bootloader location
Sorry, an error occured and it was not possible to install the bootloader at the specified location.
How would you like to proceed?
Choose a different device to install the bootloader on: /dev/sdb
Continue without bootloader.
Cancel installation.
Solution 1:
Select the option "Continue without bootloader".After the successfull installation of Ubuntu, don't forget to run boot-repair.
Boot repair will reinstall the grub on your disk.
Solution 2:
Run live Cd -----> open Terminal :
sudo mount /dev/sdax /mnt ( so you could read and write)
/dev/sdax
is the partition where Ubuntu os is installed.
sudo grub-install --root-directory=/mnt /dev/sda
/dev/sda
represents the first disk.
When installation finish :
sudo umount /mnt
Reboot
