Error Message

Claude's workspace (Cowork VM) fails to start on HP EliteBook X G1i 14" (Intel Core Ultra, "Next Gen AI PC"). The underlying cause is that the entire Hyper-V virtualization stack is non-functional on this machine, not just Cowork. WSL2 and Windows Sandbox fail with the same root error (0xc03a0014). This persists across a completely fresh Windows 11 Pro installation. Error chain Initial error from Claude UI: After manually placing sessiondata.vhdx (created on a different machine, see below), the error advances to: Failed to initialize with error 'The system cannot find the path specified.' (0x80070003) Error code: Wsl/InstallDistro/Service/RegisterDistro/0xc03a0014

  • Manually created sessiondata.vhdx on a different machine and copied it to the bundle folder, advances error but VmBus then fails Claude workspace should detect that Hyper-V is non-functional at install/first-launch time and surface a clear error explaining that Intel VMD must be disabled (with guidance for users on hardware where it can't be disabled), OR

Error Messages/Logs

Root Cause

Claude's workspace (Cowork VM) fails to start on HP EliteBook X G1i 14" (Intel Core Ultra, "Next Gen AI PC"). The underlying cause is that the entire Hyper-V virtualization stack is non-functional on this machine, not just Cowork. WSL2 and Windows Sandbox fail with the same root error (0xc03a0014). This persists across a completely fresh Windows 11 Pro installation. The root cause appears to be Intel VMD (Volume Management Device) preventing the Hyper-V storage and bus virtualization drivers from initializing. HP does not expose a VMD toggle in the BIOS on this model. Environment

Fix Action

Fix / Workaround

Workspace fails with progressively deeper errors as each manual workaround is applied, with no user-actionable fix available on this hardware class. Impact Claude's workspace feature is completely unusable on a flagship HP business laptop explicitly marketed as a "Next Gen AI PC." This likely affects every HP EliteBook shipped with Intel VMD enabled and no BIOS toggle, potentially a significant portion of current-generation business hardware.

What's Wrong?

What's Wrong?

Claude's workspace (Cowork VM) fails to start on HP EliteBook X G1i 14" (Intel Core Ultra, "Next Gen AI PC"). The underlying cause is that the entire Hyper-V virtualization stack is non-functional on this machine, not just Cowork. WSL2 and Windows Sandbox fail with the same root error (0xc03a0014). This persists across a completely fresh Windows 11 Pro installation. The root cause appears to be Intel VMD (Volume Management Device) preventing the Hyper-V storage and bus virtualization drivers from initializing. HP does not expose a VMD toggle in the BIOS on this model. Environment

Hardware: HP EliteBook X G1i 14" Notebook Next Gen AI PC CPU: Intel64 Family 6 Model 189 Stepping 1 (Core Ultra) BIOS: HP X90 Ver. 01.04.01 (06/03/2026) OS: Windows 11 Pro (fresh install, reproduced across two separate installs) Claude Desktop: v1.2581.0.0

Error chain Initial error from Claude UI: Failed to start Claude's workspace failed to set session disk path: session disk not found: C:\Users<user>\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\vm_bundles\claudevm.bundle\sessiondata.vhdx After manually placing sessiondata.vhdx (created on a different machine, see below), the error advances to: HCS operation failed: failed to create compute system: HcsWaitForOperationResult failed with HRESULT 0x80070003 'cowork-vm-<id>' Microsoft VmBus (Instance ID D41A1872-3740-41CE-A1EE-4522AB82F991): Failed to initialize with error 'The system cannot find the path specified.' (0x80070003) Diagnosis: Hyper-V stack is entirely absent None of the core Hyper-V drivers load, despite all optional features being enabled and the .sys files being present ``` in C:\Windows\System32\drivers: powershellPS> sc query vmbus # returns nothing PS> sc query vsmb # returns nothing PS> sc query storvsp # returns nothing PS> sc query vhdmp # returns nothing PS> driverquery /v | findstr /i "vmbus vsmb storvsp vhdmp"

no output

Any attempt to create a VHDX on this machine fails with:
A virtual disk support provider for the specified file was not found. (0xC03A0014)
This affects New-VHD, diskpart create vdisk, Disk Management GUI (diskmgmt.msc), and direct calls to virtdisk.dll!CreateVirtualDisk.
WSL2 fails identically:

