1 Hi all. First at all i apologize if my english is not enough.
2 When I installed gentoo, I do that with UEFI, and gpt partitions. But
3 right now, I tried to install XEN, and this not works with EFI. I cant
4 wait until somebody fix this problem, So i'm thinking to change "EFI" to
5 "BIOS" boot.
6
7 So, I deleted the efi (/boot/efi) partition, edited make.conf, and deleted
8 /etc/default/grub.
9
10 After that, I made a new partition with bios_grub
11 flag. As explained in [1]. And reinstalled grub2 (with new flags).
12 But I can't boot. Anyway, I can boot from a live cd without
13 efi, so the problem is not in bios.
14
15 I can't find the problem. ¿Some ideas?

17 parted -l /dev/sdb:

19 Model: ATA KINGSTON SV300S3 (scsi)
20 Disk /dev/sdb: 120GB
21 Sector size (logical/physical): 512B/512B
22 Partition Table: gpt
23 Disk Flags:

25 Numero Inicio Fin Tamaño Sistema de ficheros Nombre Banderas
26 1 1049kB 11,5MB 10,5MB bios_grub
27 2 58,7MB 24,8GB 24,7GB ext4 rootfs arranque
28 3 24,8GB 28,8GB 3999MB linux-swap(v1) swap
29 4 28,8GB 120GB 91,2GB ext4 home
30
31 I made install with:
32 grub2-install --target=i386-pc --recheck --debug /dev/sdb
33 grub2-mkconfig /boot/grub/grub.cfg

35 Thank you in advance list! Bytes! ;)
