  • how to uninstall ubuntu 8 from ubuntu 10 dual boot

    - by umar
    I have ubuntu 8.04 and ubuntu 10.04 on my laptop, and i want to reclaim all the ubuntu 8 space so that i have just one operating system on my laptop. how can i do it? the output of sudo fdisk -l is as follows: sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x31a431a3 Device Boot Start End Blocks Id System /dev/sda1 * 1 4959 39833136 83 Linux /dev/sda2 4960 5233 2200905 82 Linux swap / Solaris /dev/sda3 5234 12852 61192552 83 Linux /dev/sda4 12852 19458 53062657 5 Extended /dev/sda5 12852 19182 50847744 83 Linux /dev/sda6 19182 19458 2213888 82 Linux swap / Solaris i dont know which of sda1, ..., sda 6 etc ubuntu 8 is on. how can i find that out? The actual task is that i think a lot of space is devoted to ubuntu 8, if there is no easy way to get rid of it, then i want to repartition the disk so that about 50 GB of hard disk space is given to ubuntu 10's home folder from the ubuntu 8's home folder. but i hope that there is an easy way to get rid of ubuntu 8 alrogether and just have ubuntu 10 on my system.

  • Launch synergy client on boot in Mac OS X

    - by Herms
    I have a mac as a secondary machine at work. Currently I use synergy on my main machine to share its keyboard and mouse with the mac. I created a launch agent for my user to launch synergy when I log in, and that's working. However, this means I still have to pull out the mac's keyboard and mouse in order to log in. I tried making a user daemon so that it would launch on boot, but I get the following errors in the console: LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Warning>: 3891612: (CGSLookupServerRootPort) Untrusted apps are not allowed to connect to or launch Window Server before login. LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Error>: kCGErrorRangeCheck : On-demand launch of the Window Server is allowed for root user only. LaunchSynergy[52] Tue Jul 14 12:41:44 testmacpro.local synergyc[52] <Error>: kCGErrorRangeCheck : Set a breakpoint at CGErrorBreakpoint() to catch errors as they are returned LaunchSynergy[52] _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL. Is there a way to get this to work? Looks like the Mac's security doesn't want to allow anything to take control of the window while at the login screen. I can understand that, but I'd like a way to override it, as it would make my life a lot easier.

  • Windows 7 doesn't boot when second hard disk is connected

    - by kenshin9786
    I'm sorry for my bad english on beforehand. I have two hard disks, one SATA and another IDE. I have windows XP and 7 on the SATA one, and Ubuntu on the IDE. Both of them boots and works, bios recognizes them, just works. After I installed Windows 7, and connected the IDE drive, it freezes on "Starting Windows" (the black screen with the Windows logo). I unplug the IDE drive, and it starts normally. Windows XP starts normally on both situations (with or without the IDE one connected), same for Ubuntu (it works with both disks connected or just the IDE where it is). The IDE drive is on good status according to SMART. The IDE is first on boot order. It goes to the Ubuntu's grub first, then by default it goes to the Windows 7 bootloader, and then to XP. I think the problem is not about the bootloader or grub. I just read that it can be solved formatting the "problematic" hard disk because Windows 7 cannot handle so many active partitions or something like that. But that's not an option for me, I don't want to lose my Ubuntu nor have it unbootable. How can I solve this without this consecuences I mentioned? Any help would be appreciated.

  • BIOS unable to boot CD or Hard Drive

    - by Gabriel
    Motherboard Intel DQ35MP. HDD Caviar Green 1TB. I'm having problems with my BIOS and/or hard drive/disc drive. Came back from a trip, booted my computer, and realized that the BIOS wasn't booting anymore, just a black screen with no beep sounds. Only fans and lights on. Then I thought it might be caused by the video card, I removed it, and still no BIOS screen. Then I removed the hard drive and voila BIOS screen is back again. If the hard drive is defective then I can check that with a Rescue Disk. I inserted the CD on the Disc Tray but the computer did not respond to it, the screen freezes in black with an "E7" string at the bottom right corner just after the BIOS screen, this happens with or without discs. BIOS settings are set to default, and CD reading is on top of the boot device list. EDIT I removed the BIOS battery, rebooted the CPU, the BIOS screen showed up, and then it freezed in E7. Placed the BIOS batttery, rebooted and same thing, we are stuck with the E7 string. I uploaded a video to illustrate the problem http://www.youtube.com/watch?v=13jPdBcIrBU

