Let me explain what iam doing:
1 - installed MS DOS 6.22
2 - installed all drivers, added some "must have" things config.sys and autoexec.bat
3 - EVERYTHING work perfect ... super DOS Gaming PC ... duke nukem 3D, Doom, Transport Tycoon, Monkey island ... general midi ok, MT32 emulation ok ...
now i want also windows 95
4 - installed windows 95
5 - W95 work fine
now i want switch to DOS 6.22
6 - from boot menu "F8" select Previos version MS DOS
7 - DOS 6.22 start OK
and now
8 - after ctrl+alt+del from DOS i want back to W95. PC not booting ... no DOS, no windows it just stop after post screen
why it happen?
You may be hitting a variant of the scenario described here : http://www.mdgx.com/osr2.htm#2BOOT
As for recovery, you may be able to just boot with a DOS 7.0 bootable diskette (or the recovery disk that Windows 95 offered to create during installation) and, if the CF card is accessible, run
a) fdisk /mbr
b) sys a: c:
c) try to reboot from the CF card and hope for the best .
I don't know if this might "break" the boot from previous OS (DOS 6.22) functionality .
Once you get back to a working state, I also strongly suggest you backup your CF card using something like Clonezilla or Acronis TrueImage . This can save a lot of time and frustration .
That being said, I have always believed that using the "Previous version of MS-DOS" option in Windows 9x is not a good idea .
IMHO, it is of nearly no practical value and just adds one more potential point of failure to a given setup. There is practically nothing useful that DOS 7.x (bundled with Windows 9.x) cannot do just as well as 6.22 . See Re: DOS 6.22 and Windows 98 SE Multi Install
If you absolutely want DOS 6.22 for nostalgia reasons (perfectly valid reason, IMHO), I suggest that you use a separate CF card for it . This would
a) Avoid the issue you currently have
b) Not limit you to 2GB partitions and 8GB max disk availability on the Windows 95 side of things (assuming your version of Windows support FAT32)
