    c. Yes POST -> Hard Drive -> RESTORE
    d. Yes POST -> Hard Drive -> FDISK
    e. Yes POST -> Hard Drive -> RESTORE
3. Boots, but hangs after OS begins to load
    a. Restart to Menu -> Last Good Configuration
    b. Restart to Menu -> Safe mode

    b. Un-encrypt
        i. Cipher /D
7. Memory Issues
    a. Enough RAM?
        i. Failed
            1. www.memtest86.com
        ii. Computer requires more for current usage?
            1. Task Manager/Virtual Memory
    b. Memory Management for Older Computers

            1. May require preboot execution
        iv. Defragmentation
            1. Linux filesystems self defragment; you do need free space (about 20%) as
                ext2/3 avoids fragmentation if there is enough space to write contiguous files.
    b. Troubleshooting
