Bootcamp - Create new partition and format in Windows 7

Hello All
I have Windows 7 installed on my sons MacBook Pro.
The Drive is partitioned at 500GB for Windows and 300GB for Mac.
In windows, I need to shrink the Windows drive, and then create 2 extra drives from it.
However, I can shrink the drive, but when I try to Format, it tells me that it cannot find the drive, and then it changes the drive types to all "Dynamic" including the Mac Drive.
And once this happens, I can no longer access the Mac drive during Boot, and windows will not load, as it cannot find the drive during windows boot up. And which point, I have to restore the system and it takes up to 6 hours to installed Lion, as my Internet is slowing that a cold winters day.
So, my question is the following.
How can I successfully shrink the drive.
Then Partition the FREE space
Then Format to NTFS without loosing drive type and integrity?
Thanks All

I ask because what you want to do can be done right from within Windows if you're creating two more NTFS partitions out of the original.
In a single disk system, the MBR looks like this. Even Windows cannot add an entry, unless this Hybrid MBR is manipulated by hand prior to the partition creation. For example, one can create the '0xEE' entry as start=1, size=1454211071, which then allows Windows to create two more entries. If that is done by hand, the GPT and MBR are now out-of-sync. which means OS upgrades or anything done in Disk Utility will cause a data loss or create Windows boot issues.

If the OP really wants a clean installation, pure EFI of both OSX and Windows is the best solution.

  • Few questions about partitioning and formatting in Windows 8

    Hello,
    I'm very shortly after a Windows 8 reinstall and I want to make use of this moment to finally understand partitioning and formatting in Windows 8.
    Before using Windows 8, I was an XP user for 5 years and I actually never bothered myself with formatting my main system partition, that's probably why my computer ended up working like a slime for the last years. Anyway, by now I have been using Windows 8 for a year.
    Three weeks ago I faced a system-related problem with my laptop (IdeaPad Y580) which prevented it from peacefully shutting down. A good friend of mine (XP user for his entire life, and now Windows 7 newbie user) told me, that I should keep all my non-system stuff on separate partition and that I should do the main system partition format from time to time to keep my PC out of trouble. It is sure that he took his knowledge from using XP, and here's my first question - does this method apply to Windows 8?
    I mean as far as I know, back then, in XP, partitioning was possible only during Windows installation, and now, in Windows 8 we have a Disk Management for this, which do not require running Windows installation to create new partitions.
    I'm mentioning this due to the fact that originally (I mean by factory settings) my drive has only one visible partition - C: (1TB), so I would need to use the Disk Management to take some space from C: partition and allocate it to the new D: partition.
    In case I do this whole partitioning operation and create a D: partition, is it sure that formatting my system-only C: partition won't have effects on my D: partition, and all the programms and data I have here will stay on their places and work after format? (I'm worried about this because I've seen in some partitioning guide a warning not to format the main partition after the partitioning operation, because it would erase totally all data - I'm not sure if I misunderstood something or is it a mistake? EDIT: here's the link for this guide, just jump to the "Final Thoughts" section to see what I'm taking about: http://www.technorms.com/8438/windows-8-create-hard-drive-partition ).
    If this whole method of keeping your system running fine doesn't apply to Windows 8, I guess I'm okay with having only one C: partition.
    By the way, it doesn't matter for me if I create new partition in terms of conflicts with preinstalled Lenovo OneKey Recovery, since I had to reinstall my Windows 8 recently from non-Lenovo CD, and either way my laptop is now totally clean, without Lenovo stuff (I found Lenovo Recovery CD for Y580 on the internet, but it had non-single-language Windows 8 in it, and I needed a single-laguage one in order to have my Product Key recognised, so I just used a pure Windows 8 SL installer)

    I just found out that I can't even transfer my Users folder or Program Data to other drive than the one with the system, because it would prevent me from updating my system or even from actually booting to my system. So apparently my whole topic is for nothing... I guess I should live with only one drive, and whenever my system totally crashes again I should do the backups to my external HDD. It's sad though that Windows 8 is a total opposite to user-friendly OS, to say the least.

