  • 'Invalid or corrupt kernel image' error while booting from USB stick

    - by steve
    I got the Ubuntu 11.10 32-bit edition and i used Unetbootin to write the ISO to a usb stick.After that i tried to boot from the stick,having changed the BIOS boot settings,and when the first interface shows up with the choices of istallation,whatever choice i select i got the message"invalid or corrupt kernel image".I use a netbook with windows 7 on it.I tried different usb sticks but same again.I also tried Universal USB installer instead of Unetbootin but same again.Any idea of what happens?I am using ASUS 1000H.The USB doesn't work in one more PC i tried to,but i also tried a second USB to both of the two computers and same again. I downloaded the ISO image once again and follow the same procedure but same again

  • A Console Application or Windows Application in VS 2010 for Sharepoint 2010 : A common Error

    - by Gino Abraham
    I have seen many Sharepoint Newbies cracking their head to create a Console/Windows  application in VS2010 and make it talk to Sharepoint 2010 Server. I had the same problem when i started with Sharepoint in the begining. It is important for you to acknowledge that SharePoint 2010 is based on .NET Framework version 3.5 and not version 4.0. In VS 2010 when you create a Console/Windows application, Make Sure you select .Net Framework 3.5 in the New Project Dialog Window.If you have missed while creating new Project Go to the Application tab of project properties and verify that .NET Framework Version 3.5 is select as the Target Framework. Now that you have selected the correct framework, will it work? Nope if the application is configured as x86 one it will not work. Sharepoint is a 64 Bit application and when you create a windows application to talk to Sharepoint it should also be a 64 Bit one. Go to Configuration Manager, Select x64. If x64 is not available select <New…> and in the New Solution Platform dialog box select x64 as the new platform copying settings from x86 and checking the Create new project platforms check box. This is not applicable if you are making a console application to talk to sharepoint with Client Object Model.

  • How to Create Effective Error Reports

    - by John Paul Cook
    This post demonstrates some generic problem reporting steps that I encourage all users, whether developers or nontechnical end users, to follow. SQL Server has a feature that can help. So does Windows in some cases. More on those in Step 3. Step 1: Is the problem caused by a particular action undertaken on a gui? If so, you should get a screen capture. But if it is caused by executing some T-SQL code in a query window, just copy/paste the offending code as text. There are several ways to get a screen...(read more)

  • Nesting TrueCrypt File Volumes

    - by Maxim Z.
    Is it possible to nest TrueCrypt file volumes? In other words, if I create a TrueCrypt volume as a file and store it inside another TrueCrypt file volume, will it work? (As for what I'm going to store there, I don't know; I'm just experimenting with TrueCrypt.)

  • Missing HDD space - says 65GB used, selecting all folders shows 40GB used

    - by Igor K
    Hi Running Windows Server 2008, 74GB raptor drive and noticed we only had about 500MB left - yikes! So deleted some old backups we don't need, but can't track down where about 25GB seems to be taken up. If I go to C: and select all folders and go to properties, this comes to around 40GB but in My Computer I can see 65GB is used. How can I find out whats eating the space? Just IIS + MSSQL Express + Smartermail on the server EDIT Checked to show hidden folders plus protected operating system files - 41.8GB usage, so 24.6GB is missing somewhere. Theres no system restore even installed on the server

  • How to see whats taking up space on your hard drive

    - by sam
    Im thinking of switching to one of the macbook pro retinas with a 256gb ssd, im making the move from a 512gb hd, which at the moment is split into a 60bg windows partition (which i dont think im going to have on my new machine) and a 440gb main partition of the main partition ive got 140gb free. So all in if i disregard the 60gb windows part ive got about 200gb free so im using 300gb, which is still a bit to much, ive had this machine 4/5 yrs so its likely to be clogged with files that i no longer need, is there a tool that i can use to view my current hd and see whats taking up the most room, so i can begin to see where i can cut down ? just for a bit of background my current machine runs osx.

