Windows 7 Windows 7 and vista dual boot problems

[spirit523]

I have a 1TB hard drive divided into 2 partitions of 500GB each. On one partition I have installed windows 7, and on the other, windows vista. Several days ago I started getting a blue screen when trying to boot the windows 7 side. It occurs almost immediatedly after the splash screen. The automatic repair that windows tries to do is unsuccessful.

Since then I have been booting the vista partition. I could still access data files on the 7 partition. Today the vista partition doesnt boot either. The error message is something like Sata drive 0 not recognized. I checked the bios and it does exist. The windows installation disk for windows 7 is of no help. I select repair and it is unsuccessful. I select install, and the install disk doesnt recognize either partition. It only recognizes a drive x that it says has 30 GB in size.

I suspect the mbr is missing or damaged but dont know how to repair or get it back since even going to the command prompt on the install disk only allows me to go to drive X. In looking at drive X it looks as though it only has install files on it.

I dont know about the blue screen on the 7 partition but I suspect I did something to cause the vista partition to no longer boot. I dont even get to the startup screen that gives the dual boot option any more. I just get the "drive 0 not recognized" error message and the "press ctrl-alt-del to reboot".

Any thoughts or ideas? Thanks!

Scott, It sounds like you're encountering multiple issues with your dual-boot setup containing Windows 7 and Windows Vista. The symptoms you described point towards potential problems with the Master Boot Record (MBR) or the boot configuration settings. Here's a suggested step-by-step guide to troubleshoot and potentially fix the issues:

Steps to Try:​

1. Repair the Master Boot Record (MBR):
   • To repair the MBR, you can use the Windows installation disk.
   • Boot from the Windows installation disk, choose the language, and then select "Repair your computer" instead of installing Windows.
   • In the recovery options, select Command Prompt.
   • Type the following commands:

      bootrec /FixMbr bootrec /FixBoot bootrec /RebuildBcd

   • Reboot your system after executing these commands.
   []Check Disk and System File Checker:
   • In the Command Prompt from the Windows installation disk, run the following commands:

      chkdsk /f /r C: sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

   []Backup Data:
   • If possible, backup your important data from both partitions before proceeding with any repairs.
   []Check SATA Drive Connection:
   • Ensure that the SATA drive connection is secure. You could try reseating the SATA cables or switching to different SATA ports on your motherboard.
   []Partition Recognition:
   • If the Windows installation disk is not recognizing the partitions, it might be related to incorrect drivers. Try loading additional drivers during the installation process.
   []Test the Hard Drive:
   • Consider testing your hard drive's health using diagnostic tools to rule out any hardware issues.
   []Consider Professional Help:
   • If the above steps do not resolve the issue, it might be best to seek professional assistance or data recovery services.

     Additional Tips:​

   • If you suspect the blue screen issue on the Windows 7 partition might have triggered the problems, focus on resolving the Windows 7 boot issue first.
   • When attempting repair operations, ensure you are working on the correct partition, especially when using commands that modify the MBR. By following these steps, you should be able to diagnose and potentially resolve the boot issues affecting both your Windows 7 and Vista partitions. If you encounter any difficulties or need further assistance, feel free to provide additional details for more specific guidance. Good luck with the troubleshooting process!
