    I have a problem.
    I had Windows 7 on my laptop already, and I installed Windows XP on another drive, and yes it all went smoothly.
    Then when I had just done the easyBCD, and restarted and tried to load my Windows 7. If t wouldn't allow me, and I have been searching for an answer for a while, so I'm here now posting.

    I assume you mean you installed XP on another partition?

    Please post a screenshot of Disk Management window.

    Hi guys,some help needed please.

    I bought a new hard drive so I can duel boot my pc, xp and win 7. I also bought 4gig of ram to replace the 2gig I had in there. So before doing anything else I took out the old ram and put in the two sticks of new (in duel ram mode.) Booted the pc up and the post screen shows 4gig of ram in duel mode. Xp only shows 3.50 because it's only 32 bit as expected. I've now put in the new hard drive, formatted it and installed 32 bit win 7, but that only shows 3.50 of ram as well. So am I wrong in thinking that both 32 and 64 bit win 7 should show the full 4gig like Vista.

    If win 7 32 bit is not able to show 4gig is it to late to uninstall it and put 64 bit on.

    Hello Ash,

    Yes, you can format the 32-bit Windows 7 and install the 64-bit Windows 7 if you like, and if your computer has a 64-bit CPU and 64-bit driver versions for all of your devices.

    Afterwards, you may need to remove the old 32-bit Windows 7 from the Boot Manager list as at startup though from within the new 64-bit Windows 7 installation.

    Hi Brink, thanks for the quick reply.

    Just checked with a friend who's done the same as me and he says his 32 bit win 7 is showing the full 4gig. Can you think of any reason why mine isn't.

    I'm not sure why. Did you do a clean install of Windows 7?

    Could be because of the RAm he has in his laptop/desktop...

    Some RAM report less because of the quality of RAM or some settings in the BIOS that is limiting it

    Hi Brink, yes it was a clean install on a new drive.

    Hi Zidane24, yes you could be right. but I wouldn't know were to start looking or what I was doing to be honest. I'm just afraid that if I take off 32 bit win 7 and put 64 bit win 7 on, the ram might still only show 3.50 gig.

    As for the quality of the ram, it's Corsair XMS2 and it's in a desk top pc.

    Thanks anyway guys. I'll give the store were I bought if from a call tomorrow.

    Do you by chance have a integrated graphics chip?

    If you do, then the missing 512MB may be allocated to it in the BIOS thus only giving you 3.5 GB available.

    It may sound silly but what have you got to lose by installing the 64-bit W 7 to see what it'll report, if you don't like the outcome put the 32-bit back on.
