Backtrack 4 R1 Installation help

[compfellows]

Hello,
I downloaded BT4 R1 and verified the md5 hash.
When I install BT, everything goes fine until the progress bar hits 43% after that, the installation just stops and the live DVD stops running. Please help me!

Try burning another DVD at low speed and try testing the dvd on another PC on another PC.

I've tried it twice in 2 DvDs. In the beginning, both the dvds stopped at 22%. I changed some bios settings and removed the floppy disk drive. After that, both dvds go till 43%. Does the installation check some hardware at 43% which has caused this error? Please help me!

Define "stopped at 43%", what error does it give you, also have you tried running it in a VMware/VBox and installing it from there ?

At 43%, it doesn't show any error but the disk stops running (spinning).
I haven't tried installing using VMware

I have problems using VMware. I get an error called "Physical memory not available". I want help with the Live DVD. Are there any drives I need to remove?
As I said, my BT install stopped at 22% when I had enabled my floppy drive. But after disabling the floppy drive from bios, the installer moved till 43%. I just want someone to tell me what to do now? Please help me! I am not new to linux. I've been using debian for a long time and now I want to try BT to protect my website. Please help!
