• Partition Hard Drive For Data

  - by user211779

  Greetings ~ I am a new Linux/Ubuntu user. For various reasons (mostly my own ignorance) I am on my third install of Ubuntu 12.04. I want to partition the hard drive to create a drive for data and personal files in case I ever have to install again. I have been struggling all afternoon to make a gparted live USB. Tuxboot looked like the answer but I get an error message when using it. So, I am asking for help. Ultimately, I want to partition the hard drive for data and personal files. What do you recommend?

• Partition disk for dual boot Windows XP and Windows 7 (shared files)

  - by soupagain

  I wish to dual boot Windows XP and Windows 7. I wish to have my documents available from both OSes. Do I create a single partition and it just works? 2 partitions, one for each OS? 3 partitions, one for each OS and one for the "my documents"? [EDIT] I used 3 partitions, one for each partition and one for docs which is mapped as a separate drive. Works perfectly. The only think you need to do is hide the other OS partition, ie for Windows XP, hide the Windows 7 partition. You do this from partition manager.

• read data on ntfs partition - ubuntu

  - by albert green

  Hi, I had a win xp with an NTFS partion for programs (c:) and I installed ubuntu 10.10 on it. I will use ubuntu from now on. On the disk there was a space for the NTFS partition and free space. I created in the free space a new linux partition. So the new linux partition is a ext3. now from ubuntu I used the disk utility and saw that the windows is marked as free space. I had only one possibility, which is to create a partition, so I did as NTFS. I did NOT format it. I don't care about the windows system, I just need to access the program files folder on that partition and get my chrome bookmarks. I forgot to save them before the installation of linux. do you think it is possible? if so how? thanks.

• Linux: Combine two partitions?

  - by Jakobud

  This workstation is running Fedora 11. It has 4 HDDs raided into 4 partitions: / (31 gig) /boot (134 meg) /data (140 gig) /FC12 (31 gig) The previous employee that used my current workstation set it up this way. He apparently created the FC12 partition to test a Fedora 12 installation. I don't need Fedora 12 so I wiped that partition and now I'm wondering if its possible for me to combine the /FC12 partition into the / partition, so that the / partition will now be 62 gigs. Is this possible? If so, how? Can it be done w/o reinstalling the OS? I've toyed with Fedora's LVM admin interface but it seems very basic and there doesn't seem to be anything about combining partitions. I've also messed with other HDD utilities that are in Fedora (Palimpsest Disk Utlity) but all it seems to be able to do is mount and umount partitions.

• Create Hidden Partition on USB

  - by Francesco

  I need to split an USB flash disk into two USB drives, each one with its own drive letter, but one of these has to be hidden. In the non-hidden partition I want to place my software, and in the hidden partition I need to place some files that are required by the software in order to work. Moreover, only the software may read, write, delete or execute the files in this partition. I thought to use a little partition viewed as a CD-ROM drive, as they do in many flash drives, but this solution does not allow to write other data in a second moment, and it's visible to the user that can read the file. Obviously the software must be able to access to partition and read, write, delete or execute the content. Is there a solution to do so, possibly that work also on Linux?

• EFI Partition Types

  - by Will

  Another employee was working with a mounted VHD and was using diskpart on it and I'm not sure if he messed something up or not. I think it's fine but I wanted to double check. We have a Windows 2008 x64 machine that boots with EFI because of the large disks in the system. What should the different labels be within Disk Manager for this system? Here is what is currently set: 200 MB Partition - EFI System Partition C Partition - Boot, Page File, Crash Dump There should not be an active partition under EFI, correct? Also, is there supposed to be a "System" label in addition to "EFI System Partition"?

• Lost HDD partition to clean command, testdisk unresponsive

  - by Sujay Anjankar

  I accidentally cleaned my external HDD by the clean command in Diskpart and got a full sized heart attack after that. I did some research and I have tried a number of tools already. To name a few: Testdisk Recuva Partition Find and mount Eassos Recovery I have even tried some other dumb sounding tools, but none of them could find the lost partition. They just show "no partition found". Testdisk shows Partition sector doesn't have the endmark 0xAA55. The file recovery softwares list the files, but none of them seem to be able to restore the lost partition. I need to recover the disk as it was. Any help would be much appreciated!

• How to install windows 7 from scratch on a disk which already contains partitions

  - by rangalo

  Hi, I have following partitions on a 1 TB disk. 14 GB UNKNOWN recovery partition 100MB NTFS System Reserved partition for Windows 7 448GB NTFS Windows 7 system partition 468GB NTFS Data partition for windows 7 Now because of the problems mentioned in my other question here I got a brand new windows 7 cd and want to install it from scratch after deleting all the extra partitions. But windows 7 installation doesn't give me such options. It refuses to touch the 14GB Recovery and 100 MB (reserved by previous windows 7) partition. Any ideas ? Note: Because of it is a dynamic disks most of the freely available tools refuse to delete the partitions on the disk. regards.

