I have similar concerns about upgrading to Win 10...
We have 2 Lenovo laptops
T520, i7, win7 Pro, SSD
E520, i5, win 7 home, regular HD
Laptops are about 5 yrs old i think...
I am also on the fence about upgrading, due to all kinds of mixed reviews and fears something wouldn't work, etc.
For those who you upgraded to Win10:
did you guys do any of the recommended BIOS updates for your laptops before upgrading?
Should I do the BIOS upgrades? when I look under the system update, almost all bios updates are for preparing for Win 10.
Also, can I backup my SSD like a normal HD using Macrium Reflect ?