  • getting a 404/403 error for payment gateway

    - by Obay Ouano
    We are setting up an online payment facility using a payment gateway. After the payment gateway finishes processing the credit card details for a payment, the user is redirected to a "403 Forbidden" page. The logs show: [MY_IP_ADDRESS_HERE] - - [SOME_DATE_HERE] "GET /POSTBACK_URL.php?txnid=1338434567&result=failure&reason=The+remote+server+returned+an+error%3a+(404)+Not+Found.&digest=7a115270c56df5945c43ad86e56b2e930a3cfd50 HTTP/1.1" 404 - "PAYMENT_GATEWAY_URL_HERE" "BROWSER_DETAILS_HERE" It means that when the PAYMENT_GATEWAY_URL attempts to open our POSTBACK_URL, it gets a 404 error, is that correct? But why does the page say "403 Forbidden"? Anyway, we tried to copy-paste that same URL into the browser window, and the page is opened successfully, with our programmed error notification message. So, why couldn't it be opened when the payment gateway tried to redirect to it, but we could? Is this some sort of permissions issue? If so, the postback URL's file permissions are already 755. What am I missing?

Does anyone have an ideas (or a tutorial handy) on how I can mount the LiveCD (on a read-only rescue-cd??) and the install the distru without breaking the RAID?

  • How to properly remove disk from PERC 6/i RAID controller ?

    - by Stefano Borini
    I have a Dell T710, coming with PERC 6/i RAID controller. The current raid has 2x500 GB hard drives (with the OS), and 6x1000 GB hard drives (in RAID-6, currently empty). I would like to take one 1000 GB disk physically out to keep as an immediate spare in case of a crash, and configure the remaining 5x1000 GB in a single VD RAID-6. This is all nice and clean and works, until I realized that the display on the machine reports the lack of the 8th disk as an error. It's marked as error, but appears to be a warning, since the machine is fully functional. My question is: what is the best way to keep one disk as a spare out of the array? should I disassemble the disk from the cradle and insert the empty cradle in the array ? Or should I just silence the error in the display in some way (how?). I know that what I am doing sounds pretty strange, but here is academia and having a spare disk available could take weeks. Better to have one ready in my drawer for any emergency.

  • How do you passthrough native SATA drives to a guest on ESXi?

    - by John
    I have ESXi 4.0 running on an Intel DX58S0 Mothboardboard with an Intel Core i7 930 processor. VT-d is also enabled. I have three drives in the system, drive 0 is used for ESXi. Drive 1 and 2 contain data from an older machine and show up under the "Storage Adapters" section in configuration. I would like to allow a guest machine to access the data on these drives (as nativly as possible). I have enabled passthrough of the motherboard's built in SATA controller (Intel/Marvell 88SE6121 ). This controller shows up in my guest OS, but the guest shows no drives aside from the normal virtual drive. I have tried a Linux guest and Windows7. I have also configured the host machine to try IDE/RAID/ACHI modes for the SATA controller. Any ideas how I can configure one of my guests to get at the raw data on these drives?

  • FDE with DiskCryptor V1 (TRIM Support) on Crucial M4 SSD on W7 x64 - Unpartitioned Space?

    - by JamesM
    I have a new Alienware m11 laptop with a brand new Crucial M4 128GB SSD. I have installed the SSD but not used it yet. I am thinking of using FDE with DiskCryptor 1.0.732.111. I will install Win7 Pro x64. I have read about support for TRIM in v1.0.732.111 but also about leaving unpartitioned space. My SSD drive, 'Crucual M4' does not have a manufacturer built-in reserve like other drives. My questions are: Should I leave some free unpartitioned space with v1 of DC and W7x64 even though it will support TRIM or should I not do this? Should I install DC v1 first or after installing Windows 7 (assuming it is brand new, never been used SSD)?

  • help building a PC that can image a dozen hard drives simultaneously

    - by Bigbio2002
    Not sure if this belongs on here or SuperUser, but here goes... I'm trying to figure out how to make a mass hard drive imaging PC out of COTS parts. A dedicated imaging device can do 10 drives at a time, but costs several thousand dollars. So far, I'm thinking to use several 3-port PCI-E Firewire cards, and use some kind of Firewire-to-IDE adapter to connect the drives themselves. The "software" would consist of scripting diskpart, or some other imaging utility. The problem is that I can't seem to find any sort of adapter. I could use standard external hard drive bays, but then I'd have a dozen power cables that I need to plug in. Ugly, messy, and inefficient. I picked Firewire over USB not only for better transfer speeds, but also because FW can deliver power over the bus (and could theoretically power a hard drive). Does anyone have any input on this?