• Can't find second partition on encrypted drive with two partitions

  - by Thomas Uhrig

  I have a drive with two partitions, a system partition (Windows 7) and a partition just for data. Both are encrypted with the same password. I didn't had any problems, but yesterday my laptop gets broken. Now, I'm trying to connect the drive via USB to a new laptop and read it. The problem is, that I only see the system partition, not the one with my data. When I click on "Select Device", I can see my drive as "Harddisk 1" with 300 gb. But I only see a single partition "Partition1" with 117 gb. I'm unable to find the second one. It's not a hidden partition. Any ideas? Thanks.

• Merge Publication Data Partition Snapshot generation

  - by David Osborn

  I have a merge publication in SQL 2008 R2 with data partitions and I am wondering when I should generate the snapshots for the data partitions. I get an error sometimes when bringing a new subscribe online related to the partition snapshot being out of date and I am wondering if this has to do with the publication snapshot being scheduled at the same time as the partition snapshots. I'm not really sure how the partition snapshot gets generated, but it appears maybe it is getting generated before the publication snapshot. If this is the case how should I be scheduling the partition snapshots to get generated? Should I set them to run x number of minutes after the publication snapshot? this seems kind of poor to do in case the publication snapshot takes awhile or fails. It seems to me the publication snapshot should just run the data partition snapshot agents when it is done if this is the case.

• WindowsXP+7 on C:/D: :moving the System Partition

  - by user938921

  I had installed Windows 7 on a separate 20gig partition, and I'm absolutely loving it! Plus I can now dual-boot, with my original WinXP residing on the C: drive. But I'm running out of disk space on D:, and I was able to shrink C: and expand D:. But now I would like to make D: not just a Boot Partition, but an Active System Partition, without losing my ability to boot into Windows 7 (since it was created on a separate D: partition, not the current Active System C: Partition). Any advice?

• Is there a software in windows that enables you to boot from a specific partition?

  - by Tono Nam

  I use acronis true image to mount images to my primary partition and it works great. lets say I have 3 partitions on my hard disk and all of them each is 600 GB. In the 3rd partition I keep files (documents, pictures etc), on the first partition is my primary partition where the operating system runs (windows 7). And in the 2nd partition is empty. I have an image of my primary partition and I save that image in my 3rd partition (50 GB is the size of the image so it fits in the partition number 3) and in an external hard drive. I know it is possible to install a new operating system in partition 2 such as windows xp but the only problem is that once I install that how could I tell the computer to boot from partition 1? is there a way to switch back and forth just like it's possible in the mac?

• VMware Fusion won't boot my Boot Camp partition

  - by Sean

  I have a Boot Camp partition on my MacBook that I would ultimately like to convert to a VMware virtual machine image. I've installed VMware Fusion and tried to start up my Boot Camp install using the Boot Camp button on the initial welcome screen. It brings up the "VMware Fusion is preparing your Boot Camp partition to run as a virtual machine" dialog, but afterward it shows an error dialog with the following message: Boot Camp partition preprocessing failed. You may not be able to boot your Boot Camp partition as a virtual machine. It then tries to boot the new VM, but it blue screens during the boot process. The info on the blue screen doesn't provide much in the way of help though. Running chkdsk has no effect. After searching around, some people recommended using VMware's stand-alone converter utility from within Windows to create an image, but the utility said it couldn't create an image because my disk uses a GUID Partition Table (GPT). I'm wondering if this is why it can't boot my BC partition from Fusion. Has anyone else run into this and found a fix?

• How to change my W2k8 System Partition?

  - by Chris May

  On my Windows 2008 server, my C: is 1.5 TB, and the partition is marked as: Healthy (Boot, Page File, Active, Crash Dump, Primary Partition) and somehow I ended up with a 2GB D: that is marked as Healthy (System). On this D: drive are only a few MB worth of files (bootmgr, boot folder, bootsect.bak), but all Windows files are on the c:. I've done everything I can to remove the (System) mark. I tried using bcdedit, I tried marking the C:partition as "Active", I tried using bootsect.exe to assign the C: drive as the boot partition. Maybe I didn't do one of those steps correct, but I've tried everything I can. When I got my new Dell Poweredge T710, I didn't bother removing their 2 small drives before I put in my 2 new large drives. So I think when I installed W2k8 Server, maybe dell left some bootable partition on their drives to help me install the OS, but I never used it and just booted right from the install CD. Can anyone help me remove the (System) mark from the D: so I can remove the D: partition and still boot to the C:? I know I could remove the D: drives and reinstall windows, but I'm trying to avoid a total reinstall.

