Today I tried installing windows xp on a Toshiba L455-S5000.  This system comes  with Windows 7, but I wanted to downgrade to Windows XP.  And I got the blue screen and I recalled that windows xp does not detect most SATA controllers.  Therefore, I looked up on Toshiba’s support website and found that they do have an Intel Matrix Storage SATA HDD Driver.  You will need another computer with network connection, floppy disk, and a floppy drive.  YES, I did say floppy drive.  Windows XP will only recognize a floppy drive for this portion of the installation (I will explain further below).  I’ve downloaded the file and extracted the .exe file.  To do this you can extracted with any zip files.  I used winrar or winzip to extract this file.  After you have extracted the file you can put it on a floppy drive.  For additional downloads go to this link: http://laptopforums.toshiba.com/t5/Windows-Vista-Windows-XP/Downgrading-L455-S5975-from-7-to-XP-driver-issues/m-p/66429 Jamesbond2010 has these files under rapidshare.com to download and for additonal help.

The “Blue Screen of Death” can occur virtually at any time.  Issues with drivers, a hard drive issue, viruses and so on.  But this is a very specific type of blue screen error, bsod

  INACCESSIBLE_BOOT_DEVICE

  Setup cannot continue. Power down or reboot your computer now.
• You may also receive a “Stop 0×0000007B” error message during Windows XP Setup when the Setup program restarts during the installation process. When you receive a Stop error while the Setup program is running, you receive the second error message. To troubleshoot this issue, read the following four sections to determine if any one of the issues applies to you. If none of the issues apply to you, use the following general troubleshooting steps at the end of the article.

This is a very common issue with SATA hard drives if you do not have the correct drivers.  Normally, when you install Windows XP you will go through the process and before it reaches the repair or install windows options you will receive the blue screen. 

Here are the steps to have the correct driver:

1. First you will need to have a floppy drive, you don’t have one you can buy a usb floppy drive at any electronic store.  These normally will run you about $40-$80. 

2. Now place your disk in the floppy drive plug usb end to your computer.

3.  Place your Windows XP cd in your cd rom and start your computer.

4.  Make sure you have the cd boot first.

5.  During the start up of windows setup keep pressing F6 and soon you will have the option to select a SCSI or RAID driver.

6. You will need to press “S” to specify driver, after doing so you are given the option to choose your driver.  Normally you want to choose the one with AHCI if you are not using RAID or SCSI.

7.  after that you will need to just follow the steps and complete your installation.

and that is it, let me know if this is useful.
