Try this:
Copy boot.ini, ntldr and ntdetect.com (i.e. the boot files)
from C: to E: .
Then touch up boot.ini with Notepad by removing its 2nd
entry line under "[operating systems]" and reducing the
timeout setting to 0. This reduces the boot.ini to a
mono-boot scenario with the OS coming from E: .
Then, if E: is not the only RAID partition, set E: to "Active"
with Disk Management. Then, disconnet C: and try
booting.
If that doesn't work, you may need a Master Boot Record
for the RAID drives. Running the WinXP installation CD's
Repair Console and its utility "fixmbr" on the RAID setup
*might* supply that. Otherwise, I step aside for more
expert suggestions for booting a RAID system.
