I don't want 64bit, and I don't want Home Prem. That is what is on the computer I purchased. It is the extremely tiny Acer 3610, I need help from those who know what that is (please, take just a second to eyeball it). It runs Atom 330 +Nvidia ION, and comes with 2GB ram. I think it is ridiculous to put a 64bit OS on this machine. So, I HAVE purchased W7 Prof. Upgrade (RETAIL), and I also have XP Pro OEM both from Fry's. I will also be playing with various Linuxes, esp Sabayon and Mint, on triple boot, later. So, I think I know: XP then W7 then Linux. I intend to prepartition the disk accordingly, with Linux Home & swap, and NTFS Documents, on logical partitions. I guess I will be eating the cost of the installed W7x64, as well as the Acer paper-only warranty (they are absentee landlords, nearly as I can tell). Could someone please give me some comments and suggestions, and an explanation of this weird 100 MEGA-Byte! partition between the first partition (recovery) and the active bootable third partition ("C:")? Help? Links to reading material is also welcomed. Anyone, please?
