I need to reinstall my GRUB since I cannot boot windows 8 anymore (something happened with my installation of Ubuntu). I want to follow this advice - Boot error > no such device: grub rescue in order to re-install the grub but I made the stupid mistake of allocating half of the size of the partition to windows and half to Ubuntu lol. So now I need to know on which partition I have Linux could someone help me out ? Thanks. Here is the partition list

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *        2048      718847      358400    7  HPFS/NTFS/exFAT
/dev/sda2          718848  1025779711   512530432    7  HPFS/NTFS/exFAT
/dev/sda3      1025779712  1851121663   412670976    7  HPFS/NTFS/exFAT
/dev/sda4      1851121664  1953521663    51200000    f  W95 Ext'd (LBA)
/dev/sda5      1851123712  1953521663    51198976    7  HPFS/NTFS/exFAT

sorry, I had a crash Here is another list I get :

   Device Boot      Start         End      Blocks   Id  System

/dev/sdb1            2048   923381759   461689856    7  HPFS/NTFS/exFAT
/dev/sdb2       923381760  1438451711   257534976    7  HPFS/NTFS/exFAT
/dev/sdb3      1438453758  1953523711   257534977    5  Extended

Partition 3 does not start on physical sector boundary.

/dev/sdb5      1920051200  1953523711    16736256   82  Linux swap / Solaris

According to your partition list, there is NO Ubuntu partition. –  Mitch Oct 1 '13 at 7:29
    
well I installed it alongside windows but now I can't boot windows. It says error unknown device - some numbers then grub rescue. Can you help me please ? –  yamakoto Oct 1 '13 at 7:30

Boot the Live Sytem from your installation medium. Mount the partitions and search for your Ubuntu (should be easy to find, directories like etc, home, usr, root in the root directory of the partition)

Yea but it gives me an error when I try to do that : Error mounting : mount exited with exit code 14 : windows is hibernated. refused to mount. --- I installed ubuntu alongside windows –  yamakoto Oct 1 '13 at 7:17
    
The problem is told in the error: Windows is hibernated. That's why you can't boot into Ubuntu. –  the_Seppi Oct 1 '13 at 7:31
