    my windows is in /dev/hdc5. Actually while re-installing linux i deleted /dev/hdc3 and /dev/hdc4 and merged and aded them to /dev/hd7. Now i am not able to boot into windows i tried changing rootnoverify (hd0,2) to (hd0,1,2...all possible options but in vain. What is the suggested solution so that i am able to boot to windows?

    Windows OS has been installed in a Logical Partition and it doesn't boot up in most of machines.
    Where did you install Linux earlier? Was dual boot working earlier?
    It is amazing what you can accomplish if you do not care who gets the credit.

    As 'devils casper' posted it is not a good idea to have XP on a logical volume. You will not be able to do any type of XP install, clean or repair. Your best bet would be to use a program to remove XP back to a primary partition. "testdisk" will convert it back.

    The correct boot title would be: 'as partitions are currently'
    rootnoverify (hd0,4)
    chainloader +1

    If you current XP will start to boot but fails with 'missing /windows/hal.dll' then the boot.ini file is wrong, XP will be seen on partition #2.

    Thanks for your reply. XP does not boot at all. Is it any other way you may suggest that i can get things working, I have never used testdisk.

    Have you edited your menu.lst ?
    rootnoverify (hd0,4)
    chainloader +1

    Would still suggest converting XP back to a primary partition with testdisk. Doing so will put the swap partition on sdc5 vice sda6. Not sure just what partition XP would be put, would have to have a new look at fdisk -l after running testdisk.

    go there to read the How -TO use first. testdisk may be in your linux repositories , can download from site above only if you know how, or can get a live cd with testdisk and other programs at
