I have Linuxmint installed on the computer, and I wanted to install Ubuntu. All installation went smooth, but at the grub-2 installation, system stopped. I cannot install Ubuntu.

Your disk is currently partitioned to boot in bios mode, but you booted the installer in EFI mode. A warning message prompted you that this could be a problem and recommended performing a bios mode install instead, but you chose not to. You either need to perform the bios mode install, or partition the disk using GPT and set up an EFI system partition to install in EFI mode. This will be done for you if you choose the "use entire disk" guided install option.

Dear Philip,

Thank you for the answer. I did not use the "use entire disk" because on
second partition I have the Home folder, 725 Gb. I'll try it on the new
computer.

Once again.
Thanks.
Andy
