Grub 2.02-beta is not working.

Asked by smurf

I recently upgraded from 12.04 to 14.04, Gnome FlashBack, almost everything is ok, but Grub is a nightmare.
I have a separate partition for /boot (/dev/sda1) because I always have a partition with installed the system working (now /dev/sda2) and another partition with an experimental installation (now /dev/sda3), when I decide that the new installation is ok I simply change grub.cfg script and my family automatically use the new system without to sense the change.
Upgrading to 14.04 carried the new grub version 2.02-beta, but there is no way for me to put it to work. After a fresh install of Grub I reboot and the grub crash to a "grub rescue>" prompt.
The solution I found now is to mix the contents of old install of grub 1.99 and the new install of grub 2.02-beta, the system gives me some "error: file not found" messages, but boots.
Now, my questions:
1) how can I get a functioning install of Grub 2.02 ?
2) why I receive a message "Hit any key to continue " when booting the new kernels for 14.04?

OK, sorry for delay.
I found the solution. The problem was a conflict between some files in grub partition. i wiped the partition and re installed grub and now everything is fine.
