I am using win7 home basic preinstalled OS, now I am going to change the OS to Win7 premium, when the time of installing new OS stage 2 Intel Raid has block my OS currently Raid is enable how to disable that and any other option to change OS, please help me on this
When you are ready and after you have backed up all your data, then you can turn off raid in the bios and change it to apci. Depending on the type of raid you were using you may not be able to boot back up into the old system which is why I had you wait until you are completely ready to upgrade. Throw in the new win7 disk and begin the install. Be sure to format at least the boot drive.
