kristobal's right, but since I use Win98 I can explain it better: If, when booting, you don't have the startup menu appearing you'll need to either enable it or hold down the Ctrl key at the right time (too soon and BIOS will b***h about a stuck key, too late and you'll miss it). To enable it, open a DOS prompt, switch to C:\ and run the following commands: attrib -r msdos.sys notepad msdos.sys It uses a standard ini format. Under [Options], find and edit the line: BootMenu=1 If it's not there, add it. You can also add: BootDelay=2 BootMenuDelay=2 to shorten the wait so it's not annoying if you leave it enabled. Seems that one line works some places and the other in other places, but having both won't hurt. Save. Close. You can also use TweakUI to enable this much more easily. Reboot. Whichever way you do it, choose "Command Prompt Only". When it gets to the prompt, type: win /d:m Optionally, before you start Windows, you can launch SmartDrv which will help with disk-intensive tasks.
