A friend recently brought in an old Fujitsu laptop and asked me to reinstall the OS on it and moved all his data to partition D on the same hard drive. He had Windows 7 but wanted me to try installing Windows 10, but because the specs weren’t really that good I decided to just go with Windows 7. After formatting the primary partition (C) in the install setup, I installed Windows 7 on it. The laptop booted up, but when I opened up Windows Explorer there was no secondary partition (D) showing up, just the one Windows was installed on. I went into the setup again to see if I accidentally deleted the partition, but it was still there with the same ammount of data on it and it was labeled “System”. Is there any way to try and get the data on this partition back?
