[mdlug] Mythbuntu CD would not boot on a X64 system

[R KANNAN]

Never mind. I could boot with the install CD after using kernel option
'nomodeset'.

I could create partitions as needed and install but the MBR did not get
updated. The system now boots up in Windows 7 (with reduced  disk space).
Maybe HP has a security option whereby it does not allow MBR to be updated.
Need to look into it.
