本文记载win10与gentoo双系统分区。参考这里。

环境准备

同时需要禁用掉快速启动。原因是：Without it, Windows' filesystems are not unmounted even when you're using Linux, so editing Windows files can result in data loss. Even if you do not intend to share filesystems, the EFI System Partition is likely to be damaged on an EFI system.

刻录SystemRescueCd并进入系统，开始分区。
