12.04 - clean installation failed on APT configuration failure

  • 772

I tried to install Ubuntu 12.04 on the partition where I had Ubuntu 10.10, by first formating the partition (ext4) and keeping the same partition settings (the mount point is '/').

I use the Ubuntu installation disk I made on a USB drive.

Installation went fine until an error indicating a failure in APT configuration from the CD .

And now the system isn't bootable anymore :

Grub error, file not found

What can I do ?

installation 12.04

    Using discussions on a French forum, I could determine (no real proof or explanation) that you cannot install Ubuntu 12.04 64 bits using a start disk made on Ubuntu 10.10 32 bits.

    I solved the main problem by making another start disk, this time from a Ubuntu 11.04 (32 bits) computer.

    Another thing I got (from here, thanks beeju who gave the link) is that if your grub menu isn't working (due to a bad installation point or a crash at the bad time) you can reinstall it without problems : How can I repair grub? (How to get Ubuntu back after installing Windows?)
