[ubuntu-us-mn] Fwd: fdisk -l

[Thomas Rieff]

I was updating some things on my laptop and it would not bring a login screen back up.
I can get back into it with a livecd. Did a fdisk -l and got the following. Tried to re-install grub but no luck.
My concern is the partitions sda2 and sda5 cover the same area in the hard drive.
Any ideas???
