SYMPTOMS
When you are installing Windows 95, you may receive one of the following error messages the first time Setup restarts your computer:
- Missing Operating System
- Invalid System Disk
When you receive one of these error messages, the computer no longer
boots from the hard disk.
CAUSE
There is an incorrect value in the Partition Boot Record (PBR) on the
hard disk. Any computer with a mis-match in the number of read/write heads
reported by the Partition Boot Record and the system BIOS will likely have
this problem.
If there is a mismatch in the reported number of read/write heads, the
C:\Setuplog.txt file contains unequal numbers on the following line:
FSLog: BIOS Heads=:64:, BootPart Heads=:64:
RESOLUTION
To correct this problem, follow these steps:
- Restart your computer using the Emergency Startup Disk.
- Use the SYS command to transfer system files to the hard disk. For
example, if the Emergency Startup Disk is in drive A, type sys c:.
- Remove the Emergency Startup Disk from the floppy disk drive and then
restart your computer. Setup should continue.
If you do not have an Emergency Startup Disk and cannot obtain one, start
your computer using a Startup disk from your previous operating system
(such as MS-DOS). Use the SYS command to transfer the system files to the
hard disk, restart the computer, and then run Windows 95 Setup again.
