Hello, I think I’m correct, but I’m not an expert.
Yes but no. There is not automatic renaming of Linux partitions. Unless you delete too sda2 and recreate a partition. The new one should be named sda1.
The order too is not automatic. From left to right you could have sda1, sda4, sda2 and sda6 by ex, depending of your previous operations in partitioning.
Still sda2. I’d recommend grub and mkinitcpio updates. And careful on which partition grub is installed. If you have it on sda1, you’d want to install it on sda2 before deleting sda1…
You may still do it afterwards in chrooting in a Live iso session.
If Grub is installed on sda2 and you had previously updated it, only sda2.
Install, depends if it’s currently on sda1 or sda2. Update, sure, you have to.
So if I read well, sda2 has grub installed already, so no need to reinstall it then.
You go into live USB environment, delete your sda1… Then if the empty space is left of sda2, it could take some time to expand and be a risk to lose data. Because all your sda2 data will be moved bit by bit at sda1 previous location. With SSD could be quite quick, with HDD, if it’s a big partition, expect some hours.
After that, a chroot in your system with a sudo update-grub and a sudo mkinitcpio -P should be good.
All very helpful thank you, although i must admit even though i keep seeing chroot mentioned i have never got around to reading up on what it actually is or does. Probably time for me to go and look up chroot and mkinitcpio.
I could, but it really is the absolute last thing i want to do because i have just spent weeks reinstalling and creating new user profiles to try and track down some intermittent issues i have had for a long while. This current installation on sda2 is the first time i have got the OS to work (touch wood) i am just now migrating all my ~/ stuff one folder at a time very slowly to be sure the faults do not reoccur.
Iv never separated /home i just back it up where it is on /.
First, backup valueable data. Then just move/delete the unwanted system partition, manjaro-chroot from live ISO into the partition you want to keep and perform a fresh grub-install with the right syntax for your system, afterwards (still in chroot environment)
Well i was happy with the idea that i could just delete sda1 and reboot. Since sda2 is formatted as boot and already has grub it should still boot and then i can update-grub from inside the correct session.
Which has confused me again. I thought grub is installed on specific /boot blocks so if you had multi partitions with many OS’s how would it know which one you want it on? is it the current session you are using that defines it?
No matter, i think iv got enough here to be tinkering with at the time.
