greets!

yrs ago I thought BIOS was mysterious; I didn't anticipate UEFI!

was travelling, my SSD collapsed - dead - and I had to get another and get Linux installed fast. put Kubuntu on; back home added tde.

I just resized the partition and added another ext4 with exegnu installed but I installed the loader to the partition, fearing to touch /boot/efi.

so there's boot/efi on sda1, kubuntu on sda2 and exegnu on sda3.

there's some crap in my efi because of other misadventures but the important thing now is I can boot into kubuntu, what do I do so I can put into exegnu also?

is it simply a matter of grub-install? other magic?

my ultimate goal is to remove kubuntu and install Windows 7 with exegnu as the default boot.
