We boot into Windows again and arrive at the login screen. We have now renamed a copy of command prompt and associated it with the sticky keys functionality. Now make a copy of cmd.exe and rename this copy to sethc. Use the open feature of text editor to navigate to Windows/system32 directory and rename sethc to something random. This will open the report in text editor. Once done, click view report details and click on the link down below that ends in a. Take advantage of the repair mode and wait for it to attempt the repair (this takes several minutes). Restart Windows and hard reset (long press the power button) as the Windows icon appears on the screen. Turns out the old renaming sethc, copying command prompt executable and renaming it sethc.exe trick still works! Here’s how it goes.

So now I had to find a way to reset Windows 7 password.
Error when partitioning mac for bootcamp password#
I forgot the Windows 7 password since I hadn’t logged into for a while (I don’t really use this Windows partition for another but to play some games and I couldn’t even do that with the Bootcamp boot entry missing). Press and hold the ALT key at boot time and the Bootcamp boot entry should now appear in the MBR. Place EFI GPT (0圎E) partition first in MBR (good for GRUB)? yĮxit the terminal at this point and restart Mac. Use the gdisk tool as follows to restore the partition entry: sudo gdisk /dev/disk0 Now that we are equipped with the knowledge of what the disk number is for the Bootcamp partition, we can begin the procedure of restoring the Bootcamp entry in MBR. You can also verify this in Disk Utility where clicking info about the Bootcamp partition should show something like disk0s5,also note that the bootable flag is likely set to no at this time. Locate the Bootcamp partition and notice the partition number assigned to it. After installing this tool, bring up a Terminal window and execute: sudo gpt -r -vv show disk0 We will use this tool to derive some disk information.
Head over to sourceforge and obtain the latest copy of gptfdisk: We can now begin restoration of the Bootcamp boot entry. If it is, the file explorer can be used to verify that the files within the Bootcamp partition all still exist. The Bootcamp partition should still be there. This can be verified by logging into the alternate OS (Mac OS X) and using Disk Utility to look at the partition structure. However, the partition still exists and the files within the Bootcamp partition are untouched. The problem is that when the disk structure is modified, the Bootcamp boot entry is lost from the MBR. On an unrelated note, this write up also involved resetting the Windows 7 password since I realized that I forgot the Windows password. It took a series of steps to get the Bootcamp partition boot entry back into the MBR and so I decided to document the procedure.

I recently installed the latest copy of Mac OS X and lost the Bootcamp Windows partition boot entry from the MBR (Master Boot Record).
