    Re: Ubuntu dual boot HDD partition problem

    It is when you try to create more than 4 primary partitions with Windows. It uses dynamic not the extended partition with an unlimited number of logical partitions.

    Some other tools.
    Microsofts offical policy is a full backup, erase dynamic partitions and create new basic partitions. There is no undo.
    Dynamic volume is a Microsoft proprietary format developed together with Veritas (now acquired by Symantec) for logical volumes.
    You may be use a third-party tool, such as Partition Wizard MiniTool or EASEUS to convert a convert a dynamic disk to a basic disk without having to delete or format them.
    I've never used any of these and so I can't be sure they will work.Be sure to have good backups as any major partition change has risks.
    Dynamic also on gpt as LDM

    EASEUS Partition Master - The free home edition converted both dynamic partitions into basic partitions in less than 5 minutes!!

    Several users have used this, it has a liveCD download to use but you have to use the non-free version:
    MiniTool Partition Wizard Professional Edition 5.2 to convert without loss of data the disk from dynamic disk to a basic disk.
    also used Partition Wizard to set an existing partition logical instead of primary

    Hi Weedoobs,

    I also went through the same problem as urs while dual booting. Here are the steps I followed to make it work.

    1. Take all the data backup in external HDD or DVD or any other media because you have to delete all the drive to convert it from dynamic to basic.
    2. Now boot the dive with the windows boot-able CD and delete all the partition and make only 4 partition (if you make more windows will convert all the partition into dynamic as before). Two partition for Windows (System Boot & Windows C Drive), One for the other files to be stored in your computer and last one for the Ubuntu partition.
    3. Install Window first as you do before. After you have finished installing the Windows now boot from the Ubuntu CD or Bootable pendrive.
    4. Install the Ubuntu in the Last partition (as you cannot make more than 4 partition).




    I think this will work out for you for the dual booting the PC.



    If you come across any problem regarding boot as I have encountered while booting (after installing ubuntu the PC directly boot from Ubntun without giving the option for the user) do search for the Boot- Repair and follow the instructions. I have also given the link of it below if you need it.

    Most desktop installs do not need /boot. But Linux works just fine from logical partitions. You create logical partitions in one of the primary partitions that becomes an extended partition. Windows is the one that only works from primary partitions.

    Be sure to create recovery DVD(s) first. And a Windows repair CD.

    You need that but its an option (you can make it or not its your choice). But in this case of dual boot you should not create one as you have mentioned. Do install the Ubuntu as I have mentioned in my previous post, it will help you.
