Run Startup Repair. Reboot. See if Win7 starts.

If not Run Startup Repair again. Reboot. See if Win7 starts.

Boot free Partition Wizard bootable CD, post back a camera snap of your maximized Disk Management drive map with listings so we can see the listings.

Once confirmed that System Reserved is marked Active, click on HD# to highlight it, from Disk tab select Rebuild MBR, Apply. Reboot to see if it starts.

There is no reason to format the deleted partition now.

Confirm that System Reserved is marked Active, either by using Diskpart Detail Partition command on the partition, or using free Partition Wizard bootable CD as I just wrote.

Did you change Active flag with PW CD? Did it accept Rebuild MBR command when applied?

Boot back into PW CD, confirm System Reserved is marked Active then again click on the DIsk # to highlight it, run Rebuild MBR from Disk tab, Apply. Close window and reboot.

If it fails again, boot Win7 DVD Repair console or Repair CD, run Startup Repair repeatedly with reboots until WIn7 starts up.

gregrocker , Thank you very much for your help . I have solved the problem . I use Partition Wizard and ı try What you suggest . But ı make 'Partition which contains Windows' active than I apply startup repair from Recovery DVD and fixed it
I was confused about partition . There are two partition about my instest . One of is called System Reserved (about 100 MB) , other is partition where My Orginally Windows installed(about 210 Gb). This time I make partition Windows locete active Then That is Ok .
I am still dont know What the partition called System Reserved is ???????

System Reserved partition is the normal Win7 boot partition. However it can become corrupted so if it didn't repair after Rebuilding MBR with PW CD and running Startup Repair, then the next step is to try marking Win7 partition itself Active to do the same steps.

These steps are included in this tutorial to Troubleshooting Windows 7 Failure to Boot - Windows 7 Forums. However since the corruption likely came from GRUB boot loader and not a virus I was skipping ahead and giving you a key step manually:
Quote:
8. As a last resort boot free Partition Wizard bootable CD to ... Make sure C or the 100mb System Reserved partition (preferred) is marked Active, then click on HD to highlight it, from Disk tab select Rebuild MBR, Apply. If Windows 7 doesn't start and you restored Active flag, run Startup Repair 3 Separate Times. If marking 100mb Active fails to Repair x3, then mark Win7 partition itself Active and try above steps again.
In this case skipping ahead worked since Win7 partition accepted the System boot files. If you'll post back one more screenshot of Disk Management we can make sure there are no possible problems.
