Windows 7 Ultimate 64 Bit - Installation Problems

You still have 212 gb going unused in the partition on the far right. To be able to use it rightclick on it in Disk Management or Partition Wizard to assign a drive letter.

You can also easily distribute that space to/from any of the other partitions by rightclicking on the partition you want to expand/shrink to Extend, the choose space from the empty partition: How to extend partition easily with Partition Wizard - video help.

The 212 gb unused space at the end of the drive is only invisible to Windows, it is actually Acronis Secure Zone this is a hidden area where I do automatic daily incremental backups, followed every two weeks by a Full Backup to an external drive.

Thank you.

Sounds like a plan.
