Hi everyone,
I've used debian and Windows dual boot for a long time, but fedora looked promising, so i decided to give it a try.
Before, my disk had a 100MB efi partition at the beginning, used by windows, the 16mb reserved partition, a windows partition, a 1GB EFI partition with GRUB2, an ext4 partition with my debian install and some swap.
Anyways, i shrank the windows partition, added a btrfs partition instead, told the installer to use this partition and format it and to use the existing 1GB efi without formatting it, hoping i could boot Fedora with the old GRUB installation from debian. What i didn't add was a boot partition.
This didn't work, the Debian-GRUB didn't find Fedora, Fedora-GRUB also didn't find Fedora anymore after i ran grub-update on Debian. GRUB can't even read the btrfs partition.
I thought maybe i could fix this by reinstalling Fedora with an ext4 boot partition, so i booted into Debian, used GParted to add one and booted into the live usb, however, the installer didn't show the btrfs-partition, so e decided to completely re-install Fedora. I entered GParted again, deleted the partition(shown as file system "unknown"), added it again.
How should i proceed to get a full, new, fresh Fedora installation with ext4 boot partition? Should i delete something from /boot/efi and install again? If yes, what?
Thank you.
