Cant boot from cd, or flash drive windows 7 installation after restart

Hello, im currently running Windows 7 Ultimate 32bit on my laptop.

I wanna install windows 7 home premium 64bit in clean install, i have 2 installation DVDs of win 7 home 64bit, one is older, another is lil newer build (more updates in it), but none of them want boot up after laptop restarts. I also did try make bootable flash drive following all the rules, it also wont boot up from flash drive. I checked BIOS settings, i managed to boot from DVD, USB in force, still no luck. Maybe its something wrong with the DVD? files on the installation disk looks like this:



To bad i cant run setup.exe cause im running 32bit OS.

I wanna switch to 64bit cause im thinking my system will work faster in that way, maybe im wrong?

CPU: Intel T6600 Core 2 Duo 2.2Ghz
RAM: 3GB DDR2

1) I've run both 64 bit and 32 bit win7 on a 3 gb system similar to yours and have not experienced any speed increase in 64 bit. 64 bit windows lets you take advantage of memory greater than 4 gb in case you have it, thats all.

2) You said one dvd is a newer build so I presume these are home made dvds, perhaps with updates slipstreamed? Its possible theres something wrong with them. You can try using the original dvd to install 64 bit.

But i have heard that 64 bit its not only about more rams, but it also does like some better cache to rams of apps that u run, so it gives better performance?
take a look here, starting from 1:00 YouTube - 32 Bit vs 64 Bit

Am on a slow connection, cant open that video. But heres an excellent thread on the subject:

Oh, ty, then i might will just downgrade to home premium 32 bit anyway, i kinda feel like ultimate uses more ram or something... and i dont need any of ultimate features.
