[linuxd]

oh I am in deep trouble. I was using ubuntu 8.10, then i upgrade it to 9.04.
Everything works perfectly.
But today my little brother tell to install windows to play games.
I have many partitions in my hard drive, some are NTFS,
So i insert windows XP boot disc and start booting.
after format a partition,
it copying files, and then restart (as usual)
But the problem is when restart no screen says press any key to boot from CD
and the booting process start from the first, agan i command to format partition, again copying files ..again restart and again start from the first
After eject the CD, my BIOS says no boot device..
I check my BIOS setting,, everythings is fine.. I change boot device Order but nothing happens.
Now i browse this page from ubuntu 8.10 live cd.
By the way I check my file system via live CD,and find that,previous ubuntu version is stay cool.
Now i wanna get my ubuntu back.. I dont want to install it again,coz then I have to update 300+ items,and after that i could upgrade to 9.04..(that is tough 4 me in my poor net connection!!)
I think i have a problem in grub-loader but i dont have a knowledge about it..
plz help ...........

Execute this in Terminal of LiveCD :

sudo grub

You will get a grub prompt, grub>
Execute this:

find /boot/grub/stage1

If you get "Error 15: File not found", try the following:

find /grub/stage1

Using this information, set the root device (fill in X,Y with whatever the find command returned):

root (hdX,Y)
setup (hd0)
quit

Reboot machine.

[linuxd]

grub> find /boot/grub/stage1
(hd0,5)

grub> root (hd0,5)

grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p (hd0,5)/boot/grub/stage2
/boot/grub/menu.lst"... succeeded
Done.


after enter command quit it shows

Probing devices to guess BIOS drives. This may take a long time.

Did you change Partition Structure after Linux installation?

[linuxd]

no.. everything is unchanged..
last night i browsed all the web and i found that
it can be a bug of GParted in 9.04.
One website give solution that, download and burn GParted in disc and boot GPArted can solved the problem.
(by the way,last moment, i try install ubuntu, but in the partition step, it also show whole hard drive as unallocated space in both guided and manual process)
so i quit the installation, coz I dont wanna lose my entire data!!
please give me a solution yar....

Have you changed any option in BIOS? Reset BIOS settings to default.
Is there any chance of Windows Boot Virus infection?
Try SuperGRUB CD/USB/Floppy to re-install GRUB. Download options for each are avilable at right side of its homepage. I prefer USB Image because you won't have to burn CD for that.

I had a similar problem where it was my BIOS just screwing around with drive order that seemed to kill Grub. A few times later and it just fixed itself, either that or me playing around with physically swapping disks arond on different cables.
