Hello & Thanks ,

My windows 10 , x64 , died .

How to create a FreeDos Boot-Usb ? 

I have been told (they say) that plain dos cannot boot from a usb .

So I am looking at FreeDos .

I have downloaded and installed Rufus on usb ,

but it looks like I need these programs:

aufdos.exe
E172IMS.10R
flash.bat
flash_me.bat
 I can't find them anywhere .
Does FreeDos get installed on top of all that ?
If so, I need to know 'How to install FreeDos' on USB. 
 
I am leaning toward FreeDos because I am a bit familiar
with ms-dos from the old days , but Linux is a whole different animal to me .
 
 Thanks for your help !

hi vmars316

im pretty sure you can boot DOS from usb with grub4dos. i needed to do this last year and reboot pros showed me the way but i dont know which thread to search and find the info.

Wonko the Sane will probably hook you up soon with it.

basically IIRC, you make an image of a DOS floppy and use grub4dos to boot into it from a usb


welcome to reboot.pro

edit: that may not work on UEFI system though.

browse Steve675's site http://www.rmprepusb.com/he probably has the info you need there somewhere

edit2:

see here:http://www.rmprepusb...torials/freedos

Here I am :), but I wonder if we are not - by accident - falling into an x y z problem :ph34r:

https://web.archive....red-banana.html

 

There is of course usually no problem in booting DOS (or FreeDOS) from a USB stick, but what will it be its use of it in the context of "My windows 10 , x64 , died .".

 

If - by chance - it is a "pure UEFI" machine (wirhout BIOS CSM support) then it will actually be impossible as DOS/FreeDOS need the BIOS services, but even if there is BIOS support, in 99.9999% of cases the DOS won't be able to access the NTFS filesystem of the internal disk and without some specific tools it will have also no or nearly no access to the physicaldrive, in this respect the "plainer" grub4dos is more powerful than DOS.

 

@vmars316

Can you describe the machine at hand and what is your plan once booted to FreeDOS?

Thanks ,

My machine is a Lenovo ThinkPad x1-carbon , 4gb Ram, 256 ssd . 

Yes,  it sounds like grub4dos is the way to go .

 

My system goes haywire after logon.
It keeps flashing SnipTool.exe and and a bunch of other system type programs. It show all running programs as thumb nails and keeps flipping focus from one to another. 
It wipes out whatever I try to type .

 

I tried Re-installing win 10 ,

and took the less time option .

But after 3hrs , I tried to Start win10 .

So now I can only get into the Bios settings.

But after I point Bios to 1st look for a Usb .

Unfortunately, my PF-keys don't work ,

so I can't Save settings .

 

Am I truly dead in the water ?

Thanks

I am not sure to understand.

The OS had issues and you attempted to to re-install it (how exactly?) and after this attempt it doesn't even boot to the OS?

Do I get this right?

Which media do you have available (for the reinstall)?

What do you mean "PF-keys"?

 

If you already tried to reinstall and the attempt failed, then maybe there is some kind of underlying hardware issue or as well it is possible that the *whatever* media that you used for the reinstall is not the correct one (or misses some specific Lenovo driver/whatever) or the medis (again for *whatever* reason) is defective. :dubbio:

 

If the Function Keys on the laptop keyboard dont' work (even if you press the Fn key modifier) maybe using an external keyboard they will work. :unsure:
