It's some Acer that came with Vista and on the surface it looks ready for Windows 7 64 bit but no way, no how. There's an unresolved bios issue and it will never run Windows 7 32 or 64 bit.
Just a tip. To save time and posts, always add the make and model.
I try to upgrade my laptop OS from Windows Vista (32 bit) to Windows 7 (64 bit). The hardware is 64 bit capable. After booted from GD/DVD, I get the following error messages:
Windows has encountered a problem communicating with a device connected to your computer.
This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removable storage is properly connected and then restart your computer.
Info: An unexpected I/O error has occurred.
I have checked the DVD drive and it works properly on reading and writing data.
Anything I can do to resolve this problem?
