Okay, the proposed lupin package did not completely break my system, it was a USB mouse I have that makes ubuntu not to boot when connected, sorry about that.
However, I can confirm, that the proposed package per-se won't fix a system in this state, I have to continue booting by usingthe aforementioned commands from the Grub shell. -- After 9.10 grub update can not boot into Wubi install https://bugs.launchpad.net/bugs/477104 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
