  • Disk Utility Restore causes "Could not validate resource - Invalid Argument"

    - by Yahoo
    I have a problem with Disk Utility on Mac OS X 10.6. I have an image of Windows that I would like to use as a bootable volume on a pen drive or external hard drive. The thing is: When I try to restore the volume from the image I get an error: "Restore Failure: Could not validate resource - Invalid Argument" I read some information about that error on the Internet. I converted the image into .iso (Mac OS Extended/ISO (Joliet) Hybrid Image) format and then got this error: "Restore Failure: Could not find any scan information. The source image needs to be imagescanned before it can be restored." When I try to scan the image for Restore, I get the first message. I really read a lot of information about this topic on the Internet, but I haven't found the solution. I tried both ISO and DMG formats; I don't know which is best.

  • System in low graphics, deleted linux, grub rescue, can't access windows

    - by First timer
    So I'm pretty new to Ubuntu but I managed to install it with no big problems on both my desktop and netbook. When I installed it on my brother's netbook everything went horribly wrong and now I fear the system is close to beyond repair. The problem was first that it said it did not have any space left (seemed ridiculous since it had a lot). Then Ubuntu began booting into a "System is running in low graphics mode error" which I then tried to fix, using all the tips I could find in here but nothing helped. I think the graphics error and lack of space might have been related but I can't be sure. Finally I gave up repairing Ubuntu and went for a reinstall. Shouldn't have done that! I read that I should simply open Ubuntu through a live usb and choose GParted to delete the Linux partitions so I did and rebooted accordingly. Next, I was to install Ubuntu but now I am only given the option to wipe the whole disk for Ubuntu, not install along with windows 7. If I access GParted I can still see the ntfs partitions that hold windows 7 (there are 2: one labeled RECOVERY and another labeled OS and boot) so why can't I access them? Btw. the OS and boot has a little red mark with a warning that 1 cluster is referenced to multiple times, don't know what that means. If I boot without the live usb I am sent directly into a grub rescue "black screen of the computer will follow no orders". Please, I know that the easiest might be to simply wipe the whole thing clean but there are important files and programs on windows 7. Is there a way to just access windows? It is a dell inspiron 1018 mini netbook, so I have no cd input and no windows 7 installation cd.

  • Windows7 issue in mutli- tasking and memory

    - by Nitesh
    I seeming some problem in my windows OS recently, let me first say my system configuration. processor - Intel(R) Core(TM)2 Quad CPU Q8400 @ 2.66 GHz Installed memory (RAM) - 4.00 GB (3.00 GB usable) System type - 32 bit operating system I am using two OS in this system, first one is Windows7 and the other is centOS. Well, I am using this from a long time there was no problem , and all of a sudden since from couple weeks I am facing problems in my Windows7 OS. In windows7 i was nearing using multiple jobs almost every time i log in, there was no problem but now i don't no what happen I am not able to do multiple jobs at same time. For example- 1 I am now not able to listen to music in windows media player and view photo's. All of a sudden the system stops working and does not respond and then respond after 5mins and the music get played where it got stopped after 5 mins. 2 When i start browersing internet it hangs all of sudden and doesn't respond for 2 or 3 mins and gets loading. I mean it just happens for every operation i do in the system. Even now typing was also difficult, it gets hanged very frequently even though i am doing single task. I have never come across this kind of problem before. So the first thing i did was to see the useage of the processor and the memory. Well, i thick the useage of the processor was fine, for single task the useage was some where around 3 to 5%. Well, it was something weird i found in the memory, in spite of no task that i was running it was using somewhere around 34 to 41% of memory. So i opened the task manager and click on resource monitor in performance tab. And in the memory section of the monitoring tool i found the usage of my RAM, it was something like this. Hardware reserved - 1029 MB In Use - 1430 MB Modified - 49 MB Standby - 1566 MB free - 22 MB And i could also see Available 1588 MB Cached 1615 MB Total 3067 MB Installed 4096 MB well, this if all i could find out and i have no idea why my computer is acting so weird all of a sudden and the performance problem is growing day by day and i also don't know if there is problem in Bios, i have let it for default settings from long time. please help me and Thank you in advance for reading this and helping me.

