It is an Acer model M5640/M3640, Intel core 2 Quad CPU, 2.40GHz, 2GB RAM, 32bit operating system. It runs vista home, service pack 2. Explorer & my computer etc see c & d fixed hard drives but device manager dosen't. When I try to install windows 7 the install manager can't see the hard drives & when I checked device manager it wasn't showing either.

Do you have any other fixed drives in that system?

No. The C drive is partitioned into c: which has operation system & programs & d: which is the data drive.

So, did you install Windows 7 on that computer? If so, how did you go about it?

You need to start your own thread here at CN. I have removed your post as it just confuses the issues shandy is having.

So you have one physical hard drive that has two partitions? Are you trying to boot to the Windows 7 DVD?

I have the same problem.

I have an XP SP3 PC desktop System and I am trying to upgrade it to Windows 7 and during the Windows 7 install -- the install process can not recognize / see the C drive.

Any thoughts?

shandy - substitute the Windows 7 DVD in the following with the Vista DVD
velar001

If the bios DOES detect the SATA drive(s), but the Windows 7 DVD does not......

If the mboard's bios Setup has the SATA controller(s) in SATA a.k.a. AHCI mode, then the files initially loaded from the Windows 7 DVD cannot recognize SATA drives because there are no SATA controller drivers for your mboard built into the DVD.

The easiest way to get around that is....
If you change that setting in the mboard's bios so the SATA controllers are in an IDE compatible mode of some sort, then the files initially loaded from the Windows 7 DVD WILL recognize SATA drives, as IDE compatible drives.

Doing that will allow you to run Setup, then when Setup has finished and you have loaded the drivers for your mboard and it's devices, including the SATA controller drivers, then you can go into the bios and change that setting so the SATA controllers are in a SATA or AHCI mode.

Whatever that setting is, it's presently set to SATA or AHCI, it's changeable, and at least one other choice is an IDE compatible choice, Save bios settings.
