Windows 7: Can Install 32 bit; cannot install 64 bit version

Can Install 32 bit; cannot install 64 bit version

Hi, I have just built a computer and I am trying to install Windows 7 64 RC 7100. I already instaled Windows 7 on another PC (on a partition to be precise) and it works fine. I used the same DVD (so it should be a good one) but when I try to boot from it on the new computer, it says it is copying windows files, then goes to the "Starting Windows" screen and stays there. Everything stops, no HD or DVD activity, and the USB LED turns off

I replaced all components on this build with the ones I have on my older computer where Windows 7 works, no success. I put the new HD in the old build and installed Windows 7 on it succesfully. When I plugged it on the new M4A78 plus, it hangs as well (I intended to do a repair installation, I cleaned most of the drives before I swapped computers)

I installed XP32 and Windows 7 32 on this build and they work fine, so I don't think there is a HW problem, but some incompatibility. I bdownloaded iso from MS directly and burned 3 copies at low speed, no difference
I wrote to Asus but they said they cannot supportr Windows 7 yet. Called them and they told me to call Microsoft. ... Yeah... right....

Any suggestions?

My configuration:
RC 7100 downloaded from MS and burnt at slowest speed
MoBo Asus M4a78 Plus
AMD 4200+ (taken from the old computer, worked fine)
4G DDR2 800Mhz Patriot (tested for 5 hours with Memtest, OK. I tried with 2G only and with 1G stick as well)
ATI Radeon HD4550 (works on the old computer. I also tried with GeForce 9500, no difference)
HD Western Digital 320G SATA (new, installed Windows 7 64 on it in the other machine)

Thanks

Maybe bios setting like max mem, legacy floppy support, or # of cpus. All should be unchecked

Hope this helps

Also check for ACPI XSDT Table settings in your BIOS while you are at it They are only used in 64 bit installs so it is likely disabled.

If all else fails... Give it time. I have installed Windows 7 on 5 machines so far, and only the one I'm currently on has ever had problems with it. The install on this machine took several hours, with each "Starting Windows" screen with the colored window taking upwards of 30mins+ to progress, all the while the system seemed idle although it did eventually finish. To test this just simply start it before you call it a day and leave it sit over night :P

Thank you zigzag, thank you Snives
I forgot to say I have played a lot with the BIOS as well. I have tried several options and have disabled everything not being used for installation. I also tried plugging the monitor to the VGA port. I have left it for several hours sitting there before and nothing.
Having said that, your other suggestions I had not tried yet. Unfortunately, zigzag, there are no options for max mem, legacy floppy support, or # of cpus. Snives, I enabled ACPI 2.0 (ACPI APCI was enabled) but it didn't help. It is right now stuck at the "Starting Windows" screen. I will leave it anyway, probably overnight and see what happens. Oh, I never get the colored window, it stops before that.
I suspect I need to slipstream the drivers for the video card in my installation CD. I just started reading about it, if yuo have any hint about, it is much appreciated.
Thanks anyway, and any other pointer is much welcome

Vista Home Premium 64 bit
 
 

I had a similar problem when I bought a new system and tried to install 64 bit Vista on it, my problem turned out to be a fault with the dvd drive (which was also brand new), I bought a new drive (about 20) and that solved the issue. Do you have another drive to try ?

I tried that. Both the IDE drive from my other computer as well as a SATA drive I bought anew. No success...

Have you applied any BIOS updates available?? I know with my ASUS notebook, upgrades to the BIOS were required to ensure full x64 rollout - even though everything else was x64 capable. Did that and everything ran just fine.

Thanks Kaninelupus
Yes, I am using the most recent BIOS from ASUS. I check regularly to see if they publish another one that could help, so far nothing

Did you ever find a resolution to this? I'm dealing with the same thing... hangs at "Starting Windows" during install, or at "disk.sys" if I try through safe mode.
