I am supposed to fix a laptop in which the hard disk was recently formatted. It contained Windows 7 before. I am trying a fresh install of ubuntu 12.04 from a bootable USB, but haven't been able to go past the maintenance shell. In the maintenance shell, I tried out the following:
root@ubuntu:~# ntfsfix -b -d /dev/sda Failed to determine whether /dev/sda is mounted: No such file or directory Mounting volume... NTFS signature is missing. FAILED Attempting to correct errors... NTFS signature is missing/ FAILED Failed to startup volume: Invalid argument NTFS signature is missing. Trying the alternate boot sector Unrecoverable error Volume is corrupt. You should run chkdsk
The trouble may be that there aren't permissions to write on the ntfs partition. The partition might not be corrupt. When I check the filesystem, I get this:
root@ubuntu:~# fsck /dev/sda fsck from util-linux 2.20.1 ext2fs_check_if_mount: Can't check if mounted due to missing mtab file while determining whether /dev/sda is mounted. Bad magic number in super-block The superblock could not be read or does not describe a correct ext2 filesystem.
So, it must be an ntfs file system. that's why I tried ntfsfix but that didn't work. The hard disk is not partitioned. When I run
it shows /dev/sda (~500 GB) and /dev/sdb (boot recovery) . I have been trying to run
badblocks -v /dev/sda
But, suddenly the laptop just reboots and I don't even get to the maintenance shell stage. I select "Install ubuntu" and it gets stuck at the wait screen forever. Please help!
