I'm having almost the same here! I have 2 HDs, the first had only the Ubuntu 9.04 32-bit version instaled and the second has Windows XP.
I decided to format the one with Ubuntu, to install the 9.10 64-bit version. (my PC suports amd64) After install via Live CD, the boot always stop at this Grub Error 2. And I can't start the system. -- Won't boot, GRUB Error 2 @ first boot on 9.10 https://bugs.launchpad.net/bugs/482990 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
