Have recently purchased 3 x Acer Aspire M1640 Machines with Vista Home Premium on them. Need to upgrade them all to Vista Business however can't get them to go.
Home Premium loads OK from default and everything works ok. Bang in the Vista Business Upgrade DVD and it then can't find the SATA Drives. Have installed a second IDE HDD on the IDE Interface and it can see that OK. Have downloaded all the drivers from Acer's Web-Site for the Vista SP1 and loaded all of them on to the IDE HDD. Have then done 'Load Driver' on the Vista Install screen and pointed to the drivers on the IDE HDD, it finds the drivers OK however when going back to 'Choose Where to Install Vista" and refreshing the drives list it still only shows up the IDE HDD and says "There is not enough room on the C:\ drive (140gb free! showing from Vista Home Premium).
I've found lost of solutions for down-grading the machine to XP using Nlite however nothing much for Upgrading to a different version of Vista. What about vLite, do you think that would be a solution. Surely if runnning Vista Business setup from within Vista Home Premium and pointing to the drivers on the IDE HDD isn't recognising the drives then surely putting them onto the Vista Install disk isn't going to do the trick either or will it ?
Under the BIOS screen there's no option to change the SATA Mode :(
Any ideas anyone, pulling hair out here!
