Hi!
Run as root in a Terminal / konsole:
Gnome: sudo command lines below, RETURN,
KDE: su - , RETURN, password, command lines below, RETURN ->

Code: Select all: fdisk -l 2>/dev/null | egrep "Disk /|/dev/" | sed "s#^/dev/#Part /dev/#" | awk '{print $2}' | sed 's/://' | xargs -n1 -IX sudo sh -c "hexdump -v -s 0x80 -n 2 -e '2/1 \"%x\" \"\\n\"' X | xargs -n1 -IY sh -c \"case \"Y\" in '48b4') echo X: GRUB 2 v1.96 ;; 'aa75' | '5272') echo X: GRUB Legacy ;; '7c3c') echo X: GRUB 2 v1.97 or higher ;; *) echo X: No GRUB Y ;; esac\""

ok perfect it works!

this is the output....

Code: Select all: /dev/sdb: GRUB 2 v1.97 or higher /dev/sdb1: No GRUB 00 /dev/sdb2: No GRUB 00

is it possible to move grub to sdb1???

thx!

ITALIAN: OK funziona e questo e' l'output:

Code: Select all: /dev/sdb: GRUB 2 v1.97 or higher /dev/sdb1: No GRUB 00 /dev/sdb2: No GRUB 00

e' possibile spostare grub su sdb1???

I thought to tdo in this way but at the second command it gives error ....pensavo di far cosi' ma al secondo comando mi da errore....

Code: Select all: mount /dev/sdb7 /mnt mount /dev/sdb7 /mnt/boot grub-install --root-directory=/mnt/ /dev/sdb7

grazie

Hi!
Your Grub is installed in the MBR of sdb; to answer your question we should know why you want to install Grub in the root(?) partition of sdb; what about sda? Which operating systems are installed?
Please post the output of Terminal

Code: Select all: sudo fdisk -l

> l like list
or

Code: Select all: sudo parted -l print

Hi!
Please first answer:
1. You have Gnome or KDE or?
2. Running my first command to find GRUB, you had plugged in any USB drive or USB flash?
3. As I asked before: what operating systems are installed?
4. You have one internal hard disk?
5. Please post the output of Terminal / Konsole as root

Code: Select all: blkid

hello
here the answers:

1) KDE
2) no usb or flash pen.....the "particular thing that is connected is an internal flash card reader
3-4) in one disk linux...i' have also another sata disk with windows but now i have disconnected because it is broken and i have to change it

by **harmon** » Sun May 01, 2011 9:58

Hi!
1. Please post the output of Konsole

Code: Select all: su -

password

Code: Select all: blkid

2. What do you see after having booted your computer? Grub menu 1.98?
3. You are able to start to your Linux KDE desktop, I suppose - where is the problem?

because some other bootloader to boot linux need that grub is not installed in the mbr but in the linux partittion....

anyway....typing the command u suggested, this is the output:

Code: Select all: /dev/mapper/vg_mypc-lv_swap: UUID="ebee74e7-9599-4784-a17a-38050c17a7f5" TYPE="swap" /dev/mapper/vg_mypc-lv_root: UUID="e61b54fb-f284-47f7-8d5f-35dbcf3e5a5e" TYPE="ext4" /dev/mapper/vg_mypc-lv_home: UUID="05f79a55-df0c-4e7f-93de-7c68b975fa2d" TYPE="ext4" /dev/sda1: UUID="304a66db-d030-4c41-97b0-583e319e396a" TYPE="ext4" /dev/sda2: UUID="vxYhOJ-fw1s-0z3u-umbg-cq7f-PQr4-IY5AlN" TYPE="LVM2_member"

Hi!
1. To install Grub in a root partition after having installed Linux with Grub in the MBR - I've never heard that someone succeeded; I tried it too and got - after a warning - the message "okay", but no luck.
Installing Grub from a live medium into the MBR is no problem.
So: What I want to say: it seems that you have to make a fresh Linux installation choosing as boot loader device the root partition.
Or: Anybody succeeded to install Grub1.98 or higher in the PBR (root partition) after having installed Linux with no Grub or Grub in MBR?
2. I cannot give you further help, because I don't have enough information (which OS on which device/ partition).
