  • Mac questions: installing TrueCrypt and Windows 7

    - by KeyStroke
    Hi, I'm about to buy a Mac laptop, but I need to be able to use Windows 7 as well + encrypt the HDD with TrueCrypt (or a better alternative for the mac). My questions are: 1) How well does Windows 7 perform under boot camp? 2) Will I be able to encrypt the whole HDD (with TrueCrypt or whatever else) and still use boot camp to dual-boot? Your help is much appreciated

  • MySQL multiple instances: can you specify a separate general_log/general_log_file option?

    - by gravyface
    Have two working MySQL instances as well as the default instance. I have general logging enabled on the default; this is working fine. On the second instance, I've added: general_log = 1 general_log_file = /path/to/log/file under [mysqld1]. Restarted the instance (using mysqladmin and confirmed it was not running with mysqld_multi report 1), started it back up again, and the only data in the log file are the connect statements from when mysqld_multi report 1 was executed. Are all the instance #1 queries just being logged to the default instance general log file? The default instance is quite busy and has identical database names, tables, etc. so it's difficult to figure out right now.

  • ffmpeg not using all cores

  • Removing grub and getting a dual boot of Linux Mint and Win 8.1 working after failed attempt

    - by ThroatOfWinter57
    I gave the details of my problem at reddit: http://www.reddit.com/r/linuxquestions/comments/27qrun/more_specific_questions_about_failed_win_81mint/ tl;dr: I deleted the /, /home, and swap partitions I made for mint after realizing my installation couldn't be booted into and gave the space back to my windows partition. Running boot-repair on my mint live session messed stuff up. Now I can't even boot to my live session usb because grub is left over. Windows 8.1 does work though.

    - by ianfuture
    Is it possible to set up a PC so it can Wake on Lan and then have the option of which OS to boot into? I want to have a secondary PC with Windows and a *nix variant installed.

Any recommendations on how to do it or where I can get more info on how to do it? Thanks.. Ian

  • How does bridged networking work?

    - by agz
    How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

  • Multiple nt52 entries in bootmgr

    - by SLaks
    I have a machine with Windows XP, Server 2003 R2, and Server 2008 R2. Right now, bootmgr has one entry for Server 2008 R2 and one entry for ntldr, which then leads to the ntldr boot.ini menu. Is it possible to add two different nt52 entries on two partitions so that I can access all three OSes from the bootmgr menu? Right now, Server 2008 and XP are in logical drives on an extended partition, but (I assume) I can image them onto basic partitions if necessary.

  • Mac OS X: All bootcamp options start Windows

    - by Brian Heylin
    I just installed the latest security update on Mac OS X (installed on 2-10-2010). On restart my Mac booted in Windows 7, which I had installed previously and was set not to boot by default. I tried to restart holding the alt key, and selected the Mac OS X partition, but still the Windows 7 partition boots. It does not matter what partition I choose, Windows 7 always boots. I took a look in the OS X partition and noticed that the admin home folder is empty, or at least Windows is not showing any files there. There is another user on OS X and I can see their files no problem. This has me stumped, has anyone any suggestions for a finding a solution?

  • Best way to Duplicate a Laptop's Hard Drive One-to-One

    - by Urda
    I have a Lenovo X61 Tablet computer, with a plain SATA drive inside. I have windows 7 and Ubuntu 9.10 dual booting on the computer. I want to back up both of these OS's, and their special partitions (Windows 7 has one, and of course the Linux Swap). I want a one-to-one backup, all of my mission critical data is already backed up, but I would like to get a snapshot, and store it on a larger file server at home for quick recovery. What is the best approach to do this?

  • Sync my files across multiple computers

    - by EnderMB
    I do a lot of work on my home computer, ranging from programming, writing stored procedures and writing documentation and reporting. A lot of this work is university related and constantly swapping files across several computers is annoying at best. I have a large final-year project coming up and I'm going to be sharing this work amongst home and university and require some kind of online storage that provides version control for my programs, as well as my Word documents, PDF's and saved academic papers. Are there any good solutions for my problem?

  • dual boot preinstalled windows 8 laptop with windows 7

    - by sarathi
    I am having a hard disk in gpt partition style and Windows 8 is pre-installed in uefi mode. While trying to dual boot using usb bootable disk(using rufus,gpt partition style,fat32),it displays "Windows is loading files", then while displaying "Starting Windows" it hangs. So, I tried to install it inside Windows using setup.exe. Everything was running fine, but when it gets self restarted again, it got stuck at "Starting Windows". When restarted in Windows 8, it showed a htm file stating that "Windows cannot be installed on a computer using battery power. If the battery runs out of power during the installation, you might lose data. To continue the installation, plug in the computer's power adapter." I am sure that power adapter is connected. I Googled a lot on this, but I didn't get solution.

  • AMD 700, 800 series chipset. I'm lost.

