Or perhaps i should call this “Do you remember i was upgrading to Ubuntu 11.04 ?”.
Well something is gone bad and when i rebooted to start my new Xubuntu 11.04 i got:
error: cannot read the Linux header. error: you need to load the kernel first. Failed to boot both default and fallback entries. Press any key to continue...
During the upgrade, Ubuntu has removed all old Kernel but one, and so..i find myself without a way to boot my machine.
Fortunately I did a lot of experience with Gentoo in the past, that on this occasion was very useful to recover the system.
