One thing, I tried renaming with e2label, but its not found, so I need to install it, but the system isn't operational (sudo apt-get not found, apt-get not found etc)
I'm pretty sure I remember renaming partitions with e2label.
Just tried in putty on my Beelink:
Beelink:~ # df
Filesystem           1K-blocks      Used Available Use% Mounted on
devtmpfs                827928    134820    693108  16% /dev

tmpfs                   931764         0    931764   0% /tmp
Beelink:~ # e2label /dev/sda2
LIBREELEC_DISK
Beelink:~ #
That's obviously telling me my storage partition has the right name (LIBREELEC_DISK).  But if not I'd be running:
e2label /dev/sda2 LIBREELEC_DISK
The problem with the above, of course, is that if it doesn't boot you can't SSH in.
So what I'd do is boot from a fresh sd card / usb (or use another instance of libreelec if you have one), stick your sd card in a card reader and plug it in a usb port,  open putty, run 'df' to find the relevant partition and then e2label (carefully) to rename it.  And if I was bothered about what was on it I'd image the card with eg win32diskimager or usbit before I started.
Disclaimer - I'm also a windows user who just mucks about with this linuxy stuff.