• Backing up default windows installation with dd from linux running on another partition - is this fe

  - by Marek

  I am preparing to reinstall my system. I am thinking about creating a multi boot with a linux distro+Windows 7 to choose from when starting up. I would love to be able to skip all the hassle of reinstalling Windows and all programs when it starts becoming too slow in the future, thus I would like to mirror my fresh Windows system partition with some programs preinstalled. I am thinking about installing Ubuntu, making a partition for windows, installing windows with the basic environment (Visual Studio, Office, etc.) then booting into Linux and making an image of the windows partition with dd. I am not familiar with linux at all so I am a little afraid something may go wrong along the way. Is it possible to do it this way? Will I be able to partition my existing disk for multi boot easily after I install Ubuntu? Will I be able to recover the Windows partition easily using dd when I will need to re-create a fresh windows partition in the future? What other (better) approach can you recommend to achieve the goal of easy disk mirroring (for free)?

• Dell XPS 15 L502X hard drive Partition

  - by Mohan Gajula

  I have a situation here. I got my new Dell XPS 15 Laptop. The configuration of hard drive is as below : Volume 1: (OEM Partition): 133MB Volume 2: OS (C:): 685.25 GB Volume 3: Recovery : 13.25 GB Now, I am trying to re-partition my C Drive to have a C: drive with 100 GB and a new drive with 585 GB. Earlier, I tried using the Windows 7 Disk Management to shrink and extend the volume. That lead to the OS and hard drive not working. Dell Tech support tried to fix the issue, but they were not able to fix the issue online. Later a Dell Technician arrived my place, and replaced the hard drive with a new hard drive. Please help me re-partition the C: Drive with 100 GB, and new D drive with 585 GB. I don't want to lose my Recovery Partition. SOLUTION As Suggested by KCotreau below , I have done exactly. I have resized the C drive to 100 GB. And then applied the changes. Windows got restarted. On the boot screen, the partition was taking place. It took around 30 mins ( approx. ). Once after restart, I can see my C drive is 100 GB. Now opened the Easeus again. And created a new partition for the free space ( 585 GB ) this took 10 seconds to create. Here goes the screenshot after partitioning. Thanks to KCotreau. You are amazing.

• Allignment of ext3 partition on LVM RAID volume group

  - by John P

  I'm trying to add a partition on a LVM that resides on a RAID6 volume group and fdisk is complaining about the partition not residing on a physical sector boundry. My question is, how do you calculate the correct starting sector for a partition on a LVM? This partition will be formated ext3. Would it be better to just format the LVM directly instead of creating a new partition?

• Data recovery from corrupt Ubuntu partition/directory (question about a previous answer)

  - by JoshMaurice

  I have an Ubuntu installation that won't boot anymore. I asked my previous question about it here: http://superuser.com/questions/15916/ubuntu-chkdsk-equivalent Bolotov replied: As I see from your previous question you can boot Windows so you could use dskprobe from Windows XP Service Pack 2 Support Tools to make sure that fs type is correct ... but it's already correct fs type 7 is NTFS. Message "The type of the filesystem is RAW. CHKDSK is not available for RAW drives." means that windows can't determine fs type for some reason. As we see fs type is correct. To run Chkdsk on your Windows partition you can install Windows Recovery Console, boot in recovery console and check your disk. After checking the disk you will gain access to you c:\ubuntu\disks. I think you can mount your linux partition (which is in file) as usual loop-back device: mount -o loop [path to your linux-loopback-partition] But you should mount windows patrition first. So now I'd like to know: Within the recovery console I will be issuing the commands "chkdsk -r" and then "mount -o loop [path to windows partition]" and then "mount -o loop c:\ubuntu\disks", correct? I do have a ("corrupt and unreadable") c:\ubuntu\disks directory so that appears to be the correct path to the linux partition; do you know the path to the windows partition? would that be just "c:\"?

