installation of 16.04 crashes on installing grub, even skipping does not work

[toby hijzen]

I am trying to install ubuntu 16.04 on an lvm partition created on my main disk where a windows partition is also present. I was using 14.04 and grub before. But now it crashes upon installation as grub cannot be found. Even though I end up in grub on bootup. I've tried selecting both sda and sdb as disk containing grub but installation fails. Even trying to skip setting up of grub didn succeed.

Your disk appears to have been partitioned under an ancient partitioning tool that did not leave enough room for grub to install. You will need to remove at least the first partition and recreate it so that it leaves the proper amount of space.
