Do you think that if I flag /boot to sda1, it may break windows and Ubuntu boot?
That’s what I was worried about because normally you don’t need a boot partition. I thought that is just put the boot files on the same root partition and it puts grub on /dev/sda. It’s been a while since i used my Bios machine and had Windows on it too. I’m so used to UEFI now i don’t even think about it.
Okay i think i realized what you are doing wrong.

When you go through it again and if you are using manual partitioning just edit the current partition /dev/sda4 and mark as root with the / and then below in the window put a check mark in boot then edit /dev/sda6 and mark as /home but don’t format it. grub should install to /dev/sda automatically
Edit: You probably didn’t put the check mark in boot when you created the / partition

on gparted image i can see boot flag is on sda1 it should be on the one using for endeavouros / (root) (sda4 in the image), as if you install with grub it will take over boot process and needs to read grub files from endeavouros root partition (/boot)

From parted here’s how mine looks. I only flag boot on the efi partition. Every Linux distro works:
Number Start End Size File system Name Flags
1 1049kB 123MB 122MB fat32 EFI system partition boot, esp
2 123MB 105GB 105GB ntfs Basic data partition msftdata
3 105GB 107GB 2097MB linux-swap(v1) swap
4 107GB 159GB 52.4GB ext4
5 159GB 204GB 44.2GB ext4
6 204GB 256GB 52.4GB ext4

Not sure if you understood the messages? Boot flag is set as sda1.Don’t know how you did that. When you tried the install of Endeavour and created the / partition for the install you also needed to mark it also as boot in the window below. Then edit and mark your existing /home partition.
Is it currently booting on Ubuntu and Windows?
Sorry for the late reply, but Endeovour forum stopped me temporarily from replying because I am a new user and had already reached the maximum number of replies… Installation of EndeavourOS worked fine up to final and it is booting correctly. Windows also boots correctly. Only Ubuntu did show errors of corrupted partition and did not boot, but after cleaning with fsck /dev/sda5 it boots again.
So Rick your help was critical to get it working. I did not imagine that the little boot flag was so important to have it working. I want to warmly thank you very much for your dedicated thoughtful attention. Thanks to the others as well
