I would like to erase hera and install odin on top of it. I cannot use the erase and install option as it seems to erase all partitions on the disk and would erase windows data.
When using custom install, I need to choose a boot partition. I do not remember having done this for installing hera. I can see there is already an efi partition of 260mb (first partition on disk).
Do I need to use and select this already existing partition for boot? or create a new one of 260mb?
then I would create paritions for root home and swap as seems it would easier further upgrade or reinstall process in future. I would have 20gb for root, 60gb for home and 8gb for swap, all in ext4
