Are you sure your model has drivers for everything for Windows 7. I can't guess why W7 but it would be best to run it in a VM like VirtualBox since you could lose days trying and failing to get W7 working right.
Hi, I just bought a new Lenovo Thinkpad equipped with 2x SSDs and 1x HDD each 1TB. It is preinstalled with Win 10. Upon launching Disk Management, the Volumes are as follows:
Disk # / Volume / File System / Status / Capacity / Free Space
===========================================================
Disk 0 / Data (D
/ NTFS / Primary Partition / 953.74GB / 953.49GB
Disk 1 / Partition 1 / - / EFI System Partition / 260MB / 260MB
Disk 1 / Windows (C
/ NTFS / Boot, Page File, Crash Dump, Primary Partition / 952.62GB / 882.96GB
Disk 1 / Partition 4 / - / Recovery Partition / 260MB / 260MB
Disk 2 / Data (E
/ NTFS / Primary Partition / 931.39GB / 931.14GB
My first question is why the difference in capacity (953.74GB, 931.39GB) between disks 0 and 2 (volumes D: and E
although both are 1TB and empty?
My second question is, how can I install Win 7 Pro using USB Flash Drive to my 2nd SSD labeled Disk 0 - D: while being able to share Disk 2 – E: for data between Win 10 and Win 7?
