I am trying to install another linux distro besides ubuntu. However, I want to retain my existing windows based loader. Currently, as per my knowledge, MsDos loads grub which then loads Ubuntu (with loop back trick).
Now, I have a new linux distro installed on /dev/sda8 (/boot for new distro) where as /root for that OS is installed on /dev/sda9.
I tried following steps
1. Add entry into 40_custom of ubuntu grub
2. update grub
But upon booting via that entry, it is not able to load the new OS and shows me blank screen. What could be the problem?