  • Seizing The Moment With Mobility

    - by Scott Ewart
    Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt.

  • Cannot see user desktop when I log in

    - by Jesi
    I am very new to Ubuntu. I recently got a new laptop running Windows 7. I am using Virtual Box and just installed the Ubuntu 12.10 ISO as a new Virtual Machine within Virtual Box. Everything seemed to install just fine and I even added the Guest Additions under Devices. The problem is that I cannot see the menus and my login information. The virtual machine says it is running; however, I do not have the Applications, Places, System, etc. tray to select from. Is there something I am supposed to do after logging in to get this? I entered my password and everything seemed fine, I just don't have those drop-down menus available... Thank You! Jesi

  • 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)"

  • Ubunto 12.10 Boots to purple screen

    - by Ric
    I know this question has been tackled in a couple different threads but I've tried what I could from those and have not resolved the issue. I have just a basic understanding of this system so feel free to talk down to me or explain this like you would to a 5 year old. Let's start from the beginning. My son has a computer built by an IT friend of mine (we moved so he can't help any more). It had Windows XP running on it and it just stopped working correctly. This same friend had built a laptop for me with Ubuntu which I liked so I thought I'd put a new OS on my sons computer and it may work better. I downloaded Ubuntu 12.10 onto a USB drive and loaded it onto his computer. I followed all the prompts, it installed, I restarted the computer, it gives me the option of which OS to pick. I pick Ubuntu and it seemingly loads. The desktop comes up with just the basic pinkish Ubuntu background but that is it. There are no icons. I can't right click anywhere to create a file. Left clicking the mouse does not create a square when moved. Alt + F2 doesn't do anything. I can open a terminal but any of the commands I have seen in previous threads do not correct any issues. What else can I do, or what resources are available to fix this problem? I don't know if there are additional files on the USB drive that I need to access or what. Also, one of the problems we were having with my sons computer is that windows would only load to a blank screen. It runs accordingly in safemode and my install of Ubuntu was through safemode of Windows XP.

  • Terminal Server 2003 Performance Troubleshooting

    - by MikeM
    Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

  • Free NTFS partition recovery

    - by Andrei Tanasescu
    I have a 1Tb disk which was partitioned into a ~700gb ntfs disk and a 300gb HFS+ (mac os X). I've accidentally allowed mac os x to wipe the hard-disk and create a single HFS+ partition over the hard-drive. I want to recover my NTFS partition. TestDisk fails to find the NTFS partition, but the DiskInternals solution does find my files. Are there any free alternatives to DIskInternals Partition recovery solution? THe tool should simply go block by block and attempt to reconstruct the files.

  • Same SCSI drive appears multiple times on the controller list

    - by ohad
    Hi, I have an Adaptec AHA-2940UW SCSI adapter, to which I connected a single Atlas 10K III drive (and nothing more). When my computer loads up, the pre-OS Adaptec screen shows (I believe this is called the POST screen), where I can see the Atlas drive listed many times (i.e. with ID0, ID1, ... ID5, ID7, ID8,...,ID15 [ID6 is the adapter itself]) Using the same HD on an Adaptec AHA-2940UB the disk only shows once Since my OS hasn't been installed yet, I'm not sure if this is a problem (I would guess it is), and if so - how to solve it. Termination and multiple LUNs come mind, but the cable provides termination and I don't see why a hard drive would request multiple LUNs, especially considering it is not jumpered at all, and multuple LUN support is disabled in the Adaptec controller BIOS (via the SCSISelect utility) Thank you

