[serlex]

Hey

I had to reinstall Windows, which has obviously overwritten my lovely Ubuntu Natty

I would like restore grub2, however failling to do so

I'm running:

sudo mount /dev/sda1 /mnt/boot
sudo cryptsetup luksOpen /dev/sda5 crypt1
Enter LUKS passphrase:
key slot 0 unlocked.
Command successful.

However

sudo pvscan
 No matching physical volumes found

Please help

cannot stat /mnt/boot/grub/boot.img

/boot is mounted, however boot.img is a mess (characters of shapes)
