Ho installato per la prima volta Fedora su un sistema UEFI. Sembrava andato tutto bene, ma al riavvio parte sempre Windows.
Il partizionamento manuale che ho seguito è stato:
sda12 / (ext4)
sda9 /home (ext4)
sda10 /boot (ext4)
sda2 /boot/efi (efi) <-- è anche la partizione efi di Windows!
sda9 swap
[code]# gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 1465149168 sectors, 698.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): B25A3CBF-EC07-43AA-A25F-636A24D3662D
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 1465149134
Partitions will be aligned on 2048-sector boundaries

Se disabilito il secure boot o se attivo la modalità legacy non cambia nulla, parte sempre Windows (dove ho già disabilitato da Pannello di controllo la voce “Attiva Avvia Rapido”).
Ho provato a creare un chroot come segue (gli UUID li ho presi dall’/etc/fstab presente nella partizione dove ho installato Fedora):
[code]# mkdir /mnt/sysimage
mount UUID=18c4f8d2-df1e-4414-8df9-a3d5fefb76e0 /mnt/sysimage
mount UUID=89980680-088c-4d46-b9c5-0d867b64ba32 /mnt/sysimage/boot
mount UUID=3A55-4EE1 /mnt/sysimage/boot/efi
mount UUID=576e65a7-f4ae-4125-87ab-77ff9b271a7e /mnt/sysimage/home
for i in {/dev/,/dev/pts/,/proc/,/sys/}; do mount -o bind “$i” “/mnt/sysimage$i”; done
chroot /mnt/sysimage[/code]
Dal chroot ho provato a reinstallare grub, ottenendo un messaggio di errore:
# grub2-install /dev/sda
grub2-install: errore: /usr/lib/grub/x86_64-efi/modinfo.sh doesn't exist. Please specify --target or --directory.
Ho anche, sempre dal chroot, ricreato i file di configurazione di grub come segue:
# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfgLa cosa strana è che non c’è la voce relativa a Windows, ma siccome Fedora non parte, di questo ci occupiamo più tardi:
# cat /boot/efi/EFI/fedora/grub.cfg | grep "^menuentry"
menuentry 'Fedora, with Linux 3.17.4-301.fc21.x86_64' --class fedora --class gnu-linux --class gnu --class os --unrestricted $menuentry_id_option 'gnulinux-3.17.4-301.fc21.x86_64-advanced-18c4f8d2-df1e-4414-8df9-a3d5fefb76e0' {

Ho letto http://docs.fedoraproject.org/en-US/Fedora/18/html/Installation_Guide/ch19s02.html pagina dove parla di efibootmgr; siccome non ho capito bene i numeri che dovrei inserire, per ora ho solo verificato la situazione attuale:

Cosa dovrei fare per far partire Fedora?
