hello dear friends

code:

update-grub  generating grub.cfg ...  found linux image: /boot/vmlinuz-2.6.31-16-generic-pae  found initrd image: /boot/initrd.img-2.6.31-16-generic-pae  grub-probe: error: no mapping exists `sil_aiaiafafaccb5'  grub-probe: error: no mapping exists `sil_aiaiafafaccb5'  found linux image: /boot/vmlinuz-2.6.31-14-generic-pae  found initrd image: /boot/initrd.img-2.6.31-14-generic-pae  grub-probe: error: no mapping exists `sil_aiaiafafaccb5'  grub-probe: error: no mapping exists `sil_aiaiafafaccb5'  found memtest86+ image: /memtest86+.bin  done

fdisk give me :

code:

   device boot      start         end      blocks   id  system  /dev/sda1   *           1       60770   488134993+  8e  linux lvm  /dev/sda2           60771       60801      249007+   5  extended  /dev/sda5           60771       60801      248976   83  linux    disk /dev/sdb: 500.1 gb, 500107862016 bytes  255 heads, 63 sectors/track, 60801 cylinders  units = cylinders of 16065 * 512 = 8225280 bytes  disk identifier: 0x0007d07d       device boot      start         end      blocks   id  system  /dev/sdb1               1        7392    59376208+  83  linux

the system installed on the /dev/sda

i've lost several hours search similar issues , found nothing similar (issue dual booting, encrypted home- don't have etc etc)

have met problem ?

forgive me because i'm not familiar grub2, output of:

code:

cat /boot/grub/device.map

mine looks this:

code:

(hd0)	/dev/sda

maybe make backup of yours:

code:

sudo cp /boot/grub/device.map{,.backup}

then edit yours mine , run "sudo update-grub" again. don't believe cause server stop booting if worst comes worse restore old file using live disk.