  • Can't access Terminal anymore, only shows a cursor

    - by user138304
    I run OS X. Following these directions (Installing MySQL on Mac OS X) I added a file to /usr and the contents were PATH=/usr/local/mysql/bin:$PATH Actually I was trying to get the mysql command to work now I cannot access terminal. All I get is a cursor but no command line. I also cannot find the file I created in the Finder. I used command shift G to find the folder /usr and the file is not there. Edit: I Solved the problem by restarting my computer. I am really not sure what the problem was. I got the idea because Could not open a new pseudo-tty. appeared in my terminal after following slhck directions to remove my .profile file. I then searched google and found this; http://blogs.oreilly.com/digitalmedia/2008/03/fixing-terminal-tty-errors.html. Thanks

  • Unable to boot from LiveCD/USB and even Super Grub Disk!

    - by Reuben L.
    Hi all, I'm in a fix. Basically this morning, I decided to format my Win7 as it was getting really slow and I did so with no problems. I also have a Linux Mint OS on dual boot. Since I was springcleaning my windows partition, I decided it was a good idea to do the same to my linux partition. I downloaded the latest version of Linux Mint (Julia) and burned the LiveCD. Now here is where the problem lies, when I restarted Windows and chose to boot from the LiveCD, it didn't work. No joke. There was just a little underscore blinking for a long time before it went back to GRUB which prompted me to select an OS to boot. However, when I went into my old Linux Mint OS and restarted the machine, the LiveCD worked... to a certain extent. It would load and look as though it was ready to install Linux Mint 10 but the moment it got to the option screen, the whole screen turned into a checkered and jumbled mess. At this point I thought it was the LiveCD or the .iso file. I had an Ubuntu LiveUSB for recovery purposes and I tried that. The exact same thing happened. Can't boot the LiveUSB if I restarted from Windows, but works when I reboot from Linux. BUT still the same checkered screen that doesnt respond. Did a bit of googling and reckoned it might be something wrong with my GRUB. Did some updating and didnt make a difference. Then I tried the Super Grub Disk and STUPIDLY uninstalled GRUB. (Note that booting to SGD had the exact same problem - can't be done if I rebooted from Windows). Now I can't access my Linux Mint 9 cos the the bootup screen (mbr) only has Windows 7 as an option. Remember me mentioning that I can't boot from any CD/USB/recovery CD when I reboot from Windows? And now that I can't access Linux, there's no way for me to do any form of recovery! I've tried using the command prompt utility at startup recovery but to no avail. Anyone can help me with this?

  • Articles of x386 and later CPU based systems

    - by user32569
    Hi there. I know this is hard question, and possibly not to be answered here, but if there is some article, or more you know about, please post a link. About books, its sad but many great computer books cannot be bought in my country. So, you can find many articles online, which says how memory was mapped back in pre x386 CPU. How there was explicit holes ready for MMIO BIOS, Video BIOS, etc. How there was A20 line for allowing higher memory access etc. Problem is, time changed. Today BIOSes are many times larger, and pure x86 16bit mode is used for booting and ROM flashing only. OS ignore BIOS as they access everything using drivers. And I just want to know, how it works today. I know not so specific question, but I read OS dev wiki, many articles, but all refering to days before massive usage of pure 32bit CPUs.

  • Motherboard RAM question.

    - by winterwindz
    Firstly I'm new at this. Not a very computer-ish person. So I very much apologize if this is not the right place, but here it goes.. My Motherboard is an Asus P5LD2-SE. I'm running in Win 7 Ultimate 32-bit(x86) OS, 1GB RAM (2x512 MB). I'm planning to upgrade my OS to 64-bit and because I know my Motherboard is a dual-channel, I bought a dual-channel 2 GB RAM (2 pcs). My question is; am I still able use my old RAM ones, since it is 4 slots..? Which in the end will show 5GB. Is it possible? Thank you for your time. =)

  • Invoke host's workspace switcher from inside VM

    - by Paul
    When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

  • Open file in local text editor from within an SSH connection

    - by Sam
    I'm not a vim guy. I'd like to be able to open log files in Sublime Text when in an SSH connection from within Terminal. Is there a way I could do this? I'm thinking there must be a command or something that could copy the file over to a temporary directory in OS X and then open it in Sublime Text, and when I save it, it'll copy back to the original location through SSH; similar to how FileZilla does it. I'm on Mac OS X MT. The server I SSH into is running Ubuntu. I'm using Terminal.

