Unhappy How to rewrite MBR???


Hi,

I have just tried to install Fedora 11 from the Live CD. I think it over-wrote my MBR, as now when I boot, I get "Non-system disk or disk error/ replace and strike any key when ready".

How do I reinstall a bootable MBR. Can grub do this from the live CD?

Laptop Specs:
HP Elitebook 2530p
2048 MB Ram
Intel Core Duo CPU L9400 1.86Ghz
BIOS: INTEL 1659

NB. I am trying to dual boot Windows and Fedora. Can't access Windows. Ideally I would like to get access to both (much as I love Linux , pragmaticly, either will do to start with...

Regards, Mark

Unhappy how to find my way around partition table?

Hi,

I am able to load the Fedora 11 live cd, and from there i can access the command grub-install, but I am a newbie and know v little about finding my way around the partitions, let alone the complex lvm structure the installer has set up. how do i find out what device to install grub to?

Hi mark,
Did you complete the installation?

As suggested give the output of
Code:
su
fdisk -l
When you know your root partition say /dev/sda3 then as root do
Code:
mkdir /tmp/fed
mount /dev/sda3 /tmp/fed
chroot /tmp/fed
grub-install /dev/sda
If your installation was successful then when you reboot you would be able to boot.

Btw, have you got seperate /boot? I'm not updated but last time I tried Fedora11, it wanted a seperate /boot with ext3 filesystem and the / with ext4.
