Help! For some reason, my windows help and support utility is not functioning well. When I open it, it shows: Mark a partition as active __elbasuer__ __elbasuer__ Marking a partition as active is an advanced task that should only be performed by advanced users. Marking a partition as active on a basic disk means that the computer will use the loader (an operating system tool) on that partition to start the operating system. Warning Don't mark a partition as active if it doesn't contain the loader for an operating system. Doing so will cause your computer to stop working. Click to open Computer Management. __elbasuer__ * __elbasuer__ On the left, under Storage, click Disk Management. Right-click the primary partition that you want to make active, click Mark Partition as Active, and then click Yes. Notes You can't make a logical drive or an extended partition active. Only a primary partition can be made active. There can be only one active partition per physical hard disk. If you have multiple hard disks installed on your computer, it's possible for each hard disk to have a partition set as active. However, the active partition on the first hard disk that your computer's BIOS detects is the one that will start the computer. Also, all of the topics are lost! What's the possible way to reverse it? I remember in Vista, there's something about merging a key that'll fix the problem. Thank you very much in advance!
