Reinstalling the operating system involves loading the image from the Reinstallation media onto
the boot disk and, after Windows Server 2003 is loaded, specifying the server settings.
CAUTION: Reinstallation overwrites all files on the boot disk. The boot disk is determined by
bus search order and might not be the disk you expect it to be. HP recommends disconnecting
or unplugging all drives from the server except the boot disk. This includes all SAN storage, too.
Load the system image
To reinstall Windows Server 2003 from a headless console, complete the following steps:
1. From the headless console, log in to the MP using a terminal emulator such as HyperTerminal
or PuTTY.
2. Boot the server to EFI.
3. Because Windows Server 2003 cannot create a boot entry if one already exists, you must
delete the existing boot entry. To delete the boot entry:
a. Do one of the following:
• If you are using the Enhanced EFI Boot Manager Menu (grey background), select
EFI Boot Manager Menu > Boot Configuration > Remove Boot Entry.
• If you are using the Legacy EFI Boot Manager Menu (black background), select
EFI Boot Manager Menu > Boot Option Maintenance Menu > Delete Boot
Option(s).
b. Arrow down to select the Windows Server 2003 boot entry to delete and press Enter.
NOTE: The next step applies to factory-installed systems that require the use of the HP
Reinstallation media only. If the Windows boot entries are not all deleted, the boot file
bootxxx.efi is not created.
4. Insert the HP Reinstallation media in the DVD drive of the target system.
IMPORTANT: If you are installing an HP Virtual Machines (HPVM) Windows guest, you
also need to issue an IN command (for “insert”) from the HPVM console menu every time
you insert a disc. If you forget to do this, the server does not recognize the disc and appears
to hang.
NOTE: With rx2660, rx3600, rx6600, BL860c, and BL870c servers, you can also use Virtual
Media (vMedia) as the source of the reinstallation image.
5. Reboot the server.
6. At the MP> prompt, on the headless console, enter the CO command to launch the live console.
NOTE: With rx2660, rx3600, rx6600, BL860c, and BL870c servers, you can also use Remote
Serial Console to perform this step.
7. Select EFI Boot Manager menu > Internal Bootable DVD and press Enter. The server boots
from the HP Reinstallation media.
8. At the SAC> prompt, enter the cmd command.
9. Switch to a new command channel by pressing Esc+Tab.
10. At the x:\ia64\system32> prompt invoke the installation menu by entering txtrestore.
A Warning message appears stating that all data, including the partition table, will be lost
upon reinstallation.
11. Select Y to continue.
