I have an Asus laptop that came with Windows 8 installed on it. I bought it about a year ago, and installed Ubuntu on it, in addition to Windows, and have been ahppily using it since then. A coupl;e of weeks agao, I did an apt-get dist-upgrade, and a bunch of stuff was updated. Shortly after that I changed the physical location of the machine, and neeeded to change the networking settings. I edited /etc/network/intrfaces, and tried to do a "service restart networking". I lost X, and could not get to a TTY, so I hard shut the machine down with the power switch.
After that, i could not boot into UBUNTU. I can boot imto Windows. I searched around and built a found boo-repair. I booted off of a 12.04 desktp 64 bit DVD taht I had a ran it. The results are on http:/paste.ubuntu.com/6575927/ but I still cannot boot into Ubuntu.
At this point, I have created a 13.10 64 bit desktop bootable USB stick. and have booted ino that. I think I have issues with my partion table. If I try to fsck my UBUNTU partion, while booted from the live USB stick, fack complains, and says something about a zeror length partiton.
When I run sfdik it says:
buntu@ubuntu:~/debug$ sudo sfdisk --no-reread -d /dev/sda > sfdisk.out
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util sfdisk doesn't support GPT. Use GNU Parted.
and it's output is:
# partition table of /dev/sda
/dev/sda1 : start= 1, size=976773167, Id=ee
/dev/sda2 : start= 0, size= 0, Id= 0
/dev/sda3 : start= 0, size= 0, Id= 0
/dev/sda4 : start= 0, size= 0, Id= 0
I have atached a screenshot of gparted's view of things.
I have about a years worth of work into this machine at this point, and i would greatly apprecuate any advice as to how ro fix this problem, or at least get to the point that I can mount the UBUNTU partion and save my configurations and data.
BTW, I have tried booting in both UEFI mode, and what Asus calls CSM mode, if that helps. I beleive I originally installed in CSM mode.
