I bought a computer a year ago and was never able to defrag it because for some reason the C: drive would never show up. So googled my issue and found something about checkdisk utility Heres the thread: http://windows7forums.com/windows-7-support/25097-windows-7-disk-defragmenter-doesnt-list-c-drive.html Anyway, as you can see, it went as wrong as it can go... It told me I needed to schedule the check for the next restart so I did. I restarted my computer and now it just says BOOTMGR is Missing. I've read other threads about this and none of them help me at all.. I have no installation or recovery disks since windows 7 was on my computer when I bought it new... Someone PLEASE help me.
