Windows 7: Win 7 no longer boots after removal of XP.

01 Nov 2009   #1

Windows 7 Ultimate.
Win 7 no longer boots after removal of XP.

Hi all,

I did have the following setup, on a single drive, two partitions:

345GB: Windows XP (installed first)
120GB: Windows 7

I've made a slight mistake I've deleted the partition which hosted the MBR for my dual boot setup.
Basically, I have a single hard drive split into two partitions. I thought that I was thoroughly satisfied with Windows 7, so I decided to delete the partition which XP was sitting on. Little did I realise/remember at the time, but the XP partition held all the boot information, thus rendering my newly formed single partition unbootable. I booted GParted to ensure that my partition was intact, and it showed the following:

/dev/sda1 Extended 465GB LBA
/dev/sda5 NTFS 465GB Boot
(I manually flagged /dev/sda5 as 'boot')

This all appeared normal to me, so I put my Windows 7 disc in and attempted the various repair options. In my experience (with XP), FIXMBR from the command prompt usually fixes the issue, in this situation it hasn't. I've also tried 'BootRec.exe /fixmbr' & 'BootRec.exe /fixboot'. None of which seem to work.

My last attempt at fixing this was using the 'Startup repair' option on the Windows 7 disc. This hasn't worked either.
Can someone perhaps kindly offer me a solution? I'd rather not reinstall Windows.

Hello jameswh. You definitly fried your XP install and seriously hurt your 7 install.

At this point you have done just about everything I would have suggested. SO!

Boot your 7 disk get out your product key and sit back and have a party.

Its windows 7 re-install time.

Oh really? Well, that's a shame. Oh well - it's completely my fault, so I guess I'll live with the consequences. : )

I assume I'm able to do a repair install by booting FROM the Windows 7 DVD? I can see that it's possible to do it within Windows, but cannot find any information about the possibility of doing it directly from booting the DVD.

1.Before proceeding keep in mind that you need a Windows DVD.
2.Boot from your Windows DVD.
3.At the first prompt (the one asking you the language to install, time and currency and Keyboard or input method) click next without any doubt.
4.At the second prompt, in the bottom left part of the screen you should see a link like this: Repair your computer. Click on it.
5.At this point the system will attempt to spot your Win7 installation directory. If you have got more than one, select the right one. Now click Next.
6.You should now be able to see a window called System Recovery Option.
7.Click Startup Repair.
8.The system will try to repair your Install. After that it will prompt you to reboot your computer.
9.At this point you should effectively be able to reboot your computer without any issue anymore

ALSO depends on how you removed XP you might boot to command. run as admin and check bcdedit --- see if it can find {bootmgr}.

If it can find {bootmgr} you might try:
bcdedit /export X:\Boot\bcd {enter}
depends on where your Win7 is

This is a problem as my Windows installation isn't actually visible at this point. : \
