An error occurred during the repair.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sda2 file!

If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS does not allow to change the boot order, change the default boot entry of the Windows bootloader.
