System_drv and lenovo_recovery partitions

Have a laptop i want to rebuild from scracth with windows 7 enterprise.
I have no problem keeping the partitions on there however I always have an OS/programs partition and a data one. Right now i have 3.... the two mentioned above plus my OS one....this is apparently my limit and so when i go to format it, i'm not allowed to create a fourth partition for my 'Data' drive.
If i rebuild, i was planning to delete the current windows partition and the system_drv partition which would free up the two i need. I wanted to leave the recovery one there just incase i want to go back to factory settings.
The question...does the recovery partition rely on the system_drv partition one? Is there something I'm missing above?
Thanks in advance.
Solved!

Hello and welcome,
If you touch your partitioning in any way, you're likely to lose the ability to boot the recovery partition.  Burn a recovery media set before touching anything.   Then at least you'll have DVDs that can restore your system.
If you somehow maintain recovery partition bootability, that's a bonus.
My personal practice is to burn a factory media set, then  either scrub the entire drive or just delete the recovery partition add the freed space to C: - and take advantage of the drive's full capacity.
With most ThinkPads, if you double click (or right click?) on the recovery partition, it will offer to burn media, delete the partition, and add the space to C:.  You could do that, then resize C:, or just burn, delete, and create your data partition.

  • Create data partition and ubuntu partition

    I would like to create 2 more partitions on a ThinkPad x230t tablet: one partition for all my files and other partition to install ubuntu OS.
    According to Disk Management the computer already has the following partitions:
    SYSTEM_DRV              Simple, Basic, NTFS, Healthy(System, Active, Primary Partition)
    Windows7_OS(C        Simple, Basic, NTFS, Healthy(Boot, Page File, Crash Dump, Primary Partition)
    Lenovo_Recovery(Q   Simple, Basic, NTFS, Healthy(Primary Partition)
    I have read that there is a limit to the number of primary partitions allowed and that partition type and placement matter.
    Any suggestions on how to proceed are welcome.
    Thanks.

     - As I read, I guess GRUB makes the recovery button useless? I don't want to lose my licensed Vista, so what can you suggest me to do?
     I think it will work. At least if it doesn't you may reinstall Rescue and Recovery.
    After shrinking C: drive, it complains about not being able to find winload.exe and does not open
    You have to recover the loader. I used a Windows Vista bootable DVD for this purpose.

  • Can I use One Hard Drive for 2x Time Machine Back Ups and another partition for all my data?

    Time Machine back up for 2nd Mac
    Anothe partition for all my data.
    then have that RAID'd to second disc?

    That is indeed unfortunate. You will need to order a recovery disk set from HP or an HP Partnet. Here is how to order a recovery disk set.

