Task Sequence Failed: Error 0x8007000f

To fix Error 0x8007000f, you can manually format the hard drive and check if the network connection is stable. Here are the steps in detail:

1. Check the Network Connection: Before trying any other solutions, ensure that the network connection is stable and accessible. Check if the cables are connected, and the network share location is accessible from the device running Task Sequence.

2. Manually Format the Hard Drive using the Diskpart command: You can fix Error 0x8007000f by formatting the hard drive before continuing with Task Sequence. Run the following commands one by one in a Command Prompt window:

Diskpart

Select disk 0

Clean

Convert gpt

Create partition efi size=300

Assign letter=k (or any letter you want)

Format quick fs=FAT32

Create partition msr size=128

Create partition primary

Assign letter=c (if the C letter is not available, check if you have a USB key mounted)

Format quick fs=NTFS

Exit

Restart your device, try running the Task Sequence, and see if the error is fixed.

3. Change UEFI Boot Mode to Legacy BIOS Boot Mode: If deploying a Windows image configured to boot in UEFI mode instead of the legacy BIOS boot mode causes the Task Sequence error, change the UEFI Boot Mode to Legacy BIOS Boot Mode and see if the error is fixed.

4. Restore BIOS to its Default Values: If none of the above solutions work, restore your device’s BIOS to its defaults. A corrupted BIOS may cause the error 0x8007000f, failing to run Task Sequence.

In summary, Error 0x8007000f occurs when the Task Sequence fails to run due to issues accessing or copying files from a network share. To fix it, you can manually format the hard drive, check the network connection, change the UEFI Boot Mode to Legacy BIOS Boot Mode, or restore BIOS to its default values.
