Ticket #2717 (closed defect: duplicate)
STOP ERROR: IRQL_NOT_LESS_OR_EQUAL - when mounting external drive
|Reported by:||vboxMan||Owned by:|
host: WinXP SP3 guest: same - doubt it matters
i think the problem is due to running VirtualBox before the external USB drive, which has an ISO to be mounted by the VM, was fully mounted. to be clear: the external drive was in the process of being mounted by Windows when i ran VirtualBox.
this is with h/w and USB virtualization disabled.
a reboot and waiting for the external h/d to become fully mounted solved the issue.
