Old Mac & Lenovo Windows10 startup Sequence 

古めのMacBook Pro 2010とMacBook Air 2011とLenovo V310オリジナルWindows10の起動比較です。
MacBook AirはSSDなので比較的早い起動ですが、BootCamp経由なのとドライバーがWin10に適切じゃない可能性があり本家Lenovoより遅かったです。
MacBook Pro 2010はさすがにHDD起動やらドライバーの関係か一番遅かったですね(^^;;
それでも起動しちゃえば普通に使えます。

Old MacBook Pro 2010, MacBook Air 2011 and Lenovo V310 original Windows10 startup comparison.
MacBook Air is SSD, so it starts up relatively quickly, but it was later than Lenovo because it was via BootCamp and the driver might not be suitable for Win10.
As expected, MacBook Pro 2010 was the slowest in terms of HDD startup and driver related (^ ^ ;;
You can still use it normally if you start it.