    - by Shiki
    I've been an Intel / NVidia user ever since I started using computers. Intel really gone up with the prices, and they won't get cheaper. So I decided to get an AMD. But WHICH one? I mean.. not shopping question but.. what are the differences? Like: 880GMA comes only with a single PCI ex and it looks like a chinese replica (no offense). While 890FX comes with 5PCI-ex for QuadCrossfire. Also.. what's the deal with 7xx series? I mean.. its the same price. Yet its older? Or why is it 7xx? Isn't there a single chipset between? Not chinese YET it's durable/fine for long-term usage? What it should know (desktop stuff): NVidia GPU (Zalman AMP2 GTX 260^2 (one card)) Phenom 1090T cpu A somewhat good audio. Any ideas which is the chipset I'm searching for? If this sounds too much of a shopping question, feel free to edit. I just want some clarification on these chipsets.

  • VMWare Ubuntu guest multitouch touchpad

    - by Petr Marek
    Related: Use Synaptics Touchpad Scroll in VMware Guest I've read that it's not possible to enable multitouch in vmware guest. What confuses me, is that when I use something special (like two finger scroll) in guest OS, I can see the cursor change to the scrolling one. Is this some kind of virtualization bug or is there a possibility that I can enable multitouch in guest? Host: Windows 7 Guest: Ubuntu 12.04

  • mysqld_multi stop doesn't seem to work

    - by gravyface
    mysqld_multi stop 1 followed by (repeatedly, a few moments later) mysqld_multi report 1 returns: Reporting MySQL servers MySQL server from group: mysqld1 is running The instances work fine and when I reboot, I have to start the instances to get them to come back up (a separate issue I need to resolve), but the stop command doesn't seem to do anything. It truly doesn't stop the instance because in the instance log file I see this: 120619 11:12:39 mysqld_safe A mysqld process already exists after trying to run start after.

  • MacBook: Can't boot into Linux partition after installation.

    - by Otto
    Hello I just installed Ubuntu. I created a partition in MacOSx using Disk utility, then deleted the partition and installed Ubuntu on the free space created. After the installation, Ubuntu said it would reboot. I hang on shutdown (which is normal, as google told me), so I used the power button to turn the MacBook off. Now I want to boot into Ubuntu. Pressing option/alt on startup only shows me the MacOSx and Windows partition. Also, the Linux partition isn't showing up on my MacOSx desktop. And in Disk Utility, I can see 3 grayed out partitions: "disk0s4", "disk0s5" and "Linux Swap". What can I do to boot into Ubuntu without losing my other partitions? Thank you for your help.

  • Disk Error on Boot (Possible boot sector issue)

    - by Choco
    I own a 4-5 year old Dell Dimension E510 with Windows XP: Media Center Edition. I have 2 drives installed: C Drive: Windows XP: Media Center Edition G Drive: 2 partitions: Windows 7 (beta) Windows XP (professional) That is also the order they are connected. The C Drive is my primary drive. When I attempt to boot the computer, the bios loading screen appears normally; the progress bar moves and it's fine. The very next page, however, supposed to be a boot choice. When I installed Windows 7 onto the G Drive in context of the C drive it added a boot selector to the C drive's boot sequence. It gives me the option of booting Windows 7 or Windows XP: Media Center Edition. However, my problem is now this: After the bios screen I previously mentioned, instead of a boot selector, I receive the following error: A disk read error occurred. Press CTRL+ALT+DEL to restart. The drive is spinning up normally. I hear no odd noises/clicks/scraping coming from it, even after disabling the other drive to listen to it carefully. According to me, it's a boot sector issue. I have never experienced this before, but maybe during a recent shutdown, Windows XP: MCE errored out and ruined the boot sector. Dilemma! I don't have the Windows XP: MCE disc, because it was installed by the factory. I have accessed the hidden partition on the drive before (you hit a key combination on the bios screen and it comes up with an interface to fix your drive). However, I don't want to reformat the drive (which is what the interface gives me the option to do). I want to possibly fix the boot sector. How can I achieve that?

  • How to turn off the binary log for mysqld_multi instances?

    - by netvope
    MySQL supports running multiple mysqld on the same server. One of the ways is to use mysqld_multi. If the default MySQL server instance (as configured in the [mysqld] section in my.cnf) uses log-bin, it enables the binary log for all the other instances ([mysqld1], [mysqld2], etc). How can we override the setting for the other instances? We tried putting log-bin= or log-bin=OFF under [mysqld1], but that won't disable the binary log.

  • How to change drag & drop behaviour in Windows 7's explorer?

    - by Pekka
    I have a new touch screen, and am playing around with its functionality. The most productive use for me is organizing files (literally) by hand. It's fun working through a list of files, dragging and dropping them to the right locations using your index finger. It feels better on the wrist than mouse-clicking, too. The only problem is that when I drag & drop files across drives in Windows 7, the default behaviour is to copy the file instead of moving it. I know I can influence this using right click, but that is of course no option in my situation. How can I change the default drag & drop behaviour in Windows 7's explorer?

  • Install GRUB on NTFS

    - by karatchov
    I would like to install 2 completely independent instances of Windows XP (no data should be shared) in my computer within 2 different primary partitions. I know that grub can handle booting them correctly, but I have no idea if it's possible to install it and configure it within a 100% NTFS system and without any extra linux partition/distribution.

  • How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

    - by Marco Mariani
    I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks
