help required in installing 64bit os from 32bit

[osmington]

have an acer aspire 6920g.
i'm fairly sure that it is capeable of running a 64bit os even though it's running a 32bit at the moment.
i cannot install a 64bit disc from the current os directly or from the hard drive when it has been re-formatted.
can anyone come up with a solution please ?

here are the specs :
processor - intel mobile core 2 duo t5750
code name - merom
package - socket p (478)
technology - 65nm
core vid - 1.063 v
spec - 2.00 ghz
instructions - mmx, sse, sse2, sse3, em64t (which on test say its 64bit enabled)

motherboard - acer aspire 6920
chipset - intel pm965 rev. - c0
southbridge - intel 82801hbm (ich8-me)
bios - acer
version - v1.07

You will not be able to do that, you must boot straight into the 64-bit setup.exe (it's also likely that you'll loose data unless you have a partitioned or external hard drive to dual boot from so back your data up).
