Windows 7: Unable to start up Windows 7 & Windows 7 System Recovery tool

Unable to start up Windows 7 & Windows 7 System Recovery tool

Hello all,
I've had two partitions, one with XP and another one with Windows 7.
At boot runtime I could choose one of the two from the Window boot menu.
Later I installed a linux distro (debian) into another partition with the Grub support.
All worked fine. I could start linux or the Windows boot menu from Grub and so on.
All worked fine until today when while working on partions I accidentally deleted the linux one.

Now at start up it runs grub with an error (error 22) without showing the usual OS menu.

I tried also to recover the Windows 7 partition using the Windows 7 dvd installation.
The start up recovery tool said it fixed all things. But rebooting I'm still getting the same grub error.

How can I solve this problem and restore the Windows 7 boot menu?

Thank you

Boot into Windows 7 DVD System Recovery Options or Windows 7 System Repair Disk to Mark Win7 or it's 100mb System Reserved Partition (preferred if you have it) Active.

Then run Startup Repair - Run up to 3 Separate Times until Windows 7 starts and it's boot partition holds the System Active flags.

If this fails when System Reserved partition is marked Active, move the Active flag to Win7 partition itself and then try the 3 repairs again.

Be aware that sometimes GRUB can corrupt Windows 7 beyond repair when on the same HD. If problems persist I would delete it completely and then for any future Linux Dual Boots use separate HD's booted only via BIOS, or Dual Boot - Windows 7 and Linux - Windows 7 Forums.

If all else fails it may be necessary to wipe the boot sector of interfering code using Diskpart Clean Command before Clean Reinstall - Factory OEM Windows 7 which steps are same for retail.

Thanks all.

gregocker, I followed the theog's instruction about the command line options and it worked fine.
However, it booted directly into Windows 7 without showing me the boot menu: there was XP too somewhere.
From Windows 7 I ran EasyBCD and added a boot entry for Windows XP.
Now it works perfectly as before.

Again, thank you guys.

Those dated manual Commands are all automated in Win7 Startup Repair, but it also tests and fixes other parameters like whether you have the Repair console now on the F8 Boot Tools menu. Doubtful. It can also sometimes restore the Dual Boot.

To restore the Dual Boot manually, install EasyBCD to Win7 to delete any previous XP listing, add XP.
