Thread: invalid partition table-wrong signature e1f5

hi guys,
noob ubuntu user, pc fine until yesterday , says have invalid partition table, using live cd ubuntu 12.04 since hdd missing,


looking online solutions , got w sudo fdisk -lu comand

code:

ubuntu@ubuntu:~$ sudo fdisk -lu warning: ignoring data in partition table 5 warning: ignoring data in partition table 5 warning: ignoring data in partition table 5 warning: invalid flag 0xe1f5 of partition table 5 corrected w(rite)  disk /dev/sda: 400.1 gb, 400088457216 bytes 240 heads, 63 sectors/track, 51681 cylinders, total 781422768 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0x29c7d638     device boot      start         end      blocks   id  system /dev/sda1   *          63    25189919    12594928+  83  linux /dev/sda2        25189920   614416319   294613200    f  w95 ext'd (lba) /dev/sda3       614416320   655376399    20480040    7  hpfs/ntfs/exfat /dev/sda4       655376400   781401599    63012600    7  hpfs/ntfs/exfat /dev/sda5   ?  1287063685   941516022  1974709817   b9  unknown  disk /dev/sdb: 3926 mb, 3926949888 bytes 16 heads, 16 sectors/track, 29960 cylinders, total 7669824 sectors units = sectors of 1 * 512 = 512 bytes sector size (logical/physical): 512 bytes / 512 bytes i/o size (minimum/optimal): 512 bytes / 512 bytes disk identifier: 0xc3072e18     device boot      start         end      blocks   id  system /dev/sdb1   *        8064     7669823     3830880    c  w95 fat32 (lba)

i think red part problem dont know how 2 fix it, have 2 missing partitions , sda2 (win7) way bigger remember in space there should 3 partitions , not win7

it says running fdisk , doing write correct invalid entry, not sure partition stil wrong. size not valid. swap inside extended partition , should have same size , sector counts extended partition?

first backup partition table,
sudo sfdisk -d /dev/sda > parts_sda.txt


can try fdisk.
fixes issues , worth trying:
following :
fdisk /dev/sda
use option : x (expert mode)
use option : f (fix partition order)
use option : r (return)
use option : p (to print)
use option : v verify partition
if ok
can do
option : w ( write table disk)
option : q quit
else if not ok
post output of option p , v

have sucess fixparts.
