I have a lap top HP pavilion dv6. The Windows 7 partition is of 443 GB, and I have 120 GB of free space there. I want to reduce the size of that partition so I can create a new partition of 60GB for Ubuntu. I used the Disk Manager in Windows, but it says that I can only reduce that partition by 1GB, and obviosly I can't install ubuntu in a partition of that size. I already defragmented my Hard Drive, but it only gave me 500MB of aditional space. I have installed Ubuntu with wubi in this laptop, but I would like a permanent solution, without losing windows.
Here's how I fixed that problem:
Start Windows and search for disk partitioning tool (installed by default). Let it calculate and shrink the partition, then boot up the Ubuntu installation and a new option will be available to install it alongside Windows.
Hope that helps
