  • Is it possible to "stealth" dual boot a machine?

    - by BrianH
    I have a loaner laptop that has MS Windows with locked down permissions. It works okay for what I need to do, but I started wondering if there was a way to install a separate Windows OS on a separate hard drive to do what I want to do on it. Virtual I wish I could use VirtualBox or VMWare, but that is not an option (I even tried VBox portable). External Drive My next trial was see if it was possible to install Windows on an external drive, and then plug that drive in and boot from it whenever I wanted my own OS. After a few Google searches, I see that is not really a possibility. Swap Primary Drive Another option, would be to get a second internal hard drive, take the existing HD out, and install a new Windows OS on the secondary HD. This would mean swapping the internal hard drive each time I want to switch OSs - doable, but not very convenient. Dual Boot The laptop has an expansion slot where a second hard drive can be plugged in quickly. I thought about Dual booting, but I don't want to mess with the MBR on the primary hard drive. When I have to give the laptop back, I don't want a dual-boot screen to popup. Summary Is there a way to have 2 hard-drives on a machine, each with it's own OS, and maybe use BIOS settings to have only 1 hard drive active at a time? That way both hard drives could be physically connected, but only one would actually be active at a time. I basically want a second OS that does not (can not) affect the existing OS in any way, and can be removed at any time without affecting the existing OS. The secondary OS does not need any of the files on the main hard drive - it's basically like having 2 separate computers using the same hard ware... Is this possible, or would it be easier just to go out and buy a different laptop? Thanks in advance! EDIT I just discovered that my BIOS allows me to pick (at startup) which hard drive I want to boot from. I poked around in the BIOS and there is not a place to disable certain devices, like the primary hard drive. My only concern about plugging in a second hard drive and installing Windows to the second hard drive is that it will mess with the primary hard drive, or add a bootloader screen to pick which windows install to use. My thought would be to physically unplug the primary, plug in the secondary and install windows to the secondary. After the install is working properly, I can plug the primary back in and use the BIOS feature to determine which drive to boot to. Is there any way after I have 2 separate installs on 2 separate hard drives that one of the installs could mess with the MBR on the other drive?

  • On dual-boot iMac, after fixing "EFI Boot" issue, will booting Windows cause the same issue again?

    - by Shane
    On my dual-boot iMac, after fixing the well-known "EFI Boot" issue, will booting Windows cause the same issue again? I'm hesitant to try booting Windows until I hear from others. Details: It all started when I had been working in Windows and then re-booted into Mac OSX Snow Leopard. Any attempt to boot into OSX would result in two giveaway symptoms: 1) The MAC HD was re-named "EFI Boot", and 2) a gray progress bar stopped at 10% and the spinning wheel kept spinning - no joy. Many articles on Mac Forums describe the same thing, including the fix, which is to erasing the damaged partition and either: a) re-install the OS from DVD, or b) perform a Time Machine RESTORE (which I did). Is there anything I can do to keep enjoying the benefits of a dual-boot iMac without fear of a repeat problem and associated 2-hour restore from Time Machine?

  • Ubuntu on an XPS 14 Ultrabook with mSATA cache and 500GB HD - how to partition for dual boot?

    - by JDS
    I am getting an XPS 14 ( http://www.dell.com/us/p/xps-14-l421x/pd ) and I want to dual-boot Windows and Ubuntu. This thing has a 500GB standard HD and a 32GB mSATA that can be used as cache. Does anyone know how this thing is partitioned? Is the OS installed on the mSATA drive and data is on the big HD? Is there a BIOS controller or maybe even a Windows driver that makes the mSATA drive and 500GB HD appear contiguous? I get the impression that something makes the mSATA be used invisibly as cache, but I can't find any technical documentation how that works. My primary concern here is wrt dual-booting Ubuntu. I want to know if I need to partition the mSATA separately, or the big HD, or just partition the "magic" contiguous disk space that appears available to the OS.

  • Why are there so few Wireless N Dual Band adapter PCI cards, only USB adapters instead?

    - by daiphoenix
    There has been several Wireless N Dual Band routers/APs out in the market for quite some time now, and there are several Wireless N Dual Band USB adapters out there. But as for PCI/PCI-X card adapters, there seems to be only one (the Linksys WMP600N). Why is that? I find it very strange. Is it because the USB adapters are easier to install, and can be used on multiple computers? But if so, why isn't it the same case with single band (2.4 Ghz) wireless N adapters? Because for these ones there as many PCI card adapters as there are USB adapters. Also, can the USB adapters, despite the lack of external antenna, offer the same level of performance as a card with external antennas?