  • Can I force the bootcamp wizard to skip looking for the bootcamp drivers?  I have already downloaded the latest drivers and loaded them on a FAT usb drive.  All I want is for bootcamp to create the partition and allow me to install windows 8 pro

    Hi Everyone,
    Can I force the bootcamp wizard to skip looking for the bootcamp drivers?  I have already downloaded the latest drivers and loaded them on a FAT usb drive.  All I want is for bootcamp to create the partition and allow me to install windows 8 pro.
    The bootcamp drivers have been downloaded from apple's website.  Filename:  BootCamp5.0.5033
    I have a iMac 27" late 2013 model.
    NOTE:  I have downloaded the drivers manually from apples support site as the bootcamp wizard fails third of the way through the download.
    Appreciate any assistance.
    Regards,
    asdutoit

    There is a missing point in this thread, and it is that the Boot Camp drivers for the Late 2013 iMac can only be downloaded from Boot Camp Assistant. The Boot Camp drivers available in the Apple site are not compatible with that iMac.
    Delete the Boot Camp drivers from the USB drive, open Boot Camp Assistant and try to download the Boot Camp drivers again. If you get a message telling you that they could not be downloaded, I would try reinstalling OS X through OS X Recovery, by holding down Command and R keys while your Mac is starting up

  • BootCamp cannot create new partition on drive free space.

    Hi Folks,
    I am hoping for some advice here. I am running OS X (10.5.6) and wish to use Boot Camp to created a partition to install Windows XP SP2 for some gaming. My machine is a late 2007 MBP 2.4GHz C2D, 4GB RAM, 340GB WD transplanted hard drive.
    I have about 180GB of free space for a new partition to be created for the XP install.
    When I fire up the Boot Camp Assistant tool, I am immediately informed of the following:
    "The startup disk cannot be partitioned or restored to a single partition."
    "Back up the disk and use the Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using the Boot Camp Assistant again."
    + I have never had more than one partition on this drive.
    + I installed the drive new with no partition and used a tool named 'Carbon Copy Cloner' to transfer data from the original drive onto this drive, the machine booted right away and I have been using it without issue ever since.
    + I have run Disk Utility to 'Verify Disk', 'Verify Disk Permissions' and 'Repair Disk Permissions' all ran with no problems and completed successfully.
    My question is, how can I make a usable backup copy of the drive to restore back to the drive after performing the re-format?
    Can I use the Carbon Copy Cloner software for this? I want to make sure that the resulting internal drive is bootable, etc.
    I have been running Time Machine as well and have a disk full of backups from that app, but I have no idea how to use it to restore the drive to it's current state after re-partition and format.
    Thanks in advance for any and all suggestions.
    John

    So today I used the free "trial" version of SuperDuper to create a bootable clone of my primary internal drive.
    It was about 100GB and took a long time to copy onto USB 2.0 external SATA drive, but it worked.
    SuperDuper provided the option to make the copy the boot device as well. After reboot, I used OS X Disk Utility to erase primary drive.
    I then performed the operation in reverse, copying the entire contents back to the original location.
    After a reboot, I ran the Boot Camp Utility and received the same aggravating message which I received before.
    How can I be sure that I am actually re-formatting the target drive in order to consolidate free space? Is this my issue? When I performed the erase operation, I skipped the "zero out free space" step. Am I using the correct utility to prepare the target drive?
    Once again, any and all help is greatly appreciated.
    Regards,
    John

  • Need help to partition and format new hard drive for T400

    The HDD failed in my T400. I bought a new 1TB HDD and fitted it. The diagnostic software in the BIOS did a read and controller test (Passed). When I put the Windows XP disk in the CD reader, the setup started - then stalled at the "Windows setup" page. I thought the hard drive had a write problem but apparently it must be partitioned and formatted first, before Widows setup can commence. The thing is that I can't get to the option where Windows formats the drive. In old computers, there was always a partitioning option in the BIOS setup but in my T400, there doesn't appear to be any such option. The computer has 4GB RAM, the actual model is 2767-RV8.
    Does anyone have any suggestions how to get this up and running?
    One other question is - (assuming I can get the thing working) - Is there somewhere I can load the operating system on part of the hard drive where it can act as a fall back in case the operating system gets corrupted? - i.e. something that can't get attacked by malicious software?
    Thanks in advance for any assistance.
    Ian

    Hi irivlin,
    If you are trying to clean install XP, then you have to do following setting in BIOS first:
    Press F1 to BIOS, Config -> Serial ATA (SATA) -> change to "Compatibility"
    You can change XP partition only if you are doing clean installation, otherwise you have to use 3rd party to do it.
    For backup part, there are lots of choices in the market. You might consider using XP own backup function. Lenovo got a program called Rescue and Recovery can also do backup as well.

