Windows 7 disappeared in list of Grub while loading
- by Riyad A.
Installed Ubuntu 12.04 alongside the Windows 7 two weeks ago. Initially haven't any issues with that. day ago installed updates on Ubuntu and after restarting the system found the absence of Win7 in Grub list. Before the HDD has been partitioned on two volumes Disk C and Work Disk(don't remember the name). When doing the fdisk -l:
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0xa93031e0
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 408833842 204415897+ 7 HPFS/NTFS/exFAT

/dev/sda3 408834046 488386559 39776257 5 Extended
Partition 3 does not start on physical sector boundary.

Partition table entries are not in disk order

49 heads, 48 sectors/track, 3292 cylinders, total 7744512 sectors
Units = sectors of 1 * 512 = 512 bytes

Disk identifier: 0x00000000

/dev/mmcblk0p1 8192 7744511 3868160 b W95 FAT32
When sudo mount /dev/sda ~/1 -o offset [488386560*512] - opens and mounts WORK disk.
Need help: how to See and mount disk C.
how to see and adjust the Grub to appear both systems in Grub menu when loading?
