I decided to dual boot Windows 7 pro 32bit and Windows 10 pro 32bit to just goof around on this older Dell I still have but I noticed that when I boot into Windows 10, in my Dell GX620 Pentium D, my backup IDE drive does not show up. I have 2 SSD sata drives for each system and this older Dell still has an IDE configuration to use another Hard drive which shows up in Windows 7 but not in 10. The IDE is just a 3rd drive for backup purposes.
As a side note, I still hang on to Windows 7 on several much better computers and do not prefer Windows 10 but decided to get used to Windows 10 using this dual boot configuration. I find the dual boot configuration using Windows 10 slower than when I dual booted Windows XP and Windows 7. Amazingly the SSD drives improves this Dell pentium D computer which is otherwise sluggish on regular platter hard drives. One could use this easily for basic computing. I used 32bit because I didn't want to add more memory. It only has 3 gigs of memory.
