How do you dual boot Windows 7 and Fedora 20? Some information about my system: I am running Windows 7 Home Premium 64-bit on a HP Pavilion DV6-6135dx notebook computer. Windows was preinstalled by the OEM. There is a C volume, Recovery volume, and HP Tools volume. I shrunk my C volume using Windows Disk Management to make room for Fedora. So there are 90 gigabytes of unallocated space as well. The disk that these volumes (and the unallocated space) are on is a dynamic disk.

When I am using the Fedora installer (an iso on a flash drive), it does not recognize the 90gb of unallocated space. That's the problem I run into. It only sees 1mb of free space. It sees my hard drive as (almost completely) full.

So, what should I do? Any tips or advice?

Are you at the point where you're choosing the disk or the partitions? Also, I think that the space that was claimed unallocated by the Windows should be 'Empty'.

I'm inferring from the tags you used that the system is using LDM ( ) volumes with dynamic disks. LDM is like a container for other partitions; it is used to get limits on the total number of partitions, more flexibly manage storage, and combine multiple physical volumes to make virtual block devices. Linux has similar features with LVM, or Logical Volume Manager.

What you've done is to reduce the size of a partition within the container, to make room for another partition in the container. The size of that LDM container has not changed, but the contents have been rearranged. Because all of that space is still assigned to the LDM volume, it is not considered unallocated. Fedora cannot boot from LDM, and to the best of my knowledge, can not deal with filesystems inside it at all.

Your best option would be to research ways of resizing the LDM container using Windows tools. Fedora doesn't have tools for the task, and I believe any support in any distro would be considered experimental and quite risky.

You can confirm your partion layout with parted print /dev/sda or fdisk -l /dev/sda. Edit your question to include the results if you have questions.

Windows 7 comes with 4 primary partitions SYSTEM C: RECOVERY and HP-tools You must delete HP-tools using windows disk management then Deleting HP-tools doesnot couse any problem.I deleted it 3 years ego and done bios update without any problem. maximum number of primary partition is 4 on a disk.

Very useful info there, randomuser, thanks for the help. I found additional info in the fedora docs, which I will include in my answer below. And thanks for the tips, oldrifle. I ended up reinstalling Windows, dumping the OEM installation altogether.

What I found out was that the Fedora installer did not see the free space. While my Windows installation saw this as free space, it was really still allocated to Windows. I found some insightful information in the Fedora docs So I ended up reinstalling Windows, making sure to leave unallocated space during the partitioning step.

When partitioned a volume usually there is a small unallocated space at end. I have a DV7 and have 103MB unallocated space at end after RECOVERY.Anaconda see that in your case. Pls try my suggetion at comment.Pls also remember you can have only 1 primary partition even after deleting HP-Tools.
