hello,everyone!
I make a liveCD,and used grub2. I boot livecd ,and I found a problem.I executed "grub2-install /dev/sda" failure.and reported follwing error:
# grub2-install /dev/sda
grub-probe: error: no mapping exists for `live-rw'
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.
why need to detecting livecd root? I executed "/usr/sbin/grub2-setup --directory=/boot/grub2 --device-map=/boot/grub2/device.map /dev/sda" ,also reported as some error.
# /usr/sbin/grub2-setup --directory=/boot/grub2 --device-map=/boot/grub2/device.map /dev/sda
grub-setup: error: no mapping exists for `live-rw'
df -h command results:
# df
