As jephree stated;

Are you running 98FE or 98SE? (Right click on My Computer and choose Properties.) On the General screen, under System, it will list Second Edition if you have it.

Also the date/time stamp on the majority of system files will be;

98FE = 11/24/1998 8:02 AM

98SE = 4/23/1999 10:22 PM

(c:\command.com and c:\io.sys being two of these files.... At the C:\> prompt type in dir/a/o/p and check the date and time stamps on these two files. This can be performed from a MSDOS Prompt window.)

First thing to try is scandisk. Do this from MSDOS 7.10a.

When running Scandisk or Defrag, it's best to turn off all ancillary background processes. ie; Screen savers, Anti-virus, Spyware detectors, Firewalls, etc.

With Windows 9x you have the luxury of running scandisk in DOS. It's much faster. This is an asset if you have large partitions on your hard disk.

Boot your machine into the DOS Command Prompt Only mode. This is easiest by running MSCONFIG and choosing the Boot Menu for your startup:

Click on Start, Run, type in msconfig in the Run box. When the small window opens, click on Advanced near the lower right hand side of the window. Place a check mark in the box for "Enable Startup Menu". You will be prompted to restart. If you're ready, do so. (This Startup Menu can be removed by reversing these steps.)

Alternatively, when the machine is booting, just after the P.O.S.T. (Power On Self Test) screens finish and you see "Starting Windows 98", start tapping the Ctrl key. (You have to be quick.) This should bring up the MS boot menu. Choose Command Prompt Only.

When the boot completes, at the C:\> prompt, type in* scandisk /all/autofix/nosave/nosummary and hit the Enter key. All of your drives (partitions) will be scanned and fixed if problems exist. When the process is finished, reboot the machine to the MS boot menu again and choose Safe Mode. This will load windows with minimal drivers etc. Defrag in safe mode.

Caveat: The drawback to booting into Safe Mode is that your desktop icons are automatically arranged, and if you had your own arrangement, you will have to recreate that arrangement in normal mode. Windows doesn't provide a save feature for your icons. There are (free) third party programs available which will save your desktop arrangement.

Once scandisk finishes, try to start your system normally.

If it still doesn't start, or, starts with severe errors, boot with a Win98SE Boot Disk**, and at the A:\> prompt, type in c:\windows\scanreg/restore. Pick a date which precludes the problem.


*To save you some typing and possible DOS syntax errors (DOS is VERY PARTICULAR about the command line entries, I'll paste in a dos 7.x ( 95/98 ) batch file I made long ago to automate this process. Open Notepad and copy/paste the following lines into the empty document. Save it as scandrvs.bat in the root directory of C:. (ie; c:\scandrvs.bat)

===== Copy lines below ==========================
@echo off
%WinBootDir%\command\scandisk /all/autofix/nosave/nosummary

echo.
echo.
echo Scandisk has completed. You can now restart your system.
echo.
exit

===== End copy at above blank line ==============

When you get the C:\> prompt simply type in scandrvs and hit the Enter key.



**The above bootdisk image file is a self extracting file and has to be executed (run) from a running Windows machine in order to create the actual startup diskette on one of your floppy disks. (This image file produces the same bootdisk which 98SE creates.) This downloaded image file will format the floppy disk to ensure its integrity, write the files to the disk, then verify the file write, so it'll take a minute or three to create the bootdisk.

Ensure the floppy drive is set as the first boot device in the bios.

NOTE: When you boot a machine with this boot floppy, it creates a RAMDRIVE in system memory to contain DOS system tools/drivers. Thus it will move your "normal" CDROM device/drive letter "up" one level. (If your CDROM is normally E: it will be F: when booting with this bootdisk.)

The path to the found CDROM will be set with the bootfiles, so entering A:\>f:\setup is the same as entering A:\>setup at the A:\> prompt. There is no need to include the cdrom drive letter. The CDROM device letter will be assigned near the end of the floppy boot process, right after MSCDEX is loaded.
