Re: Computer won't boot to 9.10; No Grub Menu
It could be that GRUB wasn't installed in the correct hard disk or you might have a CMOS setting (BIOS) which prevents any programs writing to your first hard disk's MBR.
You should be able to try again to install GRUB 2 to MBR using your Ubuntu Karmic Koala 'Desktop' Live/Install CD.
Try booting with your Live CD and then mount your hard disk installed Ubuntu operating system.
Take a look in /media to see what the name of the mount point is or ls /media,
You should get a nice user-friendly name for the mount point if you set a file system label, otherwise you might get a file system UUID number which can be rather long and cumbersome.
You can set a file system label by right-clicking on your partition in GParted, for example I simply call mine KARMIC.
Regardless of whether you set a label for your file system or you're happy to stick with the UUID number, open a terminal and run the following command,
Code:
sudo grub-setup -d /media/KARMIC/boot/grub /dev/sda
Where /media/KARMIC is the mount point for your Ubuntu file system, otherwise it could be some other name or a UUID number. Feel free to replace as appropriate.
If it complains about not being able to open /boot/grub/device.map, you might need to hold it's hand and specify the path to the device.map file with the -m option, as follows,
Code:
sudo grub-setup -d /media/KARMIC/boot/grub -m /media/KARMIC/boot/grub/device.map /dev/sda
If it still doesn't work try looking in your CMOS and disabling any MBR write-protect feature you may have left enabled, it may also be called something like 'boot sector antivirus' or some other name.
If your computer has more than one disk you might need to change the '/dev/sda' part of the command to /dev/sdb or something else.
