Safest way to remove other installed OS
This is my current configuration
Device Boot Start End Sectors Size Id Type
/dev/sda1 2048 743215128 743213081 354.4G 83 Linux
/dev/sda2 743217150 976771071 233553922 111.4G 5 Extended
/dev/sda5 964487168 976771071 12283904 5.9G 82 Linux swap / Solaris
/dev/sda6 * 743217152 744265727 1048576 512M ef EFI (FAT-12/16/32)
/dev/sda7 744267776 860537355 116269580 55.5G 83 Linux
/dev/sda8 860538880 964478975 103940096 49.6G 83 Linux
And here the explanation, yesterday I have changed my computer. All hardware is new, except the hard disk, where I have a working Ubuntu 18.04 (/dev/sda1)
When I tried to boot the computer, it gave some errors so I tried to fix it by booting with USB device
/dev/sda7 refers to the first try, I installed a new Ubuntu alongside the old one, using free space in HD... Grub was not loading, so I made a second try, installing again a new Ubuntu alongside the others, using more free space. /dev/sda8 refers to that second try
Later, I found a solution & I have been able to boot the old Ubuntu... so now I want to safely delete that 2 new installed Ubuntus
After reading this Proper way to remove other operating systems after installing ubuntu? I am not sure if just deleting that 2 partitions would be a good idea, as they are the most recent OS in the computer
Any tips?

I suspectupdate-grubwon't be enough; yes it'll update the grub menus to reflect the removed partitions, but if the soon-to-be-killed OSes owned the boot sector I suspect you'll need to ensure MBR points correct and I'd suggest also runninggrub-install(help.ubuntu.com/community/Grub2/Installing in the re-installing from a working system section). @LeonidMew's advice was good, but addinggrub-installwon't create any problems and may be necessary in my opinion (if your kept OS wasn't the last installed)
