badnews

  My question relates specifically to ZFS/COMSTAR but I assume is generally applicable to any iSCSI system: Should one prefer to create a target for every LUN that you want to expose? Or is it good practise to have a single target with multiple LUNs? Does either approach have a performance impact? And is there some crossover point where the other approach makes sense? The use case is for VM disks, where each disk (zvol) is a LUN. So far we have created a a separate target for each VM; but a single target that contains all the LUNs would probably greatly simplify management... but we may need hundreds of LUNs per a single target. (And then possibly tens of initiator connections to that target)

• Physically moving a hard drive from older iMac (c2d) to new iMac (i7) ?

  - by Inshim

  Instead of my usual habit of using superduper to mirror my drive to a new computer, I just physically moved the hard drive from an older iMac to a new one. But... it now doesn't boot, getting stuck at the apple logo screen. Since the hard drive that came with the new iMac works well, and my old drive works well when I return it to the older iMac, I conclude that there is some problem at the system/kernel level due to the different hardware. In the past I did similar things (e.g. starting a C2D machine from a Core Duo in target disk mode), so perhaps the change in architecture to the i5/i7 is too problematic? The main point: do you know of any way to get the system to rebuild for itself the proper versions of the system components when booting? Are there certain directories that I can safely delete to make that happen? Thanks

• Windows 7 Professional N needs to be just Windows 7 Professional.

  - by Jess

  I have a laptop at work that originally had Windows 7 Home Premium on it. We have a tech that comes in a few times a week to do some of our support work, and we asked him to upgrade the laptop to Windows 7 Professional. Before he left he told us the upgrade didn't work and that we'd have to order a disk. Upon checking the computer it seemed he had upgraded to Windows Professional 7 N. It had not previously been Home Premium N, so I'm not exactly sure how he managed to upgrade it to an N edition. I do not understand why he didn't run the Any Time Upgrade, but that is now irrelevant. How can I change Professional N to regular Professional? I would like to avoid having to restore it back to Home if possible.

• ZFS: RAIDZ versus stripe with ditto blocks

  - by RandomInsano

  I'm going to build a ZFS file server from FreeBSD. I learned recently that I can't expand a RAIDZ udev once it's part of the pool. That's a problem since I'm a home user and will probably add one disk a year tops. But what if I set copies=3 against my entire pool and just throw individual drives into the pool separated? I've read somewheres that the copies will try and distribute across drives if possible. Is there a guarantee there? I really just want protection from bit rot and drive failure on the cheap. Speed's not an issue since it'll go over a 1Gb network and at MOST stream 720p podcasts. Would my data be guaranteed safe from a single drive failure? Are there things I'm not considering? Any and all input is appreciated.

• How to mount remote samba share from local host with multiple groups?

  - by Dragos

  I am using mount.cifs to mount a remote samba share (both client and server are Ubuntu server 8.04) like this: mount.cifs //sambaserver/samba /mountpath -o credentials=/path/.credentials,uid=someuser,gid=1000 $ cat .credentials username=user password=password I mounted a user from local system with username and password with mount.cifs but the problem is that the user is part of multiple groups on the remote system and with mount.cifs I can only specify one gid. Is there a way to specify all the gids that the remote user has? Is there a way to: Mount the remote samba with multiple groups on the local system? Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs. Other solutions would be: nautilus sftp:// which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal. And the last solution would be NFS but that means that I have to synchronize the uids and gids on the local system with the ones from the server.

• OEM Office 2010 without media - how to reinstall?

  - by Bryan

  I have recently purchased a new office desktop PC from Dell with OEM version of Windows 7 Pro and Office 2010 Pro. One of the reasons I always use Dell is that they always supply installation media CDs or DVDs, unlike some other companies that just give you ISO images on the hard disk that you have to burn yourself. This is the first PC I have purchased with Office 2010 Pro (OEM), and I was disappointed to see that Dell don't ship out any installation media for office 2010, they just supply a piece of card with the office pro product key printed on it. If the HDD fails completely and I have to perform a clean installation, how can I re-install office? Can I download the trial version of Office 2010 and install that, then offer it my product key? Bearing in mind that the product key is an OEM product, not a retail product, would this work?

• Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not am not a "handsome prince"!

  - by Jim Dobbs

  Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

• Calculating IOPS for a single HDD - what am I doing wrong?

  - by red888

  So I know there is no standardized way of calculating IOPS for a HDD, but from everything I have read it appears one of the most accurate formulas is the following: IOP/ms = + {rotational latency} + ({block size} / {data transfer rate}) Which is IOs per millisecond or what the book I've been reading calls "Disk Service Time". Also rotational latency is calculated as half of one rotation in milliseconds. This was taken from the EMC book "Information Storage and Management" -arguably a pretty reliable source right\wrong? Putting this formula into practice consider this Seagate data sheet. I am going to calculate IOPS for the ST3000DM001 model for a block size of 4kb: Seek Average (Write) = 9.5 -I'll measuring IOPS for writes Spindle speed = 7200rpm Average Data Rate = 156MB/s So my variables are: Seek Time = 9.5ms Rotational latency = (.5 / (7200rpm / 60)) = 0.004s = 4ms Data Rate = 156MB/s = (0.156MB/ms / 0.004MB) = 39 9.5ms + 4ms + 39 = IO/ms 52.5 1 / (52.5 * 0.001) = 19 IOPS 19 IOPS for this drive clearly is not right so what am I doing wrong?

