Restore grub after windows7 install

0

I get forgetting the steps so here’s a reminder.
When you dualboot with windows and install windows *after* Linux you’ll lose the grub menu and get into the proper OS anymore.
That’s not ideal.
So here the steps to restore the grub bootloader after windows has removed it.

  • Get a Linux live USB/CD/DVD and start it.
  • Start a terminal and type this
    sudo mount /dev/sda1 /mnt
    
    sudo mount --bind /dev /mnt/dev
    sudo mount --bind /proc /mnt/proc
    sudo mount --bind /sys /mnt/sys 
    
    sudo chroot /mnt
    
    update-grub
    
    sudo grub-install /dev/sda
    
    exit
  • reboot

Done.

 

 

ogg not playing on Kivy when packaged with pyinstaller

0

I’m working to package a Kivy based project for Windows7 by using pyinstaller and while following
the Kivy manual I noticed that all went well except for the ogg sound files I’m using.
The only thing one would notice when running the “exe” is that when playing the ogg you
would only hear a “click” iso the ogg sound file.
The solution¬† was to include by hand the the following DLL’s from site-packages/pygame:
libogg.dll, libvorbis.dll and libvorbisfile.dll to th eroot of the “exe” tree.
