edit the grub.cfg allows to mount partitions for Android X86

[Token David]

I need the Android X86 to mount other partitions in my computer,such as Disk D(sda5)、Disk E（sda6）and Disk G（sda7），https://www.reddit.com/r/RemixOS/comments/430hpx/question_does_remix_support_ntfs_partitions/
from this thread i know how to edit grub.cfg to mount the Disk D as SDCARD,the grub.cfg like this:
------------------------------------
menuentry 'Remix OS ' --class android-x86 {
search --file --no-floppy --set=root /kernel
linux /kernel root=/dev/ram0 androidboot.hardware=remix_cn_x86_64 androidboot.selinux=permissive quiet DATA=/data SDCARD=sda5 CREATE_DATA_IMG=1
initrd /initrd.img
------------------------------------
now,i want to mount both Disk D E and Disk F on the Remix OS,how to edit the grub.cfg? please tell me ,thanks in advance！