  • Reducing video mode switching during Linux boot

    - by Zack
    When I boot up my desktop computer, which only has Linux on it, the video mode and/or console font gets switched four times: When GRUB starts, it switches from 80x25 text to a graphical mode so it can draw a pretty background behind its menu; GRUB then goes back to 80x25 text after I pick something from the menu; When the KMS driver for my video card loads, it switches to a much higher-resolution text mode (I don't know if this is a hardware text mode or not); Finally X starts and it goes graphics and stays that way. I think this last switch does not change the resolution of the video mode, only the graphicalness. I'd like to get rid of as many of these mode switches as possible. Ideally, when GRUB takes over from the BIOS it would go directly to the same high-resolution text mode that the KMS driver selects, and the display would stay in that mode till X starts and brings up graphics. I am under the impression that this is possible by mucking with the kernel command line and/or the GRUB console module load parameters, but I don't know the details. GRUB 1.98+20100706, kernel 2.6.32.15 using Nouveau video drivers. Distro is Debian unstable. Please no answers that involve recompiling anything or cobbling together bleeding-edge kernel/driver combinations, I don't care enough about this to go to that much trouble. EDIT: Tobu suggests setting GRUB_GFXMODE to the full pixel resolution of the monitor, and GRUB_GFXPAYLOAD_LINUX=keep to avoid the mode switch after the menu goes away. This does part of what I want, but winds up being worse overall. There's no mode switch after the menu, but there's still a painfully-slow screen repaint (I should probably just give up on GRUB's gfxmode, it's waaaay too slow at 1920x1200). More seriously, there's now a double mode switch when nouveaufb loads, along with fun-looking error messages in dmesg [ 5.923798] [drm] nouveau 0000:02:00.0: allocated 1920x1200 fb: 0x40250000, bo ffff8801ba5f4600 [ 5.923802] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver [ 5.923821] [drm] nouveau 0000:02:00.0: PFIFO_INTR 0x00000010 - Ch 1 ("PFIFO_INTR" message repeats 400+ times) [ 5.925609] Console: switching to colour dummy device 80x25 [ 5.925802] Console: switching to colour frame buffer device 240x75

  • Windows 7 Won't Boot

    - by Vie
    I recently built a new computer, my fifth one. ASUS Maximus III Formula LGA 1156 Intel P55 ATX Motherboard EVGA 01G-P3-1452-TR GeForce GTS 450 Superclocked 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Video Card COOLMAX RM-1000B 1000W ATX psu Intel Core i7-875K lynnfield 2.93GHz LGA 1156 95w Quad-Core unlocked processor G.SKILL Ripjaws Series 16 (4x4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) memory WD VelociRaptor WD3000GLFS 300gb 10000 RPM SATA 3.0Gb/s Hard Drive Sony Optiarc CD/DVD Burner model AD-7261S-0B LightScribe Windows 7 Home Premium 64-bit It gets hung up on the starting windows screen. When I went to install the OS it did the same thing wouldn't go past the windows logo, so I put the new HDD into my old computer and installed windows 7 thinking it was just an installer error. Put the fully installed HDD back into my new machine and it still gets stuck on the starting windows screen. I've tried most everything I've looked up. Disabled USB, Disabled Turbo Boost, Disabled everything that wasn't essential(just about every configuration I can think of), took it apart and put it back together, took all the ram out save one 4g stick(wouldn't even boot when I did this), did a memory scan which came back successful, I don't know what could be wrong. Only thing I can think of is a compatibility issue somewhere, but I've ran over it again and again and I don't know where there would be an issue like that. Need Backup! .<

  • Win2008: Boot from mirrored dynamic disk fails!

    - by Daniel Marschall
    Hello. I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid) I have following partitions on Disk 0: (1) Microsoft Reserved 100 MB (dynamic), created during setup (2) System Partition 100 GB (dynamic) (3) Data partition, 1.2TB (dynamic) I already mirrored these contents to Disk 1. Its contents are: (1) System partition mirror, 100 GB (dynamic) (2) Data partition, 1.2 TB mirror (dynamic) (3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup. Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't. If I force booting on disk 0: Works (I get the 2 bootloader screen) If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret. I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help. Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting). Regards Daniel Marschall

  • Computer Won't Boot Properly, unless in safe mode?