PS> wsl --install --no-launch A virtual disk support provider for the specified file was not found. Error code: Wsl/InstallDistro/Service/RegisterDistro/0xc03a0014

**What I've already tried**

- Full fresh Windows 11 Pro reinstall (issue persists)
- Enabled all virtualization Windows Features: Microsoft-Hyper-V-All, VirtualMachinePlatform, HypervisorPlatform, Containers, Microsoft-Windows-Subsystem-Linux
- Verified VT-x and VT-d enabled in BIOS
- Set FsDepends and vhdmp service Start values to 0 (Boot) per Microsoft KB, values persist through reboot but drivers still don't load
- sfc /scannow: no integrity violations
- pnputil /add-driver vhdmp.sys /install, returns "Added driver packages: 0"
- net start vhdmp, reports success but driver is not actually running
- Manually created sessiondata.vhdx on a different machine and copied it to the bundle folder, advances error but VmBus then fails
- Verified Claude's MSIX path resolution is correct, the service reads and writes to C:\Users\<user>\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\vm_bundles\claudevm.bundle\ as expected
- Searched BIOS for VMD / "Volume Management Device" / "Configure Storage Controller for VMD", option does not exist on this HP model

**Behavior**

Workspace fails with progressively deeper errors as each manual workaround is applied, with no user-actionable fix available on this hardware class.
Impact
Claude's workspace feature is completely unusable on a flagship HP business laptop explicitly marketed as a "Next Gen AI PC." This likely affects every HP EliteBook shipped with Intel VMD enabled and no BIOS toggle, potentially a significant portion of current-generation business hardware.

### What Should Happen?

Claude workspace should detect that Hyper-V is non-functional at install/first-launch time and surface a clear error explaining that Intel VMD must be disabled (with guidance for users on hardware where it can't be disabled), OR
Claude's Cowork pipeline should create sessiondata.vhdx via a code path that doesn't depend on the host's vhdmp driver being loadable, 
OR
Anthropic should document supported/unsupported hardware configurations, specifically whether Intel VMD-locked laptops (common on newer HP EliteBooks, Dell Latitudes, Lenovo ThinkPads) are supported at all.

TL;DR

The issue can be worked around by disabling Intel VMD (Volume Management Device) in the BIOS settings, if available, or considering alternative hardware that does not have Intel VMD enabled without a BIOS toggle.

Guidance

  1. Check BIOS settings: Look for an option to disable Intel VMD (Volume Management Device) in the BIOS settings. If available, disable it and try running Claude's workspace again.
  2. Alternative hardware: If the BIOS does not have an option to disable Intel VMD, consider using alternative hardware that does not have Intel VMD enabled without a BIOS toggle.
  3. Contact HP support: Reach out to HP support to inquire about the possibility of a BIOS update that includes an option to disable Intel VMD.
  4. Documented hardware configurations: Check the official Claude documentation for supported and unsupported hardware configurations, specifically regarding Intel VMD-locked laptops.

Notes

The provided logs and error messages suggest that the issue is related to Intel VMD preventing the Hyper-V storage and bus virtualization drivers from initializing. Disabling Intel VMD or using alternative hardware may resolve the issue. However, without a BIOS toggle to disable Intel VMD, users may need to explore other options.

Recommendation

Apply workaround: Disable Intel VMD in the BIOS settings, if available, or consider alternative hardware. This is because the issue is caused by Intel VMD preventing the Hyper-V drivers from initializing, and disabling it or using alternative hardware may resolve the issue.
