[SOLVED] Path `/mnt/boot/grub' is not readable by GRUB on boot.

Hello,

I try searching in the forum, but I did not solve anything.

So, this is the problem.

I installed winzozz on an arh installation, and now I have to react grub2.

I run from fedora live

mount /dev/sda1 /mnt/
mount /dev/sda2 /mnt/home
chroot /mnt
grub-install --target=i386-pc --recheck /dev/sda

but

Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible. Aborting.

How can I solve this problem?

[root@localhost ~]# fdisk -l

Disk /dev/sda: 120.0 GB, 120034123776 bytes, 234441648 sectors
Units = sectors of 1 * 512 = 512 bytes

Thank you.
Riccardo


P.S.: I have installed winzozz ONLY for work smile

Did you not bind mount /dev?

Re: [SOLVED] Path `/mnt/boot/grub' is not readable by GRUB on boot.

Your boot flag is set to sda3 , I would give it a try to change it to your boot partition

Can you confirm that there's a boot/grub dir?

do you have any other HDs? what's their BIOS order?

I solved with:

cd /mnt/
mount -t proc proc proc/
mount -t sysfs sys sys/
mount -o bind /dev dev/
mount -t devpts pts dev/pts/

Now I try to boot.


Thank you!

Re: [SOLVED] Path `/mnt/boot/grub' is not readable by GRUB on boot.

With os-prober installed, I run

grub-mkconfig -o /boot/grub/grub.conf

but win doesn't appear at grub.

This is my grub.conf:

Re: [SOLVED] Path `/mnt/boot/grub' is not readable by GRUB on boot.

I noticed that at the boot in grub.cfg doesn't appear winzozz. So, to solve, I put with vi the section above of win in grub.cfg and now it works!!


Thank you.
