I accidentally formatted my hard disk containing ubuntu partition. I also run a windows vista. I formatted my 2nd hdd, the ubuntu partition. after I reboot I'm getting a message

error:no such device:2fe5264c-df46-4507-9eee-8a7f1335c846
grub rescue>"

I also tried to boot from my liveCD by changing the bios menu.

I tried the following settings in the bios

  • 1st boot - cdrom \ usb
  • 2nd boot - hdd \ cdrom \disabled
  • 3rd boot - usb \ hdd \disabled Still the same error is repeated. I also tried the following commands

    grub rescue> ls (hd0) (hd0,msdos1) (hd1) (hd1,msdos1) (fd0) grub rescue> ls (hd0)/boot in all possible combinations

I get the error error: unknown filesystem

Except for the command ls (fd0)\boot I get error : fd0 read error. I totally formatted my 2nd hdd. My system is Desktop, P4, hdd1 80GiB (vista), hdd2 30GiB (ubuntu)(formatted) , 1GiB DDR RAM. now I cannot even load my Windows OS.

I also tried to install windows 8 using USB and liveCD, but it didn't work. I can't even read my cd or usb drives.

Please someone help me.

In case we had not written to the accidentally formatted drive we are able to fully recover partitions with