  • Splitting Pygame functionality between classes or modules?

    - by sec_goat
    I am attempting to make my pygame application more modular so that different functionalities are split up into different classes and modules. I am having some trouble getting pygame to allow me to draw or load images in secondary classes when the display has been set and pygame.init() has been done in my main class. I have typically used C# and XNA to accomplish this sort of behavior, but this time I need to use python. How do I init pygame in class1, then create an instance of class2 which loads and converts() images. I have tried pygame.init() in class 2 but then it tells me no display mode has been set, when it has been set in class1. I am under the impression i do not wnat to create multiple pygame.displays as that gets problematic I am probably missing something pythonic and simple but I am not sure what. How do I create a Display class, init python and then have other modules do my work like loading images, fonts etc.? here is the simplest version of what I am doing: class1: def __init__(self): self.screen = pygame.display.set_mode((600,400)) self.imageLoader = class2() class2: def __init__(self): self.images = ['list of images'] def load_images(): self.images = os.listdir('./images/') #get all images in the images directory for img in self.images: #read all images in the directory and load them into pygame new_img = pygame.image.load(os.path.join('images', img)).convert() scale_img = pygame.transform.scale(new_img, (pygame.display.Info().current_w, pygame.display.Info().current_h)) self.images.append(scale_img) if __name__ == "__main__": c1 = class1() c1.imageLoader.load_images() Of course when it tries to load an convert the images it tells me pygame has not been initialized, so i throw in a pygame.init() in class2 ( i have heard it is safe to init multiple times) and then the error goes to pygame.error: No video mode has been set

  • Accessing localhost:8080 through local network

    - by Theron Luhn
    I'm developing a Python WSGI website. I'm running a Paste development server on my Mac (OS X 10.7) on port 8080. I want to test the website on some other devices and OSs I have connected to the local network (Windows 7 VM, iPad, iPhone, etc.), but am having trouble. I turned on Web Sharing, and am able to access that (port 80) without a problem on all my devices. Port 8080 still doesn't work. An excerpt from my Paste configuration: [server:main] use = egg:waitress#main host = 127.0.0.1 port = 8080 The OS X firewall (Settings - Security - Firewall) is off. I have no other firewall software installed. My network is through a Linksys WRT160N router. I haven't done much with the settings, so most of them are at their defaults. I've been Googling all morning, but can't find a solution.

  • Using my System as the server- need advice

    - by Ashwin
    We are deploying my web application in my system in jboss. And I am planning to use my system as the server as well. There are no html pages or jsp pages deployed. The client requests for resources and the server provides the resources in the form of objects. We are also using databases(Postgresql-15 tables) as the database server(this will also reside in my machine). My system configuration is Windows Vista, 2.3 GHZ, 4GB Ram, 32 bit. There can be many requests coming in at the same time. So is this configuration enough? Should we go with a different Operating System like Windows Server? I have never used Windows Server OS. How will it be different from other windows operating systems? Or if you feel please some other OS will be good in this situation, please suggest.

  • Can I remotely monitor printf results of a C program?

    - by Mota
    I have a long running C program in which I've started from the Terminal.app using: gdb program_name gdb run I'm using many printf statements to monitor the progress of the program. Unfortunately, the screen of the computer has been frozen since yesterday, but the process is still running. My question is, can I watch the progress of the program (i.e. the results of the printf statements) remotely? I'm not that familiar with the terminal, but I know how to ssh and do some simple terminal tasks. The OS of the machine with the frozen screen is Mac OS 10.6.
