[SOLVED]Grub Fail to Install

[Guest]

Hi, I installed 11.04 yesterday on my notebook and everything worked (except the keyboard configuration as Pragrammer Dvorak), but today I tried to install on my desktop using the same usb drive and I got an error saying that grub could not be installed.

I use a SSD as / and two disks in "asus superspeed"(Raid 0 for dummies) as my /home
May this be the cause?

I believe grub is the last step of installation process, can I use 10.10 to install grub as if I was recovering it?

Re: Grub Fail to Install

great, it is working now!

just in case someone have the same problem, this is how I solved it

booted the same media as livecd
verified which disk was the boot disk

fdisk -l

in my case it was /dev/sdb
and my / was /dev/sdb5
then I mounted the disk in mnt

sudo su
mount /dev/sdb5 /mnt
mount -t proc /proc /mnt/proc
mount -t sysfs /sys /mnt/sys
mount -o bind /dev /mnt/dev

then I swiched to /mnt and instaled grub

chroot /mnt
update-grub2
grub-install /dev/sdb


everything worked as expected

PERFECT -- very nice job, Rodrigo! Here we have in two simple posts, the description of the problem, and a perfect guide to using chroot to fix it by installing grub-pc to the mbr of the affected drive.

Nice job!
