Incorrect Linux partition layout?

Question

linux

I want to install Ubuntu with the only system, because of this I demolished Windows. Now I'm trying to put ubuntu on a bare disk with the following partitions: / , swap, home. As a result, errors like this appear: 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 for use as “Reserved BIOS boot area” and should be at least 1 MB in size. Note that this is not the same as a partition mounted on /boot.
I am completely green in terms of Linux and do not know what partitions to create for bare Ubuntu without Windows second OS. I have BIOS on my computer, not UEFI.

Answer 1

just go to the console and run

; echo -e "label:dos\nstart=1M,bootable" | sudo sfdisk /dev/sdX

will create a dos partition table (aka mbr) and one partition for the entire disk with an indent from the beginning of the disk of 1 meter
where / dev / sdX (X can be a, b, c ...) this is your disk where you put what disks in the system you can take a look with the command
; lsblk
, don’t bother with partitions if you don’t understand what you need them for, swap can then be thrown into a file, and the hamster fundamentally lives well

Answer 2

Select "Automatically Partition and Use Entire Disk" during installation.
He will arrange the necessary boot-flags for you, and the root partition will normally install.
Also there should be an option "Separate partition for /home".
And so, in general, if you are interested:
Create a partition "/" with the boot flag and fs ext4, a partition "/ home" without flags with the ext4 file system, and a couple of gigs for swap with the swap file system

Answer 3

Turn off Legacy mode
