Re: [Bug-grub] Not able to boot

[Vidya Kulkarni]

Jochen,

      I tried all commands with the following response:


1.   root (hd0,0)

    File system is fat, partition type 0xc

2.  chainloader+1

    Error: Unrecognized command

3.   boot

    Error : Cannot boot without kernel loaded


4.  find /vmlinuz

     It tries to read something from hard disk but there is no response

5.  find /boot/vmlinuz

     same response as above

6.  find /zImage

    same response as above

7.   geometry (hd0)

     drive 0x80: C/H/S = 1024/240/63, The number of sectors = 23572080, LBA 
Partition num : 0, File System type is fat,
     partion type is 0xc

     Error partition table invalid or corrupt

    I do not know exactly what has happened. It seems that partition table
    got corrupted. Please tell me what can be done about it.

Thank you very much for the help. Awaiting further help.
