Unable to Find Windows in dual boot System


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,

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x97be5b6a

Device Boot Start End Blocks Id System
/dev/sda1 * 1 2550 20482843+ c W95 FAT32 (LBA)
/dev/sda2 2551 9728 57657285 f W95 Ext'd (LBA)
/dev/sda5 2551 5100 20482843+ b W95 FAT32

/dev/sda7 5101 7520 19433472 83 Linux
/dev/sda8 7520 7650 1046528 82 Linux swap / Solaris

Partition table entries are not in disk order



i got some thing like this when saw grub.conf

"# grub.conf generated by anaconda
#

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

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.
