I have created a dual-boot system starting with Windows 7. I then added a second system (Windows XP) on a separate drive (both drives are SATA drives but the Windows 7 drive is a Western Digital and the Windows XP is a Seagate. Both systems will boot when I select them but here is the strange thing. When running Windows 7 I can access both drives (7 and XP) but when XP is active I can "see" the Windows 7 drive but that is all I can do. I used the Disk Management tool and found that XP thinks the 7 drive is Raw data rather than NTFS and I am at a loss as to why or what I can do to correct it. I am uncomfortable messing with the drive with XP for fear of destroying the Windows 7 system. Has anyone seen this and have a solution or does this mean I didn't actually get the XP installation completed properly?
