Hello,

On a dual boot machine (one fc32, and one fc34).
after I upgraded the fc32 to fc34, I cannot boot on the new fc34.
I get
failed to mount /boot/efi
/boot/efi is shared by both machines

Here is the fstab of the fc34 machine

#
UUID=a5b809ae-61c2-4d67-b0f3-109e99faad39 /                       ext4    
defaults        1 1
UUID=B2EF-0CE4          /boot/efi               vfat    
umask=0077,shortname=winnt 0 2


The /boot/efi seem correct (it is currently mounted by the fc32).

blkid |grep B2EF
/dev/sdb1: UUID="B2EF-0CE4" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System 
Partition" PARTUUID="0fe1d405-6683-456c-a306-140e882e322c"
 blkid |grep 9faad39
/dev/sda6: LABEL="fedora_rescue" UUID="a5b809ae-61c2-4d67-b0f3-109e99faad39" 
BLOCK_SIZE="4096" TYPE="ext4" PARTLABEL="OS" 
PARTUUID="41b9d134-b477-4ef5-8602-15fdc482a51e"

What should I do ?
It seems that the installer create /boot/efi/EFI/fedora/grub.cfg
with
search --no-floppy --fs-uuid --set=dev a5b809ae-61c2-4d67-b0f3-109e99faad39
set prefix=($dev)/boot/grub2
export $prefix
configfile $prefix/grub.cfg

(I could not boot either)
Then I run (from the fc32)
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg.new

and used this file to boot (by renamed).

But I still have the same issue.

What to do?
It seems that there is a similar issue inb
