Invalid System Disk

[ljwmis]

A user operating Win95 reported a problem with the error message "Invalid system disk. Replace the disk, and then press any key".

The error message was caught in a loop. The disk was removed - error message, the disk was left in - error message. Cold boot PC - error message. Users disk was checked - no sign of a boot sector virus.

Inserted Win95 StartUp disk and re-installed Windows System Files as per instructions found at Microsoft.com

Restarted PC with startup disk and entered;

c:
cd\windows\command
attrib c:\msdos.sys -s -h -r
copy c:msdoss.sys c:\msdos.xxx
a:
sys c:
attrib c:\msdos.sys -s -h -r
del c:\msdos.sys
copy c:\msdos.xxx c:\msdos.sys
attrib c:\msdos.sys +s +h +r


Invalid system disk error message has disappeared. Now PC confirms "Starting Windows 95", and the Windows 95 start up screen (cloud screen) appears. After a couple of seconds an MSDOS C: prompt appears and the process stops.

Any ideas about what to do next?

same message format then reinstall after copying contents of hard drive to another if possible
