Grub not seeing Opensuse

WinBtrfs https://github.com/maharmstone/btrfs

WinBtrfs is a Windows driver for the next-generation Linux filesystem Btrfs. A reimplementation from scratch, it contains no code from the Linux kernel, and should work on any version from Windows 7 onwards. It is also included as part of the free operating system ReactOS.

Also you can use ReactOS, but this is a painful way.

It is better to use Linux LiveCD (LiveDVD).
