I had a partition (sda11) which Ubuntu 11.10 was installed on it.
I resized this partition from 34 GB to 150 GB.
Then I lost the GRUB menu.
I use the Boot-Repair application to fix it.
But now when I restart my PC, only Microsoft Windows XP will boot and the GRUB menu not shown.
I tried to use grub-install, grub-update, grub, Bootable MBR Repair Softwares, and ..., but nothing appened !
I try to install Ubuntu again on sda11, but the installer say : "Saving installed packages ..." 'til now !!
