im currently dual booting endevouros with windows, and i have a lot of free/unpartitioned space on my drive. can i install another linux distro alongside endevour and windows? i have a separate home partition as well. do i only keep one linux/grub boot partition? im not too scared of nuking everything but id obv rather not. thanks!
Gparted should help you manage your partitions. Be very careful to pick the right partition to format. Also, Windows is known to sometimes mess up dualboots, it thinks it is the only OS.
I would never ever recommend not updating windows, but if it is maybe just a dedicated gaming OS and you don't use it for internet browsing or anything else, you might be able to get away with it.
