I have HP Laptop with 640 GB hard disk with Windows 7 64 bit installed. I wanted to have dual boot with two versions of Windows 7 ( 64bit and 32 bit) I used the Disk Management and reduced the C drive partition size, then I used New Simple Volume command to create a new drive in the new Unallocated partition and assigned the new drive letter as G as the system already have D, E & F for the recovery and DVD drives. After assigning the maximum available space and all other parameters, the system gives an error (There is no enough space available on the Disks to complete this operation) Did I do any thing wrong?

Hi, After checking your issue, you already had four partitions, I suspect they are all primary partitions. Hard disks configured as basic disks are limited to 4 primary partitions or 3 primary partitions and 1 extended partition and multiple logical drives. So you can’t create 5th one. Please check it. There are two solutions for your reference. 1. You can use 3rd party tools to repartition the disk. 2. You may try to delete a less important partition created already and merge the space together to create a new partition with proper drive letter.
