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

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 :-(
