upgrade windows 7 32 bit to 64 bit

2009-12-30, 14:55 PM

Just got my t400 with 4 gigs of ram, but forgot to order 64 bit windows, so I only have 2.46 gigs of "usable" ram.  I talked to lenovo, and they said I'd have to return my laptop (and pay a 15% restocking fee) in order to get 64 bit, which I do not want to do.

 

I can get windows 7 ultimate 64 bit for free through work.  I am wondering if it is possible to format the hard drive, then install windows 7 64 bit.  I assume I would then have to download all of the 64 bit drivers off of lenovo's support page.  Is there anything that I need (drivers/applications) that I would not be able to get off of lenovo's website (for instance, something that is on the recovery partition)?

 

Thanks.

Yes, i did the same. I had a Win7 Ultimate Upgrade CD 64 bits. The laptop had Vista Business (32 bits) on it. You can not upgrade from 32->64 so you have to choose a new installation. No need to re-format yourself. The install will do that for you if necesarry. Even better, that way Microsoft can check if you are legimate to use an upgrade CD (or not). The install went very smoothly. In 15 minutes i was running 64 bits. Then i did the Windows Activation first. Because i wanted to make sure i am a legimate user according to Microsoft (of course i know i am but does microsoft?) before going through all the trouble of installation of applications etc...Also run WIndows Update to be sure.

 

When i was activated (succeeded immediatelly) i downloaded and ran the Lenovo System Update program. That will download everything you need (and more) from the Lenovo site.You can also download the newest BIOS. I would do that as well and i think that doesn't come with the System Update.

 

After that the most intensive work starts. Installation of all your favourite applications and setiings.

 

Have a nice vacation! At least you have something on your hands now! ;-)

Oh and one more thing.  I could also delete the recovery partition, correct?  I would think that once I have a different operating system installed, the recovery partition would be useless...

I removed it yes. Because i am using Acronis for backup/restore.

 

Good luck,

System Update 4.0 is able to update the BIOS. At least it updated mine on a W700.

I'd keep the recovery, just in case you need, erm, recovery. Make sure your Win7 64 is running well enough before deleting the partition.

I kept both the Lenovo and Service partitions. The space consumed is minimal and they might come in handy one day.

I can't speak to Win 7 since my T400 has a MS Win 7 installed - not the Lenovo version - but in XP and Vista there are things in C:\SWTOOLS that aren't available for download.  The DVD player for one.

 

It would be a good idea to burn that set of folders just in case before you wipe it and move to the new OS.

Re: upgrade windows 7 32 bit to 64 bit

I just tried to upgrade my 32bit Win 7 X61s to 64 bit (enterprise, not Lenovo software) and it said that it couldn't find the driver for my Lenovo CD rom so it wouldn't install.  Where can I find that?

Thanks