    - by Mr_CryptoPrime
    I bought a computer today and booted it up, but when I did I only got a blank screen. I checked to make sure it wasn't the monitor by connecting it to my old computer...it worked. I then tried connecting my monitor to both DVI ports and found that the bottom one did work. However, now it just boots up and says "loading windows" and then when the login screen is suppose to come up the screen just goes blank and monitor says "no input, check cord" (or something like that). I tried reinstalling windows and then I was able to log on normally. I used the CD's and reinstalled all the drivers, then rebooted...now I am stuck right back where I started. I tried taking out the RAM and inserting into different slots, that didn't fix anything. I was able to boot up into windows using safe-mode. I suspected that my ATI Radeon 6950 was the issue and downloaded the drivers, but I can't install them on safe-mode. Someone said to install C++ distr. and I tried doing that to fix driver installation problem of "failed to load detection driver" but it wouldn't let me do that either. Please someone help me, I don't want to have to deal with the evil redtape of sending it back to get a replacement!

  • Dual Boot Installing Ubuntu 12.04 with Windows 7 (64) on a non UEFI system fails

    - by Randnum
    I cannot seem to install the correct boot loader for a non-UEFI firmware system. I'm trying to install Ubuntu 12.04 and Windows 7 (64) which are technically compatible with GPT but for windows only if the firmware is UEFI enabled. My system uses the old BIOS system and does not support UEFI. Therefore, whenever I finish my Ubuntu install and try to install Windows I get a "cannot install to GPT partition type" error. Even if I use Gparted to format a special NTFS file format for windows it can't handle the GPT partition style because it doesn't have UEFI. But my ubuntu install always forces GPT during installation and never asks if I want to install the old BIOS style MBR instead. How do I resolve this? Both OS's will install fine on their own the problem is when I try to install the second OS it doesn't recognize any of the other's partitions and tries to rewrite it's own on top of the other. I've tried both OS's first and always run into the same problem. Since there is no way to make Windows recognize GPT without upgrading my Motherboard how do I tell Ubuntu to use the old BIOS MBR on install? Do I have to download a special Ubuntu with a specific grub version? or should I manaually configure my partition somehow to force it not to use GPT? Thank you,

  • Computer not finding hard drives on boot -sometimes-

    - by todd.pund
    Computer specs: Mobo: Gigabyte ultradurable 3 - GA-970A-UD3 Processor: First gen I7 3.2GHZ Ram: 8GB Kingston DDR3 1066 Video Card: EVGA NVidia GTX 460 1GB Hard Drive: 500MB 7200rpm x2 (can't remember brand, sorry I'm at work.) Last week my developer preview for Windows 8 ran out so I put my copy of windows 7 back on the computer. The computer at that point started suffering from frequent freezing and crashing. When I rebooted the computer sometimes it wouldn't find the system HD at all. When I looked at the post screen it seemed to show that it wasn't finding either of the HDs. Then yesterday when turning on the computer I just got GRUB as a message (not a GRUB prompt, just GRUB) I haven't had a dual boot of Linux for at least a year. I loaded windows 7 recovery console from the disk and ran: bootrec /fixboot bootrec /fixmbr Which did not help. At that point I just installed Ubuntu 13.04 over the windows 7 install and still received the GRUB post. I went into the BIOS and switched the Hard Drive priorities and then it loaded into Ubuntu fine. For several days everything was just hunky dory until I installed the Ubuntu version of Steam, install Portal and tried to run it. At that point the computer froze and after hard rebooting couldn't find the hard disks again. Then after restarting the system it loaded up fine again and no issues since. (I have not tried to launch portal again). My next thought is to remove the system hard drive and try to use the secondary as the master to see if the primary HD is bad. I'm sorry if this has been confusing, I'll answer any questions I can. Any thoughts?

  • Install Debian stable linux ISO from USB to dual boot Windows

    - by tgkprog
    I want debian as dual boot with my windows vista, Free'd up 50GB in my d drive. Plan to use 40 for debian install, 6GB for swap space Have a 16GB USB drive Downloaded http://unetbootin.sourceforge.net/ Downloaded DVD files of stable debian-7.0.0-amd64-DVD-1.iso ( debian-7.0.0-amd64-DVD-2.iso and 3) After I choose HD install, unetbootin says place the ISO in the same place. but I have 3. do i need to merge them? if so any freeware to do that? can i do it with 7zip? when I extract with 7 zip there are classes between the 3 ISO files. Just over write? Options to merge (format etc for 7zip) ?

