Hey guys, you two seem to know what the heck is going on. I made a boot disk using my laptop, which is running windows 98. From that I can get my desktop, which uses windows 95 to boot to the a drive. I know enough to type c: and get to the c prompt. What do I do then to run windows?? What is the command to type? i have gotten into the windows directory using the dos commands but have no idea where to go from there.

Be specific, I'm pretty clueless about this stuff. Thanks for any help. Matt

Well, I'm not ReddDogg or Dan but I think I can handle this one. http://www.PCGuide.com/ubb/smile.gif I don't really understand what you are doing there: why do you need to boot from the A: drive on your desktop?
Anyway, the command to invoke Windows is normally just "win" at the command line.

ixl - thanks for the reply. Here is what happened/is happening. I have a desktop machine that is running win95. I have a laptop (that i am writing you this reply on) that runs win98. I was using my desktop and trying to get my scanner to work ( i was getting a memory error when i tried to run the paprport software). Anyhow, in an attempt to make more room/memory, i tried to run defrag. that gave me an error message saying that i needed to run scan disk first. i attempted to do this and got an incomplete scandisk. not thinking anything of that, i attempted to reboot the machine, only to get the following message: "invalid system disk Replace the disk, and then press any key." Of course, there wasn't a disk in the A drive or anything obvious like that. After repeated attempts I have realized that this is not gonna just fix itself. After doing some "surfing" i came upon someone telling me i can make an emergency bootup disk ( i have the win95 cdrom, but not a win95 startup floppy). I thought that i could use my laptop and the win95 cdrom to make a win95 start up disk. i couldn't seem to make that happen, but was able to create a win98 start up disk. hoping a later version of windows might work, i tried it. it did seem to work, getting me to the A prompt from which i got to the C prompt. looking at the directory, it looks like everything on my harddrive, but i just can't seem to make the machine boot windows up. using the startup disk i got to the c prompt, then changed to the windows directory and typed "win" hoping to get windows to boot. At this point all I am getting after i type that is the following message:
"you started your computer with a version of ms-dos incompatible with this version of windows. insert a startup diskette matching this verion of windows and then restart. the system has been halted. press Ctrl+Alt+Del to restart your computer"

At this point I am desperate to find a bonafide Win 95 startup disk, not a win98 one. is there any way that you think i can do that using my laptop and the win95 cd? when i try to open up the D drive of my laptop with the win 95 cd in it (remember, the laptop is win98) i get a message basically saying i am already operating a better version of windows). I thought i might be able to make a new file folder in explorer and copy the entire cd to that directory and then run win95 out of that and create a startup disk that way. obviously i don't want to risk screwing up the only operating computer i have at this point! someone emailed me telling me that he thinks i need to reformat! of course that would mean wiping out all of the info on the drive!

Help me out and i'll owe you a cold one of your choice!

Thanks - Matt

First of all, do *not* reformat your hard drive. http://www.PCGuide.com/ubb/smile.gif
The best solution here really is to find someone else with a Win95 machine and make a boot disk on that PC. Make sure htey have the same flavor of Win95 as well--they aren't all the same. Unfortunately MS operating systms are a bit picky about DOS versions (and that's what we are talking about here really, the DOS that runs under Windows.)
There's no real way around this without something that will boot Win95, unfortunately. Keep us posted.

If it says invalid system disk when you try to boot from hard drive, which is the real problem here, doesn't that indicate that the fat table is corrupt or the master boot record, or something along those lines? Then again, if it does recognize the c: drive after booting to command prompt using windows 98 startup disk, then fat table should be ok. Here is what I would do in your shoes right now. I would boot using the windows 98 staratup disk. run scandisk /all to do a scandisk and a surface scan on the computer. After that, try runnign defrag. Those can all be done from 98 boot disk, least it has always worked that way for me. If that doesn't cure the problem of it not booting on it's own, then try the boot disk idea of charles. As for making windows 95 boot disk, it is same as making a windows 98 boot disk, and even if you are in different version of windows 95 than the one on the desktop computer, if it copies the files from the cd it should be a boot disk of same version as that on the cd.

Windows 9x boot disk creation

A windows 9x boot disk is simply a formatted floppy with the FAT file system. It contains special files that make it bootable. They are
COMMAND.COM
MSDOS.SYS
IO.SYS
DRVSPACE.BIN (optional)

So to create one you can simply format the disk in the 98 machine, then
find these files on the win95 cd-rom and copy them to the floppy.
The version of these files (maybe only command.com) determines the dos version.

Some other files that may be useful in a boot disk
HIMEM.SYS - extended memory support
OAKCDROM.SYS - CDROM driver
MSCDEX.EXE - CDROM Drive support for DOS

You should copy the lines from autoexec.bat and config.sys from your hard drive that reference the above 3 files and create minimal autoexec.bat and config.sys files for the boot disk. Note that your cdrom driver may not be oakcdrom.sys.

You may want to copy other useful utilities like
EDIT
FORMAT
FDISK
SYS
SCANDISK
CHKDSK

The following MS knowledgebase article may be useful in case you have to extract any of these files from a .CAB file, Q129605 (http://support.microsoft.com/support/kb/articles/Q129/6/05.asp)

You can do it that way Will, but my way and charles way is quite a bit easier, and you get to the same place. I am a true geek, driven by laziness, which in turn makes me try and think up ways to eliminate work http://www.PCGuide.com/ubb/biggrin.gif

Boot disks for DOS or Windows can be downloaded at Boot Disk (http://www.bootdisk.com)

Make sure and read their instructions, the files posted are self extracting files, not the bootdisks themselves.

Also, it sounds like you lost your system files somewhere along the line. Here's what I would do:
1. Boot to a win95 bootdisk and replace the system files. At the A:\> prompt type:
sys c: making sure to put the space after sys. After a few seconds you'll see the message System Transferred
2. Run scandisk. Again from the A:\> prompt type this command line for an unattended scandisk:
scandisk c: /autofix /nosummary /surface
This tells scandisk to automatically fix errors without the pop up prompt asking if you wish to fix errors, and to run a surface scan as well. Remember the spaces before c and each /.
3. After scandisk is finished, boot to Windows, assuming everything went well, and run Defrag.

If you had everything...Where would you put it?

Sorry... used to using NT boxes where you have to work to make a 9x boot disk.
