After starting your previous operating system (by pressing F4 when yousee the "Starting Windows 95" message, or by choosing Previous OperatingSystem from the Startup menu), when you exit the previous operating systemsession, your computer stops responding (hangs) when you restart thecomputer.
This problem occurs with Windows 95 OEM Service Release 2 (OSR2). Windows95 OSR2 is designed to be preinstalled on new computers only, and cannotboot back into Windows 95 from a previous operating system.
To enable the computer to boot Windows 95 OSR2 again, the boot drive mustbe made bootable with the Windows 95 OSR2 Emergency Boot Diskette. To dothis, follow these steps:
Insert the Emergency Boot Diskette in drive A and restart the computer.
At the command prompt, type the following line:
Remove the boot disk and restart the computer.
Because OSR2 is preinstalled on new hard disks, there is no option tostart the previous operating system on the Startup menu. However, if youformat the hard disk, install MS-DOS and then Windows 95 OSR2, and thenboot the previous operating system, you experience the problem describedin this article. Booting a previous operating system is unsupported inOSR2.
If you need to reformat the hard disk for any reason, use the EmergencyBoot Diskette.
