Yesterday I attempted to install several new Dell D210’s with Windows 2008 x64.
Booting to the installer prompted to load some drivers for the PERC S100 controller. No problem, downloaded them from the site and inserted the driver.
After selecting the partition needed to install the OS a error popped-up: “Windows could not determine if this computer contains a valid system volume”.
After long searching turns out the problem is with the USB stick being inserted at the time of selecting the partition. No idea why this would need to be a problem but removing it after you selected the drivers, wating a minute and then moving on to selecting the partition works as a fix…
