I am trying to update a dual boot labtop Windows 8.1 and CentOS . I may have an issue with the bootsector

[Christian Weithøft]

As the system fails to install correctly during change from CentOS to Ubuntu GNOME I can't give much information on the exact version. I have fetched the lastes Ubuntu GNOME rel 14.04 Beta 1. from dayli build. (2014-03-01)

I install from a USB pen (4 GB) that seems to be OK.

GRUB loader does not get installed. I may need to clean up boot loaders. I have Window and CentOS loaders installed.

CentOS won't boot. Fails with kernel panik during boot process.
