ERD is gone and ASR is replacement for it.
I strongly recommend you take backup of your system, specially if you
installed extra software.
To do ASR you will need:
a) backup media
b) WinXP bootable CD
c) one diskette
Your backup media can be tape, physical disk, another partition. I didn't
test burning directly to a CD/DVD, but it might be possible too.
ASR will backup your entire C: drive. It will also write two configuration
files to diskette.
If you need to restore from ASR, you boot from WinXP boot CD. During boot
process you press F2 (I think) to enter ASR mode. You then supply backup
media and diskette. The process then continues by installing WinXP and
restoring contents of C: drive.