  • Error loading operating system WinXP Pro

    - by Jakesan
    So im getting the error "Error loading operating system" when the computer tries to boot to a fresh install of WinXP Pro. To get to this point, I: Shrunk the only partition with Gparted to 33GB Copied the partition to the end of the 200GB drive Enlarged the first one to fill the space Formatted the first partition to NTFS Set the first partition to boot, tagged the latter to hidden, removed boot flag This was done all under Hiren's BootCD. Now this is where it goes down the drain. I installed XP Pro SP1a from its CD, and chose to quick format the partition. Now after the OS was installed, I can't start XP without using the default menu action from Hiren's BootCD. All I am greeted with is the "error loading operating system" message. I tried to use the XP recovery to fixboot, fixmbr and bootcfg /rebuild (dont remember if the command was like this, anyway the 3 suggested commands). This did nothing. What am I missing here?

    - by spender
    I need to take an image of a drive. I'm working from a bootable CD, so I have the option to decruft before taking the image. The Windows installation on the drive has both hyberfil.sys and pagefile.sys which I would rather not include in the image. If I delete these from the drive, will Windows recreate these files if necessary? EDIT The Windows installation on the drive in question was shut-down cleanly.

  • DOS Batch file to find "new" files by date

    - by Todd McArthur
    My PC has entered an infinite BSOD loop - but I do have access to a safe-mode command prompt. I'm trying to get an idea of "what changed" that might have triggered this. e.g. I might have gotten a virus, or an app update went belly up. I'd like to thus see which files were created/modified in the last few days/week or at least the *.exe, *.dll, *.com, *.bat etc. I thought I was ok with my Batch-fu but I'm stumped on how to write a quick batch file/command that would list the files for me. REM This will find the files, but the results are all muddled REM all EXE files, reverse sort by date, recursively through sub-directories dir *.exe /O-D /S What I'd really like is to find all (executable filetypes) that were created/modified in the last 3-7 days. Can anyone point me in the right direction?

  • FoxPro 2.6 DOS on Windows 7 64-bit

    - by Rolando
    I support a company that has a very old, mission critical, FoxPro for DOS 2.6 (FPD) application. For variuos reasons the company didn't adapt/migrate their app, which, ironically, has been running even better under Windows XP (and 32-bit Win7) because the OS allowed new features like more reliable networking, distributed printing, email integration. Unfortunately for this company, most new machines now come with a 64-bit version of Windows 7, which is incompatible with their FPD app. I know this time the writing is on the wall: the only long-term solution is to migrate their app. But I wonder if anyone can suggest a temporary alternative path, which doesn't involve either: downgrade 64-bit Windows to 32-bit, or run the app on a virtualized 32-bit XP