  • What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?

    - by Denja
    Hi Linux Community, I find my self struggling with the slowness of windows OS once again. It's Time to change with the Ubuntu 10.10 64bit for I like to use a faster Operating System. My Hard Disk laptop has a RECOVERY and HP_TOOLS partition they are both Primary. I Have the System Recovery DVD for Windows 64bit should anything bad happen. Here's the layout I used with windows before: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,ad Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I wanted to make: * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows DATA partition (user files) NTFS - 120GB(Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Extended)(sda3) (Ubuntu 10.10 64bit) * Linux home Ext3 - 90GB (Extended)(sda4) (Ubuntu 10.10 64bit) * Linux swap swap- RAM size, 3GB (sda5) * Linux root Ext3- 18GB (Extended) (sda6) (OpenSuse or Puppy or kubuntu) Here is my New Ubuntu 10.10 64bit layout in use now: * SYSTEM partition NTFS 199MB (Primary) (sda1) * (C:) Windows 7 system partition NTFS - 90GB (Primary) (sda2) * (D:) Windows 7 RECOVERY partition NTFS - 12,90GB (Primary) (sda3) * Linux system partition EXTENDED - 195,1GB (Logical) * Linux root Ext4- 10GB (Extended) (sda4) * Linux swap swap- RAMx2 size, 6,1GB (sda5) * Linux home Ext3- 179GB (Extended) (sda6) When I installed Ubuntu,I didn't know if I could wipe all previous partitions,because of the RECOVERY partition. So I just made the space for my extended partition with GParted by deleting the HP_TOOLS (Fat32). By doing this I managed somehow to install Ubuntu 64 with Success. And I also made the partitions for the swap or a third Linux OS as Jordan suggested. But I couldn't actually make the partitions for the shared NTFS.(no option!) Question 1: What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?? Thank you in advance for your advises and suggestions and Happy New Year to All!!

  • Using an old PC case and power supply as a HDD Enclosure?

    - by mexiq
    I have 5 HDD and my computer is not handling the situation very well. hehe There are some towers that I can buy to put 4 of my drives out, but I'm thinking that I could use the power source of a failed computer I have and use it to power the 4 (or at least 3) of the drives. The data cables (SATA) will remain connected to the working computer (so no USB solution). The problem is that the power source will not work unless it is connected to the failing computer motherboard. Is there any way I could use the power source without plunging it to the old motherboard? Any "HOW-TO" links may be useful as well.

  • P4 vs. i3/i5 *T in power consumption and performance [migrated]

    - by Walter Zomb
    I am running an Intel P4 prescott with HT on my home server (linux file server on encrypted disks on software-RAID5 and virtualisation host for three further machines). The performance for this purpose is really okay. When the system is idle it consumes about 140W power. I am considering buying a new mainboard for an e.g. Intel i3-2100T or an Intel i5-2390T. Both are low power CPUs with a TDP about 40W. Has anyone experiences how much power a recent mainboard with one of these CPUs an 3-4 'green-energy' disks (6W each) consumes? Do I get underneath the 100W threshold? What's about the performance of these low power CPUs? Are they comparable to an Intel P4 with HT? regards, walter

  • Why does unpartitioned Hitachi HDS5C3020 drive start consuming 50% more power 15 minutes after boot?

