Either boot to a bootable device that will give you access to a command prompt, or press F8 before selecting the Task Sequence and run:
diskpart
select disk 0
clean
create partition primary
assign letter=c
format quick fs=NTFS
Exit
A reboot may be required to use the Task Sequence.
Why does this error occur? The TS is looking for an NTFS drive. If the TS fails to find an NTFS drive, an access error is returned. This will often happen when the drive has BitLocker enabled on it. If you want to examine the details of the task sequence failure, look into the smsts.log file.
