Installed Ubuntu on HP xw4600 workstation using CD not USB. But after installation it does not boot from hard drive. During installation it showed:
The entire disk will be used: /dev/mapper/isw_digjcabegb_Volume0(ext4) 250.1GB Running “grub-install /dev/mapper”… Error pop-up: Unable to install GRUB in /dev/mapper Executing ‘grub-install /dev/mapper’ failed. This is a fatal error.
Then another error:
Sorry, an error occurred 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/mapper
/dev/mapper/isw_digjcabegb_Volume0 from the drop down menu and it gave me another error saying the at it failed again and this is a fatal error. Then it said installation complete and I need to restart the computer.