  • Can I restore my mac from a Time Machine backup once I have used BootCamp to partition and set up Windows (without erasing all of the Windows content)?

    A few months ago I partitioned my mac using BootCamp and successfully installed Windows and a few Windows-only programs (games).  I never restored my mac from the Time Machine backup and now I would really like all of my files back on my mac.  I am wondering if I insert the osx install disc and restore from Time Machine backup, will that get rid of the partition I made for Windows?  Will the Windows side of my hard drive stay in tact or will everything on that side get erased when I restore the mac side from the Time Machine backup.  It was a HUUUUUUUGE pain to do the BootCamp partition and get everything Windows set up and I would really like to not have to do that all over again.  I just want to make sure that if I insert the mac osx install disc and restore from Time Machine backup it will only affect the Mac partition, NOT the Windows partition.

    Hi,
    Time Machine does not touch your BootCamp Windows.
    It simply said ignores it completely.
    Nonetheless, I am curious as to why you wanna restore a Time Machine backup.
    Usually during partitioning with the BootCamp Assistant in OSX to make the Windows partition your OSX stays intact.
    Regards

    Hello Kaj_R.
    If you change the volumes it is quite likely that the recovery partition will not function.  I suggest you create a set of Recovery Media before messing with the partitions.
    This document can help you create the recovery media.

  • Can't create new partition

    Hello.
    I have a problem. I want to install WinXP via BootCamp and can't create new partition for it.
    BootCamp Assistant crashes during partitioning (kernel panic), and when I use Leopard installation disk and try to create new partition in Disk Utility on DVD, it returns an error "No space left on device".
    I repaired my hard disk many times (all errors were repaired) and still no improvement.
    I don't want to format my disk to zero, because I don't use Time Machine and it would be really difficult to restore all the data.
    Thank you in advance.

    Use Disk Utility Restore to copy your internal drive to an external USB/FW drive. Then reformat.

  • Problem in Creating New partition in Pavilion dm4 1217TX

    I have a hp Pavilion dm4 1217TX model laptop. I want to partition the hard disk (640GB) to separate the OS to the data. I think this is a very basic safety feature that will save my data in case of Windows failure (which is a very common problem). I have already split the C Drive and the new condition of my hard drive is
    System           199 MB       Primary
    C                        70 GB       Primary
    Unallocated   494 GB       Logical
    Recovery           32 GB       Primary
    HP Tools        103  MB      Primary
    Now I can't create partition in the Unallocated space because of 4 Primary Partition it already has. Now what can I do ? I can't understand that why it comes with four Primary Partition and without any Extended partition.

    Hi, there, I have the same problem with you, because of the OEM of the laptop, they have partitioned our hard drive in advanced, however this partition is not logical. As we know, when we install Windows7, the system partition and system reserved partition are set as primary partition without doubt, but how could they make the HP tools and other partition as primary partitino too. I'm very unhappy with this. I don't know WHAT are they thinking about. Every one who has a bit comptuer knowloage knows the rules of createing new partitions in Windows.  In my situation, I could only copy the data on recovery to C drive, then delete it. and recreate logical partition, then copy it back. Hope this could also help you.

  • Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive

    Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
    drive so all data gone included the drive which was encrypted by bit lockers.
    For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first 
    http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
    where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
    my data then i format the drive D and again tried to recover data using above software after decryption still no result. 
    Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanks

    Hi ,
    I am afraid that we cannot get the data back if the drive has been formatted even if use the
    BitLocker Repair Tool.
    You’d better contact your local data recovery center to try to get data back.

