Explanation: The boot record provided by Windows and DOS was designed not to work past 2 GB on a FAT16 partition. VCOM provides a utility with its products to make Windows and DOS boot properly anywhere within the first 8 GB. With System Commander 2000 and Partition Commander 6, this is handled automatically. A manual method is available for other older VCOM products (but is not available on SC v3 or older):
1 From the System Commander OS selection menu at boot time, select the choice that gives the error and let it fail.
2 When the error message is displayed telling you that there is a "NON SYSTEM DISK OR DISK ERROR", insert a Windows 95/98 or DOS bootable floppy, depending on what operating system you have installed, and press the Enter key.
3 Once you are booted to the A:\ prompt, remove the boot disk, and insert the System Commander utility disk 1.
4 Type COPY scin.exe C: <enter>. When that file has been copied, type COPY SCBOOT.DAT C: <enter>. When that file has been copied, type COPY schelp.hlp C: <enter>.
5 When all three of the above files have been copied, eject the System Commander floppy and reinsert the boot disk.
6 Type C: <enter>, then type SCIN <enter>.
7 From the SCIN menu, use the arrow keys and highlight the Special Options choice <enter>.
8 Use the arrow keys to highlight Transfer System (Advanced SYS) <enter>, and then use the arrow keys to highlight Automatic Transfer <enter>. Once the process is complete, press the Esc key until you are back at a C:\ prompt.
9 Eject the floppy and reboot the computer. Select the operating system from the main Selection Menu that was giving the error, and it should boot normally.
