Cannot Boot Vista

[Hesham]

I've installed fedora 10 after installing vista on my hard drive. I see the boot menu on the pc start up but when selecting to boot vista the pc restarts again.

I've tried to fix that and made the following changes to grub.conf but I have the following output:

Error 12 : Invalid device requested
Press any key to continue...

See I did a good job :s

Anyway that's my hdd layout:

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x46cc46cb

   Device Boot      Start         End      Blocks   Id  System

/dev/sda8           17032       19289    18137353+  83  Linux

Partition table entries are not in disk order

And that's my grub.conf:

default=0
timeout=5
splashimage=(hd0,6)/boot/grub/splash.xpm.gz
hiddenmenu

	initrd /boot/initrd-2.6.27.7-134.fc10.i686.img

title Vista

Please note that I'm linux newbie so if anyone will try to help me please give me simple description of the solution.

Thanks in advance.
