Never mind. I could boot with the install CD after using kernel option 'nomodeset'.<br><br>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 :-(<br><br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Hi,<br>
<br>
I have a new HP desktop with Intel i7-2660 processor and windows 7.<br>
<br>
I downloaded an burned a Mythbuntu 12.04 X64 iso. I also checked the<br>
md5sum on the downloaded iso and found it matched with the published value.<br>
<br>
When I tried boot the system up with the CD. It flashed the message<br>
<br>
Error: "Prefix is not set"<br>
<br>
but came with the following options menu<br>
<br>
Try Mythbuntu without installing<br>
Install Mythbuntu<br>
Check disk for defects<br>
<br>
When I tried either the first or second, the drive spins for a while, then<br>
it starts making sounds as if it is reading the disk and two horizontal<br>
lines of green/blue dots appears on the screen and the drive goes silent.<br>
<br>
I tried burning the image on another CD but with the same results. Should I<br>
be changing some options or use grub on the command line to debug?<br>
<br>
Thanks<br>
<br>