• Make a file non-deletable in USB

  - by MegaNairda

  Somebody used my USB drive and upon returning it to me, I found a autorun.inf that is undeletable. I tried changing it's file attribute which is only H (not even set as a system file) but it keeps on saying Access Denied. The USB is set on FAT32, upon asking my friend, he told me that he uses Panda USB Vaccine http://research.pandasecurity.com/Panda-USB-and-AutoRun-Vaccine/ How do they do this? Im trying to use some Disk Sector editor but have no idea which hex file they change to make this kind of file and make it deletable again. Formatting the drive removes it, but I'm curious as to how to be able to set those kind of file attribute.

• diagnose "corrupt file" problems

  - by Matthew

  My computer has been crashing the last couple weeks pretty regularly (at least once a day). A lot of times things I do will display a little notification in the bottom right saying something about a corrupt file. (I'm on Windows XP Pro Service Pack 3). When the computer does crash I get the "blue screen of death" usually. Some of the notifications also advise running the chkdsk utility. I cannot get it to successfully run. Using the command prompt (or even the "tools" menu after right clicking the drive and choosing properties), it will not run the utility (it says "do you want to schedule it to run next boot time" or whatever, which I confirm). The problem is that most of the time after restarting, it doesn't run at all. The few times it does run, it has an error (I can't remember the error right now, it at least says it's ntfs and such) and says disk checking will end. How can I get it to successfully run?

• Where exactly does a portable app is running when the usb stick is pulled out without closing that app?

  - by Selin Peck

  Where exactly does a portable app is running when the usb stick is pulled out without closing that app? Is it in memory? Is it written the on hard disk as temporary files (where exactly is it, appdata or where)? Does that mean the next user of the pc could gain access just clicking that from the system tray and saving to other folders? How about when the system crash and that portable app is not closed the normal way? On the next open, will it stay somewhere on temporary folders?

• How to netboot ubuntu running iniside VirtualBox on Mac Air

  - by murungu

  Having configured a virtual machine for Ubuntu on VirtualBox on my mac air I need to install Ubuntu OS itself. I have selected the hardrive as the primary boot device and the network as the secondary boot device, so I am not prompted to install an Ubuntu disk at boot time. It attempts to netboot but is unable to locate Ubuntu and cannot find anywhere in the configuration where I can explicitly specify where to find and Ubuntu image, so assume it reverts to some default location and fails. Has anybody out there ever successfully installed ubuntu on virtual box on their Mac Air? What steos did you take to get it right?

• Recovering text files in terminal using grep on Mac OS X Snow Leopard

  - by littlejim84

  I foolishly removed some source code from my Mac OS X Snow Leopard machine with rm -rf when doing something with buildout. I want to try and recover these files again. I haven't touched the system since to try and seek an answer. I found this article and it seems like the grep method is the way to go, but when running it on my machine I'm getting 'Resource busy' when trying to run it on the disk. I'm using this command: sudo grep -a -B1000 -A1000 'video_output' /dev/disk0s2 > file.txt Where 'dev/disk0s2' is what came up when I ran df. I get this when running: grep: /dev/disk0s2: Resource busy I'm not an expert with this stuff, I'm trying my best. Please can anyone help me further? I'm on the verge of losing two days of source code work! Thank you

• Shared block device file system (cluster file system without networking)

  - by fungs

  Is there any file system that can be mounted multiple times and supports concurrent file access for Linux? Basically I want something like a cluster file system but without the need to have a running network for a distributed lock manager. That can be very handy in connection with virtual machines that can share data with the host or another VM without the need to create a network link. This I want to avoid to keep the network architecture secure (virtual machine in DMZ) but share large files. No need to scale it up, just two machines that mount the same block device. Shouldn't it be possible to have file locking information right on the disk?

• Transfer nearly an entire file system to a fresh install as smoothly as possible

  - by Xander

  I've got a friend who needs his computer working in just a few hours. His files are safe, however, he managed to corrupt his main install of Windows 7. My plan is to go in with a Linux disk, copy his C:\ do a backup drive I've got and then reinstall. Restoring many of his files will be pretty simple (such as documents and such), however, things such as applications won't transfer as easily. Is there any easy way to transfer applications such as MS Office (which he needs in the morning) or other commercial software packages without having to go through the hassle of locating the keys and reinstalling them completely? I don't think just moving them over will work just because of the fact that I'm sure much of that is stored in the registry (validation stuff and such). Anyways, quick responses would be super nice! Also, additional help would be great!

• Restoring Box Sync (box.com) using physical media after OS reinstall

  - by sjrm

  I have my Box Folder on a different drive ( D: ) than my Operating System Drive ( C: ) I follow these instructions to set the local folder on the second drive. https://support.box.com/hc/en-us/articles/200852947-How-Can-I-Change-the-Default-Folder-Location-for-Box-Sync- I had to format and reinstall Windows 7, leaving the other drive (D: ) untouched. now i reinstalled Box Sync, and directed it to the same location where i already have all my files. However, Box Sync renamed the folder to (Box ([email protected]) ) as a bckup, and is downloading everything again. As i have like 30Gb of files, and it takes many hour to download them, i just want to use the files that i already have in my local disk. i tried copying all files again to the new local Box Folder, but files started to get duplicated. Is there any way to avoid downloading everything again each time i reinstall my OS ? Thanks
