I notice that (in Win200 at least) the check on the 1st 2 bytes of an exe being 'MZ' does not take place.

Anything known?

It does on my win2k machine.

I just changed MZ header and file turned into MS-DOS executable.

.EXE files on windows are PE files and therefore should adhere to the standard specified.

Venet, thanks, but what I meant was that if you change the MZ (which appears in all exes) to, say, XX, then it still runs.

There was a time when the OS complained if this signature was not present.

Sorry for misunderstanding.

Not really an OS, rather DOS

Changing Boot Disc

I've a Windows 2000 Server which currently has two phyiscal hard disks. The partitons look a little like this:-

Disk 1 (60GB)
=======
c:\ 2GB (used to be Win98) Boot Partition
d:\ 30GB (mirrored onto disk 2)
e:\ 10GB (Windows 2000 Server System Partition)
f:\ 18GB (stuff)

Disk 2 (30GB)
========
30GB mirror of d:\

What I want to do is copy d:\ to a new 60GB disk, use Disk 2 as the system boot partition, and then mirror my new 60GB disk onto the current disk 1. Is is imperitive that the Windows 2000 installation is not corrupted in any way as it runs my entire network.

Can anyone give any pointers about the best way to do this? I can get access to Partition Magic if needs be.

BIOS?

Hi,

I wanna install a new version of Windows (W2k) but I encountered a problem.
During installation after copying files from the CD-ROM to the hard disk the computer needs a restart. This is normal.
What is not normal is that after the restart the installation begins from the very beginning with copying files to the hard disk again.

I suspect (but I may be wrong) that the BIOS settings are wrong. I tried CD-ROM and hard disk as first and second boot devices but the same problem persists.

Could somebody give me please a pointer?
Thanks