  • Problems with Boot Camp and Drive Partition

    First of all, let me preface this by saying I have in the past successfully partitioned my drive and installed Windows, but it was a while back and I can remember it was frustrating, but I don't remember the exact details. Also, I apologize for the rambling nature of this problem, but I'm trying to give as much relevant information as possible and walk through the steps I took to get where I am now.
    Feel free to skip ahead to the end, the main problem seems to be I tried to create a 300 GB partition, but it didn't take or something. Now my storage is reflecting I've lost 300 GB, but it won't recognize the existence of the new partition.
    Let me just walk through what I did. I deleted my previous partition because I was having some difficulties with a few programs and the partition ended up being too small and I wanted to make a bigger one anyway. I only use it for gaming and didn't care about any of the saved games so I just deleted the partition and figured I'd start over from scratch.
    Before I begin, some technical details about the computer I'm working with. I don't know how much of this is necessary, but here it is:
    It's a 27-inch late 2012 iMac with a 3.4 GHz Intel Core i7 processor with 24GB RAM running OSX 10.9.4
    The storage space is a little more difficult as that is part of the problem I'm running into, which I'll get to in a minute.
    Anyway, I have a Windows 7 Professional install DVD and a burned CD called Boot Camp, which I think is the drivers from last time I installed Windows (a year and half ago?), but since I needed Superdrive for the install DVD I just used an XHD I had to put the drivers on (like I said, I don't remember how I did it last time). I go through Boot Camp and look at how much space I have and how big I want to make my partition.
    Side note: Last time I made my partition, I'm fairly certain I set it to 200 GB, but the partition size actually came out to something like 112 GB or something significantly less. I didn't know what happened, but figured it would still be enough space and it had been such a hassle I didn't bother doing it again.
    Supposedly I have a 1 TB HD, and I can't remember exactly what it said when I partitioned the drive this time, but it definitely said I was using less than half of my capacity and I had plenty of room, so I opted to go for a 301 GB partition (the slider wouldn't let me do exactly 300) which still left me with around 300 GB of space left over on my Mac partition I want to say. I went ahead with it and it started partitioning the drive with the blue line moving very slowly and after an hour or so it was like 80% across but no longer making progress. I looked online and people said that shouldn't happen. I cancelled the partition and the Disk Utility showed the partition, but said it was unmounted or something.
    I restarted my computer thinking maybe I'd try and see what would happen if I tried to boot it up as if I had Windows installed. I also at that moment remembered that I'd had a similar problem last time because I had my XHD plugged into my USB port so I unplugged that and held down OPT. It then showed me my Mac HD drive and a CD icon that said Windows, so I clicked on that figuring maybe I could install it after all.
    It led me through a Install manager and it got to the point where it asked what drive/partition do you want to install Windows in, I recognized the screen and remembered I was supposed to choose a certain one, but couldn't remember which one and none of the sizes seemed to match the storage I had allocated to the partition. One was about 200 GB and since the last time I did it my partition came out 100 GB smaller than I had set it for I thought maybe that was it.
    However, it said I couldn't install on that drive for some reason (I can't remember exactly what it said). So I restarted again and figured I'd go back and see what I did wrong and start over. When I check Disk Utility it no longer sees any partition (mounted or unmounted or anything) and that the entirety of my HD is dedicated to Mac HD.
    The problem is, now I'm getting weird reports about the size of my drive, the amount used, and the space available. Disk Utility tells me I have 1.12 TB capacity, 301 GB available, and 819 GB used. That doesn't even add up. Furthermore, when I click get info on Macintosh HD, it tells me I have 810 GB capacity, 364 GB available, and 446 GB used. When I click on About this Mac and go to System Report and storage I get this:
    Macintosh HD
    Available: 364 GB
    Capacity: 810 GB
    Logical Volume Group:
         Name: Macintosh HD
         Size: 1.12 TB
         Freespace: 301 GB
    Physical Volumes:
         disk0s2:
         size: 121 GB
         disk1s2:
         size: 999 GB
    Now I really don't know what to make of it. That 301 GB free space makes sense as the partition I tried to create and if I add that to the 446 GB used on my Mac partition, plus the 364 GB available, that adds up to 1.12 TB (roughly, I've rounded off these numbers).
    But how come Disk Utility doesn't recognize the partition then? What should I do from here?
    I couldn't find anyone asking this exact type of question or running into this same problem before, so I hope I'm not asking about something that's already been answered. If that's the case, if you could direct me to where I can find the answer I'd be appreciative.
    Otherwise, any help or light that can be shed would be most appreciated.
    Thanks!

    The problem seems to have gone away. I did click on repair disk in Disk Utility, I'm not sure if that did anything, but now when I run Boot Camp Assistant it is showing me the correct free space, so I don't know what happened. Oh well.
    Still having trouble getting the **** thing to partition, but that topic is covered extensively elsewhere.

  • HT4818 I want to have an exFAT parition in addition to the Mac OS X and Windows partition.  If I create it before running BootCamp, it wants me to delete it.  If I create it in either Windows or Mac OS X afterwards, I can no longer dual boot.

    I want to have an exFAT parition in addition to the Mac OS X and Windows partition.  If I create it before running BootCamp, BootCamp wants me to delete it before continuing.  If I create it in either Windows or Mac OS X after running BootCamp and installing both OSes, I can no longer dual boot.  What is the magic sequence to get this to work?

    I've got the same quandary.
    After upgrading my hard drive to a Momentus XT Hybrid and doing a clean install of Mountain Lion, I was surprised that I couldn't format partitions separately and then restore from my clone of the old Windows 7 Partition. I found that I had to use the BootCamp Assistant to manage it all, which essentially meant getting rid of the partitions and starting again...   
    I now can't get my Windows / BootCamp partition to boot, after adding a 3rd, ExFat, partition, when it was working perfectly fine before. I just get a lot of dos booting failures and a final message that "No boot device is available, press Enter to continue".  
    See the attached message, that I get when trying to boot the bootcamp partition, through Parallels 7; which also worked perfectly fine before.
    Be good to know if there is a work around this in Mountain Lion as, if not, I'm thinking I might skip Bootcamp altogether and just install a machine drive via Parallels. As suggested here:
    http://forums.macrumors.com/showthread.php?t=1420754
    I might even keep the virtual windows machine on a separate hard drive and then I'll have no need for the ExFat partitions altogether as that was designated for  sharing between Windows  and Mac.

