hello,

I am trying to install win-7 64bit on my Latitude E5510(original OS is win-7 32bit, 4GB RAM,  BIOS Revision A07 )

Win-7 64bit installation disk, I prepared, is professional version 6.1(build7601 SP-1 DSP).

Installation of win-7 64bit was successes completely.
But, I failed to 64bit drivers installation 2times.
That is;

1st trial: Latest driver installation

All drivers were downloaded from dell site selected by TAG No. and win7-64bit.
Driver Installation order is as follow:
This installation order is as indicated DELL Japan's document " 233492_ja".

1. DELL_SYSTEM-SOFTWARE_A01_R260746.exe
2. INTEL_CHIPSET-SOFTWARE-INSTA_A05_R302424.exe
3. RICOH_R5U24X_A04_R263985.exe
4. Intel_AMT-HECI_A01_R276873.exe
5. IDT_92HDXXX-HD-AUDIO_A17_R278544.exe
   (This is audio driver)
6. VistaWin7-64_15.22.58_2993_Dell_setup_ZPE.exe
   (This is video driver)
7. BROADCOM_57XX-GIGABIT-CONTRO_A07_R296615.exe
 
At System restarting after installation step 7, win-7 could not start and was shift to recovery installation mode, but system could not be recovered.

2nd trial: driver installation from RESOURCE disk

All drivers installed are packed in Resource Media P/N 4W4YG Rev.A01.

After system image recovery of 1st trial win-7 64bit clean install image, I installed drivers.
Driver Installation order was as follow:

1. DELL SYSTEM SOFTWARE : R260746 Rev.A01
2. INTEL CHIPSET SOFTWARE INSTALLATION UTILYTY: R257446 Rev.A02
3. RICOH R5U24X Rev.A04 :R263985 Rev.A04
4. Intel AMT-HECI Rev.A00 :R262412 REv.A00
5. IDT 92HDXXX-HD-AUDIO Rev.A14 :R260701 Rev.A14
   (This is audio driver)
6. Intel QM57/QS57 NB Gfx-Intel GMA HD Rev.A01: R260904 Rev.A01

8. Intel Intel(R) WiFi Link 6200 Rev.A00: R257239 Rev.A00
9. Dell Multi-touch touchpad RevA03: R262226 A03
After step 9, restarting system, I found in Device Manager screen, touchpad was marked with "!" and "code10".
To solve this problem, I installed latest driver "Dell Multi-touch touchpad A09", then tried to re-start system.
However, System could not start, and was shift to recovery installation mode.

Above 2 trials were failure, and I can't solve this problem.

Anyone, please teach me how to install win-7 64bit and drivers correctly.
