    Deleting unnecessary partitions

    So after some bad times the other week I have reinstalled windows. I now have some (probably ) unnecessary partitions.
    I really should have wiped the drive and started from scratch when I reinstalled Windows but hey ho.
    Which of these are safe to delete ? Presumably I will need to keep EFI system partition but which of the OEM ones can I get rid of?

    Help, I deleted a partition, and can't seem to "extend" the other partition

    Ok, here's how it happened.

    I had 2 partition. XP and Win7 x86.

    I shrank the Win7 x86 partition and created a new partition (Win7 X64)

    I then deleted Win7 x86 partition.


    edit: what warup suggested did the trick. It took 20+ minutes for that software to do it, but hey it worked.. Thanks

    How to recover files off a HDD from a deleted partition? help!!!

    Thanks for your reply. I used my m8s program and it worked like a dream, recovered all the files and also deleted ones from yrs back, was amazed how well it did. Next step is i will use that Partition Table Doctor to recover the deleted partition. Thanks for the link *Toast :toast:

    Deleting unnecessary partitions

    W7 Hard drive partition issue

    to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

    - press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
    - diskpart <-- start the windows command line partition management tool
    - list disk <--- list the installed hdds in this computer for the next step
    - select disk 0 <- might have to replace 0 with the number of the correct disk
    - clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
    - create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
    - exit, exit to exit diskpart and the command prompt
    - click refresh in partition manager and select your newly created partition and install to that

    The OEM Partition is your recovery partition. This is where the PC manufacturer has stored the Windows image. So it is wise not to to delete this partition as it is important if you want to return your PC back to factory conditions or when your windows crashes in future and needs to be restored.
    But if you really want to delete it, you can try a third-party tool -AOMEI Partition Assistant since you cannot delete such partition via disk management.
