how do I change vista business 32 bit to windows 7 64 bit on a w700

2009-11-03, 21:27 PM

I bought a full install 64bit windows 7 but the w700 wont boot off the dvd -- says there is no valid boot on the disk

the 32 bit dvd boots fine, obviously there is something missing in the prom. how to I get whatever is necessary to boot off the 64bit windows software.

 

As you all should know, the w700 doesn't support 32 bit windows 7 so I would hope lenovo will us poor suckers a break and tell us how to convert to the 64bit version

As a first step, have you updated your BIOS to the latest version?

Microsoft does not provide any clean upgrade path from a 32-bit operating system to a 64-bit version.  Basically, you will have to do a clean install.  You can simplify the migration process by using System Migration Assistant at http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50889.

 

With regards to the boot problem, I have found that certain discs and/or certain optical drives will take longer to initialize which can cause them to be skipped during the boot sequence.  To work around this, press F12 during the ThinkPad splash screen until you see "Prepaing Boot Device List"   When the boot menu comes up, select the optical drive and hit enter.  Sometimes you may need to wait a few seconds before hitting enter in order to allow the optical drive to fully initialize.  After hitting enter, the disc's boot loader will start and you'll see "press any key to boot to CD / DVD..."

 

If that doesn't work, try booting the media on another computer; it's possible the disc is defective (or has some dust on it.

Confirmed that the latest W700 BIOS (2.08-1.05) does resolve the issue.  Updated BIOS and the W700 will now boot to the install disc without having to use the F12 menu.

 

BIOS is at:  http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70800
