Upgrade dos 4.00.1111

Hi All,

I had a windiws 95 hard drive fail last week due to bad sectors.  I was able to recover the data, but the new disk won't boot.  I've got a start up floppy disk which let's me get me to a command prompt.  When I try to run window it says incorrect version of dos.  I guess it's using the version on the floppy disk.

Any idea how I can update it?

Thanks

You can get DOS 6.3 on eBay. Remember that Windows 95 and 98 had DOS roots which was (I believe) DOS 7.

OK, I found some good material here.

Windows 95 / 98 is DOS 7 internally.

I am not sure if you format a disk (FORMAT C: /S /V) with DOS 6.3 whether it will work. I have not tried that. I installed Windows 95 from the CD supplied with Windows 95.

I'm more looking for the process of upgrading.

I can't boot windows because it's an old version.

I tried sys c:

But it  said "Incorrect version of dos"
There is no way you can boot Windows 95 with DOS 4. That is not going to work.

I think you need to back up your system and start again so Windows 95 and its version of DOS will align.
I think dos 4 is the version on the startup disk.  It was made during an install using the windows 95 floppy disks.
If this is the case for very original Windows 95, Windows 95 will format as system and then use DOS 7.

Thanks.  DOS was part of the boot disk.  I found the right boot disk (Windows 95a) and the OS loaded.  Many thanks.
Glad we could help.