• Move EFI System Partition to another drive

  - by Pincopallino

  I had a Windows 8 installation on an HDD, using UEFI as boot. The HDD has the following GPT table: DISKPART> list partition Partizione ### Tipo Dim. Offset --------------- ---------------- ------- ------- Partizione 1 Ripristino 300 Mb 1024 Kb Partizione 2 Sistema 100 Mb 301 Mb Partizione 3 Riservato 128 Mb 401 Mb Partizione 4 Primario 390 Gb 529 Mb Partizione 5 Primario 540 Gb 390 Gb (I apologize it's in Italian, but the translation is quite straightforward). I recently bought an SSD drive, connected it and installed a fresh Windows 8. Now I have a working dual boot, but the UEFI partition is on the HDD instead of the SSD. Here's the SDD partition list: Partizione ### Tipo Dim. Offset --------------- ---------------- ------- ------- Partizione 1 Riservato 128 Mb 1024 Kb Partizione 2 Primario 221 Gb 129 Mb I think that the best solution would be to have it on the SSD for two reasons: the first is performance (I guess it would be a little be faster on the SSD due to the spin up time for an HDD, but I may be wrong about that) second reason is consistency. As I plan to use only the Windows 8 installation that is located on the SSD and I'm probably going to erase the system partition on the HDD to use it as a data storage device, I think that the boot partition should be on the same drive as the OS. So the question is how do I move the EFI System Partition to the SSD?

• Backing up a Windos 7 partition from Macbook with no OS X

  - by mattcodes

  I have a 3 year macbook with Windows 7 installed as 40gb and OS X as 40gb (80gb HD). I want to remove OS X as Im at the limit of 40gb on Windows and I have not logged on to Mac OS X since installed Win7 (dont flame me). So I want to delete OS X partition and expand my win partition to 80gb BUT I still would like to be able to regularly (once a week/month) backup my Windows 7 partition - its took a while to setup everything up right - not just docs and programs - so when the hard drive dies I want to be able to restore the partition and boot away, (the daily volatile bits I can pull down from dropbox and project from soure control). With Mac OS X I could use Winclone - and this worked flawless last time the HD failed with XP but with the absence of OS X I will need something else. Im thinking can I use a Linux Live boot CD along with an external USB hard drive. Boot from CD and then dd? the partition to the USB? What linux distro live CD should I use? I say dd as if I know what am taking about (I dont) is this the best way to backup a partition (when it will be restored to same hardware as bootable) ? What command?

• What is the right 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 ever slow and buggy windoze OS once again. It's Time to change with the Ubuntu 10.10 64bit as a really faster Operating System. My Hard Disk laptop as a RECOVERY and HP_TOOLS partition they are both Primary. I Have the System Recovery DVD for Windows 64bit should anything happen. Here's the layout I used with windows before: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,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 want to make based on your answers * (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 - 100GB (Primary)(sda3) (Ubuntu 10.10 64bit) * Linux swap swap- RAM size, 3GB (sda4) * Linux root Ext3- 15,9GB (Extended)(sda5) (OpenSuse or Puppy) Here is my New Ubuntu 10.10 64bit layout in use now: * SYSTEM partition NTFS 199MB (Primary) (sda1) **Partition 1 does not end on cylinder boundary.(?)** * (C:) Windows 7 system partition NTFS - 90GB (Primary) (sda2) * (D:) Windows 7 RECOVERY partition NTFS - 12,90GB (Primary) (sda3) * Linux system partition EXTENDED - 195GB (Logical) * Linux root Ext4- 10GB (Extended) (sda5) * Linux home Ext3- 185GB (Extended) (sda6) I didn't know if I could wipe all previous partitions when i installed Ubuntu because of the RECOVERY partition so I just made the space for my extended partition by deleting the HP_TOOLS (Fat32). By doing this I managed to make and successfully install Ubuntu 64 but I couldn't actually make the partition for the swap or a third Linux OS. Question 1: What is the right 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!!

• Warning: cast increases required alignment

  - by dash-tom-bang

  I'm recently working on this platform for which a legacy codebase issues a large number of "cast increases required alignment to N" warnings, where N is the size of the target of the cast. struct Message { int32_t id; int32_t type; int8_t data[16]; }; int32_t GetMessageInt(const Message& m) { return *reinterpret_cast<int32_t*>(&data[0]); } Hopefully it's obvious that a "real" implementation would be a bit more complex, but the basic point is that I've got data coming from somewhere, I know that it's aligned (because I need the id and type to be aligned), and yet I get the message that the cast is increasing the alignment, in the example case, to 4. Now I know that I can suppress the warning with an argument to the compiler, and I know that I can cast the bit inside the parentheses to void* first, but I don't really want to go through every bit of code that needs this sort of manipulation (there's a lot because we load a lot of data off of disk, and that data comes in as char buffers so that we can easily pointer-advance), but can anyone give me any other thoughts on this problem? I mean, to me it seems like such an important and common option that you wouldn't want to warn, and if there is actually the possibility of doing it wrong then suppressing the warning isn't going to help. Finally, can't the compiler know as I do how the object in question is actually aligned in the structure, so it should be able to not worry about the alignment on that particular object unless it got bumped a byte or two?
