My notebook (Dell Inspiron 14r 5437) has already had windows 8.1 installed. I want to install Ubuntu in dual boot, however I'm having the following error after partitioning the required partitions:
The partition table format in use on your disks normally requires you to create a separate partition for boot loader code. This partition should be marked as a "Reserved BIOS boot area" and should be at least 1MB in size. Note that this is not the same as a partition mounted on / boot. If you do not go back to the partitioning menu and correct this error, boot loader installation may fail later, although it it may still be possible to install the boot loader to a partition.
I followed this tutorial and after part 6 where I click on install appears the message above, having the option to continue (with the risks warned) or go back and correct, but I was in doubt, because in the tutorials I saw did not appear this message.