The layout of the disks are as follows: Disk /dev/sda: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0003f3b6 Device Boot Start End Blocks Id System /dev/sda1 * 63 481949 240943+ 83 Linux /dev/sda2 481950 2910640634 1455079342+ fd Linux raid autodetect /dev/sda3 2910640635 2930272064 9815715 82 Linux swap / Solaris Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00069785 Device Boot Start End Blocks Id System /dev/sdb1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdb2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdc: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdc2 2910158685 2930272064 10056690 82 Linux swap / Solaris Disk /dev/sdd: 1500.3 GB, 1500301910016 bytes 255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000f14de Device Boot Start End Blocks Id System /dev/sdd1 63 2910158684 1455079311 fd Linux raid autodetect /dev/sdd2 2910158685 2930272064 10056690 82 Linux swap / Solaris The first disk (/dev/sda) contains the /boot partition on /dev/sda1. I use grub2 to boot the system off this partition. On top of this raid10 I installed two volume groups, one for /, one for /home. This system worked well, I even exchanged two disks during the last two years. It always worked. But not this time. For the first time, /dev/sda broke. I do not know if this is an issue – I know I would have struggled anyways to overcome the problem with /boot installed on that disk and grub2 installed on the mbr of /dev/sda. Anyways, I did what I always did: start knoppix fire up the raid sudo mdadm --examine -scan which returns ARRAY /dev/md127 UUID=0dbf4558:1a943464:132783e8:19cdff95 start it up sudo mdadm --assemble /dev/md127 fail the failing disk (smart event) sudo mdadm /dev/md127 --fail /dev/sda2 remove the failing disk sudo mdadm /dev/md127 --remove /dev/sda2 stop the raid sudo mdadm -S /dev/md127 take out the disk replace it with a new one create the same partitions as on the failling one add it to the raid sudo mdadm --assemble /dev/md127 sudo mdadm /dev/md127 --add /dev/sda2 wait 4 hours All looks fine: cat /proc/mdstat returns: Personalities : [raid10] md127 : active raid10 sda2[0] sdd1[3] sdc1[2] sdb1[1] 2910158464 blocks 64K chunks 2 near-copies [4/4] [UUUU] unused devices: <none> and sudo mdadm --detail /dev/md127 returns /dev/md127: Version : 0.90 Creation Time : Wed Jun 10 13:08:46 2009 Raid Level : raid10 Array Size : 2910158464 (2775.34 GiB 2980.00 GB) Used Dev Size : 1455079232 (1387.67 GiB 1490.00 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 127 Persistence : Superblock is persistent Update Time : Thu Mar 21 16:27:40 2013 State : clean Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 64K UUID : 0dbf4558:1a943464:132783e8:19cdff95 (local to host Microknoppix) Events : 0.4824680 Number Major Minor RaidDevice State 0 8 2 0 active sync /dev/sda2 1 8 17 1 active sync /dev/sdb1 2 8 33 2 active sync /dev/sdc1 3 8 49 3 active sync /dev/sdd1 However, there is no trace of the volume groups. Rebooting into knoppix does not help Restarting the old system (I actually replugged and re-added the failing disk for that – the system begins to start, but then fails to see the / partition – no wonder if the volume group is gone) does not help. sudo vgscan, sudo vgdisplay, sudo lvs, sudo lvdisplay, sudo vgscan –mknodes all returned No volume groups found. I am completely at a loss. Can anyone tell me if and how I can recover my data? Thanks in advance!

  • "unresolvable problem" error when upgrading from 12.04 to 14.04

    - by flyingfisch
    So I have solved this issue, but now I have another problem: An unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. I am not upgrading to a pre-release version of Ubuntu and I am not running a pre-release either. I have unchecked all my 3rd-party packages using Ubuntu Software Manager, EditSoftware Sources... What else might be wrong? UPDATE After doing sudo update-manager -d and sudo apt-get update;sudo apt-get dist-upgrade as per JimB's post, and then running sudo do-release-upgrade, here what I get: Err http://extras.ubuntu.com trusty/main Translation-en Err http://extras.ubuntu.com trusty/main Translation-en_US Err http://extras.ubuntu.com trusty/main Translation-en Ign http://extras.ubuntu.com trusty/main Translation-en_US Ign http://extras.ubuntu.com trusty/main Translation-en Fetched 0 B in 0s (0 B/s) Checking package manager Reading package lists...

  • webmaster tools 500 crawl error for asp faceted navigation that does not exist

    - by user19007
    i am getting 2,500 type 500 url errors in google webmaster tools. These pages are faceted navigation results that can not be reached by a site visitor. These pages do not exist. We are using faceted navigation with the Volusion platform (asp.net, I think). I have specified url parameters in webmaster tools so that google will not try to index anything faceted. This does not stop the errors from generating. I am concerned about how this might effect seo (bleeding page rank). I can provide additional information if needed. I am not sure how to solve this. I have started down the path of creating 301's, but having some difficulty there as well.

  • What happens to a Windows Dynamic Drive

    - by GruffTech
    In my windows (Windows 7) I have two primary logical volumns, One is on a SSD harddrive for my operating system and installed software, and my other is a Dynamic volume for my stored media. (I do alot of work with HD footage) I have all my media on the original DV tapes for backup purposes, just having them all available on my harddrive at all times is a major convience for me, well worth the few hundred dollar investment those 2TB drives were. Anyway, Long story short is my windows install has become problematic and I want to reformat windows. Does this, or will this effect my dynamic drive in any way? I've got almost 3 TB of video on there and i really dont want to re-import all my DV tapes.
