Partition Coloured Red And Marked As “Invalid”

Scenario

A Paragon program shows some of your partitions in red; instead of filesystem or unallocated space, they’re marked as “Invalid”

Reason

This typically results from incorrect geometry.

Solution

You need to fix it by slightly resizing partitions with Windows Disk Management:

1. Open Disk Management (rightclick bottom left and select “Disk Management” or “Start – Run – type: diskmgmt.msc”)
2. Right click on the respective “invalid” partition
3. Select “Shrink volume”
4. Reduce OS partition by 8 megabytes (or more depending on the mismatch)
5. Right click again – Extend volume
6. Restore original size
7. Restart OS

Now partition geometry should be correct.

After these operations, the partitions should show up correctly and be operable. It should be noted that partition shrink is only available in WDM starting with Windows Vista. In earlier versions of Windows, you need different tools.
