    Unable to delete old partition


    Hi,
    To install windows 7 I used unallocated space at the beginning of my hard disk (it was previously used for an installation of Ubuntu Linux which i stopped using). Now I wish to delete the old Vista partition. The delete volume... option in Disk Management was grayed out so I trued using DiskPart. Here is the commands I used.

    =====#=====

    C:\Users\Jake>diskpart

    Microsoft DiskPart version 6.1.7100
    Copyright <C> 1999-2008 Microsoft Corporation
    On computer: ######

    DISKPART> select disk 0

    Disk 0 is now the selected disk.

    DISKPART> select partition 2

    Partition 2 is now the selected partition.

    DISKPART> delete partition override

    Virtual Disk Service error:
    Delete is not allowed on the current boot, system, pagefile,
    crashdump or hibernation volume.

    =====#=====

    What did I do wrong? That partition is not in the MBR (I have checked using bcdedit and the GUI under setup and recovery options. The pagefile is on C: (The Vista volume was labeled as D and then I unmounted it). Crashdump is %SystemRoot%\MEMORY.DMP. Not sure what the hibernation volume is but...

    Is using GParted Live safe (I know that you generally can't modify NTFS without getting a stop error for the NTFS.sys file). But can you simply DELETE one without the .sys becoming corrupt?

    Any input would be great.
    Thanks

    Solve it by making the Windows partition "active" and make sure the boot manager, pagefile, hibernation file, etc. resides on that same partition. Then you can format the old partition all you want.

    It's handy to have some extra tools in your arsenal. I often use something like Acronis Disk Director (on a bootable thumb drive) and VistaBootPro. Keep in mind that the Windows 7 DVD itself also has some startup (boot manager) repair tools.

    OK It's marked as Active but the Old partition still has the "System" Flag. How do I change this?

    Thanks

    by moving or installing the boot manager to the Windows 7 partition.

    btw if you don't want to use something like EasyBCD or VistaBootPro, apparently you can do it by command line. See Moving Boot manager to Different Drive

    Hi Broken 32,

    Just to expand on sup3rsprt post.

    It is not to do with the MBR.

    The problem is that the Vista partition is the "System " partition - it contains files needed to boot into 7.

    If you want to delete the Vista partition , you can Make the 7 partition the system one like this:

    1. Go to folder options and make sure hidden files and Protected operating sytem files are showing.

    2. Copy and paste bootmgr and the pale yellow Boot folder from Vista partition to 7 partition. ( You will get a message bcd is in use and can't be copied - skip it and copy the rest)

    3. Open an elevated command prompt ( type cmd in start search - when it pops up, rt click and run as admin. )

    At the prompt >, type:

    bcdedit /export C:\Boot\bcd

    It will look like this:

    Microsoft Windows [Version 6.1.7100]
    Copyright (c) 2009 Microsoft Corporation. All rights reserved.

    C:\Windows\System32>bcdedit /export C:\Boot\bcd

    press enter , close cmd prompt.

    4. Go to Disk Management and rt click 7 partition - select Mark as Active.

    5. Restart.

    7 is now the "System" partition - don't worry about the auxiliary o/s files - they were created on restart.

    Hope it helps.

    Hi,

    Thanks both for the help

    All that was needed was to change the "Active" flag over to the Win7 Part. Then I ran a recovery, which resulted back in a dual boot, then deleted the Vista partition. Now it works.

    Interesting, I am going to try that.

    I will delete bootmgr and Boot folder from 7 partition and see if startup repair can replace them.

    Hi Broken,

    Thank you for reminding me to try that.

    I had looked in the .wim for the 7 WINRE and found it contains bootsect.exe.

    This is significant because it is not on the Vista recovery disc - tho. it is on the Vista dvd and bootsect commands can be performed from that in Winre.

    I had meant to try the recovery options to see if they would be automated in 7 Winre - but had not got round to it.

    I just tried it and indeed they are.

    It took two runs - it seems the first creates the Boot folder on the Active partition, and the second creates bootmgr.

    It also works on Vista.

    I am pretty much in the same boat, but did some dumb things before reading this post. Here is a conversation I had with my tech friend.

    i'm getting punished right now, you ever have a dual boot and once your new o/s was good to go you then wanted to get rid (format) of the old os but couldn't. I imagine if both weren't on the same disk i wouldn't be having this problem. found a pretty good page on the subject though
    Lude says
    ya not sure how that works
    Jigady Jenx says
    its devasting
    pretty sure i just frakked his comp to, i just restarted it and it won't come back online
    Lude says
    whos
    Jigady Jenx says
    grandfather's
    Jigady Jenx says
    8 minutes down
    hes gonna be soo pissed lol
    Lude says
    u have both on logmein?
    Jigady Jenx says
    yah but that vista is in no shape to actually boot up again
    i did a retard move while i was there and just tried to delete everything off it to see if whatever was stopping disk management from formating it would disappear
    after i deleted all i could it didn't help but it would still reset fine
    apparently dual boot the 2nd o/s uses shiz off the first one to boot, which makes no sense to me.
    so when i set vista to unactive that probably stopped it both from booting
    Lude says
    prolly
    Jigady Jenx says
    lol
    Lude says
    dual boot is gz
    Jigady Jenx says
    its kind of like a car and starter, active booting or w/e is the starter once the car/comp is running you can remove the starter/boot and it will still run, but one you turn engine/comp off it won't start up again
    kinda neat

    Lude says
    ur a big neat guyyyyyyyyyy
    Jigady Jenx says
    Yah I'm assuming next step will be to pop in win7 disk boot off it and repair 7 which will then add the boot stuff needed and i will be able to format the vista partition. I'm sure it won't go that way.

    Whats my next move?