    - by Pro Backup
    In a Debian 6.0.6 system there are 74 pieces of 2TB Toshiba DT01ABA200 drives. These drives are identified as Hitachi HDS5C3020BLE630 drives running firmware revision MZ4OAAB0. 64 Drives attached via HP SAS expander cards to an LSI 2008 SAS controller, another 5 drives are connected directly to the mainboard, 4 drives are connected to a Sil based PCI controller and last 1 drive is only powered and has no data cable connected. The controller LSI and Sil card's their onboard BIOS are both disabled and the mpt2sas and sata_sil modules are removed from the Linux debian 2.6.32-5-amd64 #1 SMP Sun Sep 23 10:07:46 UTC 2012 x86_64 GNU/Linux kernel. The mpt2sas module is loaded after boot using a modprobe command in /etc/rc.local. These 74 drives are not partitioned, neither formatted and also not mounted. The system consumes: with 0 drives: 70.6 - 70.9 Watt (also 15 minutes after boot); with 74 drives: 330 - 360 Watt, just after boot (is equivalent to 3.5 - 3.9W per drive in idle state); with 74 drives: 420 - 466 Watt, each time in the 15th minute of uptime (is equivalent to 4.7 - 5.3W per drive in idle state). The drive specification lists 4.7W as read/write, and 3.3W as idle power consumption. The increased power consumption is most likely on the 5V line, because after roughly 1 minute an "over current protection" (OCP) of the power supply (PSU) shuts down the power. The used PSU is a single rail model with an OCP of 122A on the 12V line and 55A on the 5V line. Regression: It doesn't matter whether the drive its APM value is set to disabled or 1 (maximum power saving). The operating system records no read/write activity in /proc/diskstats. The values there are identical (28 read, 0 write operations) as immediately after the modprobe operation. Can't test what happens when booting into the mainboard it's BIOS - to exclude any OS intervention - because the Super Micro X8SI6-F mainboard running firmware 06/27/12 has a bug that incorrectly reads a +74.0 C CPU sensor temperature as "High" in BIOS mode, and shuts down the power after 1 minute. What might be causing the drive read/write activity on all drives in the 15th minute after boot and how to prevent it from happening?

  • Is the APC BR700G UPS (or similar) compatible with Active PFC power supplies?

    - by David Zaslavsky
    I'm looking at getting a UPS for my home computer. So far the APC BR700G looks very promising, except for one thing: one of the reviews on Newegg says that this UPS does not work with a power supply with Active PFC. Pros: Unit looks great, built well, very heavy, was excited to use it. Cons: Didn't research enough - many newer power supplies like my corsair 750w (and yes dells and other mainstreamers sell them too) that I bought last year have a feature called active pfc (power factor corrected). The signal for this backup battery doesn't fully support that feature and can cause issues. You can find an article on APCs site if you search their user forums for PFC. And the power supply in my computer is, in fact, an Active PFC PSU. I've already found one answer on this site claiming that it's not an issue, that "most quality supplies these days have PFC and work just fine with a UPS." That disagrees with the review on Newegg. Can someone explain this discrepancy? Also, what is it exactly about a UPS that makes it incompatible with an Active PFC PSU? (if anything) Is there some way to tell based on the technical specifications, or do I just have to hunt for reviews online to avoid wasting my money? While any input would be appreciated, I would prefer to get an answer from someone with actual experience with similar UPS's and Active PFC power supplies, who can tell me whether it works or not.

  • Reseting Macbook Pro keyboard and trackpad's power usage on Windows?

    - by Dan the Man
    I recently installed a utitlity for Windows (ASUS Ai Charger) which modifies the USB ports on the computer to output more power (for charging iPads, etc). The problem is, I believe it is also giving more power to my keyboard and trackpad. And now, neither devices are working at all, yet they work on Mac OS X. So does anyone know the amount of power MacBook Pro (2007) keyboards and trackpads use, and how I can set these settings in Windows 7?

  • Suspected power supply issue? PC repeatedly whirs for some seconds and then dies.

    - by benwebdev
    I've come home today and switched on the PC I've built a few months ago only for the machine to whir for a few short seconds and then die. It repeats this until I disconnect the power lead. Nothing is output to the screen and this cut out happens very quickly after switching it on. What could this be and how could it be fixed? Is it the power supply? I'm in despair :-( My spec is below, everything is new and was bought and assembled within the last 6months, system has been fantastic until now.

  • Is it safe to use an IDE to SATA power adapter for an extended period of time?

    - by qwertymk
    I just bought a computer from HP and they failed to include SATA power connectors with the power supply other then the one HD and DVD drive. Meanwhile I have two IDE to SATA power adapters that came with my "USB 2.0 to SATA/IDE cable" http://www.amazon.com/USB-2-0-SATA-Cable-Adapter/dp/B001OORN06 3rd pic on the left. I was wondering if I would just open up my computer and use it to plug it my SATA drives to the IDE power sources and mount it to the motherboard, would it damage my drives in the long run or have any other significant effects. A friend told me he knows people who have had their HD burn out because of this
