After working on USB3 attachment issues with Win7 VMs on my laptop, I have started to get this error message on booting up:
What is an “environment block”? How do I remove the cause of this problem?
Gparted shows that I haven’t run out of storage space on the drives - I still have most of the space free.
Pressing any key to continue, allows the boot-up to proceed normally, though it will continue boot-up itself after a pause at this screen for some seconds.
Many thanks for your advice…
