203505, DOS command SYS
Posted by _Chewy_, Mon Mar-10-03 08:06 AM
2 Part question:

If you have a dual-boot setup with Win9.x/ and 2K, and you later decide to get rid of the Win9.x, i think the way i was told a long time ago was to boot up the PC using a win9.x boot up diskette. At a DOS prompt, type in "SYS C:"

1) Is this the best method and;

2) Does the "SYS C:" command work the same in an NT environment? In other words, if you type that command using a W2K boot diskette, does it still copy the system start up files on to the boot sector specifically for W2K?

TIA.

This will probably wipe out your dual boot configuration and make it so that it boots straight into Win98.

Then my memory must be faulty cuz there are further steps to the direction i'm not remembering fully.

As for the 2nd question, can anyone verify that?

Yes, I can verify that. The answer is no, there is no sys command in Windows NT based operating systems. To fix the boot loader, you have to repair Windows NT (or for Windows 2000 and Windows XP boot with the CD and start the recovery console and use the fixboot command, though this will not restore missing boot files like sys c: would on a win9x system)

Also, in Ttech's answer, change the word "probably" to certainly will wipe out your boot loader if you do sys c: to a dual boot system. It's the exact opposite of what you want to do.

If you want to get rid of Win9x from a dual boot with Windows 2000, about all you can do is edit boot.ini to remove the C:\="Microsoft Windows" line so it doesn't show up in the boot menu anymore, and delete c:\windows and any program directories you're not going to be using anymore. You can then use the space on the C: drive to install applications or whatever you want.
