Then, like a bad dream wrapped in a QR code, the screen flipped to blue: Your PC ran into a problem and needs to restart. We’ll restart for you. The VM restarted. Same blue screen. Loop. Loop. Loop.
She killed the loop and powered off the VM. Her mind raced through the possible causes. She hadn’t changed any boot order settings. No new disks. Just a standard Windows Update. But this error— inaccessible boot device —meant one thing in VMware: the virtual hard disk controller had changed, or the driver for it had vanished into the digital abyss.
She pulled the VM’s logs from /var/log/vmkernel.log on the ESXi host. Buried in the red text: “Device ‘scsi0:0’ is not ready. Access to device failed.”
Sarah attached the Windows 10 ISO to the VM’s virtual CD-ROM. She booted into the recovery environment— Repair your computer > Troubleshoot > Command Prompt . Then she ran the cavalry:
Outside, the night was quiet. But inside the datacenter, one little VM was booting happily again—unaware it had almost died for a driver’s vanishing act. Always keep a recovery ISO and driver floppy image nearby. In the world of VMware and Windows 10, the boot device is never truly inaccessible—it’s just waiting for the right driver to show it the way home.
The Blue Screen Threshold
She exited the command prompt and clicked “Continue to Windows 10.”
“The virtual disk is fine,” she said, checking the datastore. “So the guest can’t see the boot disk.”