  • Thunderbolt partitioned and formatted hard drive not recognized on USB2/3

    I have a MBA (mid 2012) and recently purchased a Seagate Desktop Thunderbolt Adapter (STAE129), a Seagate Backup Plus 4TB USB 3.0 external drive (STCA4000100), and Apple Thunderbolt cable. The 4TB hard drive can be separated from the USB 3.0 adapter and the drive placed on the Thunderbolt adapter. I created two partitions (3TB and 1 TB) on the 4TB drive while it was mounted on the Thunderbolt adapter and formatted them Mac OS Extended (Journaled) using partition map scheme GPT. Everything works as expected, the drive hits r/w speeds in the 180 MB/s range (using Blackmagic Disk Speed Test), and no issues at all transferring data to the 3TB partition and using the 1TB partition for TimeMachine.
    However, if I disconnect the hard drive from the Thunderbolt adapter and place it on the USB 3.0 adapter and connect it to my MBA, Mountain Lion says "The disk you inserted was not readable by this computer and gives me the options to Initialize, Ignore, or Eject. Going into Disk Utility app, the drive shows up without the partitions I created when the same drive was mounted to the Thunderbolt adapter (just shows disk1s1). In fact, the drive label (Disk Description) is different too and the Partition Map Scheme now shows MBR!
    To try work-arounds, I went ahead and repeated the partitioning and formatting steps with the drive attached via USB 3.0 and all works fine until I put the drive back on the Thunderbolt adapter where once again OSX reports that the disk is not readable. I've even tried a single partition with no luck. In short, the drive partitioned and formatted on Thunderbolt is unrecognized under USB and vice versa.
    Shouldn't the disk preparation and data be consistent across these different interfaces? I would think so. My biggest concern is that if I had a failure in the Thunderbolt setup (assuming the drive itself does not fail), then I can't access my data. This is not a very comfortable situation.
    I'm assuming I've overlooked a very basic detail. Appreciate any steer to solve this problem.
    Thanks,
    Rob

    Thanks for that, I recently ran into the same problem. I even chatted with Seagate tech support and they didn't know the answer.
    My situation is a bit different from you. I bought the 3 TB Thunderbolt version of the drive directly and then purchased a USB 3 adaptor seperately.  You see, I still own a 3 year old Macbook Pro that doesn't come with a Thunderbolt port. I was looking to upgade to a MacBook Air later.  I thought that I might as well buy the TB version now.
    In anycase, my old MacBook Pro won't see the drive when I use the USB3 adaptor. I get the same exact error message as you did. I can't really test it on Thunderbolt since I don't have one.  I'm going to go install the Thunderbolt drivers now and hopefully, it will recognize the drive afterwards.  I'll let you know what happens.
    BTW, I was thinking of reformatting the drive with NTFS so that I can use the drive on PCs. My mac has the NTFS drivers loaded so it's no problem. I hope this won't screw up the Thunderbolt connection later when I do get the Macbook Air?

  • How to create new partition on a brand-new Satellite P50T-A0EE?

    Hi,
    I bought a Toshiba, Satellite P50T-A0EE SLV laptop yesterday with installed Win 8, in Adelaide. First, I realised that only one C:/ partition is available and no additional partition is created for data and for some reason, already 150 GB is used on the C:/ by the factory installed software.
    Moreover, checking the disk management, it came up that four primary partitions exist.
    One is the C:/, two others are called Healthy (Recovery Partition), and one is the Healthy (EFI System Partition).
    As I read up about it, a fifth primary partition is questionable to create, maybe even not supported.
    When I just started to launch on C:/ the 'shrink volume' command, much less space was offered to use than it was displayed as free under file manager.
    Could someone help, please how to create a separate partition with a reasonable size (600 GB at least from the 1Tb) for data? I would not like to keep my data files on a same partition with windows.
    Thanks,
    Gerti

    Hi dude,
    Before you would start to modify the HDD partitions table, I recommend strongly to create an Toshiba Recovery Medium using the preinstall software/tool called Toshiba Recovery Media Creator.
    This software creates either the recovery disks (DVDs) or Recovery USB flash memory.
    Its very important to create such medium in case you would like to go back to the factory state.
    After that you could use an open source software like Gparted tool to create the partitions and to modify the HDD partitions table.
    http://gparted.org/liveusb.php
    Note: the partitions which are already available on the HDD contain the Toshiba recovery image which allows you to recover the notebook from HDD. But this is possible only in case the HDD partitions table has not been modified in the past.
