首先我要说一下，我是 Linux 新手。我的主 SSD 上安装了 Windows 7，我想试试 Kali，所以我把它安装在了第二个 SSD 上。当出现安装 grub2 的选项时，由于之前使用过 Ubuntu，所以我把它安装在了主 SSD 上。我现在无法启动 Windows。我试了一下，结果显示sudo update-grub2：
Generating grub.cfg ...

Found linux image: /boot/vmlinuz-3.18.0-kali3-amd64
Found initrd image: /boot/initrd.img-3.18.0-kali3-amd64
No volume groups found
我运行了 bootinfoscript，得到了以下结果：
=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same
hard drive for core.img. core.img is at this location and looks for (,msdos1)/boot/grub
on this drive.
=> Windows is installed in the MBR of /dev/sdb.

我不知道如何重新启动我的 Windows 7。提前感谢你的帮助。如果需要任何其他信息，请告诉我。
