I just bought a brand new Lenovo 3000 Y410 laptop. It came with Vista Premium installed. I am not ready to start using vista because I use a lot of very expensive older software that is not compatible with vista. Normally I would just wipe the hard drive and install XP, but this laptop has some weird configuration issues that I know that I will not be able to duplicate if I ever decided to upgrade to Vista (when Microsoft stops supporting XP). This is why I want to create a dual boot system and leave the OEM customized partitions in place. Here is a list of the 3 partitions listed under Disk Management (NOTE: The first drive listed does not have a letter or a name and does not say what the file system is.) Drive 1 -(No Name) Simple Basic (No File System) Healthy (EISA Configuration) 13.81 GB, 100% free Drive 2 -C: Simple Basic, NTFS, Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition), 29.39 GB, 41% Free Drive 3 -Lenovo D: Simple Basic, NTFS, Healthy (Logical Drive). 106 GB, 100% Free Here is what I have already tried. I have tried to install XP with Vista Loaded. Vista says that it cannot install the OS because it is older then the current. I have tried to install XP by booting off the XP disk. When I reach the drive selection screen it just shows a single partition C: of 131 GB. I assume that installing XP on the primary partition will wipe out my Vista installation which is not what I want to do. I used Vista's Disk Management utility to Shrink the D: partition and create a new 20GB NTFS partition called, XP. I then booted from the XP disk and it still shows only a single 131GB partition C: I reversed the previous step and booted off of my Vista Installation disk. When I reached the drive selection page, I pressed SHIFT+F10 to open the command prompt utility. Using the DISKPART command, I shrank partition D: by 50% and create 53GB of unpartitioned space. I then booted from the XP disk. XP setup still shows a single partition Cf 131GB. Just to make it clear, Vista can see the partitions I created, but the XP setup cannot. Any Ideas or help of any kind would be greatly appreciated.