  • 64 bit Windows 7 + 32 bit windows XP dual boot?

    - by Mick
    I have purchased an i7 based PC pre-installed with 64 bit windows 7 (home premium). Unfortunately some third party 32 bit software that I need to use is not working properly (see stackoverflow.com for details). I am now torn between the plan of installing windows XP 32 bit or making it dual boot. Which option do you think will give me the least problems? And if the answer is dual boot, then can you point me to a good guide for how to do it, preferably a guide specifically for my two OS's created in this order (i.e. 7x64 first). EDIT: the performance of my 32bit programs is critical so am concerned about any kind of 32bit XP "emulation".

  • Enabling "AllowDualLinkModes" in xorg.conf

    - by Gausie
    I'm using a GeForce GT 620 (which is dual-link compatable) and a DVI-I dual-link splitter to try to have a desktop extended onto two monitors. At the moment when I plug in the monitors, only the monitor on the female VGA marked "1" gets a signal, and the other screen gets nothing and only one screen is detected by nvidia-settings. After reading around, I have realised that my graphics card probably comes with dual-link disabled by default, and I can enable it by adding an "AllowDualLinkModes" option to my xorg.conf. This is the current state of my xorg.conf Section "Device" Identifier "Default Device" Option "NoLogo" "True" EndSection Where do I put the line about AllowDualLinkModes? Do I create a new Section? Have I misunderstood? Cheers Gausie

  • Ubuntu 9.10 Karmic, nVidea Quadro NVS 280 PCi, Eizo S1921 Dual Screen (Twin View) Slow Window Draws

    - by Spasm
    I have been following this Tutorial to get dual monitors working on my box http://www.dwasifar.com/?p=862&cpage=1#comment-5727 It works! However, when ever I move a window, the redraw of that window takes 3-8 seconds. Even moving the window takes the same amount of time Is this being done in software rather than the nVidea hardware? The windows themselves do not respond. I have seen a few old threads but no relevant fixes - If anyone could suggest a fix I would very much appreciate it. Thanks in advance

  • What could cause a dual-monitor PC to suddenly stop using one of the screens?

    - by raldi
    I've got a dual-monitor setup using a GeForce 7900GT that was working fine for over a year... then suddenly, only one of the screens works. It's not OS-related, because even on startup, only one screen displays the BIOS checks. In the past, both screens would show it together. I didn't change anything to trigger this The monitor that gets a signal is random -- sometimes the one on the left goes black, sometimes the one on the right. The monitors and their cables are good -- I can switch both or either, and I get a signal just fine. They're plugged in, too. It's not the video card, either -- I have an identical 7900GT in another machine, and swapping the two didn't fix anything. It's not dust on the motherboard -- I pulled everything out, cleaned it off, checked for obvious damage, put it all back together, and no change. My next two steps are going to be to reset the CMOS info and to try swapping out the motherboard. Before I do that, does anyone have any other ideas?

  • On dual boot system, Is it possible to use VirtualBox to boot other installed OS?

    - by Derek Ziemba
    I currently run Windows 7 from a 256GB SSD as my Operating System. Lately, for school, I've been using openSUSE linux inside a VirtualBox PC and I'm really liking it. I'm starting to hate even working in Windows. But I can't just abandon Windows. I've been considering dual booting openSUSE and will likely purchase another SSD for openSUSE. Once I have the dual boot set-up, there is going to be times I need to do something quick in the operating system that I'm not currently in. It would be a pain to have to reboot the computer each time I need to switch the OS for a simple task, especially from Windows since it doesn't let you save it's state. From openSUSE, I want to be able to start a VirtualBox Machine using my Windows Drive. And in Windows, I want to be able to start a VirtualBox Machine of my openSUSE Drive. Would this be possible? The issue I'm worried about is drivers. For instance, the OS will be installed on native hardware and have the native hardware's drivers configured. When I try to boot the OS in a VirtualMachine, I feel like the OS is not going to know what to do, and have to reconfigure itself or just not work.

  • NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

    - by Big Daddy
    Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

  • ATI Radeon HD with Catalyst driver stuck mirroring screens

    - by Mike Axiak
    In 11.10 I replaced my aging Nvidia card with a new Radeon HD 6970 card. The single card has two DVI output ports which I've connected to two monitors. I installed Catalyst version 11.9 and I cannot get multiple monitors set up the way I want. I tried: $ sudo amdcccle and setting the mode to single desktop multiple monitors and whenever I do that Unity crashes and I get back to the login screen. Nothing shows up in the Xorg.*.log files for me to post here. There's only one card so I don't think xinerama would be any help here. Anyone have any ideas?

  • Windows Remote Desktop with multiple monitors

    - by BDW
    I'm looking for a remote desktop product that will allow me to switch on the fly between how many monitors the desktop is using. This would be going from one Windows 7 machine to another, one is running Ultimate, the other Enterprise. I know I can use Windows RDP with multi-monitor support, but it seems that only allows me to use ALL monitors, and if I switch to a windowed view, I get huge scrollbars because I'm going from 3 monitors to 1 window. What I'm looking for is something that will allow me to switch from 1, 2, or 3 monitor displays without restarting the RDP and would end up with a true 1/2/3 display - ie, if I go from 3 monitors to 1, or a window, I don't get scrollbars. Is there any such product?

  • Unity 3d support for multiple X-screens

    - by stewbond
    I've installed Ubuntu 12.04 this weekend and have had problems getting Unity3d to work with my triple monitor set-up. I've installed the latest nVidia drivers for my 2 nVidia video cards and have used NVIDIA X Server Settings to configure everything. If I stick each monitor on a separate X screen, all but the primary X screen will appear white and the cursor will be a black X. I can start a terminal on this screen but cannot drag other windows to it. If I kill the "Nautilus" process, the white background disappears and I see my desktop background, but my cursor is still an X and I still cannot drag windows to it. If I enable TwinView, I can get one screen on two monitors to work properly, but the white screen remains on my third monitor. In addition, I don't like using TwinView because my full-screen applications get stretched. My current solution is to "Enable Xinerama", use all separate X screens and revert to Unity2d. I'd love a solution to this as Ubuntu 12.10 is not planned to support Unity-2d and prefer the aesthetics of 3d anyways. I can provide Xorg.conf for all configurations and any other suggested diagnostic information.

  • Radeon HD 5770 - DisplayPort Problem

    - by Nick Schmit
    I am trying to set up 3 monitors with the Radeon HD 5770 I recieved a few days ago. I have read that I can use 2 DVI ports and an active DisplayPort adapter for a third DVI monitor. I have purchased this adapter: http://www.accellcables.com/products/DisplayPort/DP/dp_dvid.htm I have the two normal DVI monitors working, but when I try to extend the display to the third, I get a message saying the system has detected a problem with the connection through the display port which may limit resolution/refresh rate. I know that all the cables are fine, I have replaced the adapter, the monitors all work, I have tried different monitors through the adapter, and even nothing but the adapter, but I cannot get any monitor to work using it. I am trying to use 2 Dell monitors and an Acer. Have I overlooked something? Is there a compatibiliy issue I missed? Any suggestions as to what I could try? Thanks in advance.

  • How much more productive are three monitors than two?

    - by Sir Graystar
    I am mulling over whether to buy a new monitor, to go along side my current setup of two 24 (ish) inch monitors. What I want to know is whether this is worth the money (probably around £200)? I think most of us will agree that two monitors is much more productive than one when programming and developing (Jeff Atwood has said this many times on his blog, and I imagine that most of you are fans of his), but is three much more productive than two? What I'm worried about is that I will have so much space that one monitor will be used for things that are not related to the task (music, facebook etc.) and it will actually make me less productive.

  • How do you prevent the dock from switching monitors in OSX Mavericks?

    - by Brad Dwyer
    In Mavericks, Apple introduced a "feature" where if you hover at the bottom of any screen the dock pops up on that screen. This is disrupting my workflow as I am constantly having the dock pop up when I don't want it to and then I have to go to another window and hover at the bottom for several seconds to get it to go away so I can click on what I was trying to in the first place. I don't want the dock to move; I want it to stay on the bottom of my right-most monitor like it always has. How can I adjust this in OSX Mavericks?
