ronyclau Posted May 21, 2013 Share Posted May 21, 2013 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.
