SCCM – Task Sequence – Error: 0x80070490

Recently I have been doing a lot of SCCM work and deploying tests.
Some of the clients I tried to run a task sequence to, gave me the following error 0x80070490.

I figured out it is because there where no partition (C:\) that the image could be stored to temporarily, so when the error is displayed:

  1. Press “F8“.
  2. Run “diskpart.exe“.
  3. Select the disk with “select disk 0“.
  4. Clean the disk with “clean“.
  5. Create a new primary partition with “create partition primary“.
  6. Set it to active with “active“.
  7. Format the partition quick to NTFS with “format fs=ntfs quick“.
  8. Assign the partition a letter with “assign letter=C:“.
  9. Now quit the application with “Exit“.

Reboot and try to run the task sequence again, if it fails once more you may need to look in the actually task sequence it self for errors.

    Hi! This works so well, but, How could I fix it from the task sequence?
    I do not want to do it with all the systems one at a time.

    Could you please help me?

    Depending on if this can’t expand due to a disk with Bitlocker/your TS design, you may need two partitions.

    Select disk 0
    Convert gpt
    Create partition efi size=300
    Assign letter=k (or any available letter you want)
    Format quick fs=FAT32
    Create partition msr size=128
    Create partition primary
    Assign letter=c (at this step if the C letter is not available, check if you have USB key mounted)
    Format quick fs=NTFS
