Hello jendim,

Well, to summarize your fdisk:

You have two drives (40GB and 1.5GB). The 40GB drive has three primary partitions and one extended partition that is completely filled with a single logical partition. All 4,865 cylinders of the drive are accounted for. The fdisk device names are not in disk order. Of the four partitions on this drive, two are native Linux and two are LVM physical volumes. The two native partitions are both probably boot partitions because of their small size. The 1.5GB drive contains a single primary FAT32 partition that completely fills the drive. It may be a Windows OS but may only be storage because of its small size.

Summary of the grub.conf:

The grub.conf is the F8 grub.conf, and it does not contain a menu entry for another Fedora system. It reveals that the F8 boot partition is probably /dev/sda2 (hd0,1). The F8 system is using Logical Volume Management, so one of the LVM PVs belongs to F8. The "Other" menu entry may be for a Windows OS on the 1.5GB drive, and if so, it probably doesn't boot as written because it is on a "non-first" drive and would likely require map commands in the grub.conf to boot.

What I would do:

1. Write an entry for FC6 in the F8 grub.conf.
2. Edit the "Other" section of the F8 grub.conf to add map commands to boot the Windows system. Or, if it is merely a storage partition, remove that section entirely.

HOWTO add an entry to the F8 grub.conf for FC6:

1. Since it is known from the the grub.conf that (hd0,1) contains the boot directory for F8, then the only only other possible partition that could contain the FC6 boot directory is (hd0,0).
   
   
2. Open the F8 grub.conf for editing like this...

   su
   gedit /boot/grub/grub.conf

   Add a section for FC6 like this...

   title FC6
   configfile (hd0,0)/grub/grub.conf

   Save the grub.conf. Reboot and try booting FC6 from the F8 menu.

HOWTO edit the "Other" section of the F8 grub.conf:

1. If that FAT32 partition really is a Windows OS, then change that section of the F8 grub.conf as follows. If it is merely a small storage partition, then skip what follows (perhaps just remove that entire section from the menu).

   title Windows
   rootnoverify (hd1,0)
   map (hd0) (hd1)
   map (hd1) (hd0)
   chainloader +1

2. Save the grub.conf. Reboot and try to boot the Windows system from the F8 menu.

P.S.: No promises. I guessed at all of this. There are plenty of reasons for some or all of this not to work. If that happens, return and tell what went wrong.

Thanks again i'm so lucky to be part of this community. I will give the result tomorrow i mean my unit is in my house.

Thanks,
