Recently when I tried to PXE boot to image a machine, when I boot and select my task sequence , I am given a TsmBootstrap.exe error. 

——- The error ——-

The file or directory c:\_SMSTaskSequence is corrupt and unreadable.  Please run the Chkdsk utility.

——- The error ——-

Now, I can’t deploy any task sequence from boot media without getting the error.


Solution :

The solution for the BAD computer is with “diskpart” to remove all partitions and create a new small with a clean bootable partition ‘C’.

The problem for the bad computer is that the folder C:\_SMSTaskSequence is already present, but it has gone corrupt and I didn’t had the permission to delete or rename this folder.

After erasing all partitions, it works again like a charm.


Hope it Helps ,
