So my work laptop is a Lenovo t440s running Win7 Enterprise.[/size]
I was playing around with trying to make a bootable USB so that I could run my own environment on my work PC with a quick reboot.[/size]

Anyhow, I tried to reboot the work laptop earlier and ended up with the following error:[/size]
Windows 7: Boot selection failed because a required device is inaccessible

I cant seem to get into system repair, or anything. I also don't have a CD drive in the laptop and finally to make issues worse, my only other machine (what im on now) is a Mac running El Capitan.[/size]

From all my reading I'm pretty sure its something to do with the MBR being messed up, but I just don't know how to fix it.[/size]

I've build a windows 7 virtual machine using VirtualBox and popped the HDD out and into a caddy. Not sure if this makes it any easier or not, but it meant that from in the virtual machine I could at least see the HDD in Disk Management.[/size]

Here's a screen shot:[/size]


I've tried booting the virtual machine install see if I can go down the repair route that way but it just doesn't see the HDD or windows installation.[/size]

Any help will be massively appreciated and might just save my ass.[/size]
