Hello Everyone.

I have a Toshiba Satellite L300 laptop running windows xp professional (downgrade from vista). Everything was running fine until I stupidly updated the BIOS from version 1.80 to 2.10 and no my laptop wont work it wont get to the windows load up, it wont even go to safe mode or reinstall operating system. I know the issue is upgrading the bios from 1.80 to 2.10 but how can I if possible change back to 1.80 or how can I fix this problem. A free solution preferred but would appreciate if I had to take it to a shop or what might need replacing if i cant change the bios. I don't know about the bios i know a fair amount on pc's

All help will be really appreciated.

Thank you in advance

The BIOS is a Insyde H2o that's all i know about the BIOS if you need more info on laptop i can give it to you.

Again please help and i appreciate all support and help i can get.

Was the BIOS updation process (1.80 to 2.10) interrupted in anyway?

Updating the BIOS is NEVER RECOMMENDED unless you have a specific compatibility/hardware issue that is addressed by the update.
If something goes wrong during the upgrade/downgrade process of the BIOS, you'll have an expensive paperweight for yourself.

However, you can always take it to the Service Centre and get it checked, replacing the motherboard if necessary.

If you still want to attempt downgrading, go through these links:

Hello. Thank you for taking you time to respond. The update was not interrupted in anyway it came up updating erasing and writing new data and restart at the end automatically and then it loads back up with blue screen.

I would like to try get it fixed myself to try save money but if I can't fix it i shall take it to be repaired.

Do the 2 links below downgrade my laptop bios to 1.80 as I don't understand much about the bios with what one to download if that makes sense.

Thank you

**Just been reading forums whilst waiting and i found this i not sure if i can use it to downgrade to 1.80 can someone verify

FWIW, flashing BIOS can be a little tricky sometimes....If it ain't broke ...Don't fix it!!!

You need to select a version that you can make a bootable disk from...Floppy, CD, or possibly USB...Download that version...Put it on bootable media...Load it and start your computer...

Hello. I had a response from Toshiba and it has fixed the problem. They told me to do the following

If you have been experiencing the problem since upgrading the BIOS then potentially the fault could be caused by incorrect BIOS settings on your machine.

The error message that is being displayed (0x0000007B) can be caused by a missing or bad boot sector. This is the part of the operating system that is accessed when the laptop is trying to load Windows.

What we would suggest is to load to the BIOS by starting the laptop and pressing F2 and then loading the BIOS setup defaults by pressing the F9 key. Then navigate to the ‘Advanced’ tab by pressing the right arrow key and navigate to the ‘SATA Controller Mode’ setting (if applicable).

This will need to be changed from ‘AHCI’ to ‘Compatibility’. Once this has been done, pressing F10 will save these changes and restart the machine.

If you can load to the BIOS this would suggest that the BIOS update was successful and that the Hard Drive is at fault. If this is the case then we would suggest running a full system recovery as detailed in the previous email.

Thanks for posting your solution...it seems that changing a single BIOS setting created/solved your situation.

No mate, those links were only to show the possibility and process of downgrading your BIOS.
You'll need to get the right version of the BIOS from the Toshiba Support website.

I joined only to promote this reply that saved my ass after almost 12 hours of looking for stranger and stranger solutions by every passing moment.

WHEN YOU UPGRADE YOUR BIOS ON A L300 (SATELLITE, and i guess this must be applicable to the whole satellite series at least); you need to change that 'SATA CONTROLLER MODE' setting to 'Compatibility'; and till its not done, HARD DISKS wont work no matter what you do.

I was about to flash my bios just before hopping onto this post..!
TOSHIBA SUCKS BIGTIME IN SUPPORT! but still, at least they gave a sensible reply to ChapperZHTID!
can sleep now..! :)

I am using the very same computer right now (Toshiba Satellite L300). It is currently running Windows 7 on the old BIOS. The fact that you can get far enough to have a blue screen means that the BIOS is working correctly. Newer BIOS'es have the SATA controller set to AHCI mode by default. From past experience I have seen that this works fine with Windows Vista and Windows 7, but anything older will get a blue screen no matter what it is booting from (CD, Hard drive, flash stick).It is very possible that the newer version of the BIOS is set to AHCI mode by default, preventing Windows XP from starting. I once had an Acer desktop that I could not install Windows XP on. I eventually found out that changing the SATA controller from AHCI to compatibility (IDE) mode fixed the problem. To fix this problem, press F2 as soon as you see the TOSHIBA logo to enter the BIOS. Look for a tab that reads something like "advanced" and go to SATA controller mode. Press enter and select "IDE" or "Compatibility" and press enter. Exit the BIOS and remember to save changes. Windows should now be able to boot without even re-installing.