  • RE: NT Server Reboot and Forte Partitions[Ref:C943460]

    Hi Bradley.
    At our customers, we need one of our Forte applications to be running for data
    communications to take place. After a reboot, we need this application's
    partitions to come online. The way we did this (as you suggested) was to use a
    BAT file, and then install this as an NT service (we used a utility that comes
    with the NT resource kit - srvany).
    This works fine for us. One of the issues we had was that the partitions tried
    to come online before Oracle was running - this resulted in the dbsessions
    failing and the partitions not coming online. We got round this by preceding
    starting the partitions with a loop that polled Oracle until it was up. Needless
    to say, piping all output to log files was essential for us to figure out what
    was going on.
    Hope this helps,

    Subject: NT Server Reboot and Forte Partitions [Ref:C943460]
    I have a system administration question for users with NT servers in
    their Forte environment. If I have installed Forte partitions on an NT
    server which I would like to startup when the server is rebooted, then
    what are my options for scripting this to happen automatically?
    Currently the only Forte process on the server which starts up
    automatically is the Forte node manager, through the installed NT
    service. I have been contemplating setting up a BAT file process as an
    NT service which would wait for the Forte node manager service to start,
    and then execute an fscript file to start the required forte partitions.
    How is this situation being handled in other environments? Thanks.

    Hi Brad,
    I am not sure if this is the right solution in the long run, but if you
    login into NT after reebot you can create a simple client that "pings" your
    service objects and put the shortcut into the Startup Group. I think such a
    client may also be useful to monitor your Forte server for application
    specific parameters, instead of relying only on logs/econsole.

  • Dual booting /w mac mini and shared partition

    I bought a mac mini a few months ago, I wanted to replace an old macbook which died.
    It had osx 10.4 on it, probably a beta or early bootcamp. I had a tri-boot system with
    a "shared partition", but when I've tried on my mini I get into problems.
    I'd like to have at least a windows 7, and osx partition and a larger, shared partition on same drive.
    On my last attempt I left the drive as single osx. Let boot camp partition it, booted to cd, installed..
    After installing, and updating, windows I partitioned the drive for the "shared partition" and rebooted.
    I could reboot into windows but osx would hang while booting. I had to download and re-install the system.
    BTW I am using a usb cd/dvd-rw drive to boot into my windows cd
    Can someone help me figure out what I did wrong or provide a howto, guide or link to get me through this?
    Thanks for visiting

    What year/model Mac mini, new, used? What Mac OS are you using?
    Pre 10.7 you could add two OS's and an extra partition without too much problem (running rEFIt, BootLoader, etc) but 10.7 added a wrinkle to that.
    With Lion and any other OS (10.7 and Windows, etc.) you actually already have a "triple boot" system with the invisible "Repair Partition" added and Apple doesn't support any more.
    Here's an older post but basically the same answer except with Lion and W7 adding an exception to the rule.
    People have added more partitions but you would have to do a search here or do a Yahoo/Google to find the directions for doing it on one HD.
    (I've only used rEFIt and it worked fine for me, not doing it on one HD, I have a MacPro so it's easier to just use another HD)
    Other options,
    You can always install the Mac OS on an external HD or even have the external as your Data drive or depending on how large or how many files you want to transfer there's also the Thumb drives.
    And there's also Parallels/VMWare that you can use to transfer stuff until you need to boot into Windows natively.

    Probably this one in white color instead of silver. Right?
    Satellite L755-S9530D  (PSK2YU-08X023)
    what should i do to get the recovery partition back? ... get back all the HDD space on one partition C the way i bought it
    Restore the hard disk to its original out-of-the-box contents using the Toshiba recovery discs.
    Before doing that, back up the data drives.
    If you insist on creating an additional partition, shrink the C partition and put it in the space created. Best to use a third-party tool.

