Edit: I just read Intel's Doc about your T5500 here, it doesn't support VT-x, thus you won't be able to virtualize 64bit guest OS. You can virtualize 32bit guest OS though...
Now that explains the mystery. Thanks for the findings.
Hi, I'm a total novice to Ubuntu who is reading this thread because I was intrigued by a mention in PCWorld that one could run Portable Ubuntu Remix "as an app within Windows". Portable Ubuntu For Windows http://www.progmic.com/2009/09/porta...-in-windows-7/ However it would not work for me stopping with a fatal error about cygwin. So I was searching this forum to look for answers and stumbled on this thread. Unlike the OP, what to do remains a mystery to me ..... I am running Windows 7 Home Premium 64 bit. I have 6 G of ram but my processor is a "Intel Core2 Duo P7450" which I believe does not have the built in virtualization capability and as noted my Windows 7 is not Professional. a) Can I still run another OS in a virtual box (XP or Ubuntu)? b) How? c) In view of the problems discussed in this thread, will it be able to run Ubuntu 32? (Maybe the 32/64 conflict was my problem in running the portable Ubuntu as a Windows 7 app, even though I carefully followed the instructions in http://www.progmic.com/2009/09/porta...-in-windows-7/ Would appreciate any help. Thanks.

Dinesh did you ever get this running? The fix is in the BIOS. I have older laptops and the setting was there for me. PM me if you need a hand still, yes a little late but hey, worth asking. I know many people are struggling.
