Specs: Windows XP
Hi
I have a Toshiba satellite laptop with winxp / vista dual boot on a partitioned drive.
I received a physical memory dump / blue screen of death in winxp when trying to play a dvd that the system / dvd player didn't get along with.
Now the computer will not reload to the dual boot menu ... it shows the initial Toshiba flash screen then goes to black with blinking cursor.
From reading various posts, I am thinking that I will need to repair the xp installation with the original cd, however, if I do this will it keep the dual boot functionality or will this be overwritten?
Any help with the best way forward that will save my data and keep the dual boot in place will be much appreciated??
Many thanks!!

Hi,
Yes you can repair the XP boot by starting with the XP CD and entering the Recovery console, type fixboot, press return you will get a warning about the existing boot sector but continue with the repair. This will remove the Vista installed BCD, so you will boot straight into XP. You can then download Vista-Boot Pro to restore the dual boot option. There is a useful help section to guide you through this bit! The download can be found here... use server 2, server 1 was offline!

Have been unable to locate my XP Pro disc ... the question now is: do I need my original XP Pro disc or will I be able to restore / recover with another disc??

I have been able to boot off the DVD drive with the Vista disc and go to a DOS prompt but the Win XP partition does not show a windows directory - does this mean that the directory has been erased or is just hidden?

Thanks again ...

Hi,
You should be able to use any XP cd to do the repair, but the Windows folder is not hidden! Its hard to believe that playing a DVD could cause this much damage! Can you see anything on the XP partition?
You could try starting from the Vista disc and follow the steps here...

then recover any retrievable data from the XP partition via Vista. You might need to take ownership of the My Documents folder to be able to open it. If the folder, which is in the Windows directory, cant be found, you could run this program
http://www.piriform.com/recuva/feat...
It is a very good recovery program that will recover any recoverable data, tell it do do deep scan if you need to use it. Also don't install it or save data to the partition you are trying to recover files from!
Another way of saving data, if you have an external USB hard disk would be to download, and burn to a cd or dvd (depending which one you downloaded), one of the Linux distro's. you could then save your data to the external disk then do a fresh install of Windows.

I hope that something I've mentioned helps! Good luck.

Sorry, I forgot to mention that if you download a Linux distro you need to start the computer from the CD or DVD. You will be running the 'Live' version meaning nothing is installed to the hard drive, the operating system is run from the optical disc.

Hi bazzab ... thanks for your instructions. Hopefully I can make some progress.

Yes I can see some directories (and the files below them) via the prompt command, just not the ones mentioned which contain most of the data.

I did use a linux disc given to me by a friend, Knoppix, but couldn't read the c: drive with this at all.

I think the DVD was corrupted or warped ... it certainly made some weird sounds before shutting the system down, and has now been consigned to the garbage bin.

Hi again ... have made some progress with the manual repair of the vista bootloader which now gives me the dual boot menu and can now get into vista.

Unfortunately access is denied to the winxp c: drive.

I now at least have an error message when trying to load winxp which says the ntldr file is missing or corrupt.

As I can't locate my original winxp cd (which I think is deep in storage), if any winxp cd will do the repair and I can get hold of one then I should (fingers crossed) be able to get back into winxp before too long.

Thanks again for your help.

Can you see the XP installation from Vista?
If so you may be able to copy your files from there. As mentioned before, if the files are in My Documents, you will have to take ownership of that folder, then copy the files to a CD or external hard disk. The missing ntldr file does indicate that serious damage was done to XP, though why playing a DVD should do this is anyone's guess, unless the player was the root of the problem.
This might be of help but if you follow these instructions, will you lose the options of booting into Vista?

You mentioned you used Knoppix, I'm not sure if that distro supports the NTFS file system, I know Mint does, that's why I gave that link. If all else fails try running Recuva from Vista and see what it can recover, then save it to a medium not on the drive you are recovering data from. You may need to check the box 'Deep Scan'.
I wish you the very best of luck!
