Please help me to find out what's wrong with my system. I installed Windows 7 64 bits on an other disk when I upgraded from Windows XP pro SP3. It works well but when I installed Paragon Drive Backup 9 64 Personal on W7 it shows the disk with W7 as red and labeled Invalid. I am a newbie but I think it has something to do with partitions I have on my disks. In the Control Panel it looks like this: Disk 0 Simple Basic NTFS Healthy (Active, Primary Partition) -Here I have my Windows XP Disk 1 Simple Basic NTFS Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition) Here I have my Windows 7 and this is Invalid in Drive Backup 9 Disk 2 Simple Basic NTFS Healthy (Logical Drive) Disk 3 Simple Basic NTFS Healthy (Primary Partition) This one is external USB disk Disk 4 Simple Basic NTFS Healthy (Active, Primary Partition) This one is external USB too What I should do? And please, if you want help me don't forget that I am newbie on this so I need detailed instruction, please!
