I have a Dell XPS720 that came with Vista Home Premium 32bit and 4 GB of Ram. Recently I installed Windows7 Ultimate 64bit on separate Disk and purchased 4 more GB of Ram.
Now using Windows7 all the time but when I try to install more than 4 GB of Ram I can not boot up into Windows7. ( when it starts to boot into Windows7 it asks to start normally or repair...... with normal it quits and restarts and with repair it does nothing and i have to force quit) I can boot into Vista 32bit.
My Question is how can I get Windows7 to use 8 GB of Ram without starting over reinstalling all the programs and settings.
I have been told I should remove the Vista disk and the Windows7 disk and do a single boot clean install of Windows7 and then I would be able use the 8 GB of Ram and the system would be more stable.
But then I would have hours and hours of reinstalling programs and settings.
I found out I can not just delete the Vista Disk because then I get a NTLDR
