BLKCACHE_IOERR while installing Lubuntu on USB flash drive

[ted-tanner]

I am attempting to install Lubuntu on a SanDisk USB Flash Drive and boot it via VirtualBox on a Windows host. To do this, I created a raw .vmdk file and linked it to my USB drive using the following command:

Code: Select all

VBoxManage internalcommands createrawvmdk -filename C:\path\to\file\disk.vmdk -rawdisk \\.\PhysicalDrive1 

I have "inserted" the Lubuntu .iso and Lubuntu boots up. When I go to install it, though, it takes me through the setup and I tell it to begin the installation. As soon as it begins, I get the following error:

An error has occurred during virtual machine execution! The error details are shown below. You may try to correct the error and resume the virtual machine execution.

The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_ACCESS_DENIED). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards.

Error ID: BLKCACHE_IOERR
Severity: Non-Fatal Error

I've booted from physical drives in VBox before and never had this error appear. How can I resolve it so I can install Lubuntu?
