Solved Cannot boot my windows after using GParted

please give a summary:
  • how did you do "startup repair"? form repair disk, form installation dvd or from F8 and then "repair your computer"?
  • power on your computer and tap F8 multiple times with about 1 second in between. What happens?
i did "startup repair using installation dvd. on startup, when i press F8 multiple times, nothing happen.

if you ust power on your computer, you see a BIOS screen. What happens afterwards? No menu, no starting windows, no winload.exe error anymore? Tell me exact what happens. and after how many seconds
i can see the BIOS screen. after the BIOS screen appeared, there is nothing on the screen except blinking cursor.

OS
Windows 7 Professional 32bit
Steps that i applied when i use GParted to solve this problem:
  1. select the Windows partition and click on "resize or move" option.
  2. in the resize window, drag the partition to the left.
  3. in the "free space preceeding (Mib)" option, set it to minimum 1MiB. not 0MiB.
  4. and click on "resize or move".
  5. when processes completed, restart the pc.

i booted the Windows install disk
  1. on the welcome screen, click next.
  2. Windows repair will automatically detect the problem and click the "restart and repair".
  3. after restart, the Windows Memory Diagnostic Tool launched automatically. then the checkdisk will be launched.

now, i'm back to my Windows. :D

thank you to Kaktussoft who try hard his best to help me. i appreciate all your words!

startup repair is needed if you change start sector of os-partition.
checkdisk is performed automatically (normally) the first time the partition is booted.
1Mib boundary is default.

So I don't understand.

but it's working now...

Sounds to me like the drive that has the Win 7 installation is not first in the Boot order in the BIOS.
