Using the recovery-repair diskette

In some circumstances, files on your hard disk might become damaged so that the
F11 prompt is not displayed when you start your computer. If you have attached a
diskette drive to the computer and created a recovery-repair diskette, use the
following procedure to access the Product Recovery program on the hard disk. For
instructions to create a recovery-repair diskette, see "Creating an emergency
recovery-repair diskette" on page 18.
Complete the following steps to use the recovery-repair diskette:
1. Insert the recovery-repair diskette into the diskette drive.
2. Turn off your computer.
3. Turn on your computer, and follow the instructions on the screen.
If the repair operation is completed without error, the F11 prompt will be displayed
the next time you restart your computer.
If an error message is displayed during the repair operation and the repair operation
cannot be completed, you might have a problem with the Product Recovery
program or the partition that contains the Product Recovery program. Use a Product
Recovery CD to access the Product Recovery program. To obtain a Product
Recovery CD, contact IBM. See Appendix A, "Getting help and technical
assistance," on page 113 for details.
