Hello All,

I'm back with new problem recently i have installed CentOs 6.2 in my system but when installation get completed i was unable to see my windows partition in "grub.conf" as i was trying to make my system dual but failed i'm able to get all my partition through "fdisk -l" command.

my fdisk command shows some thing like this,

Help me guys..

I'm able to see windows files in /dev/sda1 * 1 2550 20482843+ c W95 FAT32 (LBA) this partition.

Try putting/adding the following into your grub.conf;

title Windows
rootnoverify (hd0,0)
makeactive
chainloader +1

Dear fatmac,

Thanks alot the issue is resolved but one more thing that i wanted to know that why the grub loader didn't add windows entry to grub.conf file is there any installation mistake which i did ?

Grub doesn't care - Anaconda (the Redhat/CentOS installer) tries to build entries for you.
But IIRC only for NTFS, not Windoze systems installed in FAT partitions.

You did nothing wrong during the CentOS install.

Thanks alot you all that was really informative.
