RX4640-New boot disk (SAN)

[Miguel Santos]

I have one RX4640 install with W2003 on SAN disk.
I put those disks on a another RX4640 but it does´t work, because de disk have a different signature.
I think I have to change some thing on de EFI. How?

Try to boot manually from EFI shell. Once u r at shell use map command so u will come to know which fs is bootable, go to that and try booting manuaaly from there. One more thing check acpiconfig as it should be set to windows else system won't boot in windows. If it is default then change it to windows using the following command:

shell> acpiconfig windows

Hi Miguel,

You have to restore the Boot entry by using the NVRboot utility from Microsoft.
It's placed on the EFI partition in the MSUtil directory.
You have to import your boot0000 file. It's probably in \efi\microsoft\winnt50\boot0000.

So the steps are:
1: change to EFI partition (e.g. fs0:)
2: locate your bootXXXX file (probably boot0000, default location is /efi/microsoft/winnt50
3: cd /MSutil
4: run NVrboot.efi
5: choose I(mport) to import /efi/microsoft/winnt50/boot0000 (or wherever the file is located)
6: Quit
7: type exit to leave the EFI shell en enter the boot menu
8: choose the Windows boot entry
9: enjoy
