Boot camp Windows 7 failed to boot after shinking

Recommended Posts

My Windows 7 installation failed to boot after I shrink it with GParted.

I have already sync the GPT and MBR.

Everytime I select the Windows partition to boot, a black screen with a blinking cursor appears. If I have a bootable disk inserted in the SuperDrive, my Mac just starts booting up the disk after few ten seconds.

 

I have attempted many times using Windows Repair Disk to fix the problem. The repair console found the Windows installation.

However, bootrec /fixboot, bootrec /fixmbr, bootrec /rebuildbcd these commands have been tried for numerous times but don't help.

chkdsk show no problem.

I have also tried Repair Disk with Disk Utility and it said the disk is normal.

I have tried rebuild the MBR with gdisk without success.

 

Does anyone have any idea to solve the problem? Thank you in advanced!!!

 

EDIT: I am tri-booting (Mac, Win 7, Ubuntu) before the shrink and it worked. It just breaks after this recent shrink.
