Windows 7: Installation trouble 32-bit to 64-bit

Vista Business
Installation trouble 32-bit to 64-bit

Hi everybody,

I run Vista Business (32 bit) on a Dell Vostro 1520 and I want to go to Windows 7 Professional x64 (I have 4 GB RAM and with 32 bits it would only see 3 GB). I checked if my system was able to run it and it does.

I want to go from 32 to 64 bits so upgrade is not an option. So I burned the ISO to a DVD (because when I mounted the image and tried to install it like that and it said that the program wasn't compatible with 32 bit...). I used Windows Easy Transfer for my files and stuff...

(I got my version of Windows 7 from MSDN Academic Alliance for students)

Everything looks normal:
- I boot from DVD
- I can select language
- I click "Install.."

and then it says:
"Header: Load Driver
Text: No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK"

I don't know what this means but I tried the installation CD "for reinstalling Dell Vostro 1520" -- I gues the initial drivers are on there...

The only drivers that showed on that CD was something like "Intell...SATA..."
I selected this one and clicked next... nothing happened... I got an error again about drivers that can't be find.

There was an option (check box) with "Hide drivers that are not compatible with hardware". When I unchecked the box it showed a lot of 'Intel' drivers but I didn't try with these.

What should I do?

Thnx in advance!

This is most commonly a bad burn. Use ImgBurn at 4x speed with Verify. Make sure the ISO says "Bootable" in text at left when loaded.

Next make sure you have the latest BIOS version update, installed from Windows preferably.

If no later BIOS version, clear your CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Check also in BIOS setup what your SATA controller setting is: Try AHCI first, then IDE if necc.

Wipe the HD to get a cleaner slate:

In rare cases you may need to insert your SATA controller at "Load Drivers" prompt during install. Unzip to stick or CD to load.

Windows 7 Ultimate x64 SP1

I just posted a reply to a similar issue. Get a USB flash drive and install Windows 7 x64 from it instead of trying to install from the optical drive.
