windows bootcamp, print screen !!!

apparently ---

  • Capture Full Screen: FN+Shift+F11
  • Capture Front Window: FN+Option+Shift+F11
Note that on some larger Apple keyboards Boot Camp maps F14 as the printscr button instead, allowing you to just hit F14 for the full screen or Option+F14 to grab a window. Also, some keyboards label the function key as “fn” and the option key as “alt”.

booting from usb flashdrive on virtualbox OSX 10.7

OSX 10..7.4 , VirtualBox 4.1.18

importqnt note.. the reason i wanted to do this was to test the bootability of a usb flashdrive.. however, apparently being able to boot from such a drive in virtualbox doesn't give any true indication of booting a real computerrer.. oh well.

so.
install virtualbox extension pack to give usb2.0. not sure if this is necessary, but it maywell give a useful speed increase la usb2.0 vs 1


basic steps.
create a virtual hdd (usb.vmdk) which matches your usb location using command line tools.
add usb.vmdk as a hard drive in storage settings, make it as primary master.

mmm, i think that was it.
i also added a usb device filter under ports/usb settings, not sure if necessary or not.


again with greater verbosity :)
1. attach flash drive, then in disk utility unmount the partition of flash drive. step 2 will not work when mounted.

2. in terminal the command i used was (creating a virtual disk image in Documents folder) :
VBoxManage internalcommands createrawvmdk -filename /Users/admin/Documents/usbdrive.vmdk -rawdisk /dev/disk1

3. in  the virtual machine settings, storage.
add hard disk, then browse to the usbdrive.vmdk just created.
then change the attributes so the usbdrive is IDE primary master.

4. settings/port - add USB filter, browse to your usb drive.. this may only be possible if its' mounted ? which makes me think it an un-necessary step.

mmm, i think that was it.
i did find that OSX kept mounting th partition. if so then the VM wouldn't boot giving an error message about being unable to open image file. this is fixed by once again unmounting in disk utility (NOT ejecting).

------------------

note - the help manual (section 9.8 - Advanced storage configuration) also includes extra variables for connecting to partitions rather than the whole drive.
