@ huuub:
Welcome at nForcersHQ Forum!
The guide (= start post) within this thread will not be suitable for you, because it was written for the installation of Vista and not Windows 7. So if you want to get Win7 installed onto your nForce RAID array, you should better look
here.
Maybe I am wrong, but I don't believe, that you will be able to get Windows 7 installed onto your nForce2 RAID array, because the Win7 in-box nForce SataRAID drivers do not support your chipset and the Win7 Setup will not accept any suitable other nForce SataRAID drivers.
Neverthelesess you may try the following:
1. Download Squall's nForce 9.35 Remix package you can get
here and unzip it by using a tool like WinRAR or 7-Zip.
2. Copy the content of the LEGACY folder onto a floppy disk or USB stick.
3. Boot off the Windows 7 DVD.
4. When you come to the point were Win7 should detect your hdd's resp. RAID array, hit the "Advanced options" and then the "Load driver" button.
5. Let Win7 Setup load the content of the prepared floppy drive/USB stick. Give the permission to load both "required" devices.
6. If you are lucky, Win7 will now detect your RAID array as 1 single hdd device. In this case you will be able to get Win7 installed onto your nForce2 RAID array.
Please report here, if you succeeded or not.
Please remember, that meanwhile all nForce chipsets lower than NF5 have been outdated by NVIDIA. The last OS, which is fully supporting LEGACY mode nForce chipsets like yours is Windows XP.
So you should either change your mainboard or stick with Windows XP, if you don't want to break your nForce RAID array.
I do not recommend to create a JMicron RAID array, because you will be disappointed about the performance and furthermore you cannot be sure, that you will get Win7 installed that way.
