Windows ME installs [and can't even boot without] MS-DOS 8.0, a stripped-down version of the better MS-DOS 7.10, which is installed by Win98 + Win98SE.The good news is MS-DOS 8.0 can be made "better" with 1 of these real mode DOS patches: http://www.mdgx.com/dos.htm#ME If you have a USB/Firewire keyboard, you need an old style [legacy] PS/2 port keyboard that works from native MS-DOS [C:\ prompt], without Windows drivers. Every computer motherboard has a PS/2 port in the back of the computer case. Just borrow one and plug it in. Then press F8 to boot into Safe Mode: http://www.mdgx.com/msdos.htm#MEN P.S.: When you get back into your PC desktop, you may want to uninstall the old PC Cillin software, and find a better/free A-V tool. Startup, Run, RunOnce, RunOncex, Setupx, WIN.INI run/load etc... entries can be disabled/deleted from safe mode. Try to run: msconfig HTH [Hope This Helps] But I want the Boot into DOS option available in the Shutdown Dialog, Can anyone make that happen?
