I intended to install windows xp sp3, but after loading the setup files and about to start installing windows I get the following error message '' ........ STOP: 0x0000007B (0F789E63C, 0xC0000034, 0x00000000, 0x000000000). I seached knowledge based at support.microsoft website but no that solution. kindly suggest solution and advice accordingly.

STOP: 0x0000007B during the "Setup is loading files" phase means Windows setup lost access to the boot drive (INACCESSIBLE_BOOT_DEVICE). On notebooks this most often happens when the XP installer doesn't have a suitable storage-controller driver for the SATA controller (AHCI/RAID vs IDE). This matches 's symptom of an immediate 0x7B before formatting. (learn.microsoft.com)

Fast, low-risk first step: enter the HP BIOS (Esc at boot, then F10 on most HP notebooks), find the Storage/SATA or SATA Operation option and switch the controller from AHCI/RAID to IDE/Compatibility/Legacy (or disable AHCI). Retry the XP install — that normally lets XP's built‑in IDE driver see the drive so setup can continue. Note: changing controller mode can make an existing OS unbootable and disables AHCI features (NCQ, hot‑plug), so back up any data first. ()

If keeping AHCI is required, supply the correct XP "text‑mode" AHCI driver during setup: either load the vendor's F6 driver from a floppy when prompted, or slipstream the text‑mode driver into a new XP SP3 installation ISO (nLite is the common tool). Critical points: get the chipset vendor's XP F6 driver (INF/SYS/CAT), add the driver as a text‑mode/txtsetup driver (not just a PnP driver) and recreate the bootable media. XP's F6 mechanism expects a floppy (or a compatible USB‑floppy) so slipstreaming is usually the practical option today. (prime-expert.com)

Extra checks if the problem persists: burn a fresh XP SP3 ISO, try a different optical drive, run the HP diagnostics/drive self‑test and update the BIOS. 's BIOS-mode suggestion is the quickest diagnostic; if that works but AHCI is needed later, use slipstreaming so the final install can run in AHCI without the 0x7B.

do you format the c drive for ntfs?

do you format the c drive for ntfs?

I haven't reach that stage. When I was prompted to boot from CD, I pressed enter. It was during loading the setup files that I got the above error message. So haven't reach formatting stage.

you have to get into BIOS, find the SATA Menu and change in to Legacy mode (or ATA mode).

OR just disable AHCI. (in AHCI menu)
