problem with installing and booting ubuntu

[Jaromir]

I have tried to open gparted, removed all partitions and created one 150 MB at the beginning (unformated grub_bios flag), then one 4GB less than max (ext4), then the rest 3.72 GB (linux-swap).

Then I ran boot-repair - everything went smooth (summary: Boot successfully repaired.

Please write on a paper the following URL:

In case you still experience boot problem, indicate this URL to:

You can now reboot your computer.)

Then I tried to install ubuntu, using the USB stick that I am running the live session with.

Made the Ext4 mount point at "/" and began to install.. everything went fine until the "grub2 installation" then a failure message appeared and the installation closed.

Thanks for any advices..

You do not need an unformated "bios_grub"-partition for an UEFI installation.

You need an EFI-System-Partition with FAT32 and mounted on /boot/efi
