GRUB 2 does not show more than one RebornOS installation

Issues & Assistance Installation and Live media
1

On my PC i have 4 disks, 2 HDD for storage and 2 SSD for my Operational Systems.
In sda i have installed LMDE in sda1 LINUXMINT 20.1 in sda2 SOLUS IN sda6 and KDE NEON in sda7.
LMDE’ S GRUB is installed on sda MBR and for the other OS’ s are installed on the / (root) partition of the OS.

sda
sda1176×740 122 KB

sdb is used for testing purposes mostly and it is setup as shown in the following image
SDB 2
SDB 21075×438 49.4 KB

MANJARO’s GRUB is installed on sdb MBR and sdb is set as the first boot disk in BIOS
I wanted to install more than one REBORNOS with different DE for testing, but every time i install a new REBORNOS i loose the previous REBORNOS installations from GRUB.
And to be more specific, during the installation i choose not to install a boot loader because i allready have one, after the REBORNOS installation is done i reboot the system to MANJARO and update GRUB as shown in the image

update grub
update grub754×569 94.9 KB

but when i reboot i can only see the last REBORNOS installation on the GRUB menu as shown on the image

333333331440×809 91.7 KB

The same thing happens if REBORNOS is installed in sdb1 instead of MANJARO
Do you have any idea why this is happening?
I do not upload my system info because the post is already big and i do not want to make it bigger, if you need my system info pls let me know

Here is MANJARO’S grub.conf

Have you tried installing Linux Mint 20.1 Ulyssa twice? You will see that it will not be possible. This is because the entries in Grub are exactly the same (in name), and the latest installation of for example Linux Mint Ulyssa (assuming a double installation) will replace the entry from the previous installation.

To install more than one DE, you can try Virtualized RebornOS, or install several DE in the same RebornOS installation, being careful when installing KDE together with some other DE, which is when there may be a problem. It is best to virtualize the installation.

That is what I see here. I never tried something like that anyway.

I take the opportunity to say hello, and have a nice day!

Before the setup shown on the above image, i had installed in sdb1 Manjaro Gnome, sdb2 Manjaro KDE, sdb3 Manjaro Cinnamon and sdb5 RebornOS Cinnamon, all the Manjaros were the same edition and they were running flawlessly with no problem. Even before that i had installed Solus Badgie, KDE and Gnome without problems either. Then i decided to replace Manjaro with RebornOS and i faced the problems i mention above. Maybe it is because there is no option to install GRUB on the root partition… i don’t know… grub keeps the last installation maybe that means something …i don’t know i’ m confused

5

George.LG: Do you like RebornOS, or do you like testing installation much more? Because it would be very useful to have you to perform these tests for us. If you are interested.

6

I like RebornOS, it is Arch the easy way, i like that i can choose the DE during the installation process, it is a very good OS, you have done great job. I like testing OS’s because i thing it is the only way to find out which one is better for me, yes i’d like to help you by performing test for you, but you have to be aware that my knowledge to Linux is limited and that you have to give me instructions on what you want me to test. The above post gave you an idea on how i use my PC, if you think that i can help then i will be glad to.
