Is it possible to install Libreelec to a partition (instead of the whole drive)

It sounds like you are searching for PINN or NOOBS https://github.com/procount/pinn

You'll find more info about these on the RPi forums https://forums.raspberrypi.com/

I'm not sure if there's an easy way to do that. Best check through PINN's readme https://github.com/procount/pinn/blob/master/README_PINN.md and the PINN support thread on the RPi forum https://forums.raspberrypi.com/viewtopic.php?t=142574 - if you have questions better post there, I never used PINN myself yet (and IIRC none of the other LE developers did either).

Take a backup of the .kodi folder and contents from the RPiOS install, store it somewhere safe. Once you installed LE via PINN or NOOBS for some level of multi-boot support you can copy the backup file over and manually restore content by stopping Kodi, moving files to the right places, restarting Kodi again.

NB: It is not possible to install LE into a partition. It is not possible to use an NTFS drive as the /storage partition. You can use the NTFS drive as a separate media drive that's shared between several OS without issues, but /storage needs Unix filesystem permissions support.

liberi That isn't going to work on an RPi4 which doesn't use Grub2 (or any other normal bootloader).

But he can use u-boot, and than grub2?

RPi4 can boot via u-boot, but it's not needed and we don't use it with LE images for RPi devices. And if the user needs to ask Q's at the current level the likelihood of them building a custom image that implements u-boot support for RPi in LE is rather unlikely IMHO.

Quote from twilightened

Is there a key combination that will allow me to select the boot source on Raspberry Pi 4 while booting? Let's say i want to boot the usb stick when the sd card is inserted. Is it possible to do so?

No, you can only configure the boot priority/order.

Please note rpi-eeprom-config --edit may revert the bootloader version to older release.
