I can't install grub2 on my system. i followed the guide, but when i chroot on my ubuntu partition and type:
grub-install /dev/sdb
I get this error:
root@ubuntu:/# grub-install /dev/sdb /usr/sbin/grub-setup: error: hd0 appears to contain a iso9660 filesystem which isn't known to reserve space for DOS-style boot. Installing GRUB there could result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup (--skip-fs-probe disables this check, use at your own risk).
Here is sudo fdisk -l output:
