KUbuntu not booting after install

[samitekken]

Hi Everybody.
I'm a linux nubie, i have installed Kubuntu 11.10 alongside windows 7
After installation, Kubuntu doesn't boot, only windows 7.
I installed Ubuntu in a separate partition, and the install went through correctly
when the installation was done, i removed the liveCd and "enter", then only windows 7 boot.

Thanks for Help.

it sounds like when you installed Kubuntu Grub (the boot loader) got installed to the installation partition instead of the MBR .
when you were at the part of the installation ware you pick the partition to install Kubuntu to at the bottom is a menu for ware to install grub to ..........if lets say you were installing to a single HD it would have been somthing like /sda2 assuming win7 is in /sda1 you would have wanted to have grub installed to /sda

so now we will nead to know how you installed ........did you prepartition the HD or did you let the installer do this?
if you can boot the live cd to a desktop and copy and past the output of

sudo fdisk -l

hear so we can see the HD's layout and advise how to proced.

I did the partition sda2 for swap, sda7 for ubuntu, and also chose sda7 for grub file i guess.
and just to let you know, i installed kubuntu 10.04 LTS with the same steps i did 11.10, and it worked fine

So
I followed the steps. the code : sudo fdisk -l
it showed the partitions labelled "Linux" , i mean for swap partition and partition where i installed ubuntu,

and when i checked the grub file, i got this :

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

Is There Something Else I Could Do ?

Go into the live CD and mount your Kubuntu somewhere and chroot into it.

sudo mount /dev/sda7 /mnt/kubuntu
sudo chroot /dev/kubuntu

From there you can update and install grub to the MBR of the disk

update-grub
grub-install "/dev/sda"

That should get grub installed to the MBR. It should let you boot into Windows 7 without any trouble.
