This thread shows a classic HAL failure on a Toshiba Satellite A10 (PSA10C-05hvm): Windows reports "<Windows root>\system32\hal.dll" missing/corrupt and the machine won’t boot recovery media or let the OP change boot order in BIOS. Replies from , and covered boot-key and drive tricks; if those quick attempts didn’t help, the safest, most reliable path is to (A) rescue data first, then (B) repair the boot files and MBR offline.

What the error means: hal.dll is the Hardware Abstraction Layer Windows loads before the kernel. If it’s missing or the disk/boot structures are damaged, the OS can’t start. The repair goal is to restore a correct hal.dll and ensure the MBR/boot sector and filesystem are healthy.

Practical, non‑redundant options (ordered by how minimally invasive they are):

  1. If you can boot a Windows install/repair disc: use the Recovery Console / Repair Environment and run (replace drive letters as needed)

    fixmbr
fixboot
chkdsk /r
expand D:\i386\hal.dl_ C:\WINDOWS\system32\hal.dll

    Or, from a WinPE/repair prompt:

    sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

  2. If the laptop won’t boot any media or BIOS is locked: remove the laptop HDD and attach it to another PC (USB‑IDE/SATA adapter or install as a secondary drive). From that host you can:

  • Run chkdsk against the laptop volume.
  • Copy/expand hal.dll from the host’s matching Windows media into the laptop’s \Windows\System32.
  • Image the drive first (dd/Clonezilla) if the disk is failing, then attempt repairs on the image.
  1. If you only need files: boot a Linux live USB on any machine and copy user folders off the laptop disk.

Cautions and final notes: never grab a random “hal.dll” from an unknown website — use original installation media or a trusted source. If the BIOS truly prevents changing boot order, check for a supervisor/password lock or service‑only lock (Toshiba service may be required). If those repair attempts are uncomfortable, have a local technician image the disk and attempt the Recovery Console commands. After recovery, create recovery media and a disk image to avoid the same scramble.

im using a toshiba R/10, to get to your cd tray you have to change the bios by pressing esc f1 or f3.

to just boot from dvd press f8-f12 repadely as soon as the computer starts.

i tried f1 or f2 but it is not responding...when i tried f12 i heard beeps but it did not boot to the dvd drive

Member Avatar for njzillest

well hit all the F buttons at the same time. It should take you to a screen with four icons on the bottom. Go to the right, where approximitly in the middle where the cd is.


if that doesnt work, i guess you have to call those untrained technitions :-/

Hi I am having problems with my Toshiba, seems to be really unstable
loosing key startup files, even after a re-install.
Hope this is not to late, if your recovery cds are anything like mine. Put the 1st cd in the drive, power down, then power up holding the C key down and it will take you into the recovery program.

What is have is a very short methods to force boot to CD-ROM
FIIRST: Remove the hard sidk from the laptop.
The hard is a pluggable device which you can plug in and plug
out of the laptop.

SECOND: Put on the computer without the hard disk and do not place
any bootable CD in the CD-ROM.

This will force the bios agent to change the boot priority from
hard disk to CD-ROm for good.

When it boots up it will give an IDE0 Error and restart the
you a invalid system disk. Plese insert valid system disk.

THIRD: Place the bootable CD or recovery cd, turn off the laptop.
Then plug back the hard disk to the laptop and turn off the
the laptop.
You don't need to press anything and it first boot straight from the
CD-ROM and you are done.
