    Accidentally changed hard drive with OS to dynamic drive.startup fail.


    Hi. My laptop is Acer with Windows 7 home premium 64 bit OS.
    It contain only 1 single partition disk that is c drive only.
    Recently, i accidentally convert the c drive which contain OS into dynamic disk.
    After i restart the laptop, it shows the following:
    BootMgr is missing
    Please press Alt, Ctrl +del to restart
    Now, i not able to enter the window. I am so worry because my important data is kept inside the hard disk, and i still not yet do any back up copy on it.
    I searching on this forum and learnt that i need a window 7 installation disk to repair it, but my problem is the computer dealer not give me any windows 7 installation disk when i baught this laptop as their said all the driver and windows program already kept in side the harddisk.
    Any help are much appreciated...

    I tried to remove the laptop hardisk which is a 500GB toshiba SATA hardisk. Then, i use the other laptop with Windows XP professional with the intention to copy yhe file inside the toshiba hard disk.

    However, after plugged in the hard disk to the other laptop, under the disk management, it shows that the toshiba disk as : dynamic disk, unreadable.
    So, i having problem to backup the data inside the toshiba hard disk.....

    Hello Yee, welcome to Seven Forums!









    Have a look at Option Four in the tutorial at the link below to see if the "Set Partition as Primary" option is available; there's also a link in the same tutorial for the info on creating a Windows recovery disk.

    To convert a Dynamic Disk back to Basic is a destructive process.

    First try to copy your data out using Repair CD:
    Copy & Paste - in Windows Recovery Console
    System Repair Disc - Create

    If your computer came preinstalled with WIn7, it may have protection on the Recovery partition so you can still run it from boot to convert and reimage the HD. Try tapping the key given on first boot screen for Run Factory Recovery. Or look in your setup literature or Manual on the Support Downloads webpage for your computer model.

    Otherwise you will need to order Recovery Disks from manufacturer, or find any retail copy of Win7 to unlock all versions to reinstall your licensed version using the Product Key on COA sticker:
    Windows 7 Universal Installation Disc - Create
    Clean Install Windows 7

    Once you're ready to run Recovery Disks or Clean Reinstall Win7 from booted installer, boot the DVD or Repair CD, press Shift F10 to open a Command Line and type the commands given here to convert the Dynamic Disk back to Basic: http://technet.microsoft.com/en-us/l...15(WS.10).aspx
