using a third party product like Partition Magic.
I was doing assignment 3 in "Speed up your PC" and changed my C Drive to NTFS.
I have a dual boot setup. C Drive uses WindowsME. D Drive uses WindowsXp Home. D Drive is NTFS. C Drive was Fat32. I changed it to NTFS. Now I can't boot using WindowsME. Can I change it back to Fat32?
