Opening current filesystem using DOS in UBCD

Message

Hello, I have the DOS 6.22 IMG File in my UBCD which I put there with the custom IMG section.

It runs fine and I can use all DOS commands there except that it only executes on the A:/

I need to change a few windows system files but cannot do it since Vista uses those files during runtime. Can I copy those files to the required folder from booted UBCD tools?

I have Vista and sadly it does not come with DOS pre-installed. I just have a single System Partition, and another for recovery purposes (im using compaq). I created a 100 meg volume from the free space in the recovery drive so as to house DOS if it is required.

Can anyone give me the instructions, be it accessing the file system from Booted disc or to install DOS in the system?

The files I'm talking about is in WINDOWS/system32 and the to-be-copied files are in another folder in C:/

Thanks a lot..

Dos doesn't have ntfs support by default.

You can try the FreeDOS image of UBCD (has an ntfs driver), which is used for almost all dos programs on UBCD. Just launch a dos program and exit it.
Remember, ntfs support under dos isn't very reliable.

You better download a linux distro like Puppy Linux or Parted Magic and burn it to an iso.
Or download UBCD50b12, which has Partted Magic included.
NTFS access (read/write) is very reliable those days. I never had any problems with it.

Or if you just need to copy some files, you can use the recovery disk of Windows Vista and go to the command prompt to copy the necessary files.

Can you teach me how to use the recovery part of Vista to copy files in command prompt? I just need to copy it when Vista is not using those files, mainly they are used in explorer but some are used in others like SVCHOST which I dare not interfere with.

Some information on how to startup the recovery console (see last screenshot for the Command Prompt: jsut click on this text when you see it at boot time)

Look at: http://www.besttechie.net/forums/Vistas ... 12840.html to see some commands that you can use at the recovery console.
If you type 'help' you also can see the available commands.

For copying files, you probably need something like this (I haven't used windows in a very long time, so be warned

):

Code: Select all

copy "C:\WINDOWS\system32\somefile.exe" "C:\somefolder\"

This will copy the file "C:\WINDOWS\system32\somefile.exe" to the folder "C:\somefolder\".

You can type:

Code: Select all

help copy

it will give you the explanation on how to use the copy command.

I think that you also can use xcopy. It can do more than the copy command: e.g.: recursively copy a directory. Search on the internet or with the help function, how to use it.
