I have windows installed on my harddrive and I d like to repair windows, I extracted a content of a windows iso to a NTFS partition for it and I installed grub2 on my puppy live cd but when I do "grub-install /dev/sda/" I get as output

Code: Select all

Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `unionfs'.