  • Sharing the /home partition and general partition questions

    Hello, I'm new to Arch, but have been using Linux for a few years (albeit still at a beginner level).  I'm going to be reinstalling Arch on an old computer that has a 40GB main drive so dual boot a "operational" OS for day to day stuff that I want to make sure will be running well and then another OS that I can test on or just have for trying new distros.  I also have an 80GB that I'll use for data (but I don't think I want that to be my home drive). 
    My question is:  If I have two different installations of Arch, (or a second distribution) should they share the same /home partition?  My thought is "no", but I didn't know.
    Also, I'm planning on splitting the 40GB drive the following partitions.  Do these make sense, or would there be a better way to do this? 
    5GB = / (OS #1)
    14.5GB = /home (OS #1)
    5GB = / (OS #2)
    14.5GB = /home (OS #2)
    1 GB = swap (both OSes)
    I have an ancient P4 w/ 512 of RAM.

    sharing /home drives would NOT be a good option in your case simply because you are going to use the 2nd OS as test/trials. Those other OSes may have different ways of storing config files etc which may lead to having a lot of junk to parse through. and if you ever use any configs for the Test OS, and they are somewhat in conflict with Arch - in any way - you might end up having to re-configure settings for your favorite apps in Arch.
    I have a 30 GB HDD on a 10 yr old laptop which has Arch. This is the partition scheme I have

    Since you have 10GB more than I do, you can adjust accordingly and make partitions for your test OSes as well.

  • Screwed up MBR and boot partition, can't fix it [SOLVED]

    Hi,
    I have been defeated. Been trying to fix my computer the whole day and know I'm lost.
    It's a long story, but my whole system got screwed when I tried installing windows on top of arch (I didn't get it to install, but I don't care anymore).
    I was able to install GRUB2, I tried configuring it with grub.cfg , but when trying to boot it says it's missing kernel, boot partition has linux2.6, and I was using linux 3, I'm not really sure how to get the kernel I was using, should it be in my root partition? .
    I'd like to get my system as it was before, I have root , var and home partitions and not sure how.
    Thanks

    Thanks for your reply.
    I was using Arch, I last updated a few days ago.
    The kernel that's on the boot partition is from a debian live cd I had laying around.
    It is not possible I have more than one boot partition. I have 1 hard drive, but plenty of free space.
    Windows wanted to use the start of my disk, so I used gparted to move 20 gb free space at the beginning. Creating a partition in the beginning also caused all partitions numbers to move up (sda2->sda3), when I gave up on windows, I tried moving everything forward like it was before, but it didn't work. Then I remembered that when installing grub, installers check for other mount points, but that didn't work, and instead overwrote my boot partition. So know I've got a temporary debian system installed(sda9) and a boot partition that won't boot Arch.
    This is my fdisk output: sda5 is arch sd6 var and sd7 home

  • Recovery CD - clean install and new partitions or install over old OS?

    I have a T400s running Windows 7. While using the factory recovery tool, the restore was interrupted. The OS wouldn't boot and the F11 function was disabled.
    I ordered the recovery CDs, which will arive today. Now, there are 3 partitions on my ThinkPad: a boot partition, the OS partition, and the recovery CD partition. My question is this. Will the Recovery CD do a clean install ... wiping all 3 partitions and reinstalling the entire OS and recovery partitions to the factory state? Or will it simply reinstall the OS in the OS partition, leaving everything else alone? Thanks.
    P

    Since you'll have the Recovery Media, you could elect to simply remove the recovery partition.  This can be done through Disk Management (right-click Computer in Start Menu and choose Manage).  The drive should be set up with the Service Partition, the C: partition, and then the Q: partition.  If you delete the Q: partition you can then extend the C: partition.

  • Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition

    just bough OSX Mountain Lion, my laptop operating with v10.6.8.  Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition table. 24.44gb disk available.

    Verify your computer can run Mountain Lion:
    Upgrading to Mountain Lion
    To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
         OS X Mountain Lion - System Requirements
           Macs that can be upgraded to OS X Mountain Lion
             1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
             2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
             3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
             4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
             5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
             6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
             7. Xserve (Early 2009) - Model Identifier 3,1 or later
    To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
    Open Disk Utility and verify the drive is partitioned using GUID and formatted Mac OS Extended, Journaled. If it is then do this:
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Now try installing Mountain Lion.
