I had 4 partitions while using windows 7 (in addition to 100 MB hidden) 1 14 GB for Windows (too small , that's what started my problem) 2 48 GB for page file (I don't how they set this to page file but it had this "Page file" in desc.) 3 40 GB 4 819 GB I tried to partition my pc while installing win7 again (first time not me) and I couldn't change anything (I thought it works like winXP) I went into repair tools and command prompt I deleted # 1 & 3 (see above) and ended up with: _____________________________________________ Disk 0 Online 931 GB 63 GB (free) Dyn (*) Gpt ( ) ---------------------------------------------------- I tried using the commands: select disk 0 create partition primary but I got this as an answer: Microsoft Diskpart ver 6.1... Partition - Create partition Volume - Create volume Vdisk - Creates a virtual disk file. So my current volumes in Disk 0 are: Volume 0 H new volume NTFS Simple 819 GB Status (Healthy) Info ( ) Volume 1 E new volume NTFS Simple 48 GB Status (Healthy) Info ( ) Volume 2 F new volume NTFS Simple 100 MB Status (Healthy) Info ( ) Could anybody help me get out of this miss ? I need to make the unused 65 GB as a partition and load win7 on it. I have no clue about dynamic or basic (they were all dynamic I guess).... what command should come next ? Update: I deleted all partitions... When I go to windows installation, I see Disk 0 Unallocated space 931.5 GB and below is error in yellow: Windows cannot be installed to Disk 0 Partition 1 (see details) details: The partition contains one or more dynamic volumes that are not supported for installation ? How can I go now ?
