Replace Win10 with EOS, keep other Linux install

General system EndeavourOS installation

I have a Win 10 install I don’t need, but want to keep the existing Ubuntu install. Here is my “fdisk -l”:

Device     Boot     Start        End    Sectors  Size Id Type
/dev/sda1            2048     206847     204800  100M  7 HPFS/NTFS/exFAT
/dev/sda2          206848  723802111  723595264  345G  7 HPFS/NTFS/exFAT
/dev/sda3       723802112  724723711     921600  450M 27 Hidden NTFS WinRE
/dev/sda4  *    724723712 1953523711 1228800000  586G 83 Linux

EOS grub can handle the boot, so just delete the NTFS partitions, and choose the freed disc space for EOS install?

That’s how I would do it.

you can check before install

inxi -Fza 
test -d /sys/firmware/efi && echo efi || echo bios
sudo parted -l

Looks like sda2 and sda3 are nfts partitions. The sda1 is the esp that you don’t want to delete.
You can verify this by showing the output of

lsblk -fm

Note that you can reformat the ntfs partitions with gparted into e.g. ext4.

Whatever you do, check that UUID values in files /etc/fstab and /boot/grub/grub.cfg are correct on both linux systems.
