Help with dual boot after bios flash

alexp82539 · 01 Mar 2011

Hi there,
I have a Toshiba satellite L450D laptop (AMD Sempron SI-42 – 2.GHz and 3 GB RAM DDR2) which up until recently was running a dual boot of Windows XP Pro SP3 (x86) and Windows 7 Home Premium (x64). It was all running fine until I flashed my BIOS, (which was successful) and neither version of Windows would start. I got to Windows boot manager and then upon selecting an OS it would come up with Windows would not start. I read somewhere that the BIOS update may have changed the addresses of something (I’m not too sure about this bit) and so performed a fresh install of Windows 7. This worked perfectly, Windows 7 runs fine, and I am still getting to Windows Boot Manager upon start-up. When I select Windows 7 it boots fine and if I select XP the same thing happens as before – Windows could not start. I then proceeded to re-install XP, and the setup loads up until the final loading message (setup is starting Windows I think) and then I get a blue screen with the following message:
“A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the 1st time you have seen this stop error screen, restart your computer. If this screen appears again, follow these steps. Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption and then restart your computer. Technical Information: ***STOP: 0x000000713 (0xF78D2524, 0xc00000034, 0x00000000, 0x00000000)”
I have run CHKDSK /F from a Windows 7 CMD and this returned no errors although it did check the C drive??
Any ideas or suggestions would be greatly appreciated as I am at a complete loss for this one. Many thanks in advance

A good way to check would be to use a piece of Freeware called EasyBCD 2.0, this basically Checks your HDD for any Installations and tells you the current boot log, and can see what OS's you have installed.

If you could Link and Image of the Summary tab i would be able to help you a bit more.

Hello alexp82539, welcome to Seven Forums!

In the BIOS it may be the SATA/IDE controller has changed from IDE to AHCI, look in the BIOS for something like 'storage controller' for this setting.

If it's set as AHCI you may need to slip XP SATA drivers into the XP installation media to get XP to install successfully; have a look at this tutorial at the link below and be sure to post back with any further questions you may have and to keep us informed.

Hi, thanks for the reply, i looked in my BIOS settings and sure enough there it was. I had a closer look and it allowed me to use something called compatibility mode instead of AHCI, so i used this. When i started 7 it installed a load of drivers automatically, then proceede to install XP and it worked 1st time no problems, so thanks a lot for your help! you've pretty much saved my AS Levels!!
Thanks Again!!
